[hpsdr] ozy/janus as soundcard for digital modes

[Sid Boyce]

Here is a typical and very recent post to the softrock40 group.

Eric,

There are really only three good reasons to do this:

1.  You have a very high-end (RX/AGC spec's exceed SoftRock) 
single-signal radio to which you'd like to add a panadapter or an 
additional wideband mode.

2.  You have a transceiver to which you'd like to add a panadapter (or 
an additional wideband RX mode).

3.  You have a receiver for a frequency that is not covered by a 
SoftRock (and want to add a panadapter or wideband mode).

I think #2 is the most common reason.  I can't for the life of me 
understand why someone would want to add an IF tap to an average (or 
worse) radio when the Ensemble RXes are so inexpensive and easy to assemble.

73,

    I keep seeing folks who are using a Softrock or other radio to
    monitor a selected receiver's IF output.  I'm not sure how this
    works or the advantage?  For example, if I had a cheap auto
    broadcast band radio with 455 Khz IF, would I be able to use this
    kit to tap into the IF, how would I do it, and what would be the
    advantage?
    Thanks,
    Eric
