[R-390] R-390 and "headin west.."

[blw]

John,

Try tuning the radio per the A -10 manual. I don't know about the nonA
manual, but I bet it is the same procedure.

1. Decide on your filter setting (4 kHz for this example)

2. Put the BFO selector to half of the filter setting (example- 2 kHz for
USB)

3. Off tune your desired freq by what the BFO is set for  (2 kHz up for USB
or 2 kHz under for LSB)

4. Example- you want to tune to 6.955 USB with the 4 kKz filter. You would
set the BFO to -2 kHz, and tune to 6.957 mHz. This should put you real close
to the freq of 6.955. You probably won't need verification of your frequency
as this is reliable.

Learn your particular radio. My USB is a few kHz off, so I fudge that error
in every time and I get dead on when I check frequencies. I can get accurate
logs every time.

If you try it all of the variations you can with tuning/off tuning, BFO
adjustments, etc, you will probably find the best audio and very accurate
tuning using the -10 manual directions.

Hope this helps,
