I installed it myself with the techs instructions. Dropped right in. I'm only a sparky, not a tech, so she kept the instructions basic for me. I was trying to avoid shipping a quite large box of 40+ year old electronics to them (2500 miles each way!) to save some $ if I could, and to prevent...

The Microchipz VCO11 worked fine for me, as mentioned in my first post in this thread. Radio is still working great 10 months later, spoke to the owner this morning on the local call channel (35 lower). So the Microchipz one will work in the Superbase. If there are other issues (bad caps, bad...

Sorry for the delayed replay, wanted to ask out tech why they may had had trouble. The RF board has pins that connect one side of the board to the other and these are a common source of trouble. It's possible that one or more of those was disturbed when they replaced the VCO. I can only speak...

Had a VCO on a Superbase die here. Radio was recapped and worked great for a few years, then one morning no transmit or receive when it was turned on. After about a hour it came good but 5 minutes later died again. TP1 voltage stuck on 5.4v and moving the VCO screw made faint sounds in the...

Last I heard (last Christmas) mom and bubs were doing well. She occasionally pops up on TM1 to answer a question, but is not doing any actual radio work for now.

There was about 10 of those done, and can confirm the mod works. Bang on 12 o clock clarification from turn on, cold night or hot summer day doesn't shift it. It just shows the radio makers can make radios that stable but choose not to because of the assumption that their customers either...

Do you have SAMS CB-139 in the collection?

Love my Kraco base, my first real base (all in one with power supply) radio about 40 years ago. Sold it back in the day, regretted it for decades. Found another one in nice cosmetic condition a few years back, sent it to techs for a partial recap (10V electros) and channel conversion. Now...

Here you go, schematics, parts location drawings, and parts lists. Pace and kemtronic versions are identical except the Pace comes as a 23 or 40 channel radio and the kemtronic has only 18 channels, only difference is the dial and channel switch. A common mod in the day was to make the 18 and...

No probs, I'll scan them in after work and upload it here.

I have the circuit diagrams (main and pll box) and parts location drawings for both too, can scan and upload them if you can't find anything yourself. Have the owners manual too if you want it. They are in good condition so should scan up nicely. They are for the 18 channel australian...

Seconded on the micro and one of those little purple Si5351 boards. We had a Kraco base done that way a couple of years back, works great and covers 120 channels (40 up and 40 down) with 10k and 5k drop switches. It's been my daily driver base since then, works great and less noise than the...

One of the techs we used to use was working on something similar for the Uniden HR2510. They had a lot of spare time at the tail end of the COVID lockdown era and were working on a replacement display and controller combo to give it things like repeater splits, scanning, user programmable...

The newer President McKinley has LCD screen too, probably because it's cheaper than a real meter / LED display. May last OK in colder weather areas, but will prematurely die here (Australian desert).

My 1998 Toyota Landcruiser's black and white screen still working fine 26 years and 325,000 km (about 200,000 miles) later. Wife's 2013 Toyota Corolla has a fancy color one, that one is still working too, but only half the age and mileage of mine. Had two Bearcat 980's purchased new. Screen...
