Just spotted this teaser for a new amateur transceiver. A very compact and
rugged design with two surface mount boards and built-in antenna tuner.

I'm not sure about the choice of connectors but I guess they're going for a
rugged water resistant exterior.

Personally I'd love to see something along these lines with a single USB
port carrying control, audio and IQ but in a way that it can be

for consumer radios covering LW, MW, SW and FM with DRM and analog
reception.

The DRM receivers I've tried so far have had terrible battery life and been

Here's a very handy little board for AU$16 from Banggood. They call it a
Wemos® NodeMCU wifi for Arduino. It's an ESP8266, which can be programmed
using the Arduino tools with an on-board 128x64 0.96 inch OLED display.




The library you need to drive it is here.

The trick is to download that Git repo as a Zip and then in the Arduino
software install the library from local Zip.
