Uh! Asap was meaning three years .

not sure even if Rick Is still active on this forum.
I've checked those components are on it's right place.

Ok. I will do and let you know asap.

Rick: I think I understood 100% all of your post. I just called "mod" instead "proccedure" or "check" (sorry but my english still needs to be improved as you see :). When done, switching the filter to ANL+NB or ANL only position, audio changed to worse same way than bef...

Rick: I did that mod with no success. * When removing C117, audio remains as before, but receiver gain decreases a little bit. * When removing C125, nothing appears to happen. I tried to switch the NB ANL on with this mod, and audio became more distorted and low as before. I've checked again that If...

THanks for your opinions: I've just fixed a SS 360 FM (H6 version, the one selled with TONE and CH9 freq shifters and SWR Cal acting as Power knob) which had the polarity protection diode shorted (a reversed polarity in a car , you know). I didn't mattered what version was, but I afair it was PC010....

Check done. All seems to be OK: R103: On BRA side: 8.6 V aprox (as your schem says) On the other side: a very small amount of negative voltage (with a magnetic needle voltimeter, just a small negative movement). R111: On BRA side: 8.6 V On the other side: 2.1 V When switching from FM to AM, voltage ...

Hello. Just wondering if someone can drop me some light. I always wanted to find a Super Star 360 FM first series (Yes, the FM, not the previous AM SSB model), the one with a funny Roger Beep (like a bird), shorter than the later versions (but not as much short as 120 FM model). Does anybody know wh...

I've checked that components. Diodes and capacitors are ok (no shorts, no break circuit). Even the capacitors were replaced a year ago. Btw, an useful info (maybe): If I turn on the rig in AM or SSB mode, when I select AM again audio is quite good (But not OK). If I switch to FM and back to AM, audi...

Yes, It is a PTMB121D4X (really sorry I forgot posting the board number!!). I will check that diodes/capacitors.

Trim, I've tried to adjust AGC with no success. (really I didn't feel any change).

I will keep you updated. Thanks Rick and trim.

Hi there. As I talked with Rick a couple of weeks ago, I will post here what are happening to my Ham Concorde II (I guess it is the last fix I need to do). I have a distorted audio output when receiving in AM mode. I've checked it becomes less distorted if I decrease the RF gain (but still not fine)...

Thanks frog.!
I've been messing up with cb's so many years, that I am happy to have discovered this site.

It seems like your car computer box is causing interferences in your radio. I experience the same with my VHF walkie when I connect the external ant.

My CB gear: Past: Stag 357 (same as Electrónica 360, Palomar SSB120 or Fisher F140 but brown!) Ham International Viking II Present: Formac 240 (cybernet pcb) Major M788 (broken, same as Ham Multimode 3 with less switches) Super Star 3900 first series Fisher F140 (broken) Ham International Concorde I...

Hi Angus.:

I have one of these, manufactured by Sadelta. I bought it back in the 80's for doing some mods regarding echo delay, etc..

I found it a month ago, still works, if you are interested I could sell it. I don't use it anymore.

Let me know, ..

Jose.

Hi again. Thanks for answering. Sure your work is useful to many people as there aren't enough tech info regarding that models. My Multi3 problems started 22 years ago with the Roger beep U9 film fault (there was no TX delay but beep oscillator did work, so the beep came out thru the speaker breakin...

Hi there. This is Jose from Spain. Just signed up for saying hello to everybody, and specially for giving thanks to Rick. After more than a year researching, I've found rick's technical info a couple of days ago regarding a problem I was experiencing in my Ham International Concorde II (PTBM121D4X b...
