Re: Tower needed

Translation needed? I assume by "cement block" you mean a block of cement in the ground--not a couple of masonry blocks like you would use to build a building? Part of the tower design usually specifies the size of the guy anchor system, which consists of a steel rod with a closed loop where the wir...

Re: Omnia FM HOT OS

Here's a picture picked up off the internet: http://www.dtsbroadcast.com/1172/45/ex-demo/omnia-hot-sefx-detail.html I had two Omnias similar to this, vintage 2000. Came with a station I purchased. When they worked they sounded good. However, both developed memory problems--they would forget what the...

Re: National over Eimac or Econco

Local station had to borrow my VS300 for a couple of weeks because Econco didn't have a tube in stock for their Harris 3.5K. Had to wait while they sent in the tired tube for a rebuild by Econco.

Re: Sage ENDEC Printing

Both our Sages are at the studios, and are on the internal network. So the simple solution is bring up the Sage on a browser and print out the log pages on a networked printer. One printer is a Xerox Phaser, the other a little Brother laser. No problem. I did discover that Chrome works best for prin...

Re: National over Eimac or Econco

Been no real problems with the NV-lt. We had one pa amp fail early on (under warranty). Pulled the module out--transmitter dropped down to 5 kw, put the module on the bench made about 5 solder connections for the new module, popped it back in & the transmitter went back to full power. I don't rememb...

Re: National over Eimac or Econco

On that note--I have three tubes from a decommissioned Harris 10K. One had about a year on it when the IPA tube socket died, one pulled at 80% power, & one unknown condition. Make any reasonable offer--only have one shipping box, though. In WV. Also have the plate transformer from that 10K--stored i...

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

That's what we are talking about--proposal for terrestrial shared use with C-band down links floated by FCC Commissioner O'Rielly.

Nothing concrete beyond that except may include "mobile" uses.

Re: American radio Journal

Well, not on this list. But the folks at RevFM in central Pennsylvania were very helpful in recovering the missing reports.

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

The primary purpose of registration was protection against changes in terrestrial microwave links. Since these were fixed path links--usually using massive self-supporting towers (or even those concrete towers), the only dish owners who would need this protection were those: A: With a dish right nex...

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

Numbers of receive dishes: Market #249, Parkersburg-Marietta. One TV studio with three on-air channels (NBC/CBS/Fox). One cluster with 6 stations, one with 4, EMF outlet, NPR state public radio, and two other 3 station clusters (one is mine). All have satellite dishes. Just off the top of my head--w...

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

The point-to-point terrestrial microwave and C-band downlink transponder frequencies were set up so that they were interleaved with each other. Since this provided some isolation, as long as your dish was not directly aimed at the TI, the use of some kind of shielding would allow the dish to work. I...

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

Or the @#$%^ regulatory "fee"?

I calculated that I pay 4 times per 12+ resident (Arbitron 12+ pop. figures) in my small market (#249) what KDKA pays per 12+ resident in the Pittsburgh market. KD gets considerably better rates than I do.

Re: band pass filter recommendations

What will help is the relatively low powers of the translator and station--103.9 750 watts into an old Collins 3 bay, 250 watts into whatever antenna the tenant plans to use. The transmitters will be new--VS1 and a 1 kw Gates Air Flexiva.

Re: FM translators of AM stations

Expect a number of those remaining AM stations without translators to vanish in the coming years (except for the 50 kw stations). Also, I would suspect that many of those stations are already dying--on long-term STA's, reduced power, long wires, off-air, etc.
