Re: Harris FM K5 Freq Change

The metal band connections from the tube anode to the PA tank tubing are aluminum. There may be some dimensional info in the data. Use a very long stainless hose clamp,or two if you can't find real long ones. I think those were 1/2 inch width. I seriously doubt that you will be able to get the PA ef...

So what was the snake-oil that he found?

As I recall the detail, his FM-20G had taken some kind of hit----possibily lightning. It totally messed up the IPA. Story goes that he fiddled around with the coil and possibly moved things around. He put things back together, fired the brute back up and tuned for max smoke. He got his TPO, but it s...

Re: Harris FM G thru K series

Just a bit of history on those boxes. The FM-G, H, H2, H3 and K series all used the same half wave pa cavity design.....just different pipe diams as you got into the higher powers. The big improvement came when a customer suffered severe damage in his FM-20G. He did some "on site mods" to get back o...

Re: Harris FM K5 Freq Change

TVRADIOGUY: I have searched my test data sheets and am sorry to report I don't have factory test data sheets for an FM-5H/K series anywhere close to 106.1. Nearly all are for below 100 mhz. The file I posted hopefully will contain enough info to get you close to where it needs to be for your new fre...

Re: Harris FM K5 Freq Change

There are a couple items in the ipa/pa section that will require change.... 1) coil in ipa section 2) the metal fixtures that connects the anode of the tub to the pa tuning tube. These areas, I believe, are listed in the directions. I don' recall if dimensions are listed as I haven't looked at the i...

Re: Harris FM K5 Freq Change

No current experience with rotary converters so I will leave that to those with recent experience. I will, however, offer that way back when I was selling for Harris, there was a pretty good rotary converter out there and to the best of my memory it was a company in Indiana. Just found it in the arc...

Re: Harris FM K5 Freq Change

Attached is a pdf from the Harris data base that should detail everything you need to do the change. The one major problem you will run into is the availability of some special parts to do the change.

Re: Tower Painting question

So.....are you the one with only the nose and sunglasses visible??? Surely it couldn't have been that cold! I bet it was all of +30 degrees----that's above zero.

Re: Harris FM K5 Freq Change

I need to have some specific information to provide the right info. Is this xmttr using a 4CX5000 final, and is it using a 4CX250 driver tube, and which exciter are you using? What operating frequency is it on now, and what freq. will you be moving it to? If this is the older box, sold up thru the 1...

Re: BE AM-1A Power Supply

Ya sure, you betcha! That's the one. Look at it carefully and you should see a couple of screws on the metal cover. These screws go into mretallic standoffs. Pull those screws from INSIDE the controller enclosure, not outside. That will reveal the power supply in all it's "living color". The rest is...

Merry Christmas and Happy New Year to everyone from Racine (actually Caledonia). It is an honor to be part of the great crew hanging out on the site.

back in the '80s had a 5S150

You ain't old. My first console in the fall of 56 (that's 1956) was I believe a Western Electric at KWGS FM Tulsa University with the red and black knobs. That's almost old. When I got the job at KVOO in Tulsa in the Philtower, in the spring of 57, they were still using a home made console that had ...
