Like I said earlier, I apologize if I offended others. As far as me claiming to be a tech, I just go by what my locals call me. I have no college degree, certificate, etc... To be honest, I've seen a lot of people in society brag on their degree, college education but once they're put under the...

I apologize if I offended anyone on here, that was not my intention by any means. I'm just fed up with a couple of my locals (who are drunks) always trying to compare me to their old local tech (whom I got along with fine) who is passed away now. Their old tech (he wasn't really old in age, bout...

Got a rant!!! Ok, as many of you already are aware of, the old school techs are passing away, retiring, etc...leaving us current techs to pick up the pieces. Well, we current techs don't like being compared to old techs, many of which are not with us any longer. We current techs are fixing all...

Rock on cable, great job...

Check your Passthrough regulator and AF regulator. The Passthrough regulator is mounted on the side of the chassis, big fat transistor with three legs. The AF regulator is the smaller transistor standing up freely in front of the Passthrough regulator.

Modifications I removed: Resistor/diode combo mod removed from bottom of AF regulator over to the modulation transistor. Replaced 10k resistor (wasn't factory) in R238 location back to a 5.6k resistor. Replaced 1k resistor (not factory) in R174 location to a 5.1k resistor. Replaced 3.3k...

Final results: Receive is great in all modes. All functions work properly with no scratchiness. Transmit is great in all modes. Output before: RF power all the way down - 3w carrier RF power all the way up - 5w carrier RF power either way - 43w PEP swing, 18w average. SSB - 43w swing Note...

Thank y'all for popping in.

This one has the frequency counter module mounted vertically behind the display. I do have a Saturn that has the type you mentioned though. Turned out the 7805 regulator on the frequency counter module was shot, possibly due to these old caps. Instead of fixing that one at the moment I decided...

Got another Saturn on the desk for just an evaluation, recap and alignment. Radio works great other than receive a little low on all modes but I already know where that problem is located at. The other issue is the frequency counter doesn't display at all when powering the radio on. When I flip...

Only resources I have are a few Sam's photo facts of oddball radios (not very useful for most of the radios I work on), my old school ways, online sources and you guys/gals. I do have the PLL data book and the EEPROM data book. Plus I have the secret CB books and tune up master editions (which...

Hahaha, napalm would prolly do a better job at it than soap and water, lol...

Got a question for the pros that I hope doesn't sound like a stupid question: Why do some radios with USB/LSB have big changes in the tone of receive from USB to LSB? What would cause LSB receive and transmit tone to sound nasally (tinny) sounding, although on frequency but USB receive and...

Got an old classic on the desk again. This time we have a 40+ year old Excalibur SSB (US version, EPT 10A board) in for checkup and recap. Upon evaluation: 1. TR32 removed 2. R249 removed 3. TR53 removed 4. Regulator swing mod 5. Swing mod in empty spot beside modulation transistor in...

Now on to two old classics... Excalibur SSB (US version, EPT 10A board) and another Galaxy SSB Echo (also the EPT 10A board). I'll make separate threads on those though. Thank you again to all that jumped in with advice and detailed info. You're very much appreciated on my end.

Good grief, hahaha, all this hassle over my overlooking things, lol... Turns out it was R169 not being soldered in good. One of its leads is so close to one of the R187 leads I removed that the heat from my desoldering gun must have weakened that R169 leads connection. Anyway, I resoldered...

Noticed R169 is not soldered firmly, feels loose but joints look fine, have to dig with probe at the bottom of it to get a reading, but it does read good. Could R169 not getting soldered down firmly cause this?

These voltages are taken from the component side, not trace side of the board. This is immediately after turning the radio on and it immediately goes in to transmit mode. Only components I haven't re-installed yet is TR33 (Roger beep oscillator), C128 and TR32. These components are left out...

Haven't rechecked voltages on the 4558 again yet, but will in the morning. As for D77, it's the original KB diode.
