I'm going to need a new dummy load and wondering if anyone knows of
any surplus houses with a good selection. I seem to recall seeing a
site a few years ago with more dummies than you could ever sort
through but the name escapes me. I'm looking for something in the
500W to 1KW range for DC - 30 MHz. without breaking the bank. Is the
Cantenna still the most economical way to go?
Thanks

You're much better off, money wise, going to hamfests. Around here at least
there's still a lot of older, oil cooled Bird loads in the 500 and
1000 watt range
for reasonable bucks. Most of them are fron 2 way radio shops and military
surplus.
On my workbench I have a military GRM-10, better known as a Bird 694. That's
HF (2 - 30 MHz), 1000 watts, with a built in wattmeter. It needed a cleanup and
some minor tweeking of bent cooling fins, but it was ten bucks.
I help maintain a small community FM station; for that reason, in my
pickup is a
Bird TS-118/AP . This thing will handle 500 watts in the FM band, and
has a built
in wattmeter. It'll cover something like 25 - 1000 MHz, and comes in
an aluminum
military transit case, completely water tight and dust proof. Hamfest
price was just
$40.00.
On the floor of the shack is a Bird 82A, hooked to a coaxial switch
so I can dump
the rig into it as needed. Takes 500 watts, no wattmeter, uses QC
connectors, a bit
dinged up but not leaking and quite usable after an overhaul (it was
reading like 65
ohms when I got it; after an internal cleanup it is dead on). Because
of the funny
ohmmeter readings, that one was five buck special at a hamfest.
Just look around... and if you're handy with hand tools and don't
mind getting your
hands oily, don't overlook loads that read high (up to maybe 100
ohms); most of the
time they can be brought back from the dead.
