Strange skills learned
A broadcast engineer is, of course, expected to learn on the job. Sometimes, one is expected to learn skills WAY outside the job description. Like deer herding. As I'm sure is the case at many of your stations, our employee parking lot is fenced & gated. Yesterday morning, a fawn decided to follow o...

Re: Restoring a small transmitter
Sounds like it may be an AL-811, with three 811A tubes in parallel. A copy of the manual (with schematic) is available on http://www.ameritron.com/Downloads/index.php?productid=AL-811&filename=AL-811.pdf&company=ameritron . I would be cautious about operating this amplifier at 400 watts output in br...

Re: Tomato Soup Incident
1. I wonder what the lab director said when he saw his vat of expensive demineralized water contaminated? :D 2. Touring a UHF TV transmitter... saw , in the middle of a few feet of insulating hose, a metal fixture with a wire attached. Seemed strange, as there was no other electrical connection. (at...

Full Compass: online ordering issues?
Anyone else having trouble with Full Compass' website? Twice this week I've tried to order something online & found the external credit card processing site never responds. I seem to have developed a bit of a sore throat at the Hamvention & was trying to avoid using my voice but it looks like that's...

Re: Compression Question
Let me second that. We want it normalized, but would rather handle any further processing ourselves.

Re: Am I a possible engineer candidate?
Curt, so far you've heard from radio people. The situation in television is better, although I'm not going to say it's a bed of roses. - The money is better in TV. Not great, but better. I do suspect you're doing better in your current job. I will say, most folks I've run into trying to make the mov...

Re: Leitch Panacea reclocked outputs
Strangely enough, the Panacea manual ( http://www.imaginecommunications.com/sites/default/files/documentation/panacea_frames_and_modules_user_guide_20110501.pdf , see page 31) doesn't list 720p50 as a valid format: Standards of operation 525 60/1.001 625 50 720p 60/1.001 720p 60 1080i 50...

Re: X-Y protocol??
I had a frustrating issue with something similar.... I can't find it on the BMD website now, but they at one time sold a DVI extender which pushed SDI over 1694A. Worked fine for the intended purpose, but one guy thought he could use it as a DVI-to-SDI converter. Problem is, it told the computer it ...

Re: X-Y protocol??
So I wasn't imagining things about RS-422. It's been a few years (like fifteen) since I've had to work on an X/Y system.
When we went digital (and before we went HD) I had to get a small Jupiter working as the back-end for a Saturn MCR. I still have nightmares.

Re: X-Y protocol??
That's indeed a rather broad question:) It's a way of connecting control panels to a router, introduced by Leitch. (later Harris later Imagine which still sells X/Y products) Physical connections are a 75-ohm coax bus terminated at both ends. I have a vague recollection there's a way to make it work...

Re: Replacement for HD-Star
They let me have ours back:) From the Main Menu; - Sig Info - ANC Status Any ancillary signal that's present shows up in white. (it's grayed out if it's not present) It'll also show red if the packet is present but has errors. The Setup button lets you define the three User-n options at the bottom o...

Re: Replacement for HD-Star
Of course, one of my guys is using ours somewhere else right now... There is a screen that shows a present/not present for a variety of well-known DID/SDID combinations. At the bottom of that screen there are (IIRC) three "User" combinations you can set to anything you want. I was having problems wi...

Re: Replacement for HD-Star
We also have a Phabrix. Upsides: - Far more available tests. (for example, it will check for specific DID/SDID combinations in the ancillary data. Like NBC Namedropper cues.) - Reads AES audio. - Appears to be better built physically. - Networkable. (although we haven't looked into that function yet...

FM translators of AM stations
I was curious -- ran a query against the facility and int_translator tables of the CDBS database this evening. 73.9% of all authorized AM stations are the listed primary of at least one FM translator license, construction permit, or application. That figure does not include AM stations which are rel...
