Re: AM Mast Height?

From everything I've read a 1/4 wave tower (in this case 420 feet) seems to be a "sweet spot" in terms of matching, efficiency, and cost vs coverage considerations. There may be other considerations limiting the tower to 300 feet (air traffic, land area, etc.) but the difference between 30...

Re: 0 Card - Optimod 8100A/XT2 combo?

ftp://ftp.orban.com/ for 8100 a manual, memory is it has info on the XT as well

The point of the zero card was to provide better filtering above 15 KHZ., and achieve more loudness.

Re: Small and robust sound card. Recommendation?

Refurbished Dell towers are available at a reasonable cost..some actually have IDE slots as well as the current PCI-e slot. All have room for full-sized sound cards. I would add a back-up external hard drive to be safe, but I've usually gotten good life from these refurbed computers. Amazon sells a ...

Re: Small and robust sound card. Recommendation?

We use the little Lexicon Alphas on our "streaming" computers (they actually send the audio to the streaming service)--but have been plagued by weirdness mostly caused by Microsoft updates. The Lexicon will just stop working, not recognized by the computer. Usual solution is to just change...

Re: Looking for a list of 24/7 Satellite Programming for Radio - News or Sports or Business or otherwise

Well, for entertainment (I assume music programming) the Westwood One networks (for the most part) use the Wegener satellite receivers with the STORQ system that is pretty much self-contained. The automation system is part of the receiver--it can send a relay contact to trigger an external automatio...

Re: Collins 831G schematic

Little Bext 30 watt exciter, about 20 watts in, a whole bunch back.

Looks like transmitter needs new finals, will probably play some more when the finals are changed.

Re: Disabling Windows Features Updates

Nothing like getting a silence sense alert in the middle of the night, only to find a Windows update has uninstalled your sound card. Yes, I know, not supposed to have the air computer on the internet. But with three stations--sound to be four, two studio locations, and staff scattered all over...es...

Re: Quality translator

At my one site the BW is on 107.9, while the full power is on 93.9--at 17 kw erp off a 4 bay. The BW won't make power reliably--folds back. The VS300 comfortably made the required power--but didn't have a processor available to use the internet feed so had to go off-air with a weak signal. We're buy...

Re: Suggestions for FM Tuner

More I review this discussion--cheapest (though not that cheap) solution is: A: buy a good quality FM tuner off E-bay--particulary a high-end brand with slide rule tuning (so it stays tuned during power outages)--and use that for the air monitor, and B: Pickup a used Inovonics mod monitor. It's self...

Re: Quality translator

Also submit my vote for the VS300. On 220 volts--as noted supplies have been upgraded to work on 110. However, I have one that's been on the air for several years using a 110 to 220 upconverting device I bought on Amazon. Several other problems with the BW broadcast units: 1. They don't play well wi...

Re: Simple audio swithcer for two sources

Not quite clear as to what you are looking for. I use the Broadcast Tools switchers which can switch either two or four stereo sources to one output (two different models). Can be remoted.

Re: Disabling Windows Features Updates

Side note on this discussion. We needed another editing workstation. We purchased a "refurbished" Dell because this particular tower model still had an IDE slot--so we could use an older but still good ASI soundcard. Went around and around trying to activate the new copy of Windows 10. Fin...

Re: source 950 combiner

The path is quite short, just over two miles. At the top of the 60' STL tower, can see the FM tower. Most of the loss is in the cable run--around 200 feet, using 7/8th now. Plan on using that cable for the BE-1A when it is moved. If the combiner price is reasonable will just get two more lengths of ...
