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.

Martin has moved along English Road. Wilder is one space east of Tracy City.

Dan's Martin / Morgan cavalry combo heads west to discover that my Wilder is protecting the road to Tracy City. He also now knows there is nothing else hidden in that area. Tracy City is the 8th VP-worthy railroad station we both missed when discussing the scenario. #GCACW #BAtC

This weekend I visited @emfcamp.bsky.social in the UK. The #AMSAT-UK / #BATC / #UKuG village had more visitors than last time and we uplinked live video to the #qo100 geostationary satellite.
I had such a blast!
Thank you for visiting our village and the talks by Dave G4DPZ, or for tuning in!
