We need new IF-DSP V/H/SHF radios with built in band scopes and modules up to 5GHZ.
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.
