gateway (145.75 MHz, just across the street at Hughes). Set the IC-7100's frequency.
the Winlink Express session window, the connection type should be "Direct" (in other
words, we are not using digipeaters to reach the gateway since these gateways are within
simplex range of the hospital). Type the callsign into the connection box, and click Start.
After a few seconds, the radio should begin transmitting and establish a connection with
the Gateway. You are off to the races!
You can also try these other stations:
Call Sign Frequency
WA3SWJ-10 145.750
WA3YOO-9 145.75
WA3YOO-10 145.75
W3LRC-10 145.750
W3PGC-10 145.750
W3AAC-10 145.010
N2LEE-10 145.730
Unfortunately, the hospital is surrounded by substantial ridges in virtually all directions.
This makes simplex VHF/UHF communications a bit of a challenge. You may or may not
be successful in reaching the stations listed above, except for WA3YOO-10, which is
literally across the street from the hospital.
In a pinch, you should be able to establish a packet peer-to-peer (PTP) connection with
another local station to relay any critical message traffic. It is also possible to make a
Winlink connection over any of the RMS Gateway stations listed above, or even over a
conventional FM repeater. (You may need to increase the TxDelay setting to several
hundred milliseconds when operating over a voice repeater.) In an emergency, when the
MCACS station at the Montgomery County EOC is activated, you can contact WA3YOO
to request assistance in relaying Winlink messages.

Note that the Winlink Express program does not tune the radio when you switch to a different gateway
station. This must be done manually.

If you cannot connect to N2LEE-10 directly, try digipeating through the RESTON digipeater.
