Re: BVH-2000 stuck on "INITIAL"

While digging around I did find this:

Re: Tomato Soup Incident

It is often easier to ask forgiveness than permission. Especially when mice are involved. :lol:

As they say in the political world... The coverup is worse than the crime. Especially when Connie finds the dishwasher strainer stopped up with wire markers, electrolytic wrappers and mouse turds.

Didn’t notice it was in there until it announced itself in the dryer with all the banging around it produced.
Which I suppose had heated it up pretty good? I'm guessing if so, the tiny little SMD components have changed value and washing it out won't fix it.

I have ran various contaminated circuit boards thru a cycle in our dish washer. Most of the time it works, sometimes not.
"sometimes not" meaning I get caught. :lol:

Re: Compression Question

I'll 5th or 6'th it... heavily processed audio stuffed into a radio station processing chain drives it nuts. It will look for "something" to do, even though the audio is already compressed and limited..and that "something" isn't often pleasant sounding.

Re: Transmitter plant ambient temps?

Needless to say every piece of solid state equipment inside had died. The only equipment to survive a transmitter shack fire some years back were a pair of marti STL 10 receivers. No idea why. A/C is rare in transmitter buildings up here in central WI, and many do not have heat either. Used to rely...

Re: C-band TI

Yes... Fairchild Dart 384. It was the better receiver of the two IMHO, you could change transponders with a thumbwheel, the SA required you change crystals. A lot of folks made a reed relay crystal switching contraption to allow for changing SA transponders. SEDAT was actually an upgrade for these r...

Re: Am I a possible engineer candidate?

I can't add a whole lot to what TPT already said and I agree with all of it. Unless you are in a large market, the pay is often bad, the benefits do not exist and the hours are awful. We do it for love, not money lol. Perhaps that is fine with you. If so.... SBE membership and certification is nice ...

Re: C-band TI

The Microdyne receivers had a 70 Mhz IF as well.

Our 1982-vintage UPI and NBC audio dish was 70 MHz second IF. Was kinda fun to tune around on the SCPC carriers with a comms receiver and listen in back then. :)

Single channel not a good solution as I need three different transponders, 1, 17, 21
You can install a tuned filter to notch out in-band interference, as long as it doesn't land on top of one of your transponders.

Re: STL Frequencies

These days my Paul Bunyan imitation consists of eating pancakes. Preferably "all you can eat". :lol: Trees have been a PITA with the 950's too. Had to put up a power pole at one site to get over a row of pines, moved the receive dish 100' up the tower at another for the same reason. Now another site...

Re: STL Frequencies

This is such a short path that you can see clearly one tower from the other. Problem is it's over a fairly industrial area
and interference worries me with unlicensed stuff. The other alternative is using public internet with Barix boxes, but that's another set of possible issues.

Re: STL Frequencies

Well there goes that plan lol.
This would be bringing program audio from one transmitter site to another transmitter site to feed an FM translator.
That's pretty clearly not "TSL" use.

Can a 450 Mhz RPU be used for STL duty legally? Not temporary emergency use, but full time?

LM34 (lm35, lm335Z, etc) will do it for about a buck fifty.
