Re: Omnitronix 1kw vswr sensitivity...

Omnitronix set those up to dump off the air if a hummingbird passes gas 16 miles upwind. I actually had guessed that it was closer to 20 miles... I suffered the trauma of a 2.5 for several years. It is still on the air but maintained by someone more willing to spend their days waiting on it's next ...

Re: VSWR what is safe?

I would consider reducing power by about 3DB. This would reduce the stress on the antenna and transmission line, and would be barely perceivable to your listeners. The station management may object, but try to explain that the reduction will have minimal impact on coverage, but is a way to try to m...

Re: VSWR what is safe?

Some transmitters are more tolerant of VSWR than others but I think that 1.5 is getting pretty close to max for most. Your statement about having to bump the vswr OL up some is an indicator that it is on the border line. Your tube life and self induced multipath will certainly be impacted with that ...

Re: CRC spray bad for Carbon Faders?

If they are P&G faders, a good cleaning in soapy water might be all they need. You will have to tear down to where you can see the faders themselves to be sure. There is a paper floating around (no pun intended) on properly washing P&G faders. Cleaning P&G faders with chemical spray doesn't automati...

Re: just now pulled the trigger on a Communications service monitor

If it works as advertised, I would have to think that it is a pretty darn good deal. I bought a nice IFR1500 several years ago for $2.5k and that was a good deal then. IFR1200's were considerably more expensive then due to being substantially smaller and lighter.

Re: Make FM Sound like AM

Imagine the horror of a young country client upon finding out that an Urban preset was their favorite. Lots of bottom end, good crisp vocals. Don't let the names scare you away from a good starting point. It was quickly renamed and slightly modified to something else but stock, it sounded good on th...

Re: TP always on RDS?

He says there's more chances of people stopping on our station while on automatic search with their car radios. And when there is no traffic info they'll just push the scan button again and just assume the station is inept. I have a bunch of stations running various levels of fully dynamic and basi...

Re: Harris HT 3.5 FM - Factory Tune-Up Data Sheet

Tried the IPA failure, it's not that. Thanks, however. We had once, in the past had to do that, and it sure is handy. Looks like it's that odd 'screen' situation, and tracking down the cause. Assuming that you mean IPA bypass for the purpose of my comments... What is your exciter drive to the IPA? ...

Re: Energy-onix Pulsar 5000 manual? and Parts?

I have two 1k Pulsars that were spurious right from the factory. Under what conditions are they dirty? I have 1ea 1k Pulsar but it has always been as clean as anything on the market. It always passes NRSC at 1kw and 44w. IIRC the 2nd,3rd, etc harmonics just barely pass but they are the same every y...

Re: Broadcasting worksheet ( schedule for the day ) :?:

It is called a log or traffic log. Natural Log and Natural Music are the software that most of my clients use but there are lots of others. Some are horrendously expensive and there are probably some open source. If you are using automation, all of the modern traffic systems should export a log that...

Re: VOIP lines w/ Tele Interface

I have several clients running a variety of digital and analog hybrids on various VOIP services and haven't had any complaints thus far. Digital codecs (BlueBox, etc) do not function reliably on VOIP but the on-air hybrids don't seem to notice the difference.

What are they doing?

Later,

Re: Inovonics 235 schematic

Ebay is a crapshoot at best. True. I am sometimes willing to shoot craps if the price is right, but that is seldom the case with broadcast equipment on eBay. I emailed the 235 seller but never heard from him - that alone is sufficient for me to rule out bidding on an auction. I am the same. I have ...

Re: Replacing Harris Aurora 5800 Lan/T1 radio

The station bought a pair of Ubiquity Bullet-M units, plugged them in, configured them for DHCP, and got a received signal level of -73dBm, very close to the predicted value. Both the studio and transmitter equipment seemed to be quite happy with the setup and everything is working just as it did w...

No short in transformer. Ohms out fine. Transformer is fine until I connect B- to ground then bam blown 35a fuse! Removing the HV positive directly from the rectifiers doesn't clear it? Might try leaving the neg connected to the rectifier and take the neg loose at the Ip meter to further isolate co...
