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...

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...

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...

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...

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...

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,

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.

I have heard rumors of a repack of C-band spectrum? Anyone have any thoughts? I have heard the same rumors and have included that exact question in my list of questions for an article. I have submitted my list of questions to Commissioner O'Rielly's press attache but have not received a response ye...

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...

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...

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...

Less mud and grunge from overdriving the highs.

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

Yep...

If you're a phone geek, this link will be a colossal time-suck. :D Isn't that the truth. I spend a couple of hours digging thru the site and learned the name of several local sites that I have seen all my life and a few whereI have worked on 2-way and FM equipment. But never found a single mention ...

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...
