The Portsdown main menu. Operation can be from 70 MHz to 3.4 GHz, in the allocated bands. As you can see, the cut-out for the touchscreen isn't my best work; sadly I don't have a 3D printer, which would've made things cosmetically better. Not essential, but it could do with a grille over the loudspeaker cut-out, I've yet to find anything suitable.

My latest project, a Portsdown 4 DATV RF transceiver, which also doubles as a Langstone multimode RF transceiver, using a Raspberry Pi 4. This is the control/display/interface circuitry, it requires an external ADALM Pluto SDR for the RF side.
