BTECH APRS-K1 Multi-Function Universal Audio Interface Cable - Supports APRSpro, APRSDroid - Android & iOS Compatible - Supports, BaoFeng, TYT, Wouxun, AnyTone, Kenwood, and More

I picked up the BTECH APRS-K1 Interface Cable to experiment with APRS and digital modes using my Btech BF-F8HP Pro handheld—and I’m honestly impressed by how much functionality you get in such a small, affordable package. ✅ Plug-and-Play Simplicity: Unlike more complex setups, the BTECH APRS-K1 is extremely easy to use. Just plug the K1 connector into your radio and the audio jacks into your phone, tablet, or computer running your favorite APRS or packet software. No drivers, no configuration headaches. It worked right away with APRSdroid on my phone. ✅ Great for APRS: I’ve successfully used it for APRS position beacons and receiving weather bulletins. It's an excellent tool for experimenting with analog/digital hybrids, and it’s especially handy for on-the-go or field use. ✅ Compact & Durable: The build quality is solid, and the cable isn’t flimsy like some other knockoffs. It coils easily and fits in a go-bag or glove box without taking up much space. ✅ Wide Compatibility: Works with most radios using the Kenwood K1 connector—including Baofeng, TYT, Radioddity, and others. I tested it with a BF-F8HP Pro and it worked flawlessly. 🆚 Compared to the Digirig: The Digirig is more powerful and flexible—it has a built-in sound card and can interface with many radios via USB, with full CAT control and rig monitoring. It’s great for WSJT-X, FT8, Winlink, and other digital modes that require precise audio control. However, it is double the price and you still have to buy $35 cables to connect it. However, the APRS-K1 shines in its simplicity and portability. No drivers, no setup, no extra power needed. Just plug and go. It’s perfect for APRS and analog audio modes, especially if you're working with Android apps or just need a lightweight field setup. 📌 Things to Know before you buy: This cable is audio-only—no CAT control or PTT over USB. It uses VOX, so your radio must support that (most Baofengs do). You may need to adjust mic gain and audio levels depending on your device and app. Final Thoughts: The BTECH APRS-K1 is a fantastic low-cost solution for APRS and audio-based digital modes. It’s not as feature-rich as a Digirig, but it’s also less than half the price and far easier to use in a field or mobile setting. If you’re looking to get started with APRS or dabble in analog digital modes, this cable is a no-brainer. Great value, great design, and super convenient.

This little piece of kit was just the interface cable I needed for my Repeater Auto-ID project. Have old PC dedicated to GMRS repeater, radio programming software, etc. Wrote a little VBS script to announce time and identity the station. Announcement audio is piped from 3.5mm headphone port to dedicated handheld (Wouxun KG-805G), Windows Task Scheduler fires the script at the top of each hour. Had to find the right mix of volume and VOX sensitivity level, but she's working great.

If your looking to work APRS this is the way to go with minimal investment. Can be used for additional AFSK and other audio transfers. Has built in limiter making setup audio into radio easier as well. Already have successful packets with ISS (international space station) and SMSGTE which enables radio to cell phone text communications outside of typical cell phone service. Baofeng tech are unique in being in U.S. And offering higher quality and official versions of items such as FTDI chip programming cable making more advanced setups much easier to accomplish again for minimal outlay. Have many items from them including genuine Nagoya antennas. Beware counterfeits elsewhere.

So I have purchased the EBay Easi-Digi interface for $40 and it does work great. I am in CERT and we are starting to use SSTV for sending images back to the EOC of damage from Disasters. As you can see from the image shown there is enough room to do your call sign for legality purposes and there is room for the Date and Time and room for USNG map coordinates so the First Responders know the Exact time/date and location the image was taken at. I wanted to try this cable out because it is half price of the EBay interface and my thoughts are more CERT people might be willing to give it a try if it didn't cost $40. Well I am having the same issues as everyone else. Once the SSTV App comes front and center off the radio goes keying up over and over every few seconds. Used a 3G and 5S iPhone, same issues. I tried it again last night and on a VOX setting of (9) the radio would not key up until I hit the "Transmit Image" button. I went ahead and set the VOX to (10) and the radio does stay off. It does bother me that it does this as the EBay interface does NOT do this and I can use a VOX setting of (1) with it. So I will test it further to make sure it doesn't mess the radio or the iPhone up. I contacted Btech for help with it but I am not sure they can do anything about it.

Plug and play for Vara FM over Anytone 878. I was skeptical it would work but it worked great right out of box.

Súper buen producto puede hacer mi propia repetidora de Zello a UHF..... es lo maximo

I wanted to like this cable for APRS operation on my macbook. Be warned that it's just not good. I returned the first one and tried another, but they're the same. The cable contains a sound card that processes the audio coming from the radio pretty heavily. I noticed a lot of distortion, but the biggest issue for me is it suppresses the audio level far enough that Direwolf can't pick up packets well. With my radio at full volume Direwolf reports that the audio is not quite half of what it should be. My computer reports it's about 25% of the max. It's very quiet. I know it's the cable because when I turn my radio down and then up quickly, the audio increases to full volume like expected, but only for about a half second, then the suppression kicks in. Also, about a half-second after a packet is received there is an audio volume burst, like the suppression is resetting itself. I don't know what kind of design went into this, but it doesn't seem good at all. I'm never going to be absolutely sure it's not a macbook-specific problem, but other audio sources I've tested don't do this at all. This is just my opinion, but if the computer end of the cable is USB-C, why bother limiting audio input? It's not like you're going to damage the computer at all. I mean, keep it from clipping, sure, but don't squash it down to nothing.

Excelente Producto gran Precio y Calidad

Works well thanks

resimdeki ürün yerine AUX ara ses kablosu geliyor. B-Tech markalı deği.direk boya markalı..

Item took 7 days to arrive. Item is made of quality material and working well with my HT. however price is high the high side.

Viene muy protegido y funciona muy bien. Lo he usado para enlazar la app Zello con un UV-9 Plus Baofeng y va de maravilla. 😃 Gracias.

Resimdeki gibi B-Tech APRS-K1 kablosu değil, Boya marka jak-lightning kablosu geliyor. Ürün hatalı. Amatör telsizci arkadaşlar uzak dursun.
