I have the FTM-100d and would like a desk mic? Any directly compatible?
I have the same question. Can you use the MD-100ax8 desk mike with Yaesu vhf/uhf mobiles?
Compatible mics should br listed in the manual....
That being said, you should be able to see what other radios use the same model mic on that UK mic wiring website (dont have the link offhand), and see what desk mic was also offered for other radio models that use the same hand mic
Doing a quick search, (Damn my eyes), that radio uses the same mic as the
MH-48A6JA which is the same as the MH-48A6J.except that the A model has some additional printing to make it easier for APRS use.
Maybe this will interest you
YAESU MD 100A8X or
YAESU MD 200A8X
I think may work, and you would be able to use the scan on the radio...thats the big issue.
The md100/200 mics use a 8 pin connector and requires 5volts ......
The radio uses a 6 pin connector and supplies 8 volts.
not plug and play. you would need to make your own mic cord and address the voltage issue....
The MD100/200 desk mic will NOT work on ANY of the "newer" Yaesu mobile radios due to the impedance mismatch. The newer mobiles are typically 2.2K ohm electret and the Md100 mic is a dynamic 600 ohm. Yaesu sells the mek-2 8-pin round to modular adapter yet offers no plug-n-play desk mic for their mainstream mobiles??? Yet they indicate that the adapter will allow a variety of mics to be used. I am having the same issues regarding my ftm400dxr. Great radio and I love Fusion but could ya just make a complementary desk mic already!
Nearly all desk mics for modern communications gear are 600 dynamic mics. You can get a switchable impedance desk mic (and I haven't tried that yet) but you'd likely have to "eat" the mic cartridge to get any output from it! So where are these mystery mics Yaesu?? This leaves only one viable option of using an amplified desk mic to compensate for the impedance mismatch etc. That will work if the mic is adjusted properly, it's absolutely silly ~ a three stooges approach to a TX audio problem, nonetheless it'll work! An interesting observation of the mek-2 is that they mislabel pin 4 as ground, it's NOT ground ~ i.e. not connected to negative DC supply/chassis. Pin 4 is a control line "common" but it is isolated from chassis ground.
The shear irony is that a .99 cent electret cartridge will actually sound incredible on those 2.2k impedance radios! So I guess if you can fabricate a shell/stick to mount it on, you have yourself a desk mic .
First, get yourself a Heil Sound AD‑100 Mic Adapter for Yaesu 6‑Pin, Heil Sound Microphone Adapter Cables CC-1-Y, and a Heil Sound Foot Switch FS-3. Then get a nice Heil PR20 mic.
The PR20 is a 600 ohm balanced dynamic mic, it will not work on the FTM100DR (as with most newer Yaesu mobiles). You'd need a preamp between the mic and the radio. Its perty but it wont work!
Oops, sorry, I thought the OP had an FT100D. I hate Yaesu's naming conventions lately..... The modern Yaesu VHF rigs have ~2000 ohm specs for the mic input, so the mic and adapters I recommended will not work. It's too bad, because I've got a couple modern VHF/UHF Yaesu rigs that I was going to use my Heil with. Good thing I ran across this thread or else I'd be eating my Heil... I cannot believe that the newer rigs still want 2k ohms...! Why not make it a standard 600 ohm? Then again, that's like asking manufacturers to make a standard mic jack... like that will ever happen!
I do see that some of the other manufacturers like Kenwood use the standard 600 ohm mic impedance for their VHF rigs... which is quite interesting.
FTW, most of my traffic nets are on 2m/70cm.... so my FT-857D has the Heil PR28 on it... and boy the compliments I get... 100X different than with a stock mic. You'd think with FM you'd want the cleanliest possible sound too. I do notice that at least the new FT891 and the FT991/A accept the 600 ohm mics --- which is great!
I feel bad my little Yaesu VHF/UHF rigs now that I think about it.
