First licensed as KN0BTD in 1950, later as Technican Class, K6LEW (1952), then General Class in 1958. Amateur Extra Class as K6LEW until March 2004, when vanity call K3CB was granted. I live in Royal Oak, MD. My fixed station and my mobile are CW-only on all HF bands while operating all modes and allocations from 50 MHz to 10 GHz from my fixed station on the DELMARVA peninsula in Talbot County, Maryland, near the town of St Michaels. My interests are experimenting, building, and operating my own equipment and antennas (having owned C3i), especially microwave and millimeter wave narrow band stuff as well as supporting, maintaining, and operating our microwave station at K8GP, my VHF Contest Group. I am a Life Member of the ARRL and the Central States VHF Society. Member also: Potomac Valley Radio Club (PVRC), DELMARVA VHF and Microwave Society (DVMS/K8GP). FISTS 14715, CWOPS 303, SKCC 6407.
See the beacons tab at the top bar for information about my microwave beacons.
My ham shack is in one of our fields (shown at "Contact Me" tab). HF equipment consists of an Orion II driving an Emtron HF amplifier using a GU78B tetrode. HF antennas are a Force 12 Delta 6BA (40M-10M, shown in the "Slideshow" tab) on a telescoping tower; a full-size 3 element, 30M beam above the Force 12; a full-size, highly-customized windom for 160M; a 167ft long Inverted "L" with its apex at 80ft, also for 160M; an OCF Dipole for 80 thru 30M; and a 1/4 wavelength Vertical for 160M. On HF, 160M cw is my main interest. Wire antennas are off the horizontal arms on my HF tower.
My day-to-day interest is VHF and up. Mostly on 6 Meters and VHF/UHF WSJT. My second Orion II drives a DEMi 6M XVTR, driving an 8877. Output is to 4, hmbrw, C7-50's (K1JX design). My tower dedicated to VHF+ is Rohn 55G using a K0XG rotating tower system. Feedlines are LDF7 to LMR600UF with LMR400UF along booms to coaxial power dividers. 4 Dow Key (HP) relays handle phasing (BIP/BOP) and antenna selection. I use my same Orion II with Demi XVTRs and KW amplifiers on 2M and 1.25M using 8877's, 70cm uses an 8938. I run Demi XVTRs on 33cm and 23cm, amplifiers are solid state: 500w on 33cm, 1kw on 23cm. The 33cm and 23cm XVRT LOs are frequency locked using DEMi A-32 pre-programmed synthesizers with 10 MHz input from a Spectrum Instruments, Inc. TM-4, GPS-disciplined OXCO. I enjoy MS and EME on 6M through 23cm using WSJT software.
Other VHF and up antennas are hmbrw: pr FO12's, pr FO16's, pr FO25's (H-frame), Directive Systems provides: pr 33cm long loopers, pr 23cm long loopers, pr 13cm long loopers, pr 9cm long loopers (all on the same H-frame), 2ft dish w/dual band feed for 5.7 and 10G is on the forward face of my microwave H-frame. I use DEMi and DB6NT xvtr's driving solid state amplifiers on 33cm thru 3cm (500w on 903, 1kw on 23cm, 25w on 13cm, 10w on 9cm thru 3 cm). The xvtr's are frequency locked using a Spectrum Instruments, Inc. TM-4, GPS-disciplined, 10 MHz standard to a DEMi "10-4", 10 MHz, amplified and filtered 4-way divider (Downeast Microwave, Inc) then to JWM Engineering Phase Locked Oscillators (JWM Engineering). 13cm thru 3cm amplifiers are DB6NT (DB6NT, Kuhne Electronic). All microwave equipment is mounted in a watertight box at the top of the VHF tower within 2-3 feet of respective antennas. My VHF tower is a rotating, Rohn 55G. Thanks for looking, 73, Owen, K3CB
