I have an interesting one. For my own reasons, I tend to run mostly realistic radios at home, eventually want to have all the base ones. Anywa, my d104, and my ast-878 work fine on other radios but on the realistic trc-433, 434, and 492 any real drive at all they squeal bad. the 878 at least I can run it as loud as a stock mic, the d104 forget it. With my dm-452, my radioshack desk power mic, my older realistic power mic hand held and cobra hand held power mic that looks almost identical to the radio shack one, I can run them as hard as I want and the radios take them all day long. Does anyone know what I can do to fix this? I've known people to run d104s on 2 of these 3 radios in the past and probably the other one as well. |

I believe you might be getting RF feedback in the room you are in. Make sure you have a ground rod outside with a cable from the radio to the ground rod. Personally I like to use the center wire of rg 213 or rg 8u with out touching the shield. What the shield then will do is keep the noise or RF contained on the center wire. Make sure you do not let the center wire touch the shield . I do this because I have to run a ground wire longer than 9 foot. I do this and I have no problem's with RF or squeal or feed back of any kind. I hope this will help. |

I'm not going to say that's not possible, in fact I'll try it but I don't understand why it would happen with the astatic mics, but so far nothing else I've put on my 3 realistic bases do that no matter how hard I run them, haven't tried the mobile with the astatic mics yet. It could well be something like that though since when I got the d104 it was already wired for realistic so someone must have tried it and I'd guess it worked unless that's why they got rid of it.. Personally though I'd keep the mic and either figure out the issue or wire it for somethign else, like one of my lesser used radios. The Johnson would be nice but I can't find the mic plug for that one to wire it to, or make an adapter which is what I'd like to do really. |
