Heathkit Gear
Here are some better shots of the Heathkit gear that I have collected from
numerous hamfests etc. Most of the equipment needed minor work
to make it perform correctly when I bought them; but they all work fine
now.
SB-200 Linear
Heathkit specs say that this linear is supposed to do 1000 watts.
I have never talked to anyone that owns one that gets any more than about
800 watts out of it, and that is also what I get. The linear
uses 572B tubes (very plentiful). It works great when I really need
some extra punch on 40 or 80 meter SSB. Since I work mostly
CW it seldom gets used. The amplifier is in really great shape.
HW-8 QRP CW Transceiver
I picked up this little guy at a Belton, TX hamfest
about two years ago. It had a dirty relay in it when I bought
it, but I had it on the air and had made five or six QSO with it the same
night that I brought it home. Since then, I have added several modifications
to the radio: I added an S meter function to the power indicator,
Changed out the capacitors and a couple of resistors in the Audio Amplifier
to improve the sound, Added a FREQ-MITE frequency annunciator, Replaced
the rca jack on the rear panel with a BNC jack, corrected the offset
between tx and rx, and I added a tap for hooking up a frequency display
to the unit. Thats it for now; but soon plan on adding the
mod for RIT. Almost all of these mods can be found in the HW-8
Handbook.
GD-1 and GD-1A Grid Dip Meters
Also picked these up at Belton several years ago.
To be honest, little has been done with them and I would be real interested
in hearing from anyone who has the schematics for either one of them.
I am also considering gutting them out and replacing all of the internals
with a transistor GDO which may make them a bit more portable (they require
117-120vac in present condition). As you can tell from the
photo, the GD-1 still needs a bit of work.
HD-1418 Audio Filter
I paid only eight bucks for this little guy at the
Dallas Hamcom swapfest. It works fine in the CW modes that
I use it for and is cosmetically in great shape.

HO-10 Monitor Scope
I bought this guy at a Belton Swapfest back in 1993.
I paid $40 dollars for it and all I could get out of it was a horizontal
line. I did'nt get a whole lot of use out of it until I packed it
up one year and brought it with me to Laplace, La. where my brother Bob,
KA5ZCI, lives with his family. Bob works for Bell South and
is a real electronic WIZ. We both played with the rig for quite
a while one day and Bob eventually figured out that the original owner
must have been a bit dislexic. All of the wiring on the yoke of the
oscilliscope was reversed! Once that was repaired the little
scope starting working perfect.
Impedence Analyzer
Also bought this at Belton swapfest some years ago. Works great on
balanced line antennas.
