Visually impressive (for us shallow people) Just two ssb QSOs so far, one rpt was pse QRP and the other was 'wow'. What I noticed first about the microphone is how heavy it is.

Once again Bob Heil has created a microphone that is a cut above the rest The PR780 was designed specifically for use with the Icom IC-7800 transceiver to produce exceptional audio. Didn't spend a lot of time optimizing yet, to busy on CW. I found a great deal on eBay for a new EV RE20 and matching shock mount. Sometimes new xcvrs are sensitive about that and try to get-even.
