First licensed in 1962, in Huntington, LI, NY as WN2CUM and later as WB2CUM where I was active DXer on 6 & 2 meter AM with a 20 watt plate modulated Neil Alpha, using a Ameco converter, and later on SSB with my Halllicrafters SX-101A and HT-32 and an HA-6 and HA-2 transverters.
I relocated to Illinois in 1966 and was issued WA9HRN. In Illinois I was an active HF DXer with a five element 20 and four element 15 meter monobanders at 98 feet.
I relocated to California in 1999 and changed my call to W6ADV. I'm in my third deed restricted neighborhood, so my antennas are limited to what cannot be seen from the street. The antenna farm curently consists of a 20/40 meter full wave CCD antenna at about 45 feet pointed N/S, a 20 meter dipole E/W, 40 dipole pointed E/W and a 17 meter dipole pointed E/W. These are selected with a remote antenna switch giving me 360 degree coverage on most bands.
Equipment in the shack is a Kenwood TS-950SDX feeding an Alpha 76CA running three 8874's.
