Re: GATES ONE IRF-350 REPLACEMENT

I'm going way out on a limb here, but given their age now, if you have a cranky SX-series rig, you might give the cans a shake. If the caps are over about 8yrs and the TX is not living in a refrigerated hut... Just go ahead and order the cap kit. I have one Gates1 that I am about to change the caps...

Re: Sage ENDEC Printing

Is there a requirement to actually print and store the EAS logs on paper? I keep the Sage emails in weekly folders and keep a separate single-sheet "station log" to sign off on EAS, Tower lights, etc, but don't attach the sage alerts to that log. They are archived in the "EAS" email account. None t...

Re: Sage ENDEC Printing

Not printing at all.... I have quite a number of Sage units at clients and none of them print directly. One was trying to do it via ftp somehow but the big office printer would print a single line per sheet of paper and I just killed the ftp. They had boxes of paper that was their "EAS Log" previous...

Re: National over Eimac or Econco

So... given that Eimac and Econco are both divisions of Communications and Power Industries, Inc (CPI), are they basically coming out of the same factory and, if so, what would the practical difference be? I do not know for sure but assume that the new Econco tubes are actually assembled on their r...

Re: Getting RDS to transmitter

We recently had to switch to a Moseley PCL 610 with a dsp6000 due to some interference issues Did you change channels or otherwise clear up the interference? If not, your interference may still rear it's ugly head in the form of digical burps, squawks and eventually dead silence. And as someone els...

Re: National over Eimac or Econco

Right now, that is what I would do. The YU148 is one of the only tubes that Econco can build new and they seem to have as good of a handle on it as anyone right now. AND IIRC, their price for a new YU148 wasn't much higher than a rebuild and substantially less than an Eimac.

Good luck,

Re: National over Eimac or Econco

Looking for a YU148 tube for use in an Energy Onix ECO-10 transmitter. I know a new Eimac should be top of the line but has anyone had any experience with the National or new Econco. I have been using Econco rebuilds with good results until last time when I had to get three tubes before I got a goo...

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.
I have also heard rumors of a reduction and repack of transponder channels.

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

Here's a chart listing frequencies and polarities on a certain path. One hop is Ku band, the rest is 3700-4200. http://long-lines.net/places-routes/HanoverCS_IL-Lee_IL/CA31120.html Thanks, That helps a lot. Would I be incorrect to assume that most of their links used basically the same C-band frequ...

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

Numbers of receive dishes: That's 16 receive dishes in one small market. I am estimating that there are 15,000+ C-band links in use as opposed to the registered 1500... Estimating (conservatively) that half of all licensed full power AM&FM stations have A dish, several hundreds of LPFM and satilato...

Re: Audio Bandwidth of an AM Broadcast Station

I thought he meant that the entire transmission system was flat to 15 kHz including the audio. If everything beyond the transmitter is flat but he is using an NRSC filter then I agree that it should sound very good. I don't recall the exact post but I think that his antenna was flat to 15khz AND he...

And less crap coming back to the transmitter causing intermodulation products 30 KHz away.

Re: Audio Bandwidth of an AM Broadcast Station

How does it pass the required annual NRSC measurement? Using an SW filter at 4.5khz bandwidth, it shouldn't even approach the NRSC mask. IIRC, the NRSC filters are reasonably flat out to 9khz wide and brickwall at 10 or 11khz. Over the years, I have done NRSC tests on music stations that passed eas...
