Ok thanks. I am getting 13 volts at TP 7 and 8 as well as at the center leg of the driver. But you are saying that I could get the voltage there but something between the stems and the collector is not allowing the current to flow? If so guess I don't get how the voltage could "get through" but...

What should the voltage be between c157 and the base of driver on TX? There is 8 volts into c157 from the twisty of L44 but the other side is showing 0.7 to the jumper and then to base of driver.

Ok so with my frequency counter I am getting 27.189 (which is what the radio channel is set on and what the radios counter is showing) all the way from the base of the pre driver to the “out” of L44 to C157 to the base of driver. That’s as it should be, correct?? But still there is no RF...

ok will check it out. What is that cap soldered to the solder side of the board at L44? Is it possible that C203 was not even installed in my radio? If so, should I leave it out or out one in (as I did)? Do you think the 45 MHz rogue signal is being caused by something at the L44 area?

Yeah problem is I got that replacement from someone on here so I don’t have the donor radio to look at those other parts. In my radio, I don’t think C203 was even present. Is that possible? I saw the holes for it but was curious why it looked like nothing was in there. I stuck a 33 Pf in...

Yeah there still is yellow glue like stuff still stuck to it. Was afraid to pick it off in fear of damaging it. But I will attempt it.

Very frustrated. Can’t figure this out. Voltages seem to be ok through the circuits but there is no current. I just don’t know enough to know where to check. And when I do check, I’m not always sure if the reading I get is good or not (per my earlier post). Just to many potential places I...

Thanks I got it. I actually had that already but I appreciate it.

Sorry that doesn’t open. Says it’s corrupted or damaged.

So at the base of tr39 frequency is spot on agreement to the radios frequency counter (27.189). The p to p reading is jumping all around. Between about 0.15- 0.23 volts. The p to p reading at the base of the driver is 7.5 volts. The Sam’s says should only be 0.6! I get 0.7 with my VOM meter...

Yes I believe receive it good.

I do have an external frequency counter. Just gotta see where to hook it up. I’m not very proficient at using the scope but I can manage.

Yes there is definitely 8 volts all through those points.

Ok how do I confirm that? I used the scope and it does look like the carrier is going through the circuit. I probed at the predriver collector to the “out” of that coupling coil at C157 to the base of the driver. Seems to be a signal all through there.

All sounds reasonable thank you. Will explore that area a bit. I do have a scope. Curiously I had an issue with L44 previously so perhaps there’s still some kind of problem in that area.

Thank you, very good explanation and I totally get it. Just have no idea why/where that driver/final turn on isn't happening.

Another point not sure what this means. The red wire coming off the AM regulator to the switch says it should be 6.8 or so. But it is showing 13.0. When I lift the emitter leg off the pad there, it shows 6.3 which is fairly close but the pad shows 13 which of course is why the red is showing 13...

Yep, there is about. 0 .7 at both bases.and yes that is what I was thinking too The fact that there is no bias current was why the voltage is staying high all the time regardless of mode. I can hear a weak carrier on my other radio but no wattage reading at all.

Yes, the Transmit light does come on when I key the mike.

Ok well I am back!! Got the new mode switch in. Voltages seems to all be restored at the switch and TP 7 and 8. But I still have 2 problems: 1 there is 13 volts at the collectors of both the final and driver on SSB and AM transmit. It should only be about 6-6.5 on AM transmit. The base of...
