Someone on the list sent me some information Friday regarding ALE decoding and 
the different types of protocols used....but of course I've lost the email now. 

Could that person please re-send..... 


Just for the list's reference, he passed this link which was very interesting: 

http://www.chbrain.dircon.co.uk/ 


This is an ALE sound card decoder for the 2FSK type ALE that sounds like a 
"turkey gobble"  Interesting stuff....  Now we need some development activities 
around the Harris 4FSK ALE that FEMA and the US Customs Svc uses.  Anyone...?

What is a "slow" ALE versus a "fast" ALE? 

Does any one have a way of demoding either one?

The "slow" ALE is the type that sounds something like fast dripping water....it 
is a distinctive sound.  The "fast" type is the ALE that the US Custom COTHEN 
Network uses. 

I don't know what the official names of the ALE protocols are...I just call'em 
fast/slow.

SHARES, the SHAred RESources message system/ frequency pool of something
like 23 Federal agencies, has reserved six of its ten coordination net
frequencies for ALE.


These freqs have run everywhere, but here they are again:


1   5236.0  Shares Co-ordination Net Voice Primary (night)
2  14396.5  Shares Co-ordination Net Voice Primary (day)
3   4490.0  ALE
4   5711.0  ALE
5   9106.0  ALE
6  11217.0  ALE
7  15094.0  ALE
8  17487.0  ALE
9   6800.0  BBS (packet or PACTOR)
10 13242.0  BBS (packet or PACTOR)

These had some activity in hurricane Bret.

In other news, it sure sounds like McClellan GHFS is getting its new
radios.  They're testing on 8992, and on 11175 they appear to have a choice
of transmitters, the new one being way, way louder in Los Angeles, not to
mention just more solid and authoritative sounding.

Yes,
Someone was kind enough to email me a copy of the 
sound ALE makes. I had read about about it a few months ago, but forgot 
about it.

Hi Keith and the list,

I hear this question quite often, which is why I've posted it to the list
instead of in private mail.

ALE stands for Automatic Link Establishment, this is a transmission mode
that has a very distinctive sound when liistened to in USB and there's
little chance of mistaking it for anything else. It is used extensively by
the US military, but its use is not confined to the military, as Jack has
noted it apparently in use by the FBI, and I believe it has been noted by
others being used in FEMA nets.
