The VA7ST station has a new contesting amplifier — the Ameritron AL-80BX joins a pair of SB-221 amplifiers for high-power operation. See how they matched up in the DRCG Worldwide RTTY contest, and general thoughts about both approaches to QRO contesting.
It’s time for a podcast devoted to amateur radio contests. Now we have one. Welcome to Zone Zero.
After two years of “all talk, no action,” the radio room has been rebuilt.
An overview of my SB-221 amplifier repair project — a notebook about what it needed and what I did.

Expand a 40M rotatable dipole into a 2-element yagi with a fixed wire element. Add a relay to the wire and get instant 180-degree rotation, too.
Tired of burned-out bulbs in your CDE rotator meter? Replace the bulb with an LED strip — it’s inexpensive and LEDs will last a very long time.
Big plans for the radio “shack” at VA7ST… will it ever be built?
