Re: Over-powered translator

The are all running legal power, but get out extremely well. What the coverage map says Vs, actually coverage can be a big difference and still be legal. The coverage map only depicts the artificial protected service contour, which no radio has a concept of; it's just an allocation tool. You may ve...

The problem with all of this is proving it. FIM-71 readings from the ground are pretty meaningless.
Drone measurements are fairly accurate. The convergence of UAVs and SDRs have made relative pattern measurements fairly easy.

Re: Over-powered translator

If you have a field intensity meter handy measure the FX in the major lobe at around 1-2 miles and then another station at the same distance. The near-field propagation should be similar and you can directly compare the measurements to get a rough idea of what the actual ERP is.

Re: Pirates captured

Arrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

I have a difficult time taking this new-found enforcement backbone seriously when there are so many licensed stations operating illegally that they conveniently ignore. Those cause far more interference than your average pirate.

Re: Continental 816R-3C IPA

In the nearly 50 years that I have been in broadcast engineering I have made mistaken assumptions about a problem too many times. I may or may not have spent the better part of two hours troubleshooting an intermittent ATU network one night only to find out a bug had crawled into an arc gap and low...

Re: LPFM Antenna Recommendations

Two antennas, same site, same transmitter models, same transmission line type and lengths, frequencies are about 2.5 MHz apart: ERI 100A: VSWR is 1.06 Nicom BKG77: 1.32 Both are "out of the box" installations. I really don't have an issue with the Nicoms but you'll want to consider how much it will ...

Re: ESPN3 streaming parameters?

Just logged in and let it run for awhile and did not encounter any issues. I don't have the ability to drill down into the stream specs other than what their player gives me, which is attached. Maybe it'll help.

Re: New member - LPFM transmitter recommendations

We recently had a station in our city get a NOV due to using a non-compliant transmitter with their translator so this is something the FCC looks at. Translator transmitters only have to be type approved which is a different process. I would suspect that translator was spewing garbage which is why ...

Re: Source needed for a few misc parts:

They have the side-wiper parts? Cool.

Yeah, if you don't catch Dan when he's in, you won't be ordering. Part of his charm. ;) I've had decent luck faxing a list of what I need and he usually gets back with what he has the same day.

Re: V & H antenna radiated power

ERP is calculated in the horizontal plane regardless of polarization, at 0°from horizontal. That's often a point of confusion. The vertical plane is usually an entirely different pattern depending on the number of bays, etc. FM stations are licensed for x ERP horizonal and/or y ERP vertical polariza...

Until towers can erect themselves, networks can plan themselves, antennas can mount themselves and electronics can install themselves, there will always be RF engineers.

Re: looking for review of dbx 266XS

First off, in this application you get what you pay for. Nothing in that price range is going to do even a passable job controlling levels for something like this. As mentioned the 266 is a mixing tool, not a mastering tool. Can you set the input to the recorder to -10 when the board indicates 0? Th...

I sent them a message several days ago with 3 simple questions about the VS300 and no one responded.
How did you send them a message?
