Re: WireReady Automation

I've run across it at the local reading service for the visually impaired. They use it to automate overnights and weekends and replay the day's live readings during the overnight hours. I haven't had to take a deep dive into it yet.

Re: BE AM1A Question

Wow...unbelievably stupid for the owner to have no ventilation in a transmitter shack. One of my clients started fighting problems in an 18-year-old AM-500A in a fan-ventilated building. It doesn't take a very large thru-the wall air-conditioner to keep a 10x10 shack cool with one of these transmit...

Re: BE AM1A Question

We got it working again -- as it turned out, the controller card had gone bad causing the power setting trimpots to have no effect and the power to fly away and eventually blow the power module from the stress. What’s the ambient temp in the room? On hot days outside (ambient in the 90's) the transm...

Re: Weird satellite problem

Have you looked at the satellite downlink on a Spectrum analyzer to see what it looks like? It's not unusual for LNBs to start "spiking" across the band, and you could have an issue where one of those spikes are near your desired carrier. Could also be cross-pole. Your cross pole could be a touch o...

Re: BE AM1A Question

So far, so good after yet another module swap. This one was "factory repaired" too, although it still wouldn't surprise me if something else is wrong somewhere. The owner is tighter than a drum and the poor transmitter gets abused because he's too cheap to pay for an A/C unit.

Weird satellite problem

I've run into an odd problem with a satellite dish. Station has XDS receivers for Premiere and Learfield. The Learfield receiver is working fine, Premiere stopped working. Ops guy requested a new box from Premiere, they shipped it out, still no signal. He's tried all sorts of swap outs to rule out c...

BE AM1A Question

I have an AM1A here that recently suffered a partial power module failure. Exchanged the module back to the factory for a good one, and got back to full power. Now it's running around 600w instead of the normal 1080 (directional station). The ops guy ran out to the site and told me that there were n...

USB Keyboards/Mice for Studio

Any suggestions for good USB keyboards and mice that work well in a studio application and stand up to jock abuse?

Re: Blue tooth mixer and high school games

We try to avoid cell calls for ball game feeds as much as possible. Typically we use 4G IP with a smartphone tethered to an old router that I flashed with openWRT, and then connect a Tieline Commander to the router via the Ethernet port. Since we are in a fairly good area for cell coverage, we usual...

Re: BE AM-1A Power Supply

If you cycle the front panel breaker on and off quickly a few times the bad supply will sometimes restart and run until the power blinks again. I have had about 50% success with this. I now keep a spare PS in my truck (one of the few spare parts that I carry these days other than a spare LNB). Inte...

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 i...

BE AM-1A Power Supply

I have a sick AM-1A that has the infamous flashing light syndrome on the controller. I'm familiar with the cause and the replacement off-the-shelf supply (or poaching of Starguide supply) but since I have not done one of these replacements before, wanted to confirm that this supply is the one locate...

Re: The high leg

I saw someone tell a story on one of these engineering groups about an electrician wiring the outlet for a break room Coke machine to the high leg...with the expected results. I seem to remember here at the office they had to stop an electrician from tapping into the lighting circuit since it was 277.

Re: Women Hearing Distorsion on Station After STL realign

That does seem very low. If I am remembering correctly, the manual says it wants to see 40 dBuV for good mono performance, and 50 dBuV for stereo. The LPFM I take care of used to run one of those, and I think we usually saw > 60 on it, but it was for a path of just under 2.5 miles. I assume you've t...

Re: Wanna Play "Guess What's in the Grey Box?"

TFT EAS 911s do not have audio in/out. That's in a separate box, either TFT's or your own home brew. So perhaps this is that. The LPFM I take care of used to have a home brewed interrupt in a brown metal box for this very reason. The TFT 911D they had didn't come with an interrupt relay. It was ret...
