[R-390] R390A and Q-multiplier

[Steve Toth]

Or...Grab and older used Icom R70 receiver (I have 3 I've accumulated over the years) - receives down to 100kc so you also get the extended receive range for the new 630 meter hamband as a bonus plus any low frequency stuff you want to explore.

Feed the IF output from the R390A into the R70 ant. jack
You get Pass Band Tuning, IF notch, adjustable AGC, Scope Jack, Line Output, RIT, dial lock, converter input jack, adjustable noise blanker and built-in preamplifier.  Makes a great SSB adapter too! - Steve  W7SJT

The poor mans solution is to feed the R390A 455KHz into a Hammarlund HQ-180X series receiver.  Yes, it would take up a lot of space even with the receivers on an offset angle.  Then again the HC-10 isn't really small.
Now if one was a real heretic and had lots of tools and skill, one could gut the HQ-180 and have a HC-10 DIY project.  But having a HQ-180C and having looked inside of it, the internal layout is such that doing that has a 99 44/100 percent chance of failure.
