Thank you, I do appreciate your explanation, Oh and nice to meet ya.. I did order a Sams manual and the 2nd item to check was the Ref Oscillator. Well that is bad .. another victim of the GLUE. As soon as I touched the solder joint the leg fell over. I ordered a couple and now waiting. I went...

LC - you mention pin 6 has a direct track from the VCO coil L13 which will help you confirm which pin is pin 1. I went back to the schematic to look at this and L13 direct track leads to pin 6 on UHIC007 IC1 - not 8719 IC2. I just want to confirm I am reading this correctly because I am the newbie.

Thank you for the detailed information. I would like to clear up the fact of pin 18 - this has been soldered into its thru hole. I have never taken it out or replaced it nor was it ever bent and soldered to trace. I mistakenly transferred my readings from the notebook to the computer in the...

Good afternoon, Yes I marked the original position and tried turning in both directions. It did not change any it stayed 1.74v. Then I returned it back to its original position. Thank you for the info on the 8719 and the cap kits. I will check on that book by Lou Franklin. I am aware of the...

Hi Handy Andy, The first diagram is the pin layout from the service manual I used. The 3rd diagram is the TB - #18 is near L50 and #9 is near D25. Did I do something wrong? When I transferred the numbers from my notebook to the computer for the voltages I must have transferred them wrong.. I...

Hi David, I will definitely recap, that is next while Im waiting for the other. Since you seem to do recap often do you have a suggestion on manufacture? I order thru Mouser.

Thank you I would like to proceed further into radio repair especially on the classics. So at some point I need the equipment anyway. I was looking on Ebay and around the other day for the PLL. When you buy one does it have to be programmed or anything or should it work as is?

Thanks again for taking the time to help out.. TP1 is at 36.6678 TP9 is 1.74v TP3 is 7.802usb / 7.798lsb TP1 should be 34.9875 TP9 should be 3.5v TP3 is right on target. As you might guess I am a newbie at this and trying to learn. I now know some of my issue with trying to step into the...

OK.. I soldered pin 10 in its proper location - #6 is still at 163mV - VCO I'm assuming is the Alignment for the carrier oscillator? Anyway Freq on target no alignment needed. Thought I would mention that MB3756 all voltages are correct but on IC1 UHIC007 pin 5 should be 3v but its only at 1.74v...

Thank you David you ae correct. I was wrong on the order. These are the correct readings... 1- 1.74v 2- 4.8v 3- 8v 4- 49.7mV 5- 49.7mV 6- 163mV 7- 4.3v 8- 4.7v 9- 8v 10- Not connected but solder pad goes to ground-should I solder this pin? 11- 8v 12- 8v 13- 8v 14- 4mV has continuity to ground...

Thanks for taking the time to read this. I picked up a TB Stalker XV base. When first plugged in it turned on, indicator lights and channel selector. I noticed there was no sound (yes the mic was plugged in) so I plugged into the headphone and external sp jack but still no sound (I do here...

Thank you everyone for the assistance. Now that I have that set I have a question regarding the modulation meter. The MOD/SWR meter works in SWR mode and in AM. When I switch to SSB the MOD meter does not move. RF meter is the only one that works when modulating in SSB. Is this normal for the...

Thank you

Hello everyone, I just picked up a Cobra 2000 GTL. It has been recapped and aligned. It currently has a dead key of 3w. I would like to decrease it as well as the modulation swing for AM and SSB. Can anyone help me with the correct location and procedure to do this?

OK so I have found a replacement transistor but their is a diode clipped and 2 resistors clipped. Diode is not in production anymore and I am having issue with the resistor as well. My question is that both the diode and resistors are there, so would soldering them back together where they were...

W2EKG not sure I understand your comment?? I just bought 2000 and didn't know it had mods done to it. I didn't ask my fault. Anyway I just wanted it to be back to original condition its more of a keepsake as a memory of when my dad used to be on the cb when I was a child. He had the 2000 and...

1 more shout out to Mikesradiorepair on Youtube, he has a vast variety of helpful radio repairs posted on this 2000 and what looks to be hundred other ones. Hopefully this string and the videos on youtube will offer someone else some much needed info for those of us who aren't electrical...

Wow both you guys (Nomadradio&Loosecanon)were a really big help. Thank you! I have managed my way through tracing the wiring back to the way it was intended. It appears to be only one transistor cut and 3 resistors in the same area as the crystal I just soldered back into the board. The service...

I have a 2000 that I am returning back to factory condition. I see that there has been several mods done and I have removed them. I currently am having issues with trying to figure out which wires go to the tone control and the voice lock control. I have very limited knowledge on reading...

Hi redlght I appreciate you taking the time to color code the schematic and post it. I am trying to restore my 2000gtl back to original condition. It has been modified and I have removed the modifications but need some help. So I need to attach the wiring on the tone and volume back to the way...
