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 call changed to WA9HRN. In Illinois I was an active HF DXer with a five element 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, a 20 meter full wave CCD pointed NE, and a 20/40 trap dipole pointed E. These are selected with a remote antenna switch giving me a 360 degree coverage.

Equipment in the shack is a Kenwood TS-950SDX feeding a Collins 30L-1.  I also have an Alpha 76PA running three 8874's.

My current passion is collecting spark era radios, keys and components.

The photo above shows one of my four working Spark Gap stations. (Click to enlarge)

This is a 1/2 KW Rotary Spark Gap with a 10,000 volt adjustable Thoradson transformer, Murdock oscillation coil,Murdock rotary gap driven by a Holtzer-Cabot motor, Murdock glass plate condenser, Murdock antenna switch, Smith Roller hot wire ammeter and a Sprague anti-spark back keying condenser, mounted on a Signal Electric spark key.
