Off-Grid ATAK Capabilities with the VGC VR-N7500 Bluetooth Radio

The VGC VR-N7500 is a 50W headless dual-band mobile transceiver that has quietly become one of the most capable off-grid ATAK radio platforms available for vehicle and overlander installs. With a built-in hardware KISS TNC accessible over Bluetooth, it removes the need for external TNC dongles or cables — and pairs directly with Android ATAK plugins to share positions, relay CoT data, and send GeoChat messages entirely without cell service or internet.

This post covers how the integration works, which plugins are available, what iOS users can and can't do, and the practical setup considerations.

What Makes the VR-N7500 ATAK-Capable

Most off-grid ATAK setups require an external TNC (Terminal Node Controller) to translate between the radio's audio and the digital data formats ATAK uses. The VR-N7500 skips that entirely. It has a native hardware KISS TNC built into the radio body, exposed wirelessly over Bluetooth SPP (Serial Port Profile). Any app or plugin that speaks KISS TNC can connect directly to the radio from an Android device — no cables, no adapters.

The KISS TNC capability was added via a firmware update in January 2025. Since then, users have confirmed compatibility with APRSdroid, RadioMail, and Winlink, as well as the ATAK plugins detailed below.

Other headline specs relevant to ATAK use:

50W VHF / 40W UHF — significantly more range than handheld alternatives
Headless design: mounts out of sight in a vehicle, controlled entirely via smartphone or tablet over Bluetooth
Supports multiple simultaneous Bluetooth connections (phone, PTT button, headset)
APRS, SSTV, and packet radio support
Android and iOS compatible for the native HT App (basic radio control only)

How the ATAK Data Path Works

The integration follows a straightforward stack:

ATAK Plugin on the Android EUD generates CoT (Cursor on Target) data — positions, markers, chat messages, routes
The plugin connects to the radio via Bluetooth SPP and sends data using the KISS TNC protocol
The radio encapsulates the data in AX.25 frames and transmits over VHF or UHF
Other radios in range receive the frames, decode them, and pass the CoT data up to their connected ATAK instances

Incoming packets from other operators are decoded by the plugin and appear as contacts, map markers, and chat messages on your ATAK display. The entire loop runs without any infrastructure — no repeater, no server, no internet.

ATAK Plugin Options

BTECH Relay (Open Source)

Originally developed for the BTECH UV-PRO, the BTECH Relay plugin uses the same Bluetooth SPP + KISS TNC interface that the VR-N7500 exposes, making it a strong compatibility candidate. It is free and open source, available on GitHub.

Capabilities include:

GPS position beaconing at a configurable interval
GeoChat relay between radio-equipped operators
CoT event relay — markers, routes, sensor data — with automatic fragmentation and reassembly for large packets
Optional AES-256-CBC passphrase encryption on all transmitted data
Persistent connection state indicator on the ATAK map
Auto-connect to last used radio on ATAK startup

TAK-UV-PRO (Open Source)

A fork of the BTECH Relay project, also available on GitHub, with additional features including APRS-standard SmartBeaconing — speed-proportional beacon rate with corner pegging — and automatic ping response with current GPS position.

GoTAK Radio Relay (Commercial)

A more advanced commercial option from Guerrilla Dynamics / GoTAK. In addition to basic CoT relay, it provides self-healing mesh networking across multiple radios in range, bridging between off-grid radio operators and TAK Servers or MANET networks. Operators who drop off the mesh are automatically rerouted through other nodes.

HAMMER Plugin

A fallback option that doesn't require KISS TNC at all. HAMMER acts as an acoustic software modem, transmitting CoT data through the radio's audio path — essentially encoding data as sound over any voice-capable radio. Throughput and reliability are lower than KISS TNC, but it works with virtually any radio.

Practical Setup Notes

Tablet as mission control. Because the VR-N7500 is headless, pairing it with an 8-inch Android tablet mounted on the dash gives you a large ATAK display alongside full radio control — a significantly better experience than a phone screen in a moving vehicle.

Bluetooth pairing quirk. The radio connects best when the app (ATAK plugin or HT App) initiates the Bluetooth connection, rather than pairing through Android's system Bluetooth settings. Pairing via settings first and then opening the app often results in the app not seeing the radio. Let the app handle the connection.

Power considerations. At 50W output the radio draws significant current — proper vehicle wiring to the battery with appropriate fusing is important, especially for extended off-grid use.

