PACKET OPERATION
One of the most exciting benefits of owning an FM
transceiver nowadays is the ability to use it for VHF or
UHF Packet radio. TM-251/451 transceivers are ideal,
due to their small size, for operating Packet portable
from a local mountaintop, for example, even if the
transceiver is not permanently mounted as a mobile in
your vehicle.
By using a small laptop computer to control any of the
widely available Terminal Node Controllers (TNC), and
interfacing the TNC to your transceiver via the DATA
connector, you may be surprised at how compact and
lightweight a digital station can be. Operating Packet
while on the road from a campsite or hotel can be a
great way to meet others with common interests when in
a new area or city. Newcomers to digital
communications will be surprised to discover what they
have been missing.
Similarly, by connecting a home computer or dumb
terminal to your TNC/transceiver assembly, you can
become active on Packet with little further monetary
investment. Connecting to one of the many stations with
gateways to HF or satellite links can give you national
and worldwide messaging capability from your station
with nothing more than your VHF/UHF transceiver for the
communications link.
