Re: Required acres of land

Not that they ever fall and lay out their full length.. Actually we had a tower fall in more or less a straight line. It was a 280-foot AM stick and was literally blown flat by a tornado. The wind lifted the base insulator up off the bottom pivot plate and everything fell sideways. The tower landed...

Re: New member - LPFM transmitter recommendations

The VS-300 is 220 volt, but have one running on a 110 to 220 transformer I got off Amazon. Been running that way for several years. Nautel may be able to supply a 110 volt version now. The later model VS-300s have an upgraded power supply that will accept 110VAC on up to about 260VAC. We have a who...

Re: Splitting coverage into markets

I believe OP is outside the US.

Wide Orbit has something they call "leader-follower" that does automated split insertion. Not cheap but that's how the big boys (allegedly) do it. Some of the other automation providers may have similar solutions but that's one I know about.

Re: DX-10 Controller Probs

I didn't think it was that old either....but there's this: https://www.desmoinesbroadcasting.com/kioa/harris-dx10.html Says the prototype went on air in September 1987, or very nearly 30 years ago. Back to the topic, I assume you have checked all PS voltages and shaken the big blue caps to see if th...

Re: Dead Harris - X1000B Suggestion

I have not dealt much with BE AM transmitter support, but we have a couple of BE solid state FM boxes. One of them was partially under water for a couple of weeks after a hurricane last fall. We got it working again but it shows signs of being a problem child for whatever time it has left. BE was pr...

Re: Has anyone received the new Nielsen monitors?

We got ours not long after I turned in the paperwork (and boy howdy did they pester me about finishing that). They are still sitting in their boxes in the rack room. I just haven't had time to clear out multiple rack units of space and pull new wiring to get them working. I have no clue whether PPM ...

Re: You need this

Don't bother unless your house is wired with oxygen-free Romex. And never mind the miles and miles of "ordinary" conductor between your house and the power plant.

The "reviews" are unintentionally hilarious. "They even checked my order to make sure it was right!"

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

AMC-8 seems to be back up today on our "nightlight" receiver. EB is varying up and down by a couple dB or so. Guess somebody at SES is having some fun with the knobs 8)

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

I left one of our (unused) receivers connected to a dish pointed at AMC-8, just to see if we could tell when they turned it off. Just walked by it a short while ago and it looks like it's down. 20170712_185643.jpg Is it off for good? I think the unofficial note we got said the bird operator might be...

Re: Collins 310W-1 Exciter Divider

Dale:

I found an 820E-1 manual here in our shop (no idea what became of the transmitter). In our manual, the part I think you are looking for is called out as SN1147.

Hope that helps.

Tower lighting

Has anyone had experience with Unimar LED tower lighting systems? Looking at replacing a strobe system on a 50KW AM tower.

Feel free to PM or whatever...thanks.

Re: Daytime Impedance high?

When Harris had their big inventory sell-off a few years ago (prior to the broadcast division getting spun off and becoming Gates-Air), did they have any AM parts and pieces that wound up being purchased by someone? I recall that SCMS wound up with a fair amount of Harris stuff.

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

Apparently I didn't armstrong the bolts tight enough on this Comtech dish. Wind spun it a little bit over the weekend and there were a lot of unhappy receivers.

The engineer who fixed it took one of those "thousand word" pics. Insert your own caption....

Re: Streamer PC hit by ransomware

As far as I know, the machine was hooked up directly to the DSL with no firewall. And yes it probably had TeamViewer on it. My staff guy working on it thinks it may have come from the factory pre-loaded with the stuff. Not sure if I'm buying that, but can't rule it out. The first attempt at recovery...
