Siltronix 1011c & Turner mic

[NITROTURBO4U]

Is this a good combo???? Just aquired the siltronix.No mic
Anyone know mic wire setup for this????
It is the turner super sidekick with big chrome top..
Thanks a bunch.

Hello Nitroturbo4U: Wow that's another older radio, but they played pretty well in its day.

Here is the CB Tricks info on the Silly 1011C:
Siltronix Model 1011C

I would think the Turner SK Mic would work ok on the rig. The diagram shows a 1/4 inch stereo plug for the mic on the diagram. Shield goes to the body of the connector, the audio / mic wire goes to the first inner ring, the PTT that switches ground for the PTT function is wired to the end ring of the connector.

These rigs had a reputation for drifting a little so let it warm up a few minutes.

Good Luck, let us know how you made out with it. I have a General Radiotelephone SB72, that is a old 1963 CB, SSB & AM radio, that I would like to get going.

Should be fine. All of those old Turner amplified mic models work great with just about everything. I run a Turner +3 on all of my tube CB rigs.

Be VERY careful operating that 1011C. They are dangerous rigs with extreme high voltage levels in the transmit circuit. More than one person has had a "near death" experience after getting "stung" by one of them. I keep mine around mostly as a conversation piece and it just looks flat out "cool" on the shelf... but I'd never use it on a routine basis.

Rather than starting a new thread I may as well use this one since it's on the same subject.

I've got a working Siltronix 1011D and I'm having a difficulty figure out the microphone wiring. Evidently someone has put a non-stock wire on this non amplified D-104.

There are only three wires so I should be able to figure this out right? I'm not too sure about that, My non amplified D-104 has a shield, Black and White wire. I connected the shield to the common ground terminal on the microphone. I connected the Black to the tip and the White to the middle. When I plug it in it will modulate on sideband but it cut out the receive audio. I reversed the Black and White wires and it does the same thing. What am I doing wrong?


The link below shows the wiring layout in the bottom of the microphone.

Hello comoman: See:

http://www.cbtricks.com/radios/siltronix/model_1011d/graphics/siltronix_1011d_om_sch.jpg

J1401 Mic Plug is in the lower RH Corner of the diagram. Suggest you get the Mic's wiring diagram and go from there. The Mic connector a 3 terminal 1/4 Stereo Plug, the Mic shield and PTT ground go to the shell or body of the connector, White if that's the inside of the shield wire, goes to the middle, and the PTT key wire to the end or tip of the connector. Good luck.

So in other words the cord should be 3 wires and a shield correct? The microphone cord that's on the microphone now only has 2 wires and a shield. Looks like I need to put a new cord on it.

Hello Comoman: What you need to do is verify continuity between the shield wire and black wire.

It should be open or no resistance between the shield and black wire, and have continuity when the Mic PTT switch or key is pressed. This will allow the PTT relay to operate. The Mic wire, inside the shield wire will be the audio input to the middle connection.

Also the Bandswitch appears to be full clockwise to allow the PTT ground to reach the PTT relay. the relay should be able to be heard when the PTT Mic switch is pressed. Good luck,

With the sleeve is off of the 1/4" plug the shield and the black as well as the white wire has continuity with the shield (no resistance). That's what has be puzzled. I had the band selector full clockwise when I did the test. It modulates great but is still cutting out the receive audio when I plug the microphone in. I've made sure there are no wires touching but the continuity with the shield and both wire is a bit confusing. This even continuity between the white and the black wire on the plug.

I think the Astatic D-104 DuKane 7C40 microphone base is wired wrong. I just don't know what to do to get it right.

Hello Comoman: Ok sorry I am out of things to check. But the Mic showing continuity from the shield and black wire, will mean the radio will key up in transmit when the mic is plugged in. You should only have continuity between the shield and black wire is when the Mic PTT Switch is keyed.

I just realized I high jacked a thread about Tuner microphones not D-104's. Sorry about that.

Not a bad hijack really. I had a D104 Black Beauty on my 1011D and it really wasn't impressive in the opinion of those hearing me. I traded for a Turner +3B and it was night and day. Fantastic match was all I heard after that. I miss that mic. And that radio. And my GE Superbase.

I was able to wire an amplified D104 to the Siltronix 1011D. Everyone I talked to on 38 LSB said it sounded great. I just finished reading a few recommendations for microphone for that radio and it said that an amplified microphone of any kind would not work well because of the high impendence requirement of the Siltronix 101D. I don't understand all of that but if it works and sounds good I guess that's all that matters.
