Before I bought myself a Mic Tester () I used a set of wires with crocodile clips (clickable image below).

Clip one lead to each color out of the Mic, then have a mic plug with open wires on it plugged into an old CB Radio. Usually it is easy to identfy the Mic's Earth/Common/Braid so that can be connected, then just go through the other wires looking for a Make/Break-on-PTT which will identify the TX and RX wires. Then it is just a guess which of the remaining one or two wires is the Mic Audio Feed. October 2012, 22:00.

Deleted User hi did you not get a manual with the mic? As the jcd201m mics i sell all have a manual and has the hook up details in it for the pins on the sockets on the back of the mic.in our case the plugs are 8 pin (on the back of the mic).i have no idea why they would change the wiring of that plug.there is a model that has the receive wire so it will work on early cb radios that required a receive wire maybe you are referring to this model?

California MANDATORY_FirstName Curtis Thanks for your input Mike.When i got this mic i looked at the manual and it did tell me what wires did what.The problem started when i looked for the 4 pin diagram to a galaxy 949.

Deleted User hi this is for the jcd201m to galaxy 949 using the stock jcd201 mic lead and color coding ok it does not actually matter which wire is what color.but to save rewiring the whole lead just cut back the jcd lead and reconnect the brown wire to pin 2 things to remember here are this.the shield MUST be on the audio earth pin on any radio.the wire that has the shield wrapped around it MUST be the audio wire on any radio.any other wire can do any other job.ie the pink wire can be the up.down.rx.wire. Ok that said here we go disregard what color is what in the stuff you see on line.each 'tech' have their preference to what wire to use for what function.ie.not every red wire i is the tx wire in every mic(talking about stock from the factory mic wiring here).in some cases it can be the shielded audio wire that is red.in some mics i have seen it as the up wire or the dc voltage wire. The thing that must stay standard is the shield connects to the audio earth and the shielded wire is the audio wire (if not then there will be rf feedback/hum issues.) ok down to the nuts and bolts of your problem wire as below the only things that matter to you is that tx is connected to tx(pin 4 of 8 pin to pin 3 of 4 pin). Audio is connected to audio (pin 2 of 8 pin to pin 2 of 4 pin) AUDIO earth (shield ) is connected to earth (pin 1 of 8 pin to pin 1 of 4 pin).

PTT earth pin 3 of 8 pin is connected to pin 1 of 4 pin you will notice that both the shield (pin 1 of 8 pin (gray/grey) and the white wire (pin 3 of 8 pin )are both connected to pin 1 of the 4 pin plug.that is because in that chassis radio the ptt and audio earth are shared on the same pin. All the spare wires just tape them off in side the 4 pin plug as a side note the jcd201m mic it does go though battery's if not using the self power option from the rig (in your case there is no power feed on the galaxy plug) so remember to turn the mic off each night!

If the time out timer (TOT) annoys you pm me and i will send you the mod to disable it (a wire link in the mic). I never used the variable gain on the mic i just used the low setting on the comp switch which was more than enough gain for most radios i used it on.icom.yaesu.optima.super jopix sj3000b.etc etc on the high setting it was very very loud.too loud.also for ssb /am work use the ssb setting on the pwr off/fm/ssb tone switch mike sent via my morse key and a door buzzer Wednesday, 3.

Deleted User hi i had a play yesterday with a jcd cable wiring up one for a optima.the white wire is the shielded audio wire (no guarantees that yours will be the white wire).the thick black wire is actually the shield (has heat shrink on it).in answer to your question re the colors.to make it easier to i.d which wire is which purely that.cant have 7 white wires and shield in a 8 core lead can we!

Radio - 2970dx After all said and done, both stations agreed that the mic was not very strong in the audio department. They have both said that the same radio with the 575 and Turner +3 was double the audio than what the 201M was doing. The mic was only tested on SSB.

The mic preformed the best in only one setting and that setting was: Mic was set; FM mode, Low compression. It didn't work good in manual mode when using the mic gain on the base - although it would drive the radio well, it just didn't have any 'punch'. On thing to note here that I didn't care for was, when running in Low Compression mode, the output of the radio dropped 20 watts! The same 20 watt lose when moving to High Compression.

It never sounded good with the switch set in the SSB mode. My next test will be using the 2950dx. I will be curious to see what the output will be with this radio.

I am done testing the 201 now and the mic was turned back to the owner. From talking with several people today in Calif, including Robb here from the forum, here is how it sounded. All testing was done on SSB with 2970dx The majority have voted for the mic to be set in the FM mode for talking on SSB. When the mic was set in SSB mode the audio was not as good as FM setting. It was also tested in the Low/High compression setting and it was a no go for these settings. No one like the way it sounded and besides that, there was a drop of about 25-30 watts when in this setting on the mic. Although the audio was decent, it did lack the 'punch' that the 575 or Tuner +3 gave.

The +3 actually had more drive in putting out the watts. The owner of the mic also listened to it and has decided to return it for a refund.

This mic may work on many other radio's, but on the 2970dx, like the owner has, it's not what he wants. He has listen to my +3 on the same radio and liked it much better than the 201. I traded a cobra 148 for a jcd201 mic a few years back.

I spoke to the dealer in KY that was pushing these big time way back when. I was directed to their mouthpiece.

The Connection Program Copyright. All i can say is THANK GOODNESS FOR E BAY!!!! He supposedly had a hand in the design & building of these. I'm guessing he picked the color.

Pryme doesn't support the jcd201, but. Yeah, i pretty much got the same results. I tried it on an ic735, ic751a, ic765, ft101e, ft767, ts440, a host of uniden grants, cobra 2000, and even a couple connex 4800/rci6900-type exports. On the hf rigs, it 'worked', but nothing at all to distinguish itself from the stock mic. On the CB's & exports-YUP.

Well, it was clean & clear, but absolutely NOTHING! No punch, it wasn't loud, and yes, the compressor made a difference in PEP watts, but, 75 to 90 ain't doing NOTHING. 75 LOUD watts seemed to outdo 90 'quiet' watts everytime. Looks nice, but it's missing something.
