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...

Re: Harris CD Link

3. We removed both the RX and TX to be evaluated by Harris but quickly learned that they are now charging $2400 EACH flat rate repair. The owner immediately said that he would buy a new composite pair before spending $5k on repairing these. Wow. Just, wow... :shock: And they wonder why no one wants...

Re: Starlink LAN

I am fascinated by this as well. How did you go about getting the Ubiquiti radios to work without cross polarization? I thought the way Ubiquiti did duplex was to send and receive on the same frequency but on the other polarity (ie: TX-Horizontal, RX-Vertical). I would love to buy some cheap Ubiqui...

Re: Starlink LAN

Not here...we diplexed in some Ubiquiti 900 MHz radios for a 2-way data connection. RDS and remote control is all on that. The main audio is still on the Starlink.

Of the six sites I've been at regularly, I've never seen a dead bird. Just dead rodents in traps and a snake skin or two.

Re: CenturyLink Question

Sure enough, according to the repair man who came out, it was rodent damage. Squirrels got into a pedestal somewhere and chewed wires. He also said the insulation on the lines on the street is in terrible shape. I've told the owner that even though we got this fixed, it's not going to fix the packet...

Re: Barix levels

The AM translators are on Tieline Bridge-Its using their "music" algorithms. They sound awful, IMO, worse on music than speech ironically, and sometimes break into chattering briefly with packet drops. Usually not longer than a syllable or two. I would like to try cramming uncompressed PCM down tho...

Re: CenturyLink Question

Sure enough, we got a good rain and the DSL connection tanked again. I'm sure it's decrepit outside plant that they will do nothing to fix. Also, they seem to be short on backhaul capacity because our IP codec gets packet loss between 7 and 12 PM each night. So we have two problems that they will no...

CenturyLink Question

Anyone else here have the misfortune of having a site where the telco is CenturyLink? Got any backdoor numbers for Tier 3 support/repair? I have an AM/FM translator site using a Bridge-It for IP feed over DSL. It rained for a day and a half, the DSL downstream SNR dropped by 8 dB, the modem began to...
