That seems to be the latest, I also don't see a 500kHz option having just updated....

Apologies - I released it for the Portsdown 2020, and thought that I had already released it for the Portsdown 4, but I was wrong.

Just doing the final testing of the P4 version now.

Working well now :-)
Really handy having it cover 29.15MHz too, I can see how much I'm overdriving my amp.... ;-) [its not that bad really, RTL overload, its about -35+ in reality...]
