Re: Compression Question

Also.... Watch overall levels when recording. My rule of thumb is to keep voice peaks about 12 db below maximum. You can then do some normalization after the show is done. However, the waveform should not look like a solid black bar when you get done with the program--like you see if you rip some of...

Re: Am I a possible engineer candidate?

Keep the state job--do some contract work for small stations. State pension & insurance something you probably can't replace going private sector. No problem with your qualifications--just the career opportunities available in a declining industry. If you would still like to get some experience on t...

Re: C-band TI

Microwave filter makes a good AWACS filter. We've used hard ware cloth (looks like heavy window screen, made of metal) as shielding --but that was to protect against back scatter from a nearby MCI tower behind our dish. Hardware cloth is often used around gardens to keep rabbits out. As I recall, th...

Re: STL Frequencies

We have a pair of Bric Links with the switchboard software. Don't need static IP addresses--if connection gets broken they reconnect through the switchboard server. The cost of the Bric Links is about the same as the cost of a refurbished STL-10. Used them on a weekly scoreboard show during football...

Re: STL Frequencies

Translator on one of my towers is fed by a Ubiquiti unit on 5 ghz high band. The transmit is at 800 feet AMSL on their STL tower, the receive is about 100 ft (or 1100 ft. AMSL) on my tower--short path, about 4 miles. They use Barix exstreamers on both ends.

Re: STL Frequencies

Section 74.431 (H) allows temporary use for a program link in an equipment failure or other emergency that disrupts the usual STL. As noted, 74.432 provides further exceptions for Alaska, Hawaii and Puerto Rico.

Re: RX-only C-band receive station registration, form 312

Look at the Monday daily digest--has notice regarding this matter. Comments due May 31. Here's what my state association got from the NAB on this issue: We completely understand the frustration and the importance of the C-band for content distribution. The unfortunate reality is that some amount of ...

Next bank, marked 1 mhz.--the number 8 switch also down. third bank--marked 100 mhz.--the 2 switch down and the final bank of switches ar...

Re: Identify mic types

On some of the condensers you can see the element behind the screen==has a more "open" look than the dynamics. Wind screens on many dynamic mike are a much finer mesh.

Of course, many are marked as condenser mikes. Then there is always Google--make and model number look-up.

Re: Contact Closures: Barix and Comrex Access

Best I can figure out you want to have a computer generate a low into the Barix so it can then click it's internal relay to do something else Look at this site:

They have various gadgets that make more sense than tying up the Barix--

Re: Contact Closures: Barix and Comrex Access

I'm confused, but normally you would use a momentary closure to do one action, then a second momentary closure to take a second action. Also, you would need to use a Barix to respond to another far field Barix, and an Access to communicate to another Access. Not sure how the pots circuit factors in ...

Attn Harris FM 10K users

Spring cleaning. I have three 4CX10000J finals used in the Harris 10K. One removed with about a year's use (the IPA socket blew up so we ditched the transmitter for a Nautel), two marked "80%." Only two boxes, though. Pay shipping and they are yours. Otherwise junked. Need to know by the end of the ...
