KK5R -- Former calls: WB4DPG, WB5QGI OMISS # 6452 NOTE: For QSL mailings, please use PO Box only as follows: BOB LUNSFORD — KK5R General Background: Started studying electronics in 1955 Lived in Brazil and Peru (son of a missionary on the Amazon) and also in Panama for about six months. Attended three Morse code schools in Brazil and one in Peru. Returned to USA in December, 1961 and joined US Army in 1962 as a Morse Intercept Operator, attaining 28WPM. However, was soon transferred to a language pool to be a Portuguese and Spanish translator/interpreter for remaining time of 3-year Army duty. Still fluent in Spanish and Portuguese and can get lost and found again in French. Retired from the US Government after 31 years of service. Last duty was as a Telecommunications Specialist for the Television-Audio Support Activity (T-ASA) in Sacramento but that organization has since relocated to Southern California. Some Places Worked: IBM Engineering Development Laboratory, Office Products Division After retirement, I went in China to teach English for four years but I'm now back in Kentucky, at least for a while. Still have hopes of either going back to China to teach or moving to Texas, if that doesn't come about. Hobbies (including Ham Radio): My many hobbies include photography, flying, writing books and magazine articles and some others but Amateur Radio remains the most-liked hobby. Antenna experimentation is the main adventure, HF is the name of the game. The present goal is to establish regular skeds with son (N5DIM) in Sacramento. This is why more antenna work is in the forecast. What's happening today: Station consists of a Yaesu FT-450AT and a Swan SS200 that I mostly use mobile on 40M and 80M with plans to use on 20M, also. I also have a Heath SB-200 HF amplifier that has been reworked by my friend K4ZHM and has full output on 80M and 40M with less than 50W of drive from the 450. It needs some input tuning for use on 20M thru 10M when using solid state rigs but will perform as designed with older tube rigs. K4ZHM installed on the SB-200 inrush turn-on protection, solid state relay for use with modern solid state transcievers and circuit to bias the amp's plate current to "off" when no modulation is present. Runs a bit over 600W!!! Not bad for an amplifier that is about 40 years old. New 572B's also do not hurt the amp's operation. I also have an FT-2800M on 2M and usually monitor 52S for emergency needs of anyone passing through. Just acquired a Dentron antenna tuner: 160-10M 1KW. Will come in handy when experimenting with new antenna designs. Now need a cross-needle SWR/Power meter to make tune-ups easier. Antennas are a GAP Titan and a B&W folded dipole antenna at 35-ft. The B&W is the most-used (full coverage on all bands from 80M thru 10M resulting in no tune-up when changing bands/frequencies; 160M through the transmatch). Sometimes, especially on 20M (maybe 10-percent of the time), the GAP antenna works a bit better because it is non-directional compared to the B&W antenna. However, the B&W antenna does not show pronounced directivity on HF. Also have a "hamstick dipole" up about 30-ft for 6M but need a bandpass filter to stop operation on 6M from disturbing the cable TV's in the house. Tried running an outside ground but it did not help. Just another area that needs attention. Antennas are so low because I live in a hole... It's in the river bottoms. Used to flood every year but no more flooding after the state cleared out the river beds. The only good thing is that the ground system is great due to being so water-saturated. Still don't know how to make the best use of it yet, though. Several QRP projects are also in process or the planning stage. Plan to get an Elecraft K1 or KX1 -- it is very hard to decide which one will serve best my interests in QRP. Having a ball but too much DX has already slipped by!
