Walt,

I took my SR-160 out of the cabinet to measure the voltage for you. There was a small #2 machine screw loose inside. So I am glad I got that out before it caused any damage.

The radio is powered from a BK Precision Dynascan Isopack Isolation Transformer 120VAC TR-110. I did the measurement with two AC input voltages.

With the input at 122.8 VAC
Receive 149.4 VDC, Transmit 148.6 VDC

With the input at 118.5 VAC
Receive 148.8 VDC, Transmit 148.1 VDC.

The measurements were made with a Craftsman auto ranging multimeter (982018). The least significant digit kept changing so I used the value I saw the most. 

73 Tom.

Looking for anyone willing to remove the bottom cover of their 160 and or 500 and check the regulated 150v line.



Tune up the transmitter for max power out. Monitor the 150v reg line. Note the voltage in receive and in transmit and let me know what you get.
