Having used both the RTL dongle and a FunCube Dongle Pro (not PLUS), I'd say the FCD, hands down. Keeping RF out of it is manageable. On relay to switch between TX and RX input. Another relay between RXinput and the FCD which switches to a dummy load on transmit -- doubles the isolation.
AND, use a sequencer, so the relay switching is done before the transmitter is ever keyed.
Your transmitter will approve.
Good luck & 73, Jim wb4gcs@amsat.org

Steve, I spent almost three weeks until I was confident enough with the station, computer, software and connections to use the FCD for the linear satellites. Lasted two weeks. Do suspect that some RF made it's way down the downlink coax and gave the FCD RF amp a knockout blow. Tried to listen to ANTELsat this am. Couldn't hear it. Wasn't sure what the problem was. MANY VARAIBLES!!! Turned out to be the FCD. Was able to reconfigure the station to use another radio so that I could prove the bug. I can try the RTL SDR I got from ebay tonight and let you know how it stacks up. Norm n3ykf

So the Million Dollar Question (actually, I guess it is the "$180-higher cost + shipping" question) is whether the Funcube Dongle is significantly better than one of the cheap $20 RLT-SDR tuners? I have been experimenting with the cheapo version the last couple of days, and so far I have been able to pick up my local repeaters fairly well with a mag-mount antenna. I tried to pull in AO-73 late last night with an Arrow and a preamp but had some issues with SATPC32 that I have since resolved. I am pretty sure I heard something but I am still getting used to using SDR#. I need to do some more tuning.
I am going to keep on working with this, at least for the next few days, but should I just plan on shelling out the money for the Funcube Dongle if using the computer to receive the linear satellites is my long-term plan?

It'll receive Wx sats with the final IF at 50kHz width, FM demodulation. Some modes/software packages are more configurable than others. Using HDSDR here. Be aware that there are several versions of the FCD. The newest are the best, by miles. Use these with transmitters at your own risk. I killed one of my two, this morning, this way, I think. Most of the time I was using 5W from a handie scratchie. YMMV! SDR is the wave of the future. Being able to click anywhere in the passband of the receiver and then having Satpc32 go there while driving the transmitter rocks. The only better feature is that finding elusive signals became way easier. There's a stocking Winradio dealer less than an hour from me. Bad news: $800 plus tax.
