QSL image for K5RCR

Greetings;

 

I was first licensed as WN6HGY in 1968 and with many moves, obtained calls WA6EZT, N9COO, N7GEF, KI8GX and finally, K5RCR. I have been fortunate to also operate as ZK1RCR [Cook Islands] and V31RC [Belize]. Ham radio provided my entry into a career in science - I spent many years as a neurophysiologist at UCLA, Northwestern,University of Nevada, Ohio State and now LSU.

 

Rig in the header is a Ten Tec OMNI VI for 160-10 and an FT847 for 6 meters- a carryover from my satellite "phase". I also use an RF Space SDR-IQ as a spectrum scanner. Amps include an AL811 and an ancient Hallicrafters HT41 converted to 6 Meters. Antennas are a 4 element yagi for 6 meters, a 3 element yagi for 20-10 meters, a hygain hytower for 80-10 meters and a 60'"cage-T" for 160 meters. Contacts are verified by LOTW but am happy to send out QSL's.

 

The next image is my 50 year old "boat anchor" rig; a Knight T-150 and a Hammarlund HQ-170. This was pretty close to my 1968 Novice rig. This Knightwas just as bad, drifty and chirpy as most of them were. But after making a few measurements I discovered that the plate voltage on the driver tube dropped more than 100 volts when the rig was keyed...No wonder they chirped and pulled the frequency when keyed! I put a couple of OA2 regulators in series and connected them to the plate of the driver and ...NO CHIRP! She is vey well behaved now and I am not ashamed to use the VFO!

 

The next image shows my "new" version of a common (for 1941) homebrew two tube, 10 watt transmitter[6ag7 + 807] and a 4 tube regenerative receiver [75+6sq7+6sq7+6f6]plus a power supply. The first 6SQ7 is hooked up as a cathode follower between the detector and the first audio amp. This enormously improves stability. Had my first qso on this rig within a few minutes of firing it up for the first time. The QSO was with K8JD - about a 1000 miles north of my QTH. That feeling can't be beat - working someone that far away on a rig that was a pile of old parts the week before!