Antenna matters. The VR-N7500 requires an external antenna. For vehicle installs, a quality NMO-mount antenna on the roof will substantially outperform a magnetic-mount antenna, particularly for AX.25 data reliability at range.

iOS Support — What's Possible and What Isn't

This is the most common question and the honest answer is: iTAK exists for iOS and works well in connected environments, but direct radio plugin integration with the VR-N7500 is Android-only.

What iTAK offers

iTAK, developed by the TAK Product Center, is a free iOS app compatible with iPhone and iPad running iOS 14.1 or later. It provides maps, overlays, blue force tracking, GeoChat, and full interoperability with TAK servers, WinTAK, and ATAK. On a network — whether cell, WiFi, or satellite backhaul — iOS users are full participants in the TAK ecosystem.

The plugin limitation

iOS does not support the same external plugin architecture that Android does. The BTECH Relay, TAK-UV-PRO, and GoTAK Radio Relay plugins that bridge KISS TNC radios into ATAK simply cannot run on iOS. This is an Apple platform restriction, not a radio limitation.

Off-grid workarounds for iOS

The most practical workaround is to use an Android device as the radio-connected node and run a local TAK server (or hotspot) that iOS users connect to over WiFi. The Android EUD acts as the RF bridge — it relays CoT from the radio network to the local server, and iTAK users on the hotspot see everything on their maps.

For LoRa mesh (Meshtastic), a separate path now exists: as of February 2026, the Meshtastic iOS app includes a built-in TAK server, allowing iTAK to connect to a LoRa radio over Bluetooth without Android. This does not apply to the VR-N7500, which operates on VHF/UHF rather than LoRa.

Summary table

Capability	Android + VR-N7500	iOS (iTAK)
TAK app	ATAK	iTAK
TAK Server (online/WiFi)	Yes	Yes
Bluetooth KISS TNC plugin	Yes	No
Off-grid CoT via VHF/UHF radio	Yes	No (direct)
Off-grid via Android bridge node	Yes (bridge)	Yes (via hotspot)

Off-Grid Capability Summary

Capability	Available
Blue force tracking (GPS position sharing)	Yes
GeoChat messaging	Yes
CoT marker and route relay	Yes
APRS tracking (APRSdroid)	Yes
Winlink email	Yes
SSTV image transmission	Yes
AES-256 encryption (plugin level)	Yes (BTECH Relay)
No cell or internet required	Yes

Final Thoughts

The VGC VR-N7500 occupies a useful gap in the off-grid ATAK radio landscape. Handheld KISS TNC radios like the BTECH UV-PRO are more portable and cheaper, but top out at around 5W. The VR-N7500 brings 50W of output power, a clean vehicle install with no visible faceplate, and the same Bluetooth KISS TNC interface — making it the strongest option for vehicle-mounted off-grid TAK setups that need range.

The main constraints are the Android requirement for radio plugin integration and the need for an Android bridge node if iOS operators are part of your team. Within those bounds, the capability set is comprehensive: real-time position sharing, full CoT relay, encrypted messaging, and APRS/Winlink — all over VHF/UHF with no infrastructure dependency.

Control is direct and responsive. Head into a new bearing, watch the rotator track in real time, and get on with operating. Whether you're running a remote contest station or simply controlling a home antenna from the back garden with a tablet, the RT2 makes it seamless.

Function	Detail
Rotator Compatibility	Yaesu rotors (via RT1)
Connection	LAN / Internet
Control	Real-time remote heading, position feedback
Use Case	Remote beam antenna operation

A Complete System, or Piece by Piece

Every product in the Metrowpwr range works independently — but the real power is in how they combine. The wattmeters give you accurate power monitoring. The ZX7 gives you flexible antenna management. The RT1 and RT2 put your beam under network control. And the SPE interface ties your amplifier and antenna switching into a single remotely-operated station.

It's the kind of system that contest operators, DX chasers, and remote station builders have been building themselves from bits and pieces for years. Metrowpwr does it properly, in a coherent, supported package.

All products are available now. Contact us or visit the Metrowpwr product pages for full specifications, pricing, and ordering information.

The Tracker That Disappears Into Your Pocket

Seeed's SenseCAP T1000-E squeezes a GNSS module, LoRa radio, and 700 mAh battery into a credit-card frame — and costs less than a decent meal out.

