Ron Rackley SK

In case someone here hasn't heard... Ron Rackley passed away last Friday. The family is requesting privacy and no details are available at this time.

Ron was a good friend and brilliant mind. I will miss his wit and wisdom.

Regards,

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? Bob M. It depends on the syndicator but it typically is an unencripted, repeating voice message with...

Re: Audio dropouts on Yankees game broadcasts

However, since the test channel is coming out of the LNB on a slightly different frequency than the program audio, I could be very well be wrong but I had understood that all of the audio streams were mass encoded (QAM?) data upon a certain syndicators carrier. Then the RX receives the RF signal, d...

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 th...

Re: Gotta love Westwood One

Yeppers. And it's NOT a vanity call...lol. Yeah, we lost the Super Bowl that year, along with dozens of other stations. Westwood claimed an instrument from a nearby marching band generated a sub-audible note of the right frequency that tripped their decoder. I guess they never heard of a high-pass ...

Re: How to bridge 600 ohm balanced line to monitor or record?

It could even be the transmitter but that currently seems unlikely. If we can bridge the balanced audio and record on a pc... once we hear the problem we can note the time and on air content.... then listen to the recording to see if it occurred at that node... Intermittent problems can be maddenin...

Re: How to bridge 600 ohm balanced line to monitor or record?

An RDL STA-1 (or STA2) is my goto for this kind of thing. Either will drive a set of headphones at low levels directly OR cleanly interface to a computer or audio amp. A DA is another option as you mentioned but more expensive. A telephone buttset is also a common quick test set. A camera recording ...

Anyone remember WW-1 firing the EOM during the Super Bowl pre-game a few years ago? What a cluster **** that was!
I bet that went over like a "wardrobe malfunction"...

Is N8RAT your ham call?

Re: RDS options

There is a document that covers this from the RDS Forum. It is old, but still relevant: http://www.rds.org.uk/2010/pdf/R09_048_6_no%20pw_57.pdf . The important bits are highlighted on page 4. Page 40 of the NRSC guidelines also has some information on page 40: https://www.nrscstandards.org/standard...

Re: RDS options

I didn't think there was a way to make the PS "scroll" as the RT messages do. Like Kevin says, the PS text is actually static, it just changes every few seconds. I haven't seen too many car radios (if any) that will display actual scrolling RT messages, although most of them seem to work OK with "d...

Re: RDS options

The PS was always designed to be static in RDS, so scrolling it will give unpredictable results. Here in the UK, PS scrolling is not permitted. RadioText is the correct way to transmit dynamic text. Certainly in Europe, RT is increasingly displayed on car radios. I have turned off the PS scrolling ...

Re: RDS options

No idea how effective with the listeners but their customer that is paying for the RDS ads calls any time the old Audimat RDS encoders lockup or fail. Typical radio logic: Who cares if it works or drives away listeners as long as we can make some short-term cash! :roll: That is absolutely true... H...

Re: RDS options

Sell a few RDS commercials and drop them into a rotation of your station lines or song titles. I can't believe this is a thing. If I saw that on my dashboard I would immediately change the station and delete the preset. Has anyone done any sort of study on how effective this nonsense is? Seems to b...

Re: RDS options

I did actually see this application. The problem is this website is terrible. and now after review the cost of the darn product is $1000.00 The good thing about more advanced RDS software and encoders is that you can monetize your RDS. Sell a few RDS commercials and drop them into a rotation of you...

Re: Getting RDS to transmitter

Affordable and reasonably reliable bi directional serial port you can also use it as a backup audio link. Jim Just wondering are you using the STL software? We have been fighti...
