Constructing, Installing, and Configuring TheNET X1J/4 NODES

DUAL AND MULTI-FREQUENCY NODE (STACK) OPERATION:

To realize the full potential of TheNET X1's high-level

networking capabilities, it is an excellent idea to

minimize

interference between local (uplink/downlink) and long-

haul (crosslink) traffic. One good way to accomplish this

is to reserve one radio frequency exclusively for inter-

node traffic, to provide end-user access to the nodes on

one or more separate frequencies, and to discourage

(ideally, to prevent “ACL”) end-users from using the

inter-node "backbone" frequency. This approach requires

network nodes that can access two or more frequencies.

A REAL “SIX-PACKet.” NODE-STACKS

PERFORM CROSSLINKING BETWEEN TWO OR

MORE FREQUENCIES OR BAUDRATES. SIX

MFJ-1270C’s EQUIPPED WITH X-1J4 EPROM .

The node stack shown here is located atop 3000 foot,

“No Business mountain” in central Virginia.

The MFJ-1270”C” can be equipped with the add-on MFJ-9600 (9600 baud) Modem. The MFJ-1270CQ Turbo is a

complete 300, 1200 or 9600 baud TNC. All MFJ-1270 “B” / “C” and PacComm TNC2 clones are X-1J4 TheNET

node compatible.
