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...

Streamer PC hit by ransomware

One of our radio station streaming encoder PCs was taken down over the weekend by ransomware. I don't know which variant it was. We use Triton as our streaming provider. The PC is dual-NIC'd with one NIC going to a DSL for the outbound stream, and the other pointing to the local LAN to pick up artis...

Re: Burk ARC-16 ESI Card

If the ESI will not answer incoming calls, but is otherwise working (calls out OK), the ring detect optoisolator may be bad. On the older boards this is a 4N35, socketed and pretty easy to find and replace. I had a Burk remote control at one site that developed distorted audio on phone calls. Turned...

I'm thinking about taking one of those black mesh POS dishes and making a fire pit out of it.

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

Last Friday, I went back for another try at the crappy mesh dish that kicked my a$$. This time I had a helper. After thrashing around for awhile and not finding any useful signals, we finally lucked onto the right combination of azimuth and skew, and the correct waveforms magically appeared on the s...

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

Yesterday I made an attempt to repoint one of those crappy old black mesh dishes at AMC-18. It was an utter goat rodeo. I had TWO spectrum analyzers, a fresh LNB, and pictures of all the relevant transponder pictograms. I could not see anything on either instrument that matched the pictures, at any ...
