I just got a new Lincoln II Plus I am using as a base station. Great little radio. In the past, I owned a Uniden Bearcat 980, and used their BC906W wireless microphone on it. Very handy. Recently I saw a President Liberty wireless microphone that is obviously the same basic construction and design. But the President mic is only sold commercially in Europe, and is much more expensive for me here in the states than the Bearcat version. My radio guy told me that a Bearcat mic would fry my audio circuit. I found several diagrams online that show the mic wiring is the same from Lincoln to 980.
I sure would like to find someone with first-hand knowledge of whether the Bearcat microphones would work on the President Lincoln II Plus.
Extremely easy if you can solder. Look at the pin out for a 980. On the pin that wants the receive solder a shielded wire center and the shield to common ground. Run that cable out the mic connector with the regular mic cord. Other end of cable put a mini jack. Make sure cable is long enough to get to rear of your radio. Plug into extension speaker . Start with volume off. Put mic up half way maybe 4 beeps. Then turn up volume until it sounds good. Now control volume with mic. I make an adapter so the factory cordless mic plugs into it. It's now a 4 pin with a 9vdc wall transformer wired into it and a mini jack. I can use it on any 4 pin cobra or any other radio using 4 pin to whatever adapter. Also the mic will not key a relay radio. I mod the receiver part of the cordless mic adding a mini relay inside so it will key older relay radios such as FT 101E, TRC 458 457 etc.Anybody figure out how to add the speaker Jumper from the Base you hook up to your radio?Would like to use mine on my anytone 6666 but no RX in mic.also any mods to get more Modulation?
I did that mod. And I can say it really works.Ok thank you.Here is something you guys might like.
Looking a little further, it does appear that it requires the use of the speaker output:
