    Galaxy Saturn base radio - no transmitted audio.

    Hey Andy, right, where do I start? Well, I think I have got myself into a bit of a muddle I'm sorry to report. I have done some of the things that you instructed. (bits that I haven't done yet, is because I need to source components). Just thought I'd update you with the status so far...

    Galaxy Saturn base radio - no transmitted audio.

    Hey Andy, Thanks again for taking the time to supply all this info. Forgive me if I have misunderstood, so its possible that the original Tr32 in my radio may have been something other than the 945? Which could have been more tolerant to the higher voltage present? It could be worth replacing...

    Galaxy Saturn base radio - no transmitted audio.

    Hi, apologies that its been a while. I did a little more checking today under your instruction: "Now, I need you to check D71's BANDED end - what is your voltage in TX then to RX?" 7.7v in RX 4.6v in TX "Then go to PA mode, and do this again D71 TX and RX..." 7.8v in RX 7.8 in TX D71 is good...

    Galaxy Saturn base radio - no transmitted audio.

    Hey Andy, I had a quick look this evening. Re: TR31, measured as: AM tx 0.72v tx 0.73, same for FM and 0 on LSB and USB. Sounds like TR31 is behaving? Had some trouble locating TR901 I'm afraid, so haven't looked at this yet. The mic amp IC is getting 8v at pin 8 and pin 3, just under 4.5v...

    Galaxy Saturn base radio - no transmitted audio.

    Hey Folks, I had little time look at the Galaxy Saturn this evening. Not as much as I would have liked but hey! So, this is only a small update: I removed C132, and checked to see if there was any audio. Unfortunately there was none. Checked C132 and it reads 1.081uf. TR53 is installed and...

    Galaxy Saturn base radio - no transmitted audio.

    Hey Mr Nomad, Thanks for the info. I tried moving the SSB ALC pot to its extremes, neither setting made any difference I'm afraid. I checked the voltages on T32 and compaired them to the service manual. In AM RX the emitter was zero, the collector was zero and the base was just a little under...

    Galaxy Saturn base radio - no transmitted audio.

    Galaxy Saturn base radio - no transmitted audio. I have a Galaxy Saturn which I discovered that the AM limiter had been removed before i brought it. It also drifted terribly so I haven't used it a great deal. I decided that it should be pretty straight forward to source a replacement...
