LSAC EchoLink

KCMKS-R EchoLink Node #239444
Knife River, Minnesota

Rather than re-invent the wheel, please visit the EchoLink web site for more information about EchoLink!

The KCMKS-R Echolink Node runs 7x24 and is primarily on the LSAC 1 system. More information about both LSAC systems can be found at LSAC Repeater System web site. Thank you to Randy NBZZ and Pat KBQYC for their generosity and patience in making the LSAC systems available for EchoLink.

Nets on the LSAC 1 Repeater System:

Occasionally the node may be disabled or in receive only status. Generally speaking this occurs when there is a major event taking place and no interruptions to that event via EchoLink can be tolerated. Such events may be:

If you should notice problems with the KCMKS-R EchoLink node, please report them promptly to Jeff KCMKS via email or on the air.


Access to KCMKS-R via the Internet

The KCMKS-R EchoLink node is a closed system and therefore all EchoLink nodes that connect need to be in the authorization list. Please contact Jeff KCMKS to have your call sign added to the list. For security reasons, all connections are logged.

If you try to access the KCMKS-R node from another repeater system, the EchoLink node on that other system would also need to be added to the authorization list.

Due to the available bandwidth at the node location, a maximum of 9 connections are allowed at any given time.


Access other EchoLink nodes via an LSAC Repeater

To prevent accidental interference with repeater operations, the repeater owners have allocated the use of DTMF key "C" to be used at the begininng of every EchoLink command. Please note that due to the total number of link radios in the path to the EchoLink node, DTMF access may be limited. For example, using the Moose Mtn. receive site, the path to EchoLink goes through 8 radios including your own...

To control EchoLink from the LSAC Repeater System, use the following commands:
Connect Cxxxxxx Connect to another node where "xxxxxx" is the node number
Disconnect C# Disconnect the most recent connection
Disconnect All C## Disconnect all connections (panic disconnect)
Node status C8 Check to see if any nodes are connected
Information C* On air help via a menu system

Every hour there is an on air announcement for EchoLink. Within that announcement is the instruction on how to access the on air help menu system. The help menu is an small piece of software I wrote that communicates to EchoLink through an API (Application Programming Interface).


About the KCMKS-R EchoLink node

The KCMKS EchoLink node transmits and receives on the 7cm LSAC Hub Linking frequencies. EchoLink runs on the same machine as a number of other internet applications. The computer is dedicated to serving only internet applications. The computer-to-radio interface is a homebrew that is totally electrically isolated to reduce noise and hum problems. The Kenwood TM-71A radio is powered by an Astron RS-2A and running at 35 watts. To eliminate background hiss, due to the 42 mile trip across Lake Superior, I use a roof mounted heavy duty Arrow Antennas 440-5S (5 element 44) Yagi that is pointed at Bayfield. Since our location here in Knife River is at the top of a ridge about 4' above Lake Superior, we get winds in excess of 6 mph four to five times a year whenever a "noreaster" blows in. Hence my reason for using the heavy duty Arrow Antennas. Our location is also line-of-sight to both LSAC 1 and LSAC 2 Hub locations.
