Re: Monitoring, Day Sequerra Board Repair

WPRO in Providence took theirs and modified the bar-graphs to be a dimmer, easier on the eyes green color. I remember their engineer telling me how they modified the unit because the blue was too harsh.

To find out what C-band freq you are looking at, subtract the indicated freq on the specan from the LO of the LNB (5150mhz).
And hope the LNB is using a standard L.O. of 5150 and not one of those odd-balls. While 5150 is normal, I have seen some unusual ones on older dishes.

Let me see if I have a copy of the routerworks software I can let you borrow.

Burk Auto Pilot Win 10 display issue

I am having a brain fart on this. On our Windows 10 Burk Auto Pilot machine, the display is all screwed up. The file-edit-view bar is at the bottom and windows are strangley stacked on each other. IIRC, the fix for this is to delete a file, but I can't remember which one. Their support is gone for t...

Re: Silent spot

I worked for an AM station awhile back that had a sponsor for pattern change. I had heard a story, not sure if it was just internet fodder or true, of an oil company that sponsored a pattern change. Would list towns they serve in the day pattern, then it would switch, and continue to list towns ser...

Re: Silent spot

Or the Hollywood Exchange spot, that aired on NBC Network. Started out with bars and tone.

That was a fun one when it aired, and because it was on network, we got no local indication it was going to air.

They sold reasonably well in the international market, but pretty much bombed in the US.
I seem to recall they used vapor phase cooling in their UHF transmitters back in the 1970s.
WSBK-TV in Boston had a vapor cooled UHF transmitter.

Re: GatesAir suspends AM TX sales (Radio World)

If New York is any indicator they won’t be selling many TV transmitters either. All but one station so far have purchased Rhode Schwarz. Well NY isn't an indicator. GatesAir is selling a TON of post repack transmitters. I can attest to several markets where 90-95% of the market will be Gates Air. R...

Did you try googling using the Rat Shack part number for the unit itself? Many times I stumble across service manuals using that method instead of the model name.
Yessir I did both. No avail.

Realistic Service Manual Request

So I have an old Realistic STA 12, that I love and don't want to part with. One of the giant filter caps decided to give up the ghost. (16v 3300uf, Mouser part cheap). But I want to shot gun all the caps while I have it apart, and having a schematic or service manual would make that job so much easi...

Re: X-Y protocol??

The FS2 will frame-rate convert, although there may be limits...I haven't looked. We have one converting two devices (an Apple TV box and a grid cam) from 1080i60 to 1080i59.94. The FS1 certainly can't do that. I've got to mind the fans, or I'll lose a power supply. Just restocked supplies of both....

Re: X-Y protocol??

Just to make it a bit more confusing, you could route it into an Aja FS-1 set to output 1080i/59.94 -- but if the input video was 60.00, that's what you got on the output. (I'm still having trouble believing that part happened, but checked it enough times...) Yup. Believe it. The AJA FS series (FS1...
