With the proliferation of software defined radios on the market I am interested to hear what people think is the best for 137 / 144 / 440 / 1296 MHz use.
I have selected the airspy mini based on the fact
It's 12 bits It's got tracking filters It works with sdr sharp, hdsdr, gnuradio, gqrx
Has anyone bought out a satellite specific SDR ?
The funcube dongle is probably the best ?
I have a hack rf as well as rtl sdr and sdr play

Hello
For the best performance with vhf / uhf I would recommend the funcube dongle pro+ without hesitation.

Has anyone written software to allow the Funcube Dongle to be frequency controlled to compensate for LEO satellite doppler? For linear satellites, 1Hz frequency control would be required. For FM 1KHz would be ok. If it's not possible to control the actual FCD+ LO, it should be possible to control the baseband audio spectrum.
I first used the FCD+ as a panadapter with an FT-847 with LEO linear satellites.
More recently, I use (dual polarization) two (2) Funcube Dongle Plus SDRs for 2M EME and they are sensitive wideband (50 KHz) receivers. Frequency stability on 144 MHz is very good and easily decode JT65 signals bounced off the moon. No doppler compensation is used for 144 MHz moon bounce.
WSJT-X will control a commercial radio VFO to compensate for moon doppler. WSJT-X does not support control the FCD+ for doppler compensation.
The FCD+ is so widely used, I'm surprised that I have not found an application that will control the FCD+ and support doppler compensation.

SatPC32 will also control the SDRPlay with SDRUno the same way.
My linear satellite setup is a FT-817nd, a SDRPlay and a laptop running SDRUno and SatPC32. The radio communicates with SatPC32 via a CAT Bluetooth dongle. Make sure to add filters on each feedline to get rid of desense, if using an Arrow antenna.

Hello Paul,
Regarding software to control doppler on SDR:
For sats, I run HDSDR V2.76 using a generic SDR with RTL2832 Chip.
Running http://amsat.org.ar/pass.exe handles nicely SDR Freqs.
Seamlessly clicking any satellite, its Freqs+Dopplers are set on SDR.

Telling HDSDR to emulate (rtl dongle) a TS-2000 allows any program to control it. PSTrotator, Satpc32, etc.
I use VSPmanager (free for hams) to handle the virtual serial ports necessary.
Flex 5000a can use the same work around. Not all programs will control a Flex. Telling PowerSDR to emulate a TS-2000 allows the Doppler correction to be set, along with basic xcvr control.
Best SDR? Nooelec. The one in the aluminum box works best related to cost. Only downfall of the cheapie RTL's is that they drift with temperature. The aluminum box handles EMI/temperature swings well without a big investment.
Funcube dongles are pricy due to VAT. Nice, but not $200 worth of improvement, compared to the Nooelec.
Ettus B210 is a great radio. A fair amount of building is necessary to complete the project. Amp chips, power supplies, relays and the like. Doable, but assembly requires a fair amount of time, materials and energy.
All of them (except the Flex 5000a) are somewhat limited in the AGC department.

Andrew,
The Airspy Mini is a very good SDR, you have not made a mistake. At 1,296MHz you'll probably need a LNA.

I have selected the airspy mini based on the fact
It's 12 bits It's got tracking filters It works with sdr sharp, hdsdr, gnuradio, gqrx
Has anyone bought out a satellite specific SDR ?
The funcube dongle is probably the best ?
I have a hack rf as well as rtl sdr and sdr play
Andrew
I don't know what it is about the mini maybe it's the tracking filters but it works well

Well,
It's sensitive, has a good dynamic range (fewer problems from pages, FM Stereo transmitters) etc.

I have the "full size" Airspy, and it works very well. I've gone through half a dozen USB dongles, both Fun Cube dongles, the HackRF, and both SDRPlay units, and I like the Airspy the best.

I'm not really sure other than the ext 10MHz input, and a wider bandwidth.
I'd been through enough "dongles", and wanted something different.
The HackRF is only 8-bits, something I didn't expect for the price, and I had major trouble running the SDRPlay units with Linux.
