[HoustonHam] [Microwave] Parting out 6 GHz gear

Chris;

This was not STL gear. These were network feeds pre-satellite. Fairly 
old gear; TWTs'. Have all the manuals and maintenance records but I 
would never consider placing them in service, even for amateur use.  The 
technology is just too old. The PLOs' are useful as is some of the hardware.

I thought STL was in the 1.8-2.2 GHz range. It's been many years since I 
was involved in broadcast.

I do have some Terracom units used for STL. Still trying to decide 
whether or not to modify the units for HAM use; maybe for ARES disaster 
assessment applications.  Again, no dishes with them!

The repeater is a Micor with a loaded S-Com 7K controller and the can 
set is WACOM WP-609. The Wacom gear and S-Cam were new when I got them.

There are a number of spares for the repeater including a spare set of 
channel elements on the repeater frequencies. Full documentation, of course.

As soon as I catch up on some maintenance I hope to get back on 23cm 
(ICOM 1275) and then on to 10 GHz.

FWIW I have a fairly complete machine shop shop here; no large gear but 
well equipped. The lab goes up to 22GHz; mostly HP and Tek a couple of 
generation old but still in good shape.

Dave, W5WP
