[digitalradio] ROS QRV now on 14101

Andy et al.

Looks like things have moved along and everyone is currently 
transmitting (simultaneously) on 14101 at present.  However, I can't see 
this being very successful venture given the limited space available and 
the required spectrum width for the transmissions. There are/were at 
least 4 separate qsos attempting to use the one channel. 

I am a little concerned that this will gradually smear upward and 
interfere with the the long-established and current use of Olivia in 
32/1000 mode on 14105, 14106 and 14107.  At least each Olivia 
transmissions takes up a 1 k slot and is in practice channelised which 
helps with simultaneous activity on adjacent 1 k spaced channels. 

Any further suggestions for activity hot spots for this interesting new 
mode?

Hi

Many years ago I had a G3PLX Mk II board which was interfaced to a RTTY 
system to send and receive AMTOR.  It was basically very close to the 
AMT-1 system without the modem.  I think I have the board still but in a 
modified form and I have no data on the board at this stage.  It did 
work extremely well for me when used with an ST6 type TU.   So too did 
the KC7WW software used with the same TU.
