G'day all,

I'm hearing a data transmission of some sort just below the 40m APRS
transmission. APRS is 7.036.3 lsb on my FT107-M, the unknown signal is at 
7.036.0. The shift is apparently 200Hz.
I've tried every mode on "multipsk" and cant resolve it.
I can't remember if this list takes attachments, but I have a picture of
it from "Multipsk".
Anyone got a clue?

Hi Norm. I was about to ask you what strange digital mode you were using
as 
your beacon on 40, hi-hi.
The mode appears to be a standard T 30 Phase B fax command protocol. I
have 
my decoders packed in a box at the moment whilst I reorganise the shack to

accommodate a few new items, but I'll load one of my Yamaha YM7109 cards 
into the comms machine tomorrow morning & see if I can't get a better
idea.
Pity I can't transmit on 40 yet, as I could emulate the handshake &
perhaps 
the fax would be sent in it's entirety.
Time: 9:40 PM ESDT.....current mode is fax (see above).
73,
