One quick one.

Woman during the DTV transition, my old market at a VHF 6, DT 49. When the analog shut down happened, she went to radio shack and bought a "digital radio", so she could continue hearing channel 6 at "87.7", but couldn't figure out how to make it work...

There's this:

http://www.charliedavy.co.uk/surelog-free/

Free version only records at low bit rates and lacks some other features...but if you don't need high-quality audio, can't beat free.

The paid version is about $45 US.

The $45 version fits our budget as well. Thanks for the find!

Any suggestions for an inexpensive, PC based audio aircheck recorder. It would need to be able to take a tally to start and stop. Right now our students use a Denon flash drive unit, which is somewhat kludgey, to do their airchecks. So I'd like to start looking for what the next level up would be....

Good idea. I almost posted it here, but figured it didn't apply to the majority of members who work in radio.

Also the board settings would've prevented you from doing so too. Only admins/moderators can create posts in this forum. We just move the posts deemed to fit in this forum here.

Moved to Engineering news forum.

The only ways for an LPFM to generate revenue are through donations, fundraisers and underwriting because they are non-commercial. Any LPFM that airs actual commercials should be reported to the Commission for violating the terms of its license. Two of the three I mentioned where. Nothing happened.

Then there are the three LPFMs in Southern New England, which are all running commercially, two of which are "co owned" as part of a four station cluster.... The two which are co-owned, supposidly were reported by another radio owners in the state (who himself is running two translators on two diffe...

Back during the transition to all digital TV, we had a woman who called us, after talking to her friend "in the know" to tell us how unhappy she was that we were turning down our transmitters at night to save power. She was so mad she even contacted the local senator's office. Turns out, she had ass...

KOLN-TV's tower was constructed in 1984, according to FCC records. KOLN did not repack.

This should probably be moved to the AM forum.

Agreed, and it has been done.

Three comments: Motor operated circuit breakers are found in UHF TV transmitters employing IOT's (Inductive Output Tubes). The crowbar circuit which protects the IOT throws a dead short on the beam supply via a hydrogen thyratron. This trips the 3-phase breaker for the beam supply located (in the c...

ABB (and I'm sure others) make motor operated circuit breakers.

Motor Operator Breakers are typically only found in machine control logic systems, where breakers are also tied to a shunt trip, and used as a method to reset. They are never found in life or property safety panels.

Reminds me of the photo in RadioWorld magazine's Workbench column that showed a Continental Electronics FM TX circuit breaker being pulled up/on through a rather large externally-mounted solenoid? Seemed like a clever idea but I too agree that you really want to be present when restoring power. Bob...

The old panel box is about 40 years old. I would never want a circuit breaker that I can't reset in person. If something causes a trip, you're not sure, hit "reset", and it comes back, you could be looking at replacing the panel with the rest of the building that burned down. For the nuisance for a...

You want an audio processor for your translator. Trust me on this. The audio processor does more than make your station "sound good", it helps provide modulation density and other niceties that can help reduce multipath noise, offer protection from over modulation and make your station sound like, w...
