Retevis MateTalk L2 Review: PoC, Analog, and Remote Base Operation

The Retevis MateTalk L2 combines push-to-talk over cellular, or PoC, with a conventional VHF/UHF analog radio in one handheld. Four operating modes provide analog communication, network-based PTT, access to both systems, and a bridge between PoC and analog. Its feature list includes Wi-Fi, dual SIM support, Bluetooth, GPS, Zello compatibility, call recording, a 3000 mAh battery, and USB-C charging. Retevis also specifies an IP67 enclosure, an appealing feature for a handheld that may see outdoor use.

Retevis supplied two radios with AT&T service for this review. Over a few months, I have used them remotely from different cities around the United States, primarily with one serving as a remote base at home. That application has been the most interesting part of my testing, but the...

Introducing the XLXWDX Multi-Mode Reflector

The XLXWDX reflector is available to all ham radio operators. It supports D-Star, DMR, YSF, P25, and AllStar.

Module C is the shared conversation. Operators using different modes can talk together there: D-Star users connect to XLXWDX C, AllStar users connect through node 40041, and P25 users select XLXWDX / TG 31670 in their hotspot’s reflector list. XLXWDX is registered and appears in the Pi-Star P25 list. DMR and YSF users can also join C using the settings in the connection guide.

Module C also links to TGIF, a DMR network. Its default link is talkgroup 1375, “We Talk Football,” which is usually active on weekends and NFL game days. The dashboard has controls for changing C’s TGIF talkgroup or linked AllStar node; changes affect...

QK4 Mobile - Android & iOS Phones & Tablets - The most advanced K4 Remote app free!

In an earlier post, I mentioned that I had released QK4 Android mobile, primarily targeting phones. The app is now officially "QK4 Mobile" and supports both phone and tablet layouts for both Android & iOS. Best of all, it's open source and free!

The app now supports FT8/FT4 with a built-in app, which includes ADIF logging:

Ailunce HA2 APRS Functionality Revisited

When I first reviewed the Retevis Ailunce HA2, APRS was one of the radio's most interesting features, but it was also clearly unfinished. The radio could transmit position beacons and display received stations, but proper APRS messaging was missing. Incoming messages were treated more like packet comments, there was no way to compose a message, and Bluetooth access to the internal TNC was still a promised future feature.

The good news is that Retevis has now released new firmware that addresses most, if not all, of the missing APRS messaging functionality. I helped test several versions of this firmware and provided feedback about what the APRS implementation needed to do. After using the released version, I can report that all of the new messaging features described below work...

QK4 Android Mobile app: remote for the Elecraft K4 on your phone

I’m excited to share QK4 Android Mobile, a new Android phone-focused remote application for the Elecraft K4/K4D.

Source code and the Android releases are available at:
https://github.com/worldwidedx/QK4-Android

QK4 Mobile is a GPL derivative of Mike Garcia KF5O’s excellent QK4 project. The goal was not to reinvent the radio-control plumbing that QK4 already proved on Windows and macOS. Instead, we preserved the known-good K4 connection, CAT control, panadapter streaming, RX audio, and microphone TX architecture—and built a genuinely usable touch-first operating interface around it.

The challenge was that a K4 is a very capable radio with a lot of controls, and the regular QK4 assumes a large screen, keyboard, mouse wheel, hover behavior, and...

Radioddity GS‑10B Pro: Imperfect, Unrefined, and Surprisingly Good When You Use It Right

General Behavior and Everyday Use​

The Radioddy GS‑10B Pro is one of those radios that tries to cover a lot of territory. It’s a VHF/UHF handheld, but it also dips into HF, AM broadcast, shortwave, airband, and general wideband receive. It’s Radioddity’s attempt at making a “do‑everything” handheld for people who like to poke around the spectrum. Whether that’s good or bad depends on how you use it, because this radio rewards the operator who takes a little time to understand what it can and can’t do.

On VHF/UHF, the GS‑10B Pro behaves exactly like a budget wideband handheld should. It hears repeaters and simplex without drama. It’s not the most robust front end, but it’s not fragile either. Transmit audio is clean enough for normal use, FM audio is clear, scan speed is average...

Retevis RA89G: A Modern Take on the GMRS Handheld

The Retevis RA89G is the latest entry in Retevis’ GMRS lineup, and it brings a mix of modern features, solid ergonomics, and a surprisingly polished user experience. After spending time with it, programming it, and putting it through real‑world use, the RA89G ends up being a radio that does a lot right — as long as you understand what it is and what it isn’t.

Build Quality and Design​

The RA89G feels rugged in the hand. The chassis is stiff, the controls are firm, and nothing about it feels cheap or flimsy. Retevis clearly wanted this radio to feel substantial, and it does.

But let’s be clear: this radio has no splash or water resistance of any type. There’s no IP rating, and based on my teardown of the RA89R — the RA89G’s sister radio — there are no seals, no gaskets, and...
