[GreenKeys] TTYs in news service

[Anthony Vallot]

Alf:

Regarding internet access; here in the states, if your cell phone has
coverage, then your laptop or PC can have the internet also.  A USB device
plugs into the computer and gets the internet from the cell phone towers.

John, Duncan and all,
I would like to get something like this to work in the Signals Museum to 
bring some life to an otherwise silent machine.

Unfortunately, I don't have internet access in the museum so can't use ITTY 
etc but I was wondering if the likes of Reuters and other news services were

available on HF FSK?
Does anyone know what frequencies, code, shift and speeds do they use - i.e.

is it 110 baud ASCII perchance?

Regards,

Alf Fisher
Curator,
