I have an Icom 706MkIIG. The standard mic is really simple, a PTT switch and an "Up/Down" frequency button and that's it!
Well I've been surfing the net this evening to see what's out there for a DTMF mic for this radio. It looks like an Icom HM-154T or a HM-118TM are the ones to get.
The thing that has me a little confused is that the HM-154T and the HM-118TM are also options for the Icom 2200 so it would seem that the DTMF mic (HM-133V) that comes standard with the Icom 2200 should also work on the 706?!? The way I look at it the mic needs to send the signals and get the power in the same way, regardless of what radio it's connected to. Does that make sense or am I confused? Has anyone tried this, or is anyone willing to give this a try?
If it does work I'd be tempted to get an Icom 2200 for the wife's truck (she doesn't have a licence but I do drive her truck occasionally) and use the mic for my 706! The list price for the DTMF mic is nearly 1/2 the cost of the entire 2200 with the DTMF mic included!!
If you folks are willing to watch for a mic I'd be grateful! Paypal is waiting!
