Re: Transmitter Nitrogen Issue

As others have suggested...get some soapy liquid and baste every fitting you can get to on the ground. Check the regulator itself and it's connection to the nitrogen bottle. I have also had the regulator creating leaks. If the line will build pressure then of course, you're going to feel outflow whe...

Re: Harris/Gates support

They ended up selling us an HT30/35 IPA Power Supply retrofit kit that might work for $1200. I'm happy to report that she's been happy ever since... but this transmitter is less than a decade old and they won't support it? How ridiculous is that! $1200? Is it gold plated and capable of doing your t...

Re: Sine Systems RAK-2

I bought one several-many years ago. I never got the web side working correctly. The guy who owned Sine Systems (senior moment - can't call his name) died soon after I got mine and I never found anyone who could help me after that. I still use it today for the UPS feature. There was a guy in La.- na...

Re: Starlink LAN

The Starlink simplex LAN is included for HD data transport and works well for that purpose.
There used to be an issue with running audio codecs over Lanlinks but can't remember what the problem was and if it has been resolved.

Re: How Old is Old?

Lee: I'm also trying to decide on replacing, or refurbishing a 30 year old ERI 10 bay rototiller. I have never had a single antenna problem in my 22 years at the station but the site became standby a couple of years back and I worry about reliability. It's a bad day when both your sites refuse to pl...

Re: Missing FM pilot

Hand wired electronics did have that unique smell. I always thought it was due to "tube warmth" heating those waxy capacitors but Deep Thought is probably correct about it being from the shellac used on the transformers/chokes.

Re: Theory Discussion: Circular Polarization Vs. Vertical Polarization

Circular polarization is very important for mobile listening. Not all car antennae are vertical and the penalty is up to 20 db if you're not polarized correctly. The difference is only a few dollars to get a ring antenna. This is a great illustration of "penny wise, pound foolish." Your antenna IS y...

Re: Theory Discussion: Circular Polarization Vs. Vertical Polarization

There is a noise penalty when operating in FM stereo as opposed to mono. Yes...a more robust signal is needed for full quieting. But as others have explained, the FCC grants power levels based on separation; you accept the coverage limitations and try to maximize S/N by limiting dynamic range to som...

Re: Theory Discussion: Circular Polarization Vs. Vertical Polarization

The reason television stations have historically not used circular polarization is because most tv viewing is done in a stationary environment and does not suffer from multipath in the same way as mobile radio listeners. Radio listening is a constantly changing environment making mitigation difficul...

Re: Orban FTP Details

The ORBAN site is being moved. This is Day Sequerra we're talking about here...it'll be lucky to get back up at all. Sounds the same way I feel about them after they screwed up the repair of an M2 modulation monitor. After waiting months for it to come back it still didn't come back working properl...

Re: Gates Air Flex20 vs. Nautel NV20lt

They have gone through 8 or 10 pallets at this point and they are always 1 and 2. My gut tells me there is a problem with the combiner. ...Lee What does Nautel tech support say about the same modules failing every time? Do they give a reasonable explanation for why the same two pallets are the only...

Re: Gates Air Flex20 vs. Nautel NV20lt

I do have a bit of a sour taste in my mouth with one of the Nautel VS2.5 installations that I have done and it has, from day one, been blowing PAs. The client has spent more replacing PA modules than they paid for the transmitter in the first place and Nautel keeps blaming it on bad grounding, thei...

Re: Gates Air Flex20 vs. Nautel NV20lt

I work for stations which have both the Flex and GV series Nautel radios. You can't go wrong either way! We have two Flex40s and a FAX20. The FAX has been with us for around 4 years with only a hard to find/replace fuse lost. The Flexivas have been around for 2 years and have never lost any parts bu...

How Often Should You Rebuild Antenna and Transmission Line

A question for the brain trust...how often should you rebuild your antenna/transmission line? Are any of you rebuilding 1000 foot runs of rigid every ten years to replace the watchband springs/o-rings/grease or do you wait for the smoke signal? Antenna rebuilds...every 7-10 years or when they refuse...
