What is the North-South UHF link system?
The North - South system is a Amateur Radio Linked UHF Repeater system comprised of a number of repeaters connected together to provide a means of communicating via portable, mobile, or fixed stations over a wide area of Pennsylvania and Maryland.  This system was installed in 1993 and continues to provide excellent UHF communications over several mountainous counties in southwestern Pennsylvania, and northern Maryland.

Technical Operation:
This system is based around the 443.950+ N3VFG hub repeater located in Somerset PA. The HUB is used as the central link of the System. When connected, a linked repeaters audio is routed through the central hub repeater and is available for distribution to the rest of the system. Any linked repeater may be dropped from the system to provide local communications when necessary.  Outboard repeaters are linked via a simplex radio to the main HUB directly on frequency.  No "link" frequencies are actually used, rather the outboard repeaters are "remoted" or "remote based" to the HUB for simplicity.
 

Operating Guidelines:

Whenever you bring up the North - South system, please keep in mind that you're talking over a very wide area. If your conversation is local, it's probably better on a local system. If it's just filling air time, think of all the other stations listening. Quiet helps us to monitor, especially late at night. Please remember that this system was designed to be used in emergency situations, and it must be available when needed. We appreciate you using the system cautiously, The Somerset and Cambria County Emergency Management Agencies.

Things to do:

Pause a moment between keying and talking. Leave a second or two between transmissions.

Use the network for regional SKYWARN, or ARES / RACES operations.

Participate in technical discussions relating to amateur radio.

Let someone from N-S know about your planned operations, in advance, whenever possible.
(It helps us to make sure the system is ready.)

Send us performance reports by e-mail. (see links below)
