I run a Heil HC5 element with my K2 (#4044) and the mods I used are
simple. I changed out the capacitors on the SSB board to give me the

took to get my audio sounding great :-)

Morning Ian,
Out of curiousity, what type of mic with the Heil HC5 element do you use -
desk, hand, boom? As I told Jeff '0ff list', I have always used the Heil
Pro-Set Plus with boom mic and HC4 / HC5 elements without any modifications
to the K2/100, nor preamp, and get the full specd. output on all bands
without shouting. Power measured in 50 +j0 calibrated load with a scope,
cross-checked with a RF voltmeter. SSbA at 3 and SSbC at 2-1 with the HC5. I
have not had to use the 'DX' HC4 yet, and most QSOs are with DX on 40m.
I wonder whether a HC5 in a boom mic has something to do with it not being
necessary to make modifications to get full power output.
73,
Geoff
