BULLETIN # 36
MODEL: TS-180S
SUBJECT: ERRATIC DFC / HUM WITH PS-30


Some TS-180S users may report erratic DFC and audio hum.  You will find
they have placed the PS-30 to the left of the transceiver.  Hum is induced
from the PS-30 into the DFC.

We are awaiting modification and production changes.  Meanwhile, please be
aware of this problem.  Temporarily moving the PS-30 to the right hand side
of the transceiver will cure the problem.  Spacing the two units with the
SP-180, or just seperating at least two inches will also cure the hum.
When full information is available, we will follow up.