Firmware

Meshtastic / MeshCore

There is a certain satisfaction in hardware that simply works. No IDE needed, no soldering iron on standby, no driver dramas. You take it out of the box, flash the firmware via a web browser, pair it over Bluetooth to the Meshtastic app, and that is that — you are on the mesh. The Seeed SenseCAP T1000-E is that device.

It is, by any honest reckoning, a remarkable amount of hardware for the money. At 85 × 55 × 6.5 mm — exactly the footprint of the card slot in your wallet — it goes anywhere without complaint. Jacket pocket, rucksack hip-belt, dog collar, bicycle frame bag. The form factor is not a gimmick; it genuinely changes where and how you carry a mesh node.

"The T1000-E is the tracker you keep forgetting you're carrying — which is precisely the point."

What is inside the card

The hardware story is genuinely impressive for this price bracket. Seeed have not reached for bargain-bin silicon.

MCU

Nordic nRF52840

The same low-power chip found in the RAK4631 and LilyGo T-Echo. Sleep current sits in the single-digit microamps — essential for multi-day battery life.

LoRa Radio

Semtech LR1110

Covers global ISM bands from 863–928 MHz. The LR1110 is a more integrated transceiver than the ubiquitous SX1262, with solid sensitivity figures.

GNSS

Mediatek AG3335

A dedicated, multi-constellation GPS module. High-precision positioning for real-time location sharing without any cellular dependency.

That Mediatek GPS chip deserves a moment. A dedicated GNSS module — not a software-defined approximation, not Wi-Fi triangulation — at this price point is genuinely uncommon. It is the sort of component that makes the overall proposition rather difficult to argue with.

Range and real-world performance

Range is where devices with integrated antennas typically take their lumps, and physics being what it is, the T1000-E is no exception. Without an external antenna, it cannot match a full-size handheld mesh node. That said, field tests have demonstrated reliable contact with base stations elevated over 50 metres, and solid city-block-scale coverage to vehicle nodes. For the use cases the form factor implies — personal tracking, asset tagging, lightweight mesh participation — it is more than adequate.

In urban environments, expect somewhere in the region of one and a half to two kilometres of practical range with obstructions in the way. Out in open countryside, rather more. The key insight is that a T1000-E riding in your rucksack, contributing to the mesh as a relay node whilst simultaneously reporting your position, is doing something no full-size node can manage from a trouser pocket.

The charging compromise

The one polarising design decision is charging. Rather than USB-C, the T1000-E uses a four-pin pogo connector — magnetic, proprietary, and the reason the device can be sealed to IP65. The trade-off is deliberate: the sealed casing is meaningfully more rugged than anything with a port flap, and IP65 means genuine protection from rain and dust. It does, however, mean carrying a dedicated charging puck, which some will find a mild irritant and others will consider a non-issue.

Battery life lands at several days on standby with GPS disabled, or roughly a full day with active location tracking. Use it hard as a repeating node with frequent position broadcasts and you will be charging it each evening — perfectly manageable, but worth knowing before you head out on a multi-day trip.

Getting started

Setup is refreshingly straightforward. Navigate to the Meshtastic Web Flasher, select the T1000-E from the device list, and flash. No IDE, no command line, no drivers. The device ships with firmware pre-installed, so for most users it is simply a matter of pairing over Bluetooth and selecting your region in the app — you will be on the mesh within minutes of unboxing.

The pogo pins also serve as a developer interface: USB, serial logging, and a DFU mode are all accessible there for anyone who wishes to dig into the firmware, or who wants to run it as a LoRaWAN asset tracker rather than a Meshtastic node — a separate firmware variant is available for that purpose.

Verdict

Strengths

Genuinely credit-card sized and pocketable
Dedicated AG3335 GPS — real precision
IP65 rated — splash and dust resistant
No-code setup via web flasher
Supports Meshtastic and MeshCore
Multi-day standby battery life
Clip and carabiner attachment included
Exceptional value for money

Limitations

Proprietary pogo-pin charging, not USB-C
No external antenna option
Range trails larger, external-antenna nodes
GPS-on battery life is roughly one day
No display or buttons for standalone use

9

/ 10

Final verdict

The T1000-E is the easiest recommendation in Meshtastic hardware right now. If you need a no-fuss tracker to keep tabs on a person, pet, or a piece of kit — and you want it to participate in the mesh whilst doing so — nothing else at this price comes close. The pogo charging is the only genuine friction, and even that becomes second nature quickly. Pick one up from ML&S, flash it, and forget you are carrying it.

