ROLLS radio

P

perenoel6218

Has anyone had any experience using the ROLLS radio am/fm for the
primary EAS receiver. We have noticed it has very little audio strength.
 
I have two of the little $150 tuners--have to run them through a twin-match to get adequate level. Also one seems to generate noise in the UHF region--trips the squelch on a Marti receiver in the same rack.

A cheap, yet good AM/FM tuner is the Sony XDR-F1HD tuner. Getting difficult to find, but a Google search turned up a number from $79 to $92 dollars. It's fairly sensitive & has adequate output.

You have to have it on battery back-up--but that's true of a lot of tuners. And it's not good for air monitoring--has a bit of delay even in analog.
 
AsI recall, EAS receivers have to have a visual indication of proper tuning. I am not sure that a digital frequency display like on the Sony radio would be adequate. You also have to have a visual indication of audio presence, which is most frequently done on the EAS unit.
 
Rolls tuners are nothing short of horrible. They aren't selective. They aren't really sensitive at picking up distant stations very good. And, the filter caps will die in less than ten years and you'll get to replace them in order to get rid of the damn buzz from AC ripple. There's several decent options out there. Rolls isn't one of them when it comes to tuners. Tascam, Denon, Sony, Dayton, whatver. Just RUN from a Rolls if at all possible!
 
The displays tend to burn out and the audio quality from even strong broadcasts is fair at best. There are better options.

I don't think that is correct. Perhaps it was a requirement back in the day, but not now.

There is a requirement that the EAS decoder be able to display that it has audio at the audio input. (11.33 (5))

But that's a decoder requirement, not a tuner requirement.

To think that an analog tuning receiver with a signal tuning meter would be acceptable, but a digitally tuned receiver that doesn't need such an indicator would not be acceptable, is a really strange idea.

None of the old SAGE Endecs have an indicator that show audio's present.
The SAGE rack reciever has LED audio and signal indications.
A NOAA reciever I put together has LED signal and audio indicators.
 
You would have to install all of the mods to the Sony XDR-F1HD to make it work dependably. It runs hot, and it loses it's mind when power is lost, even for a moment. And then it is kind of overkill for EAS.
If your studio is far enough away from strong local FM transmitters, the Dayton AF225 FM tuner with dip-switch tuning will work quite well. They stay on frequency, and are simple enough to "get 'er done" without bells and whistles. For AM, the AF315, and for the NWS, the Af612 work very dependably.
 
Agree on the power backer, but never had any other problem with the Sony's. Besides, what else can you get for under $100?

For $129 from Amazon dot com, the Sangean WR-2 might be a decent choice. It is a nice radio with all the right inputs and outputs. (OK, I lied: The audio output is unbalanced.) I think you'd need to run it on a UPS, but that seems to be a common thread for just about anything these days.
