Hey, I am not a ham, for that matter not even a practicing broadcast engineer anymore, but I still think this is very cool.  Thanks for sharing the story and pix.

Looking forward to an update from the gent building an amateur rig with an MSDC klystron.

Hi Group:

 

I just thought the hams on the list might like to see the progress some others have made with the old channel 2 amplifier modules on 6 meters.

Gang.....

Remember the WCBS-TV transmitter amplifier modules from the replaced analog transmitters?  About 30 or 40 of them were given to hams all around the US.  Here's mention of one in the Denver SBE Chapter 48 Newsletter.  

In case the picture of the amplifier module on the bench being fired up doesn't come through the email list (it probably won't) you can read the complete newsletter at:

or jump straight to Jack Roland's Hamshack article at:

CBS's Alan Parnau dragged these modules down from the 83rd floor, the Hams of the World thank you.  And thanks to Bob N2OML whose idea it was to put these modules to use on 6 meters.

This is from Jack's article:

==========================================================

Another great project that I have a real interest in is what my friend Kenny, K4KR in Chickamauga, Georgia near Chattanooga, Tennessee has been up to lately.  He obtained an amplifier module from Bruce, WA2ZST, who is an engineer with CBS-TV in New York City, which originally helped to power the Harris transmitter for WCBS-TV.  Kenny has built a 50 volt 50 amp power supply to run the amplifier, and will soon be putting a kilowatt out on 6 meters with this!  What an historical and cool piece of gear this is!  Several of these were obtained by ham operators around the country and are being converted for ham use.  Once Kenny gets this all racked up and mounted in his shack, he will be feeding a big 7 element with a 28 foot boom 6 meter yagi with it and will truly be a “big gun” on 6 meters.  More on this story as it develops!
