The solution is to use a SDR on the IF of your current radio.  Then 
software can provide DSP, filtering, spectral and waterfall displays, 
decoding...etc.
I am testing the SDR-IQ using the 28-30 MHz output of the DEMI 144/28 
converter.  144-MHz is very commonly used IF for microwave converters.

For instance, I have transverters for 1296 and 10,368 MHz and 
converters for 2401 MHz.

SDR's are showing up more frequently these days.  Checkout Flex 
Radio, RFSpace, and Ettus Research.
