[Premium-Rx] Premium Rx I & Q outputs

[Jack Smith]

One solution would be to use a Softrock receiver, and one of the several 
software programs to process the Softrock output. Softrock to connect to 
the 21.4 MHz IF out.

The Softrock has an I and Q analog output that is then fed to a PC 
soundcard for processing by software. The available software gives you a 
variety of detectors.

The advantage of a Softrock receiver is that it is very inexpensive, so 
if you decide this is not something you care for on a long term basis 
you are out practically nothing.
