Re: Synchronizing FM over IP?

In our area, this has just been turned on: https://www.rbr.com/a-bustos-media-fm-boosts-with-maxxcasting-plan/ In practice, I think the network has helped the situation a lot. I haven't listened enough to decide to what extent it's "seamless", or whether (in my opinion) the net result might be wort...

Re: Weird satellite problem

Have you looked at the satellite downlink on a Spectrum analyzer to see what it looks like? It's not unusual for LNBs to start "spiking" across the band, and you could have an issue where one of those spikes are near your desired carrier. Could also be cross-pole. Your cross pole could be a touch of...

Re: Mrc mtx5000 ODU power pinout

Several decades ago [edit: about 40 years ago!] , the local NBC affiliate bought a package deal from Central Dynamics that included a large production switcher and a fairly large routing switcher (the video crosspoint frames took up a whole rack, as I recall). The production switcher was fine, but ...

Re: Ericsson 8200

BTW I was at your tower last week getting some nice weather updated pictures of it. I saw a van there but didn't want to bother who was inside. Hmmmm... I wonder who that would have been?

As far as I know, the best way to unlock the front panel is through the web interface, advanced page, "Device Info" tab. Jeff My co-worker make the mistake of doing an update with windows firewal...

Ericsson 8200

The 1290 Push and Hold Right arrow trick isn't the same on the 8200 apparently.

You may have one of your Pallet Amps that is Burnt and only making half the power and Your IPA is only working on one Pallet. Not sure if your ECO 10 has 2 or...
