The Icom HM-154T is one rugged DTMF microphone. It's audio is pretty decent.
It can be improved though. Simply, if you want more audio drive and more
bottom and top end so that you can tailor your audio the way you like it,
send your 154T to me.
Price is the same $43.00 + $12 return shipping. ($55 total)
Personal check is fine - no delays. Postal money order is even better.
