Great video! The attached article is well worth reading. Very similar to calibrating scope probes to your scope with the internal 1 Khz square wave oscillator. W2AEW has a great video on that. I like your style of videos and the way you show your mistakes as well. Also, along with it's intended purposes, a $10,000 service monitor is a GREAT table for storing junk on. Merry Christmas, happy holidays, 73's and all that garbage too.
That's one of my EPROMs. I bet it's just got some oxidation on it. The sockets never go bad, but do come unsoldered due to board flexing over time, as they are surface mount. I'd reflow it. Also discord noises in the background, kek. It's IRC for people to dumb to figure out IRC.
The common failure issues with the power supply and power amplifier is centered around the fans seizing. Power supply fan fails...you have about 5 minutes to turn the repeater off before it cooks itself. PA fans fail...burns the PA up pretty quick. Of course the Quantro (Quantar with a MSF5000 PA) didn't have the fan issues with the PA due to it primarily being passively cooled like the MSF and Micor PA's that came before it and the Power Supply was also divorced from the Quantar backplane. .
My guy, the RFI shielding can pops you cut in were just perfect! Thanks for the effort and added touch, +1 sub!

this is awesome! great production quality and informative!
What a spectacular video - thanks for putting this together 😊😊
Oh, goodie!! Brand new channel with high quality interesting content!
My P25 hotspot is a Motorola Quantar! Slight overkill but wouldn't have it any other way! 73 de VK7HSE 👍
You just earned a new sub! Also, Santa needs to bring you some higher quality multimeter probes...

Before I see the rest of the video, stopping at the 15:42 point. Cold solder joint on the eprom socket? We will see…..
Any chance this is going to be going back on the air at Purdue?
