[MRIC] Some advice, please

[Dan Blasberg]

Bob,

Short and sweet answers.

1.  You only need one Node/Internet gateway, it does not need to be  
hooked up to HF and it does not have to be set up for local hubbing.   
Start out simple with a gateway/Node and a couple of stations to be  
able to pass messages with-in your county.  If you need to interface  
with other jursidictions in MD and your node is down, see what the  
frequencies are of the neighboring jurisdictions are and try to  
connect to their node, or set up an HF station ($$$$$) and connect  
that way.

2.  Several Jurisdiction are using the same frequency for their node/ 
gateway at their EOC (145.750) without any interference to neighboring  
counties (even when all are using airmail/winlink at the same time).   
I would say use 145.750 at your EOC and then set the stations to that  
frequency to connect to the node.  As a default, the gateway software  
is set to accept five contacts at the same time and works quite well  
up to at least 12 (the max we in Prince George's County have been able  
to get on the air at the same time).

Questions, about doing VHF winlink, let me know.
