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. Mean while, please be award 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 separating at least two inches will also cure the hum. When full information is available, we will follow up.
Please advise your Service and Sales personal.
