Re: Tower needed

It boils down to a tower designed for the weight and wind loading characteristics for the environment it will be located. For example; a tower located in the desert near sea level with light winds will require less structural elements than a tower atop a 4,000ft mountain top site with freezing fog o...

Re: Audemat FMB80 RDS and RCS..

It's been a while since setting one of these up, but generally you'll need a PC running some form of middle-ware application between what your automation spits out, and your RDS encoder. Allen Hartle at Jump2Go is the guru on making really good interfaces for RDS. I've always used his applications f...

Re: Harris HT30 issue

So this HT30 is randomly shutting down. Sometimes with no faults, other times with other random faults. No two times are a like (not the same fault indicator twice). After it shuts down, it attempts to restart a couple of times, then it will reset, and flame up like normal. You can apply the Plate ...

Re: Bad hum

As low-tech as it sounds, the tried and true troubleshooting always pays. I would: Start at the transmitter site. Disconnect the audio input from the STL to the transmitter and look for the noise to go away. Goes away? Then go to the studio and disconnect the audio from the transmitter STL input. No...

Re: Backup STL link

If you're just looking for a backup positive way to shut off the transmitter, why not use the squelch contacts on the STL receiver and connect it to one of the transmitter external interlock connections? Shut down the STL transmitter and off goes your broadcast transmitter.

Re: Static Dissipators?

Agree with Mark, there may be something to Static Cats or other spine-ball devices, but it's hard to document. Most of these devices are installed on top of the tower, but that doesn't stop other parts of the tower from being struck. That said, I can't think of a tower which uses some of these devic...

Re: Wheatnet vs AXIA

We're using Axia and Pathfinder to great success with our six radio studios. We steered away from Wheatstone, mainly because we experienced a poor customer support with one of our big TV consoles. My impression: Wheatstone has a lot of blinking lights and graphics, but the overall construction seems...

Re: FCC fines two operators run a LPTV 18 years after expiration

Just the simple fact that it took the Commission 18 years to notice and act? Speaks volumes.

Re: New Sound Board

Why not just fix the headphone amp? I'm sure there is someone around with basic electronic troubleshooting skills and a good soldering iron that can repair it. $100 vs. even $1,000? Seems like a no-brainer to me.

What is the make and model of the console?

Re: Emergency communication

Thinking from the emergency communication aspect a ham license is almost a must if you maintain sites that have to work in all situations and you need to communicate with other engineers. Provided you didn't communicate via amateur radio with other Engineers about business-related issues. For examp...

I believe you have to move up to RCS Zetta, for their remote voice tracking option.

Re: IP streaming of multiple satellite tv channels

What is your resolution/quality expectation? Not inexpensive my any measure, but there are several brands of IP video/audio encoders that will give you the ability to IP stream over the public Internet. The good ones will cost you $60,000 USD per channel, per stream, but they're professional grade, ...

Just curious why you're hung up on SMPTE 2022 as a requirement? We use off the shelf IP encoders from Fujitsu and Harmonic from several of our overseas bureaus using VPN tunnels over the public Internet with great success. Much less expensive, higher quality, and lower cost than satellite by any mea...

Re: RBDS Phase

Yeah I've never heard about dealing with phasing of RDS. As everyone else mentioned, it's pretty much: Mount device, plug in power, connect to exciter, audio processor, or loop through composite audio. Insert external data as available, set injection level, done! Next, go have lunch at your favorite...

Re: High Pitched Tone in FM Audio?

Now that you've got the exciter issues in hand, you may want to check for AM noise next. If you don't have one available already, see if you can get your hands on a newer Belar or decent modulation monitor that measures AM noise. That transmitter-exciter combination all tuned up, should see AM noise...
