Perhaps your iPhone needs this adapter? It should have come in your package.As for the radio getting hot, is it transmitting continuously without a break? **Q: I bought this the aprs-k2 cable and am connecting an iphone 5s and a uv-5r. why does it always activate vox and intermittently transmit?** A: I use an iPhone 5 (not 5s, though) and a UV-5R, and I've found that I need to find just the right volume settings on both the phone and the rig. On the phone I have the volume set at about 2/3 and on the rig it's set at about 1/3. I also set the vox to 4. This cable actually solved the vox tripping problem I had when trying to do APRS with my iPad instead of my iPhone, so I know the circuit can do the job with the right settings.

B-Tech markalı deği.direk boya markalı.. ### ⭐⭐⭐⭐ Review *by A***S on 8 January 2022* 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. ### ⭐⭐⭐⭐⭐ Review *by A***G on 15 July 2025* 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. ## Frequently Bought Together - BTECH APRS-K1 Multi-Function Universal Audio Interface Cable - Supports APRSpro, APRSDroid - Android & iOS Compatible - Supports BTECH, BaoFeng, TYT, Wouxun, AnyTone, Kenwood, and More - SABRENT USB External Stereo Sound Adapter for Windows and Mac.
