Re: Weatherized cable/antenna identification tags

Doesn't quite meet you criteria but you might want to consider plastic livestock ear tags. They commonly come sequentially numbered which would require a separate database but can be ordered with custom imprinting (and you can always mark one side with that name/address/ info yourself). They're also...

Re: Continental 816R-3C IPA

Have you looked at the load on the IPA with a wattmeter? Solid state IPAs (and solid state transmitters) are generally unforgiving of a load that isn't close to 50+j0. It would also be a good idea to see how it plays into a dummy load. And that dummy load test of the existing amplifier . . EXCELLEN...

Re: Continental 816R-3C IPA

The company that Mr. Pearson's WEB site refers to, Broadcast Concepts, also offers a repair service on those amplifiers. The price of $450 is pretty good too given that they replace both transistors, which are over $100 each. http://broadcastconcepts.com/700W-SVPA.html They also have several 700-wat...

Re: New member - LPFM transmitter recommendations

Well, looks like Nautel is out of the running. I sent them a message several days ago with 3 simple questions about the VS300 and no one responded. Simply unacceptable. If they can't service me before the sale, I have to question how they will service me after. Before you give up on Nautel complete...

Re: New member - LPFM transmitter recommendations

My issue with BW is their analog design. Sooner rather than later you will need a real engineer to put it back together. Gatesair and BE may or may not be around for long. If support is an issue, be wary. As I said earlier, Nautel or Ecreso (Crown E). Let your spreadsheet decide. Just curious, but ...

Re: New member - LPFM transmitter recommendations

Boy, all the Nautel "cultists" are out in full bloom on this. And that's what Nautel has become for reasons that totally escape me. A cult. (Maybe it's the old "no one ever got fired for buying RCA" mentality?) I've tried hard, REALLY hard, to find reasons to like Nautel but I got . . . nothing. (OK...

Re: New member - LPFM transmitter recommendations

I'd give BW Broadcast equipment a look. Their TX300 V2 weighs in at under $3,500, complete with audio processor and stereo generator. I've got a client that has a number of them used as translators and they just work. (Yeah, they're made in the UK so far as I know but nothing is perfect.)

Re: EAS Issue

Here's a link to a Crawford Broadcasting engineering newsletter that discusses the possible issue. Does sound suspiciously like what you're suffering, doesn't it? If the PPM encoders were screwing over EAS tones, every station in the land would be screaming, but they're not (I presume...?) so it mu...

Re: EAS Issue

The EAS "tones" seem to make it through the system in that they can be heard on air. But EAS decoders (multiple SAGE units, and possibly other brands) can't seem to decode them "off air" after they pass through the AXIA system. This is a long-shot, but I wonder if it is a similar issue to trying to...

Re: EAS Issue

I got nothing except to ask if you've talked to Kirk Harnack. No, I've only talked to someone in support. But that's a good suggestion if this problem does end up being an AXIA issue. Either he or Marty. But recent information has me thinking that while it is a problem with the system architecture ...

Re: EAS Issue

In our group, the EAS is after all switching regardless of whether we're operating in AoIP or conventional. Insertion is after the delay, all pre-processing, emergency bypass switches, everything. We use a pair of TFT 940 multi-station insertion units for feeding four stations just before each stat...

Re: EAS Issue

Thanks for the reply Shane but I didn't say anything about having to have a "pot" open on a "control surface" to make the mess work. The set-up appears to be more of a virtual switcher situation where the AXIA system switches away from the Program source for a particular station and to the EAS sourc...

EAS Issue

I'm curious if anyone has had any experience running EAS "tones" from a SAGE unit (or any other brand of EAS encoder for that matter) through a Telos AXIA system. If so did you have any issues with the "tones" making it through the system intact? Reason I ask is that I have a small station group tha...

Check out these guys . . . http://www.avateq.com I was seriously considering one until I ferreted out a used R&S EFA.

Re: FM Composite isolation

That 75-ohm hose has similar capacitance/foot to RG-62. RG-62 weighs in at around 13.5 pF/foot, 1694A has a capacitance of about 16.2 pF/foot. Now try it with about 100-feet of RG-58 which is about double RG-62 at 26.4 pF/foot. I'd be curious to see how a 100-foot run of RG-58 degrades the composite...
