For #1, the manual is correct. There could be several reasons you show no current. Check all the voltages according to the voltage chart.
For #3, that's not normal and I've seen this before. The crystal oscillator and/or VFO is not oscillating. You are not hearing on the frequency you think you are. Check those. 73, Bob WW3QB --- On Tue, 10/5/10, Donley <[email protected]> wrote: From: Donley <[email protected]> Subject: [Drakelist] Drake TR-4C To: "drakelist" <[email protected]> Date: Tuesday, October 5, 2010, 2:13 PM I am trying to put my TR-4C back on the air after many years on the shelf. I have a few problems and questions for now. Maybe more later. 1. The bias adjustment procedure as listed in the manual does not work. The bias current reads close to zero and does not change with adjustment of the bias knob. This is true of two different power supplies that I have. Is the manual correct and what am I doing wrong? 2. The USB and LSB indicator lights are very dim and difficult to see in normal lighting. The bulbs seem to be bright enough but the red plastic lenses are eating up the light. Any fix for this? 3. The crystal calibrator works very nicely when adjusted to zero beat on the calibrated frequency. However, if I move away from the calibration point, the calibrator still has a steady signal at about 500 to 700 Hz (estimate only, my ears are shot). The signal goes away when I turn off the calibrator. Is this normal? Thanks.
