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...

Re: NexGen for home use

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, ...

Re: smpte 2022 vidéo over IP network

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...

Re: High Pitched Tone in FM Audio?

It's probably the exciter, (known problems with the Digit).

Re: Z 10 rigs

I've been pretty successful repairing them on my kitchen table. The output transistors are available from the Philippines for about $30 each from Alibaba.com. A large soldering pencil and some solder wick and the blown transistors are easily removed. In spite of just one transistor being blown, I ha...

Re: How Old is Old?

As I remember, the reason they used to use watchband interconnecting bullets were supposedly the watchband segments conformed better to out of round center conductors caused by uneven extrusion of the copper. The downside is exactly what you found; the watchband develops high resistance over time as...

Re: FM Composite isolation

I've used an analog video DA to split composite audio feeds to more than one exciter with good results. Just use a professional one, not a consumer version with RCA connectors. I've had good luck with the ESE brand DA's. That will give you pretty good isolation and will help make up losses over long...
