Could be. It's hard to know.

Well, making a copy of everything and putting it on another server will preserve what exists, and enable repair without jeopardizing anything.

Standing Wave Ratio. It is a measurement of how much of your signal is going out of your antenna to how much is bounced back to the radio. A theoretical perfect match is 1 to 1, but in reality you are okay as long as you are under 2:1. The lower that reading is, the more power is being...

I second the notion of finding the size of the fan first. Often, a ball bearing fan will be used, which is great for longevity, but not so great for being quiet at low speeds. It could also be that a sleeve bearing fan was used, but after aging, it gets louder. I would say to try a sleeve...

There are multiple options to fix that forum. We have no ability to do anything without contact with the owner though. I can think of multiple things to attempt to try and fix it. Looking through the code on github, it doesn't look like they are writing tests for their software, which would...

I don't have much time, but I am a software engineer, and have tons of experience unscrewing databases. If anyone gets access to the stuff, I would be willing to help.

Well, I wasn't able to do as much today as I thought I might. I had a DJ and a guitarist both come in today wanting a rush job on repairing their equipment, so the Galaxy had to go back on the shelf. I'm hoping I'll be done later tonight or early tomorrow, so I can get back to working on it...

Voltages are actually quite low on all stages, both tx and rx. I'll see what I can find out.

Okay, I couldn't get a lock good enough on the collector of either final. The voltage kept drifting, and I would lose trigger before the image could be saved. Here are the images with the mirror board in place. Base of driver Collector of driver Base of Q47 Base of Q47

Ignore those. I forgot to put the mirror board back in. I'll upload the correct ones in a second.

Also, this is what comes out of the antenna jack. Keep in mind it is going into a 50 Ohm load.

Okay, that helped me fix something. I had the probe set for 10x, but the scope had the probe set for 1x. After fixing it, I got some better results. Base of driver Q48 Collector of Q48 Base of Final Q46 Collector of final Q46 Base of final Q47 Collector of Q47

Okay, TP2 to center leg of both finals shows continuity and relatively no resistance. The resistors, 255 and 257, I switched out to 180 Ohm resistors as per your previous instruction, but they both are showing 8 V on one side and .45 V on the other. The rest of the resistors in that area seem...

Okay, back at the shop, and to give an idea of what I'm seeing, here is what is on the collector of Q48. Here is the base of Q48 Here is what I see at the base of Q46 Here is the base of Q47 These are all in AM, with no modulation. The only thing that is anywhere near correct is the...

Yeah, the alignment instructions say to have it on LSB, which is what I did.

There was a trace that lifted on the collector of the driver, but I repaired it with some copper foil and epoxy, and tested that the trace conducted through to R305. Otherwise, I don't see any other problems with traces.

I misspoke. It is .046 amps, or 46 mA. I don't know why I tend to drop zeros when I am doing that. I think I debate between writing it out in milliamps or amps, and combine the two by dropping the zero. Anyway, I will check all your tips when I get to the shop tomorrow. Thanks.

I do see a difference, but the signal on the collector is still so weak that it doesn't give a very good trace on the oscilloscope. It looks like stair steps. As for looking at another dual final radio, I don't have any other dual final radio to look at.

How many of those people that are off frequency when you are listening to sideband are off frequency because their clarifier is unlocked? That is very difficult to know, but considering how common a modification that is, I would bet it is quite possible. Anyway, back to repairing this monster...

Even if everyone's clarifier is unlocked, and they are running on the same frequency, when you tune your clarifier, you are essentially guessing at how someone's voice should sound, which means you might mistake the conversation as being on two different frequencies, even if they are on the same...