SunSDR DX2 connection to MixW a guide..

1 June 2026

SunSDR DX — CAT Control with MixW2 & Omnirig | Gazlabs @import url('https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;600&family=IBM+Plex+Sans:wght@400;500;600&display=swap'); *, *::befo…

SunSDR DX — CAT Control with MixW2 & Omnirig | Gazlabs

SunSDR DX — CAT Control with MixW2 & Omnirig • Setup & Troubleshooting Guide

How It Works

ExpertSDR2 emulates a Kenwood TS-480 via ECATv1 over a virtual COM port pair. Omnirig connects to that port and acts as a CAT broker for MixW2. Audio routes via Virtual Audio Cable (VAC).

ExpertSDR2 (ECATv1) → Virtual COM pair → Omnirig → MixW2

Step 1 — Install a Virtual COM Port Pair

com0com (free) — sourceforge.net/projects/com0com
VSP Manager by K5FR (free) — k5fr.com

Create a pair using low numbers e.g. COM5 ↔ COM6. ExpertSDR2 uses one end; Omnirig the other.

Note: Enable Emulate baud rate in com0com on both ends — without it, idle silence is treated as a dead connection.

Step 2 — Configure ExpertSDR2 (ECATv1)

Options > ECATv1 > tick Enable CAT:

Setting	Value
Virtual COM port	COM5 (first end of pair)
Baud rate	115200
Data / Parity / Stop	8 / None / 1
Rig emulation	Kenwood TS-480

Step 3 — Configure Omnirig

Settings > Rig 1:

Setting	Value
Rig type	Kenwood TS-480
Port	COM6 (second end of pair)
Baud rate	115200
Data / Parity / Stop	8 / None / 1
RTS / DTR	High / High
Poll interval	100 ms (critical — keeps connection alive)
Timeout	4000 ms

Note: 100 ms poll means Omnirig queries the radio constantly, even when idle. Without this the connection drops on inactivity.

Step 4 — Configure MixW2

Configure > TRX/CAT > select Omnirig / Rig 1. MixW2 talks to the radio through Omnirig — no direct COM port needed.

Step 5 — Audio via Virtual Audio Cable

Install VAC from vac.muzychenko.net. Enable the VAC button in ExpertSDR2.

Program	Input	Output
ExpertSDR2	VAC Line 2 (TX from MixW2)	VAC Line 1 (RX to MixW2)
MixW2	VAC Line 1	VAC Line 2

Fixing CAT Drops on Inactivity

Drops when you stop tuning or change focus? Idle timeout somewhere in the chain. Work through these:

Fix	Action
1 Omnirig poll 100 ms	Set poll interval to 100 ms. Keeps traffic flowing so port never goes idle.
2 Windows USB power	Device Manager > Ports > right-click COM port > Power Management > uncheck allow sleep. Repeat for USB Root Hubs. Set Power Plan to High Performance.
3 com0com baud rate	Tick Emulate baud rate on both ends of the virtual pair.
4 Omnirig timeout	Set timeout to 4000 ms.
5 Switch to TCI/SDC	Replace ECATv1 with TCI via SDC. Most stable fix — see section below.
6 Update ExpertSDR2	Older versions had CAT bugs. Get latest from expertelectronics.ru.
7 Low COM numbers	Keep ports below COM10 — high numbers cause issues in some software.

Tip: If fixes 1–4 don’t solve it, go straight to TCI/SDC (Fix 5). It’s the only method confirmed fully stable by SunSDR DX users.

Advanced: Stable Connection via TCI and SDC

What is TCI? TCI (Transceiver Control Interface) is Expert Electronics’ native protocol for ExpertSDR2. It runs over a WebSocket on localhost — not a serial port emulation. Persistent, fast, doesn’t go idle.

SDC bridges TCI to a virtual COM port so Omnirig connects normally. ECATv1 is removed from the chain.

ExpertSDR2 (TCI/WebSocket) → SDC → Virtual COM → Omnirig → MixW2

Real-world fix: Customer tried every method — all dropped. Switched to TCI/SDC — instant stable connection. Catch: RIG Emulator was missing in SDC because the version was too old. Fix: find the cumulative update on the UT4LW site, get a reg key, update. Working version: SDC v19.06 x64.

Step A — Enable TCI in ExpertSDR2

Options > TCI > tick enable:

Setting	Value
Enable TCI	Tick
Port	50001 (default)
Address	localhost / 127.0.0.1

Step B — Install SDC (version matters)

Download from UT4LW website. If RIG Emulator is missing, the version is too old.

