Ok, so……turns out, user error. ?I learned a lot and had some realizations while I was typing this email to tell you what my readings were. ?It left out what frequency to set the signal generator to, so I set it to the frequency it populated on the screen, which generated a signal but no audible tone. ?I had to off set it by 15hz like all the other sections instruct to do. ?That made the adjustments reasonable.

Now I was able to successfully get it aligned. ?Much better now. ?I will do final checks tomorrow. ?Only thing left is the SWR-2 section of the alignment, but I need to set up a 100ohm dummy load for that part.

Thank you for your willingness to help! ?And to correct myself from earlier, the Motorola R2600 is able to do just about everything. ?I do like the precision of the CMU200 as an SSG for the transmitter alignments.

I know you shouldn’t have to do alignments on them unless there is a problem, but this radio was originally deemed irreparable and I did extensive work on it. ?So I felt better about it after going through the whole alignment procedure before gifting it back to my dad to ensure it was at its best. ?

Hi I have replied a fair few of these radios, all with 100% success.

With regards alignment I have never had to pefrom this on received. I have set up the bias on PA transistors after replacement, which is also rare.

Unless you have a professional RF signal generator it is hard to aligned the RX, one reason is when you set levels down at -120dBm you get leakage unless the the signal generator is professional. ?10,000 plus!

The new siglent RF signal generators only go down to -105 dBm fir this reason of leakage.

You also need a decent audio signal generator never use a PC or laptop.

99% of the time, if you need to realign it is because some has twiddled it.

I was using an online tone generator and an oscilloscope to look at the amplitude.?

So I'm going to give it another go with a real signal generator and, as you suggested, shielded cable up to the MIC connector.

I'm thinking of skipping some of the other steps.? One set seems to be meant to calibrate the radio's internal output power meter; that seems accurate enough already.? But I don't know how to check if the APC is working correctly.? The ALC bar is orange and at half scale.? If APC was reducing my TX power due to excessive drive, the ALC bar would have some red on it, right?

I have and its fine, still shows 100w on all HF and 6m, just the power level on the radio drops one bar to just below 100% just a strange one, it has no affect on the output power at all
