Re: Baofeng thoughts

I've got a dual-bander. I'm not particularly active so don't have a huge amount of experience with it. It did behave usably for simplex chatting around the grounds at the Dayton Hamvention. (back when there was a Dayton Hamvention. 2020:( ) It's clearly not built to the standards of a Kenwood/Icom/Y...

Re: Does licensed or limited access wifi exist?

We've had very good luck with unlicensed 5.8GHz gear for two video circuits. Yeah, someone could plop something down on top of us (hope I'm not about to jinx our circuit) but we've been getting reliable bidirectional 200Mbps or more for several years on two circuits of roughly five miles each. One c...

Re: TV Audio Processing (circa 2000-2003)

(concur, on the kudos for Jeff's detailed explanation of his plant!)

They were 8182s.

The Audimax/Volumax are so far back I have no idea what model numbers -- except to say there were no tubes:)

Re: TV Audio Processing (circa 2000-2003)

In our case yes, analog Orban Optimod. Our stations (the one I work for now, and the one I left 30 years ago) were stereo, so the stereo generator was built-in and preemphasis was part of that. In the analog era, many TV stations did NOT broadcast in stereo. Preemphasis was built in to the transmitt...

Re: 1080i60=>1080i59.94?

That's good to know about, thanks!

In our particular case, I have a FS-2 I can steal. $395 is a good price, but zero is better:)

Re: 1080i60=>1080i59.94?

I'll be darned, it indeed does! We have two -- and I think I can get away with stealing one. (and replacing it with a FS-1; it's in an application where it's only going to see 59.94 & we can live without dual paths) I later learned a Blackmagic Teranex will do it too. But we'd have to pay for th...

1080i60=>1080i59.94?

Anyone know of a device that'll make this conversion? We want to use a security camera as a towercam. The ones I'm finding all output 1080i60. Of course, in the security industry it doesn't matter but in TV that 0.06fps is a significant problem..... The Aja FS-1s and Blackmagic UDC cards I have avai...

Re: New engineer - questions

What I did... was both ham radio and broadcasting. As you noticed, it's perfectly legal (even encouraged) to build your own ham gear. No, you can't broadcast shows but you can certainly tweak your equipment for the best possible performance and chat with other hams to pick up tips. Most hams don't u...

Re: Studio360 Digicarts & Ubuntu NFS server?

I finally figured out why NFS wasn't logging anything... turning the logging on at once sheds light and raises more frustrating questions... When I select the path on the Digicart, I get in /var/log/syslog on the NFS server: Received EXPORT request from 192.168.1.17 Then, when I hit ENTER to confirm...

Studio360 Digicarts & Ubuntu NFS server?

So, I've got a couple of old Studio 360 Digicart/E units. I was feeding them files from a Ubuntu NFS server. The server hardware finally died. I built a new Ubuntu machine on new hardware, and I have backups of all the audio. But I can't get the Digicarts to connect to the new NFS server. They know ...

Re: Renewal season

My apologies for resurrecting an old discussion but... How early is too early to file for renewal? A local LPFM expires in August. They know their renewal is due by April 1st, and would really prefer not to challenge that deadline -- but they don't want to be ridiculous about it. I see one LPFM here...

What do you all think the chances are the FCC will, in the next 3-5 years, allow AM stations to silence the AM signal & operate only on the translator(s)?

Re: The Looming Engineering Age Crisis

Also, I’m primarily speaking to radio’s issues, not TV’s. TV's issues are pretty much similar. I think we're following radio's lead, just maybe 10-15 years behind. I think we're going to continue to see staff engineers in TV, but I can envision a station having only one, one with only IT experience...
