K3 + preamp for CQ VHF Contest

Edward R Cole
Mine is not a PR6 but equivalent in NF and gain specs.  I
re-installed it after replacing the GasFet (mgf-1402) which somehow
bit the dust awhile ago.  It is installed on the K3 RX IN/OUT same as
one does the PR6.

I measured increase of my K3 6m MDS from -136 to -145 dBm using my
XG3 and 30-dB attenuator.   Worked very nice for the VHF contest this
weekend.  I now have one of my 3-element 6m yagis end-mounted on one
leg of my tower at 22-feet and fixed in the direction of the US west
coast (120-deg.) from Alaska.  I worked six stations in five grids in
the Pac NW on Saturday night in a two-hour opening.

I will have some new photos tomorrow on:
