Radio had been through the ringer, changed electrolytic and tantalum capacitors, rebuilt PSU and PA. Everything seems to work ok, though it's one channel low & occasionally won't transmit. I can get to 27.285 by going to Ch. 29 and adjusting clarifier. Now and again the frequency jumps, I might be clarified to 27.285 and all of a sudden I'm almost a channel off. Sometimes the VCO goes out of Lock and I don't have any transmit or receive. Slight trouble adjusting L19 to see 3.0 Volts on 40 and 2.0 Volts on Ch. 1, though managed to get approx 2 Volts on Ch 1 w/ 3 Volts on Ch 40. AM Mode Ch. 1, Freq. counter to TP1, was only able to obtain 34.550 MHz, attempted adjusting L23 for correct freq. (34.650), core bottomed too soon. (was screwdrivered/chipped years ago) The traces around the MB8719 have been repaired, initially I thought issue could be related to programming input pins but they look normal. (Haven't verified the N code) Unmodified the radio, reverted it to stock and had it nearly aligned after making some changes, fine clarifier was out 1/4 of a turn. VCO block could have unseen corrosion, a few pins on the original PLL eroded away (it's been swapped now) It's possible that I changed crystal (X3) out when I undid the mods. My memory is not the best and honestly this point I really wish my friend did not ask me to unlock the clarifier after I had reverted the radio back to normal, but It is what it is and need to get it solved.. Pulled R44, D52. Removed brown wire from pot. Took red to constant 8V. I wasn't looking for a bunch of slide so I did not short out R174, nor did I take the yellow wire directly to ground. I don't have the frequency synthesis theory memorized... I can tell you at one point the counter showed 34 megahertz!? I believe all of this is due to the fact that several of the ferrite cores have been chipped, I'm having an issue with this alignment.
