WWPN, Westernport, Maryland had to move their studio site when a line of windmills was built on the path between studio and transmitter site.
Those whirling blades didn't help 950 reception.

Remember the V-series Nautel FM transmitters? Had a 2.5 made up of two V-1's and a combiner. The combiner had a hole cut in the back for an RJ-45--but no connector. One of the many times the system went down had a combiner problem--mouse got in through that small hole and set up his apartment inside...

One of the problems with solid state transmitters is air flow. I have a pair of Nautel V1's that--when they worked--had constant problems with heat because of inadequate ventilation. The last working one had to be run with the covers off (usually on the floor--it was relegated to back-up use on loan...
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...

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...
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...
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...
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.
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.

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 ...

Guessing--but looks like simple bcd setup. Going from Right to Left the first bank of switches--marked 10 mhz. --put the switch marked 8 down/ to the(-) position. 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...
