OK,
I have my Ar-3500 as many of you know.
I tryed hooking it up to my mickey moused power supply in the house (optima yellow top/ trickle charger) and both transmit and recieve have a nasty hum. My first thought would be power supplu, but even running off the battery directly with out the charger it's still there! Other radios don't do it!
Any ideas?

It does not know the words?  Are you grounding with the home bond at all? |

Just a thought...as old as those radios are, would a dry electrolytic capacitor in the power-filtering or audio sections cause your hum?... |

my suggestion is to send it here, PO box.....
oh, i guess you want to KEEP it. sent ya a couple suggestions, bc. since it's in BOTH rcv & xmit, gotta try to see if ANYTHING alters tone or intensity-mic gain, power output, external speaker, disconnect stock speaker, change of mic/no mic, loose board connections-any of the boards, CPU connections, that little beep that happens when you press the buttons, etc.... |

i can remember running the same setup years ago.
i ended up just putting a capacitor between the pos. and neg. leads.
problem is that it was so long ago i don't remember what size cap. i used |

OK Here's the deal.
It stopped!
Just up and stopped!
No changes, I turned it on to start illiminating possibilities and start the fixin' and it stopped!
Oh well.
You know I had a VW once that did stuff like that, would work one second, not the next, then work again! Would never be able to find the problem(S)

It was probably moisture in the distributor - fairly common problem with air cooled VWs. |

About half way through your post, Hollowpoint I thought you were talking about the radio
