BULLETIN # 46
MODEL: TS-520
SUBJECT: CW FREQUENCY SHIFT

Reports of intermittent frequency shift during CW operation, on the order
of a few hundred cycles, may be traced directly to the Carrier Unit.

On the Carrier unit X50-0009-01, install a ground lead of #18 tinned wire
or similar, between the cases of T1 transformer and X3, the LSB XTAL.
Recheck frequencies after installing this ground lead.


Please annotate your service manual.
