[amsat-bb] SDR radio

[Brad Brooks]

Yes Patrick, To clarify I have used both the DXPatrol and FCDPro+ but in RX duties only thus far. I am configuring a tracking panadapter on my RX side, so I will look for degradation when TXing. My progress/experiments have been delayed due to flu and weather.

I find the DXPatrol to be better performing than a generic RTL dongle, of which I have several. Even the FCDPro+ suffers from front-end overload in my location unless I use an FM BCB filter in front.

I also intend to use a duplexer unit in front of the SDR if 2M overload is experienced.

I will keep posted if there is interest. 73 Brad WF7T
