Re: Audio dropouts on Yankees game broadcasts

Logging? I couldn't tell you and I'd bet not a single byte has been recorded. As the recording won't affect the air product, no time or money will be spent on it. That's the way this cluster operates. Fortunately there are other affiliates carrying the games and I can just as easily listen to one of...

Re: Audio dropouts on Yankees game broadcasts

I know y'all are waiting for further info on this. So am I. I was supposed to go to the station Tuesday afternoon (4/16) with my spectrum analyzer and some lunch but the engineer was out of the office and didn't answer any of his phones, so I just bought lunch for myself and went home. I'm now waiti...

Re: Audio dropouts on Yankees game broadcasts

The other affiliate might be using an ISDN line or something similar. I would expect more delay on an internet connection. They may not have any other satellite programs and figured for one program it's cheaper to use wires than install a dish. Yes, they are west of me and can probably see WFAN's an...

Re: Audio dropouts on Yankees game broadcasts

I recall seeing a figure of 13dB on one display. I think the best it can be is 15dB. Apparently the receiver vendor is resisting replacing the receiver, claiming it has to be something else (the old finger-pointing ploy). Naturally the station doesn't have the $5,000 to fork over for a new one. I li...

Re: Audio dropouts on Yankees game broadcasts

Thanks for all the comments. As mentioned in an earlier post, the receiver is an XDS- PRO4 DVB receiver. It's picking up the C-Band satellite: SES Americom 11 (SES-11), at least for Yankees games. I don't know if the sat dish can pick up signals from multiple satellites. The dropouts are very easy t...

Re: Audio dropouts on Yankees game broadcasts

I don't know enough about the sat receivers. Can they handle multiple programs at the same time? What is broadcast on this "test" channel? Is it tone or an actual audio source they don't care about?

Re: Audio dropouts on Yankees game broadcasts

Actually I did listen to another station last year, and never heard a single dropout. They could be getting the feed via a different source. They probably could easily record it as they record and delay other shows to be aired at a later time. It would be much easier to do during a day game, but tho...

Re: Audio dropouts on Yankees game broadcasts

Additional info. The CE checked the logs in the sat rcvr and it reported a couple of signal fades but not at every dropout. He's going to put a spectrum analyzer directly at the antenna input of the rcvr and see what the signal is doing. Last night's game was a late one and I noticed one dropout at ...

Re: Audio dropouts on Yankees game broadcasts

I believe they use WestWoodOne. I've heard "WW1 radio network" on games aired on WCBS/880, but WFAN/660 airs the Yankees games and at least a dozen other stations rebroadcast that signal. I can hear it on WFAN plus two of those others. I know Entercom bought WCBS and I assume WFAN as well as WINS, a...

Re: Audio dropouts on Yankees game broadcasts

I don't know the sat freq or the filter range but I'll try to find out. If it is aircraft radar, that could explain the intermittency of the dropouts, and it might just be coincidental that the first dropout doesn't happen until the program has been received for an hour or more.

Audio dropouts on Yankees game broadcasts

For day games that begin with a pre-game show at 12:25pm and a first pitch at 1:05pm, the first dropout is usually around 1:30pm, or about an hour after the program begins. The dropouts last for a syllable to a second and often there are two that happen almost immediately, like a stutter. They don't...

Re: Very low power recommendation

Bird (part of TxRx) and Narda make coaxial attenuators in various power ratings. A 6-10dB attenuator rated for a few hundred watts will have no problem reducing a 50-300w transmitter down to 10w TPO. Probably will take up less room than 100ft of coax. I use a 30dB 50w attenuator with two-way radios ...

Re: Very low power recommendation

You can also tell google NOT to return results from specific sites (such as ebay) by adding a hyphen and the major part of the site name (no space between them), as in: 10w fm transmitter -ebay It's unfortunate that google returns ebay auctions for stuff that's long-gone, sold, or even non-existant ...

Re: Timed Capture of Measurement on Anritsu MS2721A/B

How about a small interval timer and a small doorbell-size solenoid sitting over the button you need to record/save the trace? It seems that all you need is a finger to push a button every so often, so make a finger.
