Yes, I meant tuning range, sorry.
?
A little more background.? Fifteen years ago I built a 40m SSB receiver from a Softrock, analog I/O, and DSP written in VHDL on a Spartan-3 FPGA.? That was my introduction to SDR.? What I'd like to do now is approach the problem again, starting with the QRP labs modules and designing the DSP in C on a microcontroller. Reinventing the wheel, sure, but the fun is in the experimentation.
?
As a bonus, I though it might be fun to see if I could make a VHF (FM broadcast, NOAA, 2m ham) receiver.? That's the reason for asking about the wider tuning range.
?
Thanks,
Eric
