Re: replacement LNB

Another thought is...has frost heaving affected the dish aiming?

Re: replacement LNB

That ought to work.

The 3120 has a better stability rating, +/- 5kHz vs. 10kHz for the 3220. Don't know the cost difference though.

Hopefully, you're not getting 5G interference already.

Re: Dynamax Module Auto Turn-On After Power Outage

Was that circuit in one of the manuals? I think I have a copy of the manual at home.

I could use that feature too...there are five Dynamax consoles in service at one of my clients' two studio locations.

Where do i get newer? Is this "MediaKind" version an official firmware for Ericsson/Tandberg?
Mediakind is the name of the company that now produces the RX8200.

Re: Nautel AMFET ND5 blowing output network caps

Not at all familiar with Nautel AM's, but is it normal for the coils in the output network to run hot enough to burn those coil forms?

Re: BE AM-1A power issue.

The first time I worked on an AM-1A, the battery had been ignored and it had exploded! That was fun.

Re: Does licensed or limited access wifi exist?

And, if your bandwidth requirements aren't great, and you already have buried copper between the school and the press box, I've used Startech ethernet extenders (basically a point-to-point DSL). Worked fine for our purpose, connecting two switches in an old multi-story office building using existing...

Re: Does licensed or limited access wifi exist?

If you can get fiber into the press box, you can mount a switch and go copper to the streaming gear. Leaving a little bandwidth for radio broadcasters would be nice, too. :mrgreen: Licensed microwave would be the next step. Be aware that the 5G lobby is trying to gobble up 6GHz for themselves. Unlic...

Re: Installation tool for AVA-7 Heliax?

Just wondering if there's anyone not terribly far from Syracuse (New York) who has the stripping tool for AVA-7 (1-5/8") Heliax? We need to replace connectors on a run for a microwave receiver, and it turns out that the newer Commscope connectors need a different stripping and flaring profile ...

Re: Quality translator

ferrites on the coax I missed this first time round, and Deep Thought's photo reminded me of it. What's with the ferrites on coax? I get ferrites on signal cables, they get rid of RF where there shouldn't be RF, but I'm having some difficulty understanding why ferrites on a coax? Ferrites on the co...

Re: 1080i60=>1080i59.94?

Been there, done that. FS1 won't do it, but the FS2 will...and it has two video processing chains, so you can do two security cams, or a cam and an Apple TV box using the HDMI in, etc.

Thank you very much Mark...you're a real swell feller. :D

I also have a pile of EFJ coils to decipher.
