A lot of hams like to carry a VHF radio. Of course, nearly everyone wants to carry a phone. Now, thanks to the kv4p HT, you don’t have to carry both. The open-source device connects to your Android smartphone and turns it into a radio transceiver. You can build it yourself for about $35.
The device uses an ESP32 and only transmits one watt, but it has lots of features like APRS and scanning. I do like the text transcription service that the phone provides, which is really great for those who can’t hear clearly.
I can see more and more now why having a 3D printer can be really useful.
