and Harrison Road on Tucson's eastside.

Is there a PL tone required to access the N7JND Echolink RF gateway?

A PL tone of 100.0 HZ is required to access the N7JND Echolink RF gateway.

The transmitter also transmits a 100.0 HZ tone so that you can activate your tone

squelch feature to keep interference out.  Most hams on 145.775 already 

transmit a 100.0 HZ tone so you will hear locals also.

What are the operating hours of the N7JND Echolink node?

The N7JND Echolink node operates 24 hours a day, 7 days a week.

Are there any restrictions on how long I can use the N7JND Echolink node?

There are no time limits on how long you can use the N7JND Echolink node.

 You are invited to use the node as long as you like. We do ask that you

 share the frequency by allowing others to join in or if needed, make a call.

There is however a 3 minute timer per transmission to help protect the transmitter.

If you exceed the 3 minute timer, the node will auto disconnect and become idle.

How many Echolink stations can connect to the N7JND Echolink node at one time?

The N7JND Echolink node will accept a total of EIGHT connects at one time.

What's the difference between a Wide Area Node and a Back Yard Node?

The Southern Arizona Echolink Node List found on this website will only contain nodes

that are intended to be used by the Ham Radio Community.  To be listed, the node must 

cover the city it's intended to be used in. These are Wide Area Nodes.

A Back Yard Node is an Echolink node put up by a Ham Radio Operator that is

designed to allow the node owner access to their Echolink station via RF, but the range

is usually 5 miles or less.  These nodes will not be listed on the Echolink node list.

We only want to provide Hams with a frequency list of Echolink Nodes that can be

accessed through out the whole city or town that the node is located in.

I have a question.  What's the best way to contact Chris ( N7JND ) ?

Why did Chris start an Echolink node?

Chris has always offered something to the Ham Radio community.  Back in the days 

of BBS's, Chris operated a BBS called The Outer Limits.  Most of it was dedicated to

the Ham Radio Operator. Today, Chris enjoys what Echolink has to offer. 

Does Chris accept donations towards the operating costs of the N7JND Echolink node?

NO!!!!!  Chris will never accept money to help with the operating costs of the N7JND

Echolink node.  Simply Put...If he couldn't afford it, it wouldn't be here. It's his hobby and

it's his contribution to the Ham Radio community. 

Are there any special rules that need to be known?

The rules are simple.  FCC Rules and Regulations ( Part 97 ) will always apply.

  Please don't "FAST KEY".  Always allow the system to drop before responding.

This allows others a chance to break in. That's really all we ask.
