>Here's the info, straight from the Radio Free Europe engineers, for
>putting said radios on other non-standard bands...
>
>xtal freq= freq of desired band startpoint minus 8.895 (in Mhz)
>Example...desired range is 19.005--19.505mhz...xtal is 27.900.
>(27.9-8.895=19.005)
>
>Tune up...
>1)Insert correct xtal in socket--use a band nearest to the desired freq.
>2)Connect a VTVM, set on minus DC volts (5 or 15v scale) to test point A
>on the RF circuit board--towards the front of the board.
>3)Peak the appropriate Hetrodyne oscillator coil (should be about -5dc)
>4)Tune the RF amp coil to max noise or signal (if one is tuned in)
>5)Tune the ANT coil similarly...

>That's it.  I haven't checked to see if the three coils in question are
>different between the 310' and the 300/301'---they possibly are, but
>this may not make a lot of difference...

>I have tried these instructions for one out of band coil in my 310' and

>again, were from a typed memo that was placed in the "alignment" section
>of my 310' manual, from Radio Free Europe engineers...
>        Supposedly, RFE had a bunch of 310's--I wonder where they are
