A first look at the KV4P HT

In this video I take my first on video look at the KV4P HT, a radio transceiver that turns your Android smartphone into a fully fledged 2-metre or 70cm HT. The device can be bought ready assembled from official sources listed on the KV4P HT website (https://www.kv4p.com/) or you can download the files to have boards made by JLCPCB or PCBWay, you would only need to obtain a radio module (SA818) and possibly the ESP32 device used as well as the SMD components can be soldered by the PCB manufacturers. The radio uses an app available in the Google Play store and only needs you to connect it using a USB-C to USB-C cable (supplied if pre-built but I found the cable with mine was causing my phone to think there was water or debris in the USB-C connector so if you have connection problems, try another cable. Assistance can be had on the KV4P HT Discord (link on their website) and there are helpful videos on the device on ‪@KV4P‬ 's YouTube channel should you get stuck. I've had one QSO using the device already with Chris M0WGC, one of the local amateurs, while I was doing some audio tests before I decided to start filming. The device is capable of APRS as well as FM voice, however you can't use APRS and voice at the same time unlike a commercial transceiver such as those by Yaesu, Kenwood and Icom that have the feature. I will be doing some further videos where I look at the power output of this device and taking it out to do some on-air testing, I'll also have a look at the harmonics though there are pictures of those tests on the KV4P GitHub so I expect it is going to be clean as these pictures show that. #hamradio #2-metres #VHF #KV4P #android Help support the channel, basic level for only £0.99 or early access for an extra £2.00:    / @paulmcgeem0wnu