Note: Get the cumulative update — requires a registration key. Confirmed working: SDC v19.06 x64.

Add TCI Client → address: localhost, port: 50001
Add RIG Emulator output → assign to COM7

Step C — Point Omnirig at SDC

Change Omnirig port from COM6 to COM7 (the SDC RIG Emulator). All other settings stay the same.

Note: ECATv1 and TCI can run together in ExpertSDR2. Test SDC alongside your existing setup before switching fully.

Quick Reference

Standard (ECATv1):

Software	Port	Role
ExpertSDR2 ECATv1	COM5	CAT out (TS-480 emulation)
Omnirig Rig 1	COM6	CAT in (100 ms poll)
MixW2	Omnirig	Via Omnirig Rig 1
ExpertSDR2 VAC	VAC Line 1	RX audio to MixW2
MixW2 audio out	VAC Line 2	TX audio to ExpertSDR2

Stable (TCI + SDC v19.06 x64):

Software	Port / Address	Role
ExpertSDR2 TCI	localhost:50001	TCI WebSocket server
SDC TCI Client	localhost:50001	Connects to ExpertSDR2
SDC RIG Emulator	COM7	Virtual CAT port for Omnirig
Omnirig Rig 1	COM7	CAT in (100 ms poll)
MixW2	Omnirig	Via Omnirig Rig 1
ExpertSDR2 VAC	VAC Line 1	RX audio to MixW2
MixW2 audio out	VAC Line 2	TX audio to ExpertSDR2

I have seen a few people getting the dreaded Unknown USB Device (Device descriptor Request Failed) error when connecting their Yaesu FT5 to their PC. I should start by saying the supplied USB cable (YAESU SBR-36-MU) is for FIRMWARE updates ONLY. You will still need the SCU-57 for programming the radio. The PL2303 driver is also for the SCU-57. If you want to program the radio without the SCU-57 you will need to use an SD card.

Firmware update steps:

Remove the battery from the radio.
Move the switch on the back of the radio to the "Update" position.
Plug the USB cable into the radio and your PC.
Install the drivers (they are on the Yaesu website).
Connect the power to the radio.
When you are in the firmware update mode you will see the update screen, open the firmware update software. You can ignore COM port and Baud rate settings — just run UPDATE.
Wait. The software will look like it is not doing anything at first but it is. Wait a good couple of minutes and you will see it start to update.
When it is done, you're finished.

The manual is as unhelpful as ever, but hopefully these steps help you get your FT5 updated. Good luck!

If you are experiencing RTX 3080 crashes to black screen while playing ARK Survival Evolved, here are 12 things to try:

Update your GPU drivers — make sure you have the latest drivers from Nvidia.
Update your OS and motherboard firmware — ensure Windows and BIOS are up to date.
Disable antivirus and GPU software — temporarily disable any overlay or monitoring software.
Monitor your temperatures — use HWMonitor to check GPU and CPU temps.
Run a hardware diagnostic — test your RAM and GPU for errors.
Use proper power cables — do not use adapters or daisy-chain cables.
1000W PSU is barely enough — the RTX 3080 has massive power spikes.
Lower your game settings — especially shadows and textures.
Verify game files — use Steam to verify ARK's installation.
Use a single monitor — multi-monitor setups can cause issues.
Remove USB graphics adapters — these can conflict with the GPU.
Reinstall the game — ARK is 475GB, a fresh install may help.

I experienced this issue for a whole month before finding a fix. Hopefully one of these steps helps you.

Can Wide-banding a radio or modifying for mars-cap damage your radio? Why do people do it?

What is Wide-banding?

Wide-banding or MARS-MOD is the process of modifying a radio to transmit outside its originally designed frequency range. This is often done to allow amateur radios to operate on other services such as MARS (Military Auxiliary Radio System) or CAP (Civil Air Patrol).

LAW Issues

Modifying a radio for wide-banding may violate your licence conditions. In the UK, Ofcom regulates radio communications and any modification that causes the radio to operate outside its type-approved parameters is illegal. NOVs (Notices of Variation) in the UK allow certain exceptions but wide-banding is not typically covered.

DAMAGE Risks

Wide-banding can damage your radio in several ways: the transmitter may produce spurious emissions, the receiver may become desensitised, the front-end filters may be overloaded, and the power amplifier may be damaged by operating into a high SWR on frequencies it was not designed for.

