My main HF antenna is 51-foot (16-meter) crank-up tower has an M² KT-34M2 (tri-band 20, 15, and 10) antenna on top. I added a motorized winch to run it up and down. The rotator is an AlfaSpid RAK-1. I usually keep the antenna at 36 feet (half wavelength on 20 meters), but run it all the way up for contests. The 160-meter antenna is an inverted-L running parallel to the tower 20 feet (6.1 meters) and then 105 feet (32 meters) to the corner of the lot. In February 2015 I put up a north-south oriented off-center fed (OCF) 80-meter dipole that gives me capability on 80, 40 17, 24, and 10 meters. In 2017 I added a second OCF dipole oriented east-west. The roof also holds a NewTronics 4BTV and a 2-30 MHz receive-only shielded loop antenna. VHF/UHF antennas include two 144/430 colinears, a 2-meter horizontally polarized omnidirectional antenna, an aircraft band J-pole, a discone, and a 6-meter stacked 5/8 wave vertical.

In addition to my amateur radio activities I volunteer as a pilot for the Flying Samaritans. We provide no-cost medical and dental services to underserved communities in Baja California, Mexico. Their website is: http://www.flyingsamaritansaz.org/Tucson. Unfortunately I have not been able to obtain a Mexico amateur radio license, so on clinic weekends I just eat fish tacos and work on maintaining the clinic after flying the medical and dental personnel down.

To keep life interesting I also sing in a barbershop chorus and go on scuba diving trips.

Back to amateur radio, this is my basic equipment that I have accumulated over the last 40+ years. 

  • Yaesu FTDX-3000 running 100 watts SSB & CW, 20-50 watts digital
  • Ameritron AL-1200 runnng 1200 watts PEP, 500-900 watts on RTTY
  • MFJ-998 1500-watt Automatic Antenna Tuner
  • Heil PR781G microphone for the FTDX-3000 and VHF radios
  • QRP rig is Ten-Tec Argonaut 509
  • 6-meter AM rig is Gonset G-50 to a Diamond colinear antenna
  • Astatic D-104 microphone for the Argonaut and Gonset
  • Yaesu FT-227R witha a SignaLink USB interface for VHF digital work
  • Yaesu FT-897D for VHF/UHF SSB and portable operation
  • 35 Amp-Hour battery and 45-watt solar panel for backup power
  • Rigol DSA815 Spectrum Analyzer (1.5 GHz) 
  • Siglent 200-MHz Oscilloscope

M2 KT34M2

Here I am adding the tower cable standoffs that were custom made for me by KF7P Metalwerks.

Current shack configuration

The roof has a lot of antennas.

Two of our rescued greyhounds, Atilla and Connie, often accompany me when I am on the air. Unfortunately, Connie passed away in 2017.

Now it is Attila and Valerie. They can sleep thrrough a phone contest.

Shack Dogs

The tower base is three by four feet and is seven feet deep (1 m x 1.3 m x 2.5 m) and
has three ground rods. I am in the process of adding six more ground rods.

 

The box at the tower base has the protection for the rotator and a key-operated
relay to power the tower winch motor.

 

The HF antennas go through a remote switch. VHF and UHF antennas are direct.

 

The entrance panel has three ground rods and Polyphasors. The loop antenna rotator wires (top center) have MOV devices for static protection. The station equipment is on the other side of the wall.

 

The the inside wall from the entrance panel has connectors for six antennas,
the rotator control cable, the antenna selector control, the solar panel battery
charger wiring, the main inside ground bus, the loop antenna and its rotator.

 

My new QSL Card shows the tower and antenna looking east toward the Catalina Mountains.

My previous QSL Card uses an in-flight photo of my airplane over the Sea of Cortez east of Baja california. I have some left if you want a QSL and would prefer one of these.

  • I had some antenna restrictions, but I managed to put a few antennas on a flat roof, which is about all a flat roof is good for.
  • 10-10 Number 2435
  • ARRL Arizona Section Technical Coordinator
  • Active in Flying Samaritans flying medical personnel to under-served people in Baja California (www.flyingsamaritansaz.org/tucson)
  • Active SCUBA diver, mountain biker, and woodworker

Here are two pictures of my shack in 1980.The Model 15 teletype made a lot of noise. I still have the D-104 microphone, Ten-Tec Argonaut 509, FRG-7 receiver, Heathkit wattmeter, phone patch, Eico grid dip meter, and FT-227 Memorizer 2-meter transceiver. My main rig was a Heathkit HW-101 that I assembled in 1971. Not shown is a homebrew kilowatt linear amplifier that I made from scratch using a pair of 813 tubes in a grounded grid configuration.

The RTTY transmitter is the Viking Ranger with a varactor diode in the VFO circuit. Unfortunately the old QSL cards got lost in a move.

This angle shows my homebrew kilowatt amplifier that used two 813s in grounded grid.
