Thanks, Chuck. Appreciate you thoughts.

Another Windcharger questionn

So... One of my clients has just added some stations to his group. One of them has a 190 foot Windcharger, possibly vintage '47. This is one of two that I now have within the groups I take care of. The other is a 350' stick that's been reasonably well cared for and, though the tower guys don't like ...

Re: Ecreso vs. BW for Translator

If you're looking at a dollar vs problem ratio, then Nautel is your obvious choice. If you're looking to spend less and might not be so "mission critical", then I think BW works out very well. In my travels, people buy BW because they don't have the budget for a Nautel... either that, or they were c...

Re: Anyone Home?

Another "stretch" of the ID requirements that seems to be prevalent in my state, is to have a news break at :15 and :45 and put the "legal" station ID there, even though they have a two-minute commercial break at the top of every hour, where they throw in a promo... Bob M. That does stretch the mea...

Re: Transmitter plant ambient temps?

That said, what temps do you guys like to maintain in your buildings? lower 80s for solid state transmitters. mid to low 70s for tubes. I also put temperature sensors at every transmitter site that starts calling out when the room temperature reaches mid 90s and starts shutting stuff down via macro...

Re: Wavering field intensity

That probably explains why this site has been an interesting topic around here, but has never really concerned anyone.

Re: Wavering field intensity

Maybe a bit off-topic, but something to be aware of before you go out to do the monitor points. You've probably seen the one with a freeway running between the towers. This is one of my client stations in Eastern Washington. 3 towers in this one and yes... the tracks were here first. Don't know why ...

Re: DX-10 Controller Probs

Bringing this forward, because one of my DX-10s bit the dust this month with the same symptoms. In my case, the problem was the caps, which were past their expected life anyway, but didn't appreciate being cooped up in a room with a recently-failed air conditioner. A couple of weeks at 120 degrees p...

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

You're right.
My meter's bad, but the scenario doesn't involve REF readings.

Got on the keyboard before coffee this morning. :roll:

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

I serviced an AM-1A this week that has a power meter that will only go up to about 800 watts. At that point, it hits a wall. You can tap it and move it around a bit, but it pretty much jams at that point. Base readings indicate the transmitter's OK. By contrast, under normal circumstances, the ref s...

Transmitter plant ambient temps?

I think this may be covered in an earlier thread. Feel free to redirect if you know where it is. I'm currently dealing with a repair crisis, where a failed AC unit allowed a DX-10 to operate for several weeks in near-100 degree temps. That appears to have resulted in the final assault on already-age...

Re: STL Frequencies

Hey Chuck: The brand is Ubiquity. My friend said there is one in use in relatively flat terrain providing high speed internet at a path distance of around 12 miles. Fossil I've used quite a bit of this brand, though not yet their model with the farthest range. Generally, they've been surprisingly r...

Re: A bit of AM History

Geez.... at least use cart labels over Scotch Tape... or the like!

Most of the owners I worked for would have freaked if I'd done that to their rigs :-)

Re: GATES ONE IRF-350 REPLACEMENT

Not all IRF350's are created equal. Some are Chinese knockoffs do not hold up under power. If you have IRF350's failing for unknown reasons, better check the manufacturer, could be they're the cheap knockoffs. I've bought IRFP350s from several outlets, and for prices ranging from about 80 cents to ...

Re: Sage ENDEC Printing

All of what Chris suggests works very well. Some time back, I set up the Endecs I watch to FTP alerts to a server at my office. The FTP software routes the received alerts to a subfolder I keep for each station in my circuit. I do that mainly for backup and troubleshooting purposes, and because it w...