MARS CAP Explained

MARS and CAP are US organisations that allow amateur radio operators to communicate on certain military frequencies during emergencies. Some operators modify their radios to access these frequencies.

FREEBANDING Explained

Freebanding refers to operating on frequencies between the amateur radio bands and CB radio (11 metres) without a licence. This is illegal in most countries.

CB / 11Mtrs

CB radio operates on 27 MHz (11 metres) and does not require a licence in the UK. Some modified amateur radios can operate on these frequencies but doing so with a modified radio is likely illegal.

IS LISTENING LEGAL?

Ofcom guidance on listening to transmissions can be found on their website. Generally, listening is legal but acting on what you hear or transmitting without authorisation is not.

Conclusion

Weigh the benefits of wide-banding against the risks. Seek expert advice and always comply with the law in your jurisdiction.

What is FT-8? can it damage your amateur radio transceiver?

What is FT-8?

FT-8 was developed by K1JT and K9AN as part of the WSJT-X software suite. It uses 8-FSK modulation with 6.25 Hz tone spacing and operates in 15-second intervals. It can decode signals 10 dB below the noise floor, making it extremely popular for weak signal communication.

Can FT-8 damage your transceiver?

No — FT-8 itself cannot damage your radio. However, improper setup (such as running too much power, using a poor antenna match, or operating without proper duty cycle management) can cause damage. Always ensure your radio is properly configured when running digital modes.

Difference between FT-8 and PSK-XX

PSK-XX (such as PSK31) uses phase shift keying and operates at higher power levels with wider bandwidth. FT-8 is more robust at lower signal levels and uses much less bandwidth.

Difference between FT-8 and FT-4

FT-4 uses 4-second intervals (vs 15 seconds for FT-8) which makes it faster but less sensitive. FT-4 also transmits shorter messages and is less robust than FT-8 at very low signal levels.

What is D-STAR?

D-STAR (Digital Smart Technologies for Amateur Radio) was developed by the Japan Amateur Radio League (JARL) in the late 1990s. It uses digital voice encoding for clearer communication compared to analog FM.

Radio Formats

D-STAR is available in handheld, mobile, and base station formats from several manufacturers including Icom, Kenwood, and Yaesu.

Data Capabilities

D-STAR supports data transmission, text messaging, and GPS position reporting in addition to digital voice.

Getting Started

Get a D-STAR compatible radio.
Configure the frequency, mode, and code settings.
Connect to a local D-STAR repeater.
Make calls and disconnect when finished.

No Repeater Nearby?

If you don't have a D-STAR repeater in range, you can use a digital hotspot like the Zumspot. These devices connect to the internet and allow you to access the D-STAR network from home.

A Zumspot is a small device that runs a D-STAR reflector client. It creates a personal digital repeater that connects to the internet, allowing you to communicate with other D-STAR users worldwide without needing a physical repeater.

The FT-710 doesn't really need to "fit" in the range — component shortages are forcing manufacturers to rethink their lineups. The FT-710 uses the same FT-991A chassis and the same key elements as the FT-DX-10 receiver, probably with some component substitutions.

It's good to see Yaesu pushing out new radios yearly.

The FT817 held the QRP portable crown for 23 years. Now the IC-705 is a serious contender with its colour screen, USB/WiFi/Bluetooth connectivity, and 10W on external DC vs 6W from the FT-818ND.

Comparison

Price: IC-705 is almost double the price
Weight: IC-705 is twice the weight of the FT-818ND
Portability: FT-818ND is better for backpacking (lighter, sleeker)
Features: IC-705 is better for picnic table operating

Power

At 5-6W USB voice, antenna and location matter a lot. The extra 4W from the IC-705 on external DC can make a difference.

Conclusion

Choose the FT-818ND for portable/backpacking use. Choose the IC-705 if features are your priority.

I bought my RE Himalayan in October 2021 and just did the 300 mile break-in service during the UK winter.

The Struggle

There is a lack of RE dealers near London. Bike Shed Watford went bust. The nearest dealer was a 120 mile round trip. Storm Eunice forced a cancellation.

A colleague suggested Hatfield's Of Crowthorne — only 40 miles away. Got the service done during the storm.

The Result

£30 less than I expected to pay. The Himalayan was a champ in the storm — very sure-footed in the bad weather. If servicing stays this affordable, it's a keeper.
