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. Finally disco...

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 ...

source 950 combiner

Adding station-need 2nd STL. Need a combiner for the two STl's as eventually the STL antenna will be on the AM tower for the second station (the 2nd STL will be for the associated translator). 949.0 and 946.375 Suggestions on brand /source? Of course, we are only talking about ten watts from each tr...

Re: Armstrong X-Link transmitter

I came across what I remember as an RVR style box (Bext brand maybe) which was composite in--but had discrete outputs on the receiver. At least that's what it looked like.

Most of these RVR's I've come across are straight composite STL's. Front panel varies, rear panel similar.

Re: Armstrong X-Link transmitter

New supply brought it back to life. Not the cheapest route but have other projects coming up I need to worry about.

The supply feeds a ribbon cable, so not easily replaced with a generic supply. Will re-cap the old supply as a spare, as have two of these transmitters

Re: [Project] Measuring a listener's tolerance to the quality of audio files

Perception of audio quality can depend on what the listener is using to hear the audio. Go back 50 years. Most people would find audio quality on a typical telephone handset as acceptable. But the same audio pulled off the line with a hybrid & broadcast on an FM station would be perceived as "thin" ...

Re: Armstrong X-Link transmitter

Just noted something on the schematic which would be handy for American manufacturers to add--radial capacitors are described not only in capacitance and voltage rating but also in diameter (millimeter, but that's fine). We've all had fun squeezing over-sized caps into a tight circuit board. Most su...

Grazie molto!

Better Italian than pinyin.

Leaves me to suspect failing supply, at least leaky caps. Ten year old unit.

Re: New engineer - questions

No offense taken. We don't need anymore stations in our market. There are 6 AM's in our market. All but one have FM translators, four of the five AM's rent space on my FM tower for their translator antennas. We get one of these translators with the AM we are buying, along with a second out-of-market...
