Atlas 210 and 215 output frequency change
 

I have some friends that have a few of these Atlas 210/215
transceivers, all with the same problem, which is noticable
nowadays with all the PLL frequency controlled radios on
the air.

they said these radios have no RIT.

but in SSB mode, on 40 or 75 meters, after tuning to a
frequency to the stations there, then going to transmit,
then their Atlas radios shift in frequency about 150 Hertz.

is there a cure to fix this this problem on these radios
that I can pass along to these people??
