Free to good home —

Build your own VHF, UHF antenna, or use as support for HF, etc. – Tapered fiberglass antennas up to 18 feet long. There are old commercial mountain-top antennas, mostly useful for construction which may use equipment like the one on this informative post. Can build colinear antennas inside, run wire inside or wrap wire coils outside to make HF antennas, or use as support for other antennas. Bases are about 2″ diameter or so. Email me for details and pictures.

Disassembled DB Products 225-B Low Band 3-element Yagi. 7 db gain over a dipole. Currently around 38 MHZ, could be converted to 6 meters. Folded dipole driven element, end mounted boom, Google “WISCO db230” to see latest version.

Two Motorola MICOR Low-Band 100 Watt former CHP mobile radios with dual receivers, one currently on 52.92 and 52.525. These are big radios – 25X13X4 inches. If nothing else, makes a great 100 FM watt amplifier for low power exciter. Misc. control heads, speakers.

GE MLS mobile programmable UHF radio, currently programmed for a FRS frequency.

GE Mastr Executive II UHF mobile radio

Regency UHF repeater, Microcom V01RA. Listed as 453.475 TX 458.475 Rx, 0.5 watt Transmit, 0.5 microvolt Rx.

Connect Systems Private Patch IV (that’s “4”) telephone interconnect for a repeater (both send and receive calls)

Nems Clarke Telemetry Receiver model RX R1037F, 19″ rack mount, with 215 – 260 MHz and 2150 – 2350 MHz plug-in front ends and built in spectrum display unit.

Low Band 3-element side mount beam antennas, could be converted to 6-meters.

Two single feed element Direct TV dish antennas

General Club Meeting – March 15, 2019

The March 15 meeting will feature a presentation by Steve Noll, WA6EJO, on antennas and propagation.

This will be a live demonstration exploring radiation patterns and polarization of a variety of antennas from ground planes to loop Yagis to helices, plus actual demonstrations of a variety of propagation phenomena including ducting, refraction, diffraction, knife edging, Fresnel zone, velocity of propagation, and more.

If you would like to know more about the black magic of radio waves and how to use them, you don’t want to miss Steve’s presentation. He is an expert in the field.

Steve Noll, WA6EJO, has been active in Ham Radio for the past 40 years. He pioneered 2-way Amateur Radio Laser communications in the late 1970s and operated an experimental 23 centimeter repeater and an X-Band beacon in Ventura for many years. Steve chaired several of the West Coast VHF/UHF Conferences in the 1990s where he also built and ran the antenna gain and pattern plotting range. He is a member of the Amateur Television Network and is a founding member of the MAKE Ventura makerspace. Steve retired from Advanced Photonix after 22 years as their Senior Test Engineer.

We had another interesting net tonight with 12 check-ins, and net control Ken, KA6KEN. Tonight’s topics included:

  • One antenna is causing RF interference in the shack, any suggestions?
  • Working digital modes JT8, JT65 and JS8Call and seeing contacts in the waterfall and hearing the signals from the radios audio but no decodes. Same configuration, same computer, downloaded newest versions of WSJTX, JTAlertX, JS8Call and still no decodes. What gives?
  • Local repeater and Echolink discussion.
