Sydney DownUnder Side - Technical information courtesy of Peter - VK2ZPT

The downunder side of the phoenixdownunder.net link is hosted from Peter VK2ZPT's QTH in Baulkham Hills, NSW via a 70cm feed from the HADARC repeater site in the north of Sydney and linked back into the VK2RNS and VK2RAT repeaters via 2 metres. Equipment is a P4 with 1GB memory running Fedora Core 4 and EchoIRLP software withTX and RX equipment from Icom. The nodes are 6338 for IRLP and 271006 for Echolink.

My IRLP (Internet Radio Linking Project) station node number is 3820 and it is located in North West Phoenix, Arizona. My IRLP repeater station frequency is 447.575 MHz, Minus, with a PL 151.4 Hz. I am transmitting the 151.4 Hz PL tone so that you may engage your radio's CTCSS system to eliminate the EMI noise around metro Phoenix from breaking squelch on your radio.

I also have three frequency-agile remote bases transceivers, a 2 meter remote base, a 1.25 meter remote base, a 0.7 meter remote base, and a fourth remote base linking into a virtual HF radio with CQ100. My CQ100 linking frequency is 29.290 MHz. Please just listen on this link frequency unless you have need to connect to my repeater or to control any of my other remote base transceivers. If you have need for these remote bases, drop me an email. My 2 meter remote base is normally "parked" on 147.460 MHz, simplex, with a PL of 151.4 Hz. You can control my IRLP node and Echolink Node through this 2 meter remote base link also. If you have 70 cm capability, it is best to operate on 447.575 as described above.

With this capability, I can get into my repeater and control any and all of my system, not only from any IRLP or Echolink node, but also from any Wi-Fi hot spot in the world. No more dry spots where I can't find an open IRLP node radio or an open Echolink node radio.

The output power on my 70 cm repeater is 30 watts, and the output power on my 2 meter remote base is 7 watts. The station antenna is a high gain (8.3 dbd on 2 meters, and 11.7 dbd on 70 centimeters), dual band, Diamond X510MA omni-directional antenna, and it is 65 feet high at the top. My station is open to all licensed Hams.

In addition to IRLP, my station also has Echolink capability. Echolink radio (non keyboard) stations may connect to my IRLP station, and local users of my IRLP radio station may connect to all Echolink stations (radio and keyboard). However the distant Echolink node must allow conference calls by checking the conferencing box on their Windows machine. Please see my web site below for more details and related links: http://irlp.wb7tjd.org/

To link-up to a IRLP node, key up, give your call sign, send the desired 4 digit node number. Example 1234. After the link telemetry confirms that the link is on, wait to be sure there is no traffic, then have your QSO. To down-link, key up, identify, and send 73 to down-link, wait until you hear the link-off telemetry, and then sign clear. During your QSO, be sure to pause 3 seconds at each transmission turnover in order to provide enough time for others to break in. Reset (for 3 seconds) at least every 3 minutes, or you will time out the Node. Key up for 1 second before talking to let the link and the distant repeater come up.

To link up to an Echolink node, follow the above procedure, but prefix the Echolink node number with the C key. Example (C123456). My Echolink node number is 173098. You can get all other echolink node numbers from the links below.
