Hello All
I got a problem with a TR-4CW.
When I switch from SSB to X-CW I only get a very little bias current on the
meter.
Less than 50mA.
Even when I turn on the Bias potentiometer on the AC-4 nothing happend on the
meter.
But when I turn the Bias potentiometer back and forth around -55 VDC I hear a
weak click inside the TR-4CW.
It sound like a relay is activated or something like that.
But I can not achieve 100 mA as required.
Is someone able to inform me where to look.
Thanks in advance.
