Re: Transmitter Nitrogen Issue

...I'm thinking of coming out one night and turning my RF off and taking a look to see if any pressure windows are gone on the waveguide on the ground... I'd do a bubble test first before going through all that trouble. Also, is that tank chained to the wall? On my way to buy bubbles now, it is not.

Re: Transmitter Nitrogen Issue

Do you have "waveguide" or coax. Waveguide is presurrized at a very low level with a high flow dehydrator. Coax can use nitrogen or a dehydrator. If you have waveguide there are pressure windows that are easy to blow out and cause a massive leak. Please confirm what type of equipment,, send photo. ...

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 wh...

Re: Transmitter Nitrogen Issue

And as stated which is the most confusing to me (it may not be as confusing to someone with more experience) is the fact that pressurized air is pushing back out from the waveguide to my regulator. Let's suppose you're pressurizing 1,000 feet of 3-1/8" transmission line... that line has a volume on...

Re: Transmitter Nitrogen Issue

Whoops! Just remembered another issue. We had a site where the tanks were going empty pretty fast and found the leak was caused by a bad fitting that attached the regulator to the nitrogen tank. Check that fitting to see if it is grooved, or deformed. Don't over tighten as the nitro tank is steel, ...

Re: Transmitter Nitrogen Issue

Thanks, I will do that. Although if that were the case wouldn't you think when I remove my nitrogen cable from the waveguide I shouldn't feel pressurized air coming back out?

Re: Transmitter Nitrogen Issue

Im on my 3rd nitrogen tank, I recently purchased a new regulator for the tank, from that regulator I goes through a 4 output manifold kit, all are closed except the gauge connected to my wave guide. I have been setting the regulator to show around 4 PSI on the manifold kit gauge that is connected to...

Transmitter Nitrogen Issue

Hi, I am somewhat new to using a nitrogen solution on my RF line. I have a system where the nitrogen is pumped into my wave guide for my transmission line that goes my to antenna for OTA. My nitrogen tanks are empty within 2 days of connecting them to my system, I'm trying to determine if I have a l...

Larcan TTC XLS-1000

Hi, Is anybody familiar or have a manual for the Larcan TTC XLS-1000 transmitter by chance? I currently have a location down which houses the XLS-1000, I have had no luck finding a manual online and I have been in touch with Maple Leaf, they pinged me out to Blue Sky RF in Colorado but I have not he...
