I think (but am not completely certain) that they are 7:00-9:00 AM, 12:55-1:05 PM, and 4:00-6:00 PM.

Re: TFT 450 Mhz "STL" receiver

The models for the TFT "Marti" style equipment were 8888 and 8889, I can't remember which end was which. They had DIP switch programmable frequency selection for the 2 channels and the bandwidth on the TX and RX units could be selected to fit 25, 50, or 100 kHz channels. Had one at an LPFM but it ha...

Re: Theory Discussion: Circular Polarization Vs. Vertical Polarization

True, I even think some of them have the boosters also licensed as aux facilities or have occasionally had STA's that requested the booster be treated as an aux.

Re: Theory Discussion: Circular Polarization Vs. Vertical Polarization

Here's what an RF friend of mine thinks: "Circular polarization is probably not the best idea for FM. Broadcasters use circular polarization because they are limited in the amount of power they can broadcast with. In some states, they are limited to 100kW on an open channel- so they usually broadca...

Re: Simian & Windows Updates

Windows 10 on an automation computer would scare the snot out of me, unless I had it blocked from all internet access.

Re: Off-air monitors?

That's odd, I have mine running at 44.1. I think the RadioShark went through a number of different hardware iterations, maybe yours has a 32k sample rate instead. I had 2 different Shark units for testing since they were going for so cheap on eBay, one is an original white model and the second is a ...

Re: STL options

Fixing to add a translator feed over the same circuit but using Tieline Bridge-its, another pair of which we are currently using to feed another translator (no hot backup). I don't like them all that much but most of the time they're ok. Also have Cox on both ends for this other connection. The Bri...

Re: Any word on the length of the pending NPT?

So, it will then be cut off at 2:00 minutes by all those decoders that haven't been recently decoded. Or perhaps even by those decoders that have been upgraded--if they left the 2 minute limit in place for the NPT. Three minutes to control the audio of all radio, TV and cable outlets in the country...

Re: Remoting sat receivers off site

Some of the Comrex units have up to four closures...Met. Opera uses this system for stations that can't use the NPR satellite. More closures? A problem. In theory should work--touch tone encode/decode devices. Worked well for me when I had to lash up 8 contact closures for a satellite program betwe...

Re: Setting ideas for an Optimod 9100a

Microwave is not an option when one fails to deal with line of sight issues. Thought actually expressed by a corporate engineer: "(not an exact quote) go find those trees impinging on the Fresnel zone and have them cut down!" This same individual would probably recommend bringing in a wrecking ball...

Re: Setting ideas for an Optimod 9100a

I help take care of an outfit that has an 8k analog circuit feeding an AM and a 15k digital (nailed up ISDN) feeding the FM translator. Since the telco charges on distance, and the sites are just 2-3 miles from the station, it was cheaper to use PTP circuits. I suppose we are screwed if they decide ...

Re: Good ole analog

I have one of the Nicom analog units as a backup. Haven't used it for a while but it worked last time it was tried. The primary is a Starlink digital which works great since the path is short (2.5 miles). The transmitter site is in a metro area but was a black hole for internet. The only service ava...
