SCA RADIO
 

Hello,

I know that in the past SCA radio carried of "book reading" for the
visually impaired and Muzak. But I just recently came across some
posts in the newsgroup archives saying that SCA stopped broadcasting
Muzak.
If this is so what else is available on SCA? And is Muzak available
over the airwaves some place else?

Thanks in advance.

SCA's carry a lot of digital data now, as well as some paging services and
non-muzak background music and news services. Muzak is now using satellite
to broadcast their service.

Here in Detroit, there are 4 non-data SCA services that I've
monitored.

1) 88.7 -- 92 kHz subcarrier -- 70's pop music continuous
2) 98.7 -- 67 kHz subcarrier -- elevator "muzak"
3) 101.9 -- 67 kHz subcarrier -- reading for the blind
4) 101.1 -- 67 kHz subcarrier -- studio to remote broadcast link (for
live broadcasts -- this link allows a DJ in the studio to have a
private communications channel with a remote DJ.

Other cities have similar services I'm sure.

Muzak is NOT encrypted. They are on satellite G3 (Galaxy 3) on Ku
band using an analogue subcarrier scheme called "FM Squared". These
are subcarriers, similar to the subcarriers that are commonly used on
analogue satellite stations except that they are in the range of 0 MHz
to 5.8 MHz instead of the commonly available 5.8 MHz to 8.2 MHz range.

I believe that all of these Muzak services are on Galaxy 3 Ku band
channels 3 and 16.

There used to be a couple of adaptors available for outboard satellite
stereo units that would allow you to tune this range. I have one from
a company called "Universal" that adapts my outboard Drake SA-24
satellite stereo decoder to tune FM2. I remember that it cost about
$100 when I bought it in the early '90's.

Hope this helps,

Fred E.

Awesome!

I actually have an SCA radio-I saw it at a thrift store. It's a cheap
Chinese radio labeled "Success" and has 0-10 SCA scale alongside 88-108
Mhz FM. I couldn't recieve anything on SCA mode, and I'm in a medium
sized city (about 1.5 million people total, including suburbs).

Did you check on each active FM station? Only about 6 of the Portland area
stations were using SCA's when I was working as a broadcast engineer there.

Thanks to everyone for the information. It is much appreciated.
I do have one more question though.
I am looking for someone reliable to convert either my SuperRadio3 or
my DX 390 with
a Sca Decoder Kit.
I wrote e-mailed for Dr Elving at the FM Radio site but got no reply.
I also gogooled to no avail.

Any info would be greatly appreciated.

ThankYou
