Turner plus 3 mic problem

[SCOTT 821]

Hello there, I have an old early 80's sears roadtalker model 663, I also have a Turner plus 3 mic, but here's the problem. When I transmit on sideband, the rf meter goes all the way over and then the radio dies out without me even speaking. The mic seems to work on am just fine though. Another thing I noticed is the tx lamp goes yellow instead of red, I think it's like a caution lamp. To make shure the mic even worked, I tried using the PA system and I had everything hooked up okay, but I wouldn't come over the speaker. I do think the mic works, because when I adjust the gain the rf meter moves a bit from the dead key position on am. I've tried having the gain down but it still don't work. I know the mic does work on SSB, because I've seen online that people have used on SSB. This is a great mic from reviews online, and I would really like to have it working.I think my problem is that the mic is putting too much power or over modulated for the radio. If you have any idea as to how I could get this to work, feedback would be appreciated. Thanks, and 73s

The 'yellow' LED doesn't mean 'caution'. But in another sense - it does. Looks like it is trying to transmit and receive at the same time. Either you have improperly wired the mic to the radio; or there is a problem with the SSB transistor switch. I'm inclined to think it is the latter, so you would probably be better off to send your radio in for repair. If you have the stock mic; then try that first.

if it works fine on AM and PA it's not a mic problem, it's a radio issue.

Hi there! I appreciate your replies. The radio does work fine with the original stock mic. I'm just trying to get this turner to work with the sears because it's better thab my stock mic. The sears takes a 5 prong din mic. When the turner outputs the standard 4 prong, so I bought a converter for it that fits in the radio fine. From what it sounds like, the coverter may be putting the wrong wires to the holes in the mic socket. Thanks again for your feedback and 73s

 

[SCOTT 821]

OH! forgot to mention the stock mic does work on the PA system

Then the wiring of the Turner mic is wrong; don't use it on the radio until you straighten that out.

 

[SCOTT 821]

K will do! thanks for all your help goodnight and 73's too ya once again!

One thing that I would like to add here is that the light is only yellow when I transmit. the green rx lamp seems to be fine when I'm recieving. I'm adding this in case you thought the reason why it was doing both was because of a constant yellow lamp. Nope, only when I transmit. Thought I might wanna clear that up just in case!

I don't see how the wiring can be wrong if it keys up and modulates on AM on the same radio that is having the ssb problem.

Turn the gain all the way down on the mic, switch to ssb and key up. The meter should not move if it does there is something wrong with the radio , mic or adapter. If the meter does not move then turn the gain up till it does then back it down slightly. You might be getting feedback.

 

[SCOTT 821]

Yeah, feedback may be a problem. I noticed when I tested the PA that even though my voice wouldn't wouldn't come over the mic would squeal when when I keyed it with the gain up a bit. Like I said though, I still have the problem even with the gain down and the amp battery out (the mic has a voice amp).

 

[SCOTT 821]

Also, the mic does modulate without me even talking on SSB and rf meter goes all the way over with a little hum sound and the radio dies out. I don't think it's the radio though because it's fine with the stock mic to answer w9cll.

I use a +2 with a Cobra 140 GTL it doesn't like anything over 3 an I get feed back ( on SSB ) Am I don't have any problems you can dial it up .Ps when I say 3 that's pushing the envelope !

I take it you're using it as a base station? thats what I'm doing with my roadtalker 40. It's a mobile, but I have an old robyn SX - 12 power converter base module. So it seems your + 2 works fine huh? do you have to use a prong converter for your mic? I was thinking the mic pinout converter I'm using may be my problem but probably not.

If your stock mic works correctly and the Turner mic isn't working right; then the problem is probably your converter plug. Not all converter plugs work with all radios - just because it uses the same pin arrangement. Not all RoadTalkers are built by the same mfr - either!
