It can be done if you can get it to tune on lower bands. Otherwise modifications will be in order.

Thank you for your great posts and for tuning into Best Smooth Jazz. If you would like a QSL send in your report to the email listed below.

SDR’s have the best sound out of the box.

Had a copy on the R-390A

Listening on the R-390A in SAM USB.

2214 with Papa by Paul Anka

Now in AM mode

2224 Sunglasses At Night by Corey Hart.

That would not surprise me. Thanks for the info.

0010 Low signal in the noise. The best reception of my radios including SDR is the Collins R-390A with the automatic sideband selectable synchronous AM stereo detector.

As far as stability on the R-390A I re worked the cosmos PTO VFO for mechanical stability and now after full warmup the drift is now 4Hz with the heaters off. Just amazing for a receiver that is 59-71 years old.

Nice. Just enough to bring down the signal around one frequency.
