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.
