Here is a typical and very recent post to the softrock40 group.<br>
----------------------------------------------------------------------------------<br><p>Eric,<br>
<br>
There are really only three good reasons to do this:<br>
<br>
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.<br>
<br>
2. You have a transceiver to which you'd like to add a panadapter
(or an additional wideband RX mode).<br>
<br>
3. You have a receiver for a frequency that is not covered by a
SoftRock (and want to add a panadapter or wideband mode).<br>
<br>
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.<br>

using a Softrock or other radio to monitor a selected

advantage? For example, if I had a cheap auto broadcast

kit to tap into the IF, how would I do it, and what would

Not at all, I have a Softrock 40 lite that I can plug into Janus and use
with PowerSDR. No other rig involved. I wasn't aware that there were also
units to hook up to the IF of other rigs. I'll look into that, thanks!

Preaching to the converted. I misconstrued that you didn't know about
the the Softrock IF.
