Thank you for visiting my QRZ page. That is me on the right in the photo, along with my son KE8BHE. I provide QSL's for all HF QSO's. Please look for yours here on QRZ, and on eQSL and LoTW. I enjoy receiving printed QSL cards by mail or bureau too, and will reply with mine in all cases. SWL and VHF/UHF QSL requests are also welcome.

I've been a licensed amateur since 1972 thanks to initial help and encouragement provided by generous parents and members of the Johnson County Radio Amateurs Club in Kansas City. Orlan W0OYH was my "Elmer" there. Activity has been sporadic since then with more frequent operation starting in 2012. I operate on all U.S. HF bands except for 160m and 60m using CW, JT65, JT9, RTTY, and SSB.

Main station: Icom IC-718 with Collins CW filter, Alinco DM-330MV power supply, SignaLink-USB, homebrew 6-pole CW audio filter (on left of Icom), and homemade pi-section antenna tuner.



I occassionally operate my 1970's Novice station consisting of five Heathkits (the four green enclosures and one gray one - a HW-16 "trans-receiver", HG-10 VFO, HS-24 mobile speaker, HD-10 keyer, and an AM-2 SWR bridge), a 2000-Ohm Acme/Trimm headset, and a plug-in crystal assortment. Newer items on the right include a homemade marker generator constructed from plans found in the ARRL Handbook and a WWV receiver.




Other interests include motorcycle and bicycle riding and maintenance, fitness activities, home and car repairs, kayaking, and occasional hiking and camping trips. I am employed as an electro-optical engineer.


Antenna information:

Antennas include an outdoor OCF dipole that is used on 80m, 40m, 20m, 17m, 12m, and 10m, and three attic units - a 10m dipole, and two parallel-fed dipole pairs for 20m/40m and 15m/30m. The 20m/40m setup is also used in 3rd-harmonic mode for15m.

The OCF dipole is oriented 67 degrees E of N, while all of the attic dipoles are at 120 degrees E of N. Height of the OCF antenna ranges from about 20' to 30' over local terrain. The attic dipoles are roughly19' above a steel-reinforced concrete slab foundation.

The OCF dipole employs a short run of RG-58 to a homebrew 4:1 dual-core balun that is followed by a longer run of 300-ohm twin-lead that terminates at the dipole.The attic dipole pairs are fed with a single low-loss RG-8 cable terminated with a homemade "ugly balun" choke and an A/B relay box at the feed point. Estimated worst-case feedline loss for all antennas is -2.3dB which occurs on both 12m and 17m.

The tuner shown above is typically only needed with the OCF dipole on 17m and 80m. This is thought to be due to unfavorable alignment and spacing between the antenna and its twin-lead feedline.

I log signal power at the transmitter output for CW, RTTY, and SSB QSO's, and corrected power after system losses when working JT65, JT9, and PSK31.
