While at Pacificon this fall I purchased a Heil Handi-Mic for my K2 #0261. I've read this list for a long time now and know about the K2's need for a mic with higher-than-normal output. Researching the Handi-Mic on-line I expected the model HM-iC (for Icom) would be the right choice. So before making the purchase I went to the Elecraft booth and asked THE MAN, Eric Schwartz, and he said that's the one to get. Well, I haven't found out for sure yet because I still need to build my KSB2 but I have no doubt that I got the right info from the right man. Don's response (below) seems to agree.
I also purchased the Heil CH-1K (Kenwood) cable to go with it, the plug matches the K2 and Eric said I can then use the default setting on the KSB2 header. It should be a nice setup. 73, Gene K6TTM > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Don Wilhelm > Sent: Monday, December 04, 2006 10:57 AM > To: Frank Van Cleef W1WCG; elecraft@mailman.qth.net > Subject: RE: [Elecraft] Heil Handi Mic > > > Frank, > > Unfortunately the Heil HC-4 and HC-5 elements have lower > output than typical > mics.
