[MRIC] Fwd: 2009-04-25 MRIC Meeting

Tue May 19 13:11:10 EDT 2009

Brett,

Let's be clear on the terms here, as winlink equipment can be anything  
from an VHF or HF Airmail station to and RMS packet Gateway to a  
Paclink station, etc.

Winlink is the overall network that includes four upper level CMS  
nodes that control the flow of messages through the network and to/ 
from the internet.  From there, are the RMS packet gateways, as of  
today, May 19, there are currently 412 RMS gateways online, this  
number is in flux based on active gateways.  You then have the user  
level, airmail (e-mail) stations of which there are thousands.

The three items I have gotten questions on have been:

VHF/UHF Airmail - Alinco DR-135, KPC3+ TNC, Laptop Computer running XP  
and Airmail
HF Airmail - Icom IC706MkIIg, SCS USB Pactor II TNC, Desktop running  
XP and Airmail
RMS Packet Node - I am currently responsible for two:
RMS 1:  Yaesu FT-90, KAM XL TNC, Desktop running XP and RMS software  
suite. (soon to have a UHF frequency added)
RMS 2: Alinco DR-135, KPC9612+ TNC, Desktop running XP and RMS  
software suite. (soon to have a UHF frequency added)

You seem to be fixated on the HF portion of the system and the  
settings required for it's use.  That is all well and good, but with  
all of the available frequencies for VHF and UHF there is more  
bandwidth and more data rates available in the event of an emergency  
compared to HF.  There is also a quicker clear time of messages using  
VHF and UHF as opposed to HF.  Not to mention that RMS can handle  
traffic from multiple stations in the field at the same time with  
minimal lag time.

So why don't you list your equipment st-up for everyone to see.

As a matter of fact, would anyone and everyone using any form of  
winlink/airmail please post their equipment set-ups?
