I got the radio opened up this morning and finally located both TP1003 and the T1009 adjustment.
?
It looks as though someone has 'technified' this rig before I got to it. I found a single copper-coated spring steel 'finger' like one finds on radios that ensure the case is grounded to chassis ground. But just one.. and nowhere else in the radio were any like it and no place that looked like one or more had broken away.
?
I found there to be? 0.07 vdc on TP1003 regardless of state of RX or TX.. no change. This was with CW mode selected and RF power turned all the way down. I tried to bring pwr up to see what might happen with the voltage at TP1003.. While the radio still shows going into TX mode, no power is displayed on the S/PWR meter on the radio and none on the wattmeter I had between the radio and the dummy load.? And the voltage remained unchanged regardless of RF pwr control setting.? Then I discovered that the T1009 control was already maxed out (fully clockwise). I tried backing it off and the voltage at TP1003 decreased from 0.07 all the way down to 0.00.
?
I can hear the relay click on TX but still not even a flutter in voltage.?
?
I just get the feeling the problem is a lot deeper than a VCO adjustment. I'm still open to suggestions but I'm about ready to give him the bad news.? If he can find someone honest, that works on these things for a living, he might still be okay with it but it doesn't appear that I'm the guy for the job. I'm a hobby-level tech that works almost exclusively on old/vintage tube gear. If I HAD a pay grade, this would be above it?
