Re: possible ownership cap rule changes

Believed this discussion scheduled for a September meeting. Whether it will go to a rule making proposal is another issue. Some of the bigger operators are opposed (I-Heart, Cumulus), while the NAB proposed essentially ending all ownership restrictions below market 75. Believe MMTC and related minor...

Re: FCC Applications ...

Translators not protected against a new application--they are secondary stations. There must be an area near your proposed city of license where a tower could be put up that meets the minimum distance separations in all directions AND would provide 70 dbu coverage to the city of license. However, on...

Re: Anyone Home?

Note the pending rule making to tighten the rules for complaints--e.g. 6 complainants, must be from areas inside the 54 dbu contour of the full power station. Also note that LPFM's must protect translators existing at the time a window opens (and translators, to some extent, must protect LPFM's. In ...

Re: Anyone Home?

WRSB--which has an app to change from 1590 to 1600 with 300 watts non-D-Day (DA-N),--is probably a good example of what will happen with many AM stations. Once the translator is on, it makes more sense to either simplify the DA by reducing power, or even just go non directional day only-since the tr...

Re: FCC Applications ...

You could spend several hundred dollars only to find that there is no channel available in your location. Even if there is a channel, and you spend the money to get it assigned--it may be years before the Commission opens another window. Then you may find you are competing with other applicants for ...

Re: ECO-4, Tuning Information

Was the station on the air before your company bought it? Did the seller own other stations? I wonder if they might have had a newer transmitter there--and just dropped this thing in once they got a deal. Stranger things have happened. If I have time I'll find my ECO-4 book and see what it says abou...

Re: Ecreso vs. BW for Translator

They didn't have a computer on this transmitter--just trying to navigate through the little LCD screen on the front panel. May have been at the first level--but I didn't see it. On a Nautel "X" and "^" switches it on or off. On the Gates Air Flexiva there is an off/on switch. The most important thin...

Re: The eco-4 shivley antenna, with Mystery Ports

Putting on my legal hat--I wonder if they have applied for an STA to remain silent while the new owners makes these changes. A day or so outage isn't a problem, of course. But this project looks like it may go on for a while--well past the 30 days the Commission wants to see an STA for either a temp...

Re: Ecreso vs. BW for Translator

You might want to check SCMS for a quote on a 500 watt Gates Air (unless you need more than 500 watts--then you are stuck with the BW/Ecreso or go up to a Nautel or BE kilowatt. Another option might be the Bext 700 watt, which lists for around $4k. Believe the Bext is still made by RVR.

Re: The eco-4 shivley antenna, with Mystery Ports

Now--if I am confused, and 295' is the coax length at the present installation you just took apart--then this explains the 3" coax. With those parameters, the transmitter power out required is 4,087 watts. Still marginal.

Re: The eco-4 shivley antenna, with Mystery Ports

Houston--we have a problem!!! Compiling these threads, you have a sick ECO-4 and are moving to a new tower requiring 295 feet of transmission line (1 5/8th foam proposed), for an ERP of 3600 watts. Now the antenna is down you see it is a two bay--not a four bay. OK--Antenna gain for a two bay Shivel...

Re: Ecreso vs. BW for Translator

I have three translator tenants on one of my towers (plus a short-spaced Class A). Two of them use BW transmitters. One BW--just 3 years old- has already been sent back for repairs. The other is brand new...we will see what happens. Wasn't impressed with the BW when we had a climber on the tower & h...

Re: Inside the ECO-4

There is a flexible metal plate in front of the tubes with a bunch of holes drilled in it. If you take off that black cover on the front of the transmitter you'll see it. The book--if you have one--should tell you how many holes down it should be connected for your frequency. If that is attached at ...

Re: Additional Info on ECO-4, new feeder, Shivley 6813

OK, your required TPO--using the Shively 4 bay antenna and the 1 5/8th foam line--is 1,980 watts. Is this the new site or the existing site? If it is the existing site, for the 3" line--the TPO (surprisingly!) is 1,900 watts. Since the foam line is rated for 8 kw, there really isn't much point to us...

Re: Recommendations for Feeder Line, ECO-4, Shivley 6813

Should have read this thread before the one about the output power. As I mentioned in the feedline thread--read the rules first about changes to the transmission plant to see if you might need to get a cp first. I would add to this discussion that we should figure out the numbers you need at the new...
