The VHF/UHF weak signal station. On the left of the top shelf is a
Mirage 3016 160 watt amplifier for 144 MHz and a Tokyo Hy-Power HL-60U
60 watt amplifier for 432 MHz. On the right of the top shelf is a
Realistic HTX-100 ten meter transceiver and a Downeast Microwave
28-222CK transverter for 222 MHz.
|
 |
On the bottom shelf is an Astron RS-35M 13.8VDC power supply, a Yaesu FT-726R
transceiver for 144 MHz and 432 MHz (with cabling for HSCW via a computer
sound card,) and a Kenwood TS-600 transceiver for 50 MHz (complete with the
VOX-3 accessory.)

The HF station. On the top shelf is an AEA PK-900 multimode terminal node
controller with a small 13.8VDC power supply and a homebrew microphone
switch sitting top of it. To the right of the computer monitor is a
Kenwood SP-230 speaker and a bell.
|
 |
On the bottom row is an 80486DX4/100 computer, running Windows 98, a Kenwood
TS-830S MF/HF transceiver, the Kenwood VFO-230 external VFO, an MFJ electronic
keyer (no memories,) a CDE HAM-IV rotor control box, and a Kenwood AT-230
antenna tuner. The paddles on the table are a Bencher BY-1.

In the 19" equipment rack, the club has a Heathkit SB-220 HF amplifier
(up to a kilowatt out on 80, 40, 20, 15, and 10 meters,) a patch panel
for using differnet HF antennas, a Yaesu FT-227R "Memorizer" transceiver for
144 MHz FM, used exclusively for packet, and some sort of 50 MHz FM
crystal-controlled transceiver. The dot matrix printer was only in the
shack for a few weeks.

The grid maps above the VHF/UHF gear show the grids worked and confirmed on
each of the four VHF/UHF bands the club had at the time: 50 MHz, 144 MHz,
222 MHz, and 432 MHz.
|
 |
The 222 MHz gear at N5XU was a transverter, built from a kit by Ken KM5FA,
and a ten meter monoband transceiver slightly modified by Ken KM5FA with a mod
developed by Rus K2UA.
|
 |
Ken gave the transverter a custom paint job and labelling, and changed
the power LED from red to green.
|
 |
Ken KM5FA built a custom cable to use the Yaesu FT-726R for high speed
CW meteor scatter QSOs, using DSP software and a computer sound card.

sound card software for meteor scatter work. You can visually see
a meteor ping in the display.
