Portable Amateur TV on 24 GHz this morning with @G8GTZ and G4LDR. Best DX was G4FRE at 94 km. G4LDR also managed a 47 GHz CW contact over the same distance. @BATCOnline @theRSGB

I've just added support for the @SDRPlay RSPdx to the @batconline Portsdown equipment. Spectrum and waterfall BandViewer for portable operation using a Raspberry Pi 4 and a 7 inch touchscreen. Software build here https://t.co/jORNfvUip4

Testing the @Icom_UK IC-905 on 23 cm FM ATV with @g4_klb through GB3SQ this evening. The video level was a bit lower than GB3SQ was set to receive but it certainly worked. Look out for the review in @theRSGB RadCom and further technical details on @BATCOnline CQ-TV

In this case the other stations rob a lot of power from the beacon, decreasing the transponder gain by 3.5 dB compared to an idle transponder, and greatly changing the power distribution from what I showed in the previous post. Read more: https://t.co/wMubN2aIDO (2/2)

Well worth waiting in the queue for the @Raspberry_Pi pop-up shop. Bought 2 Picos and gave a demo of the @BATCOnline Portsdown Amateur TV transceiver to the Raspberry Pi team
