[R-390] "Sync Xtal Osc"

[jgedde at optonline.net]

To make sure I understand... So it's a mechanical adjustment for the crystal
switching?

Thanks
John

Hello John,

For both the R-390 and R-390A, it is to "synchronise" which crystal is used
in the 2nd Cristal Oscillator with the band in use.
This is a part of the adjustment procedure for both models.

There's a hole in my rear panel marked" SYNC XTAL OSC."  Visible through the
hole is a flat screwdriver plug in the xtal oscillator deck.  What is this
for?  I just noticed it today.
