Re: BE AM 1A Power meter not working in FWD

Doesn’t reflected read on a separate meter on the AM-1A? I am familiar with only one of these which was installed in 2003. The top meter reads forward power in two ranges selectable by a switch whose third position is OFF and is the position we generally leave it in when thru with it. I don’t think ...

Re: BCST ELECT MVDS SYSTEM

Got a 35B with one. The monitor has just recently lost its mind and displays what looks like an analog TV picture with the horizontal hold not holding.

Station is being sold so it will likely be someone else’s problem/project.

Re: Tomato Soup Incident

It wasn’t in the dryer long. :roll: It will work; it just won’t shut itself down or has something else going on that drains the battery.

Re: MDCL or something wrong?

I believe the idea is to reduce the amount of power needed during peaks of modulation. I don’t have direct experience but our company has several in use in other markets. They have done drive around tests and report there is no perceptible increase in noise level during those points where the carrie...

Re: Tomato Soup Incident

So this begs a question. I had a similar electronics-drowning incident where I left my car key/fob for my 2012 Fiat 500 Sport in a pair of jeans which I washed. Didn’t notice it was in there until it announced itself in the dryer with all the banging around it produced. (There were some other items ...

Re: Tomato Soup Incident

I wonder if the soup is/was less toxic to the PC board than the incident I heard, which was when a jock dumped a large orange juice into a PR&E BMX console. Took out the entire backplane and then some. Luckily it wasn't at any of my stations. Coffee can be quite toxic to BMXs as well, as proven by ...

Re: C-band TI

In the early 80’s a Scientific Atlanta broadcast installation in Omaha used an LNA with a downconvert to 70 MHz after feedline entered the building. The downconverter was inside the receiver and was I think a double conversion to get down to 70. So there was some of that stuff in the broadcast realm...

Re: Full-Time Engineering Opening--Charlotte, NC

One can go to the main page at bbnradio.org and the Minustry Opportunities link in the menu. Scroll down to the bottom of the page to the button that opens the application form. Network Broadcast Engineer is one of the choices.

Hope this helps.

Re: Dealing with mixing products

Not too surprised at the size of the filter. I have a 70kHz space between a 5kw and a 1kw here. They are about a mile apart, too. The 5kw fundamental gets into the 1kw and mixes with its 2nd harmonic producing a difference only another 70kHz away from the 1kw in the opposite direction. This is perha...

Re: Transmitter Nitrogen Issue

Well, you don’t have to service a dehydrator if you use nitrogen. You won’t burn up a dehydrator on a leaky line with nitrogen. You won’t soil your underwear when the dehydrator fires up (I just do not ever get used to that!). There are probably better reasons. I think one thing to try, if you haven...

Re: RX-only C-band receive station registration, form 312

I recall that happening but don't recall the exact situation or circumstances. Do you remember when it was, what it was and which commissioner it was? I’d have to research the name(s). I recall it was a male commissioner who used the Repeater directory, that UPS was the intended beneficiary to be a...

Re: RX-only C-band receive station registration, form 312

I don’t know if it would make a hill of beans of difference but perhaps a reminder of how in the not-too-distant past a commissioner whipped out the ARRL Repeater Directory to “discover” there was no operation below 222 MHz so surely we wouldn’t miss the spectrum, might be worth pointing out. This i...

I don't know how EMF thinks on backup. They run naked all of the time anyway with only one transmitter and no generator. They were off the air for a whole week when they had transmitter trouble a couple of years ago. ...Lee When K-love is off the air that’s when the $ come in from listeners in that...
