Licensed since December 1956, I've seen a lot of changes in the Ham Radio hobby. It has been a social and technical tool for me throughout my life, bringing me many good friends, employment opportunities, and enjoyable experiences.
I have a somewhat out of date homepage at k7buc.org

Finally! I now have 90 radials under the vertical. What a chore! I could not see a difference for the last 3 radials, but up to 87 there was still a significant change in impedance, showing a need for more. Happily, I'm about done feeding my ground plane system copper.
The antenna is back up! A bit of tuning yet to complete, but happily it works better than before.
Aftermath of the "little" tornado.
The Primary Antenna
HyGain AV-18HT HyTower vertical antenna before radials were installed
Evening view to the southeast
Radials run through the Mesquite and Prickly Pear Cactus areas (Ouch!)
Climbing up to the antenna plateau
Look at the rocks! David, my wife's Yavapai-Apache cousin got the job done.
Note the large piece of "caliche" (calcium carbonate) from the hole in the middle picture. A pick just bounces off this stuff.
It is elastic and tough, and iforms a 10 foot deep layer at the antenna location.
The concrete flows into holes in this layer which gives the base extra strength.
The tranceiver is a Flexradio Flex-3000. It is a joy to use, having by far the best receiver I have ever used. The Amplifier is an Alpha 77, a legal limit amp which employs a single 8877/3CX1500A7. On bands where an antenna tuner is required I use a Nye Viking MB-V.
The vertical antenna is a Hygain Hytower AV-18HT with 90 radials, located 20 feet above and 200 feet to the North of the hamshack on a desert plateau, and is fed by 200 feet of Andrew LDF5-50 7/8" hardline.
Since I have a soft voice, I use a bit of audio processing. A Neumann KM-184 mic feeds an M-Audio preamp into a W2IHY i-Box balanced interface then a Ten-tec 715 Speech Processor drives the Flex 3000.
