Can ICOM IC-7000 microphone be used with Xiegu G90?

 Yes, it can be use!

As a matter of fact, any RJ-45 ICOM microphone can be used with Xiegu G90 transceiver.

Of course, the ICOM remote microphone is using a different serial protocol to communicate with the radio so the function buttons WILL NOT work.

Basic PTT and modulation WILL work. 

I also tried with the microphone from other radio, from ic-703 and IT DOES WORK.

This is the proof, in a small video I made this evening after a fellow ham said on FB his combination is not working.

Here are some comments about the Xiegu G90 RJ45 microphone pinout:

ATTENTION!!!!

The RJ45 is the female connector as seen when you look to the front panel!

MDATA - This is the serial Data from Microphone to Front Panel Unit. Pretty similar to CAT protocol but with some differences. It is not ICOM Compatible but the voltage level is the same.

GND - Ground. Not Shield.

MIC - Audio signal from microphone to radio (HOT signal).

MICE - Microphone ground, the shield of the microphone signal wire.

PTT - PTT Switch, goes to Ground to switch the radio into TX.

MSVSW - This is a pin used on ICOM radios to identify the microphone type. Not used in Xiegu G90.

NC - Not Connected

8V - 8V from the 9V LDO. Actually, around 8.7V on the G90.

Thank you!

Silently, my blog got over half Million visitors since I began counting and over 1 Million views since the first post, 10 years ago.

WOW!

To all of you, Thank you for the visit and I hope you got something helpful and interesting here.

QCX CW

 YO3HEX, Dexter gave me a nice present! 

A QCX CW pocket transceiver. 

It is able to put around 4-5W into one band and it is working only CW.

It was an awesome project for an afternoon and, after some 4-5 hours, the radio was ready, tested, the fine tuning made and on the second day I already made two CW contacts!

Here are some pictures from my work:

An eagel eye will notice the OpAmp misplaced (the right-side one).

One ferrite toroid snaps. Broke in three parts. Fortunately, I got a lot o this Type 2 toroids. Unfortunately, they are at my second lab, too far away for a lazy ham like me...

This is why I used ol' SuperGlue..

The project is completed. The OpAmp, still upside down.

 

Powered the TRX, current surged to around 1.5 Amps. Fortunately, I start all my experiments on my special design lab power source so no irreversible damage occured.

I found the fault pretty easy, the area was warm. I took out the OpAmp, put instead a 2x4 socket to check if the original circuit survived. 

I took the time to change the LCD with a Yellow-Green one and the original contrast trimpot with a 10KOhm one for a better range of contrast.

After I put the circuit on the right position, there was no damage so I took out the socket and placed the OpAmp directly on the PCB.

The broken toroid is doing well after SuperGlue surgery! 4W at 12V, this is nice.

Thanks to Mihai, YO3ISL, the radio got a nice case!
