Based on continued constructive user feedback, we are officially announcing that all of the FLEX-6600 and the FLEX-6400 Signature Series SDRs, including the "M" models, will ship with a FlexRadio FHM-2 condenser hand mic. The mic will connect to the back of the radio, using the 1/8' mic connector for audio and the RCA PTT connector for keying the radio. The mic cable will be long enough to allow for convenient operation with the radio on a desktop. We will be updating the New Product FAQ shortly to reflect this change. Thank you for your continued positive feedback.
