Very good info guys. To do this really perfect we need so many equipment and we don't have that. So I think with the knowledge and tools we have we are doing quiet well in having the Galaxy alive again. It's really a drama to get parts here in Europe. I don't know if thats the same in USA I...

OH now I am somewhat confused guys. The specs are 10 Watt AM/FM and 21 Watt SSB for this Galaxy Saturn. And my measures are 10-12 Watt AM/FM and around 20 Watt SSB. Even when I switch my SX-200 watt meter to PEP I never see more Watts then 20. The only difference I see is that the wattage stays...

Thx I repaired the Galaxy and in the mean time learned a lot extra. I noticed that decades ago when I did this with much less knowledge the puzzles are now coming together. Another question just raised I hope I can explain it in reasonable English. I learned about PEP power and I do have a PEP...

oke today I changed VR10 and VR20 and the MA measurement is much more stable. I do see change between cold and 15 inute safter and I see direct change in holding the key. Like it starts on 95MA and goes linear to say 110 MA. I now have 12 Watt AM/FM and 15-21 Watt SSB it depends on what band. I...

New findings in the category EUREKA! The no mic audio was indeed the Mic Gain potentiometer. I did test that guy earlier quick and dirty, but when I de-soldered it, it was clearly faulty (Mega-ohms) thx Dr.Frankenstein for drawing me back to the basics. Ok so we have power and mic audio! The...

Ah this is so wonderful thx. What do you mean with a map? Like a diagram? Yes when its not too much trouble because my solder level is 5.5 I can use all the help.

Very very good info guys! I am one Big step further! I will explain. Fist I want to say too loosecannon, you are totally right. And it's very difficult to determine what person is on the other side of the chat. I can only say I do this hobby for about 50 years now and have some experience. But...

Sorry, no the mic audio is gone on every mode also AM

Ok clear thx. I must say again that theoretically I am not capable enough to do those repairs but in all those decades I did have my eureka moments and I hope we can have one of those again. The bad thing is that I have to approach this one through the symptoms side. Also where I leave is...

Yes correct I don't want to make it worse, but in those complicated cases some tests can make a direction to search again. Because it was all good when I stopped a few years ago and now it starts with 2 serious symptoms, I think both issues have the same root cause. I just tested the PA and...

What do you think is it safe for testing purposes only to make a bridge between DC ground and chassis ground? Just to see if the microphone plug has good ground.

I did a measurement of pin3 of the microphone plug today and I am not sure if this is correct. I read between pin 3 and the chassis ground and the voltage is starting with 10 volt and dropping to around 3. Is it correct that the chassis ground is not connected to the DC ground? When I measure...

Thanks for your response and link to the data! I do have some schematics but the thing is that I find it very difficult to determine where to start when you look at my specific symptoms and measurements. What do you think where to start in this case?

well, this can be a start of a too big adventure but lets try. I have a Galaxy Saturn for decades now and after a few years I fired it up again just to see some problems from the very start I started the TX. The first days I only did some RX listening. I am almost sure it was good when I putt in...
