Anyone out there seen or have experience with these for use at Mission Base?

After a google search, I can't seem to find any base style headsets anywhere for any EF Johnson radio.

My DC has built some nice home-grown ones, haven't seen anything for the mobiles, just for the HT's.

I think that anything for the Motorola HT-1000 handhelds will work, but I haven't seen anything for the base station. 

In a "congested" and busy environment it would be nice to allow the operator to shut everyone else out.

As long as we're on headsets, does anybody know of a speaker/mic headset for the Micom-2?  I share our comm room as an office with my PAO, and the HF static is driving her nuts when I do my nightly check ins.  I know the serial number for the headphones is TRN6273, but I can't find a picture and I think its just headphones for use with a CW key.

Actually, it lists the 5100, which is the portable/handheld, not the 5300, which is the mobile.

I've been experimenting on my own 5100 portables and 5300 mobiles using the aviation style david clarke headsets.  So far, so good.  I had to order connectors for the mobile and it worked well.  There is bias voltage and speaker audio available at the connector. 

I just got an adapter for the HT in the mail and have not had too much time to play.  It's pretty straight forward and I am planning on using the PTT switch on the adapter (although I could use a pickle switch). 

Once I get the HT adapter wired, it should work for my motorola public safety radios as well.

The mobile audio was just fine (microphone) and I used a jack to allow a pickle PTT switch or a floor switch.  I'm still deciding on how to mute the mobile audio (for stealth mode).  Not sure I want to or not.  The headset is a great way to go for a comm room/eoc environment.

I've also wired a couple of motorola base microphones for the mobile -- makes it nice for an EOC comm room.  I've also added (with the base mic) the ability for a foot PTT switch.

Put an on-off switch in the internal speaker line in the Aux plug out the back of the radio?
