USB Keyboards/Mice for Studio

Any suggestions for good USB keyboards and mice that work well in a studio application and stand up to jock abuse?

Re: Blue tooth mixer and high school games

We try to avoid cell calls for ball game feeds as much as possible. Typically we use 4G IP with a smartphone tethered to an old router that I flashed with openWRT, and then connect a Tieline Commander to the router via the Ethernet port. Since we are in a fairly good area for cell coverage, we usual...

Re: BE AM-1A Power Supply

If you cycle the front panel breaker on and off quickly a few times the bad supply will sometimes restart and run until the power blinks again. I have had about 50% success with this. I now keep a spare PS in my truck (one of the few spare parts that I carry these days other than a spare LNB). Inte...

Re: BE AM-1A Power Supply

Ya sure, you betcha! That's the one. Look at it carefully and you should see a couple of screws on the metal cover. These screws go into mretallic standoffs. Pull those screws from INSIDE the controller enclosure, not outside. That will reveal the power supply in all it's "living color". The rest i...

BE AM-1A Power Supply

I have a sick AM-1A that has the infamous flashing light syndrome on the controller. I'm familiar with the cause and the replacement off-the-shelf supply (or poaching of Starguide supply) but since I have not done one of these replacements before, wanted to confirm that this supply is the one locate...

Re: The high leg

I saw someone tell a story on one of these engineering groups about an electrician wiring the outlet for a break room Coke machine to the high leg...with the expected results. I seem to remember here at the office they had to stop an electrician from tapping into the lighting circuit since it was 277.

Re: Women Hearing Distorsion on Station After STL realign

That does seem very low. If I am remembering correctly, the manual says it wants to see 40 dBuV for good mono performance, and 50 dBuV for stereo. The LPFM I take care of used to run one of those, and I think we usually saw > 60 on it, but it was for a path of just under 2.5 miles. I assume you've t...

Re: Wanna Play "Guess What's in the Grey Box?"

TFT EAS 911s do not have audio in/out. That's in a separate box, either TFT's or your own home brew. So perhaps this is that. The LPFM I take care of used to have a home brewed interrupt in a brown metal box for this very reason. The TFT 911D they had didn't come with an interrupt relay. It was ret...

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

I'll have to ask the one place I moved what it does. I was able to get about 11.5 on Westwood and a screaming >15 on Premiere after the move. Their Westwood was doing a 9.3 before moving, I think there may have been a tree slowly growing into the view of the dish, so the move was probably a good thi...

Re: More Bad Sports Audio on Fox

I agree on the Shure mixers. I used to carry a 267 mixer for high school games. Currently I use a homebrewed rack built around a Shure SCM810, which also has the switchable limiter and remote on/off/mute logic capability, so I was able to build some handy cough buttons into the front panel next to t...

Re: LPFM Antenna Recommendations

I called ERI with a few questions on the 100A and did learn a good tidbit that I thought might be worth sharing. If you do get a cracked tip due to water, lightning, or whatever, here's the replacement. https://www.menards.com/main/plumbing/rough-plumbing/pipe-tubing-hoses-fittings-accessories/fitti...

Re: LPFM Antenna Recommendations

Interesting to hear that some folks are using the LPX series on translators. It seems like overkill for the power level, but I do like the idea of a sealed antenna. Does it need to be pressurized? This station is near the middle of the band at 97.3, so a "broadband" antenna would probably work. Howe...

LPFM Antenna Recommendations

An LP I take care of recently had the antenna mounting scheme changed to get some separation between the bays and the tower face. In the course of this, the bays were lowered to the ground and I had a chance to inspect them after ~4 years out in the elements. The antenna is an ERI 100A model. One ba...

Re: ETRS Reporting Forms 2 & 3 09/27/2017

It seemed like a total crapshoot for me. CORES wouldn't work in Firefox (had to reset password), then ETRS wouldn't work in IE or Edge.

Re: EAS Antenna Issue

Still, reality must intrude. My primary monitoring assignment is a Class IV 25 miles away....because the state plan has never been changed to reflect the real world. I just monitor the FM relay, a Class B. Another non-com station isn't even in the state plan (it's 900 watts, been on the air since 2...
