Output frequency: 430.100 MHz

The 70cm repeater PI2EHV has been providing service to Eindhoven and around for many years. The repeater is built from a heavily modified Bosch KF452 with filters built by PA3CEG.

The repeater requires CTCSS and generates CTCSS itself if the repeater is active; the callsign beacon doesn't generate CTCSS.

The repeater is located that ESRAC, where also the 23cm repeater PI6EHN, the automatic bulletinstation PI8EHV and the packet node PI1EHV is located (the roof is getting quite busy!).

Since june 7 2002, PI2EHV is part of the IRLP network. IRLP makes it possible to connect the repeater with about 500 nodes that are currently part of the IRLP network (the number grows every day).

IRLP user manual

IRLP consists of two different types of stations: To use the IRLP node one needs a DTMF keyboard. Every node has a Node-ID, this is a 4-digit number. To make a connection with another node:
  1. Find the Node-ID of the node to be connected
  2. Key the transmitter, and identify:
    "This is PE1XYZ, I'm making a connection with node 1234".
  3. Key the 4-digit Node-ID
  4. The repeater will confirm the command and build a link.
  5. Make the QSO. Please key your transmitter for one second before talking, and leave 4 second pause between transmissions.
  6. There is a 3-minute transmission timeout. If a transmission is too long, the connection will be shut down and will need to be re-established.
  7. After the QSO, ID again and disconnect with the code 73:
    "This is PE1XYZ, disconnecting the link", and dial 73.
When the repeater has an active IRLP link, it will transmit a short beep after each transmission to remind folk that a connection is active. When the connection is with a reflector, then the repeater will gove two short beeps.
If you hear one or two beeps, then please remember that there is an active link and dial 73 before starting a local QSO! Starting a local QSO gives a lot of confusion when there might be as many as 50 repeaters listening in ;-).

With some American repeaters, the use of IRLP is restricted to members of the radio club. For this reason, please do not discuss IRLP commands if a connection is active!

Courtesy of the packet radio committee, we now have a 'live' picture of het repeaterrack.
PI2EHV is located on the top three shelves of the far right rack; you can even see the LEDs that show the status of the IRLP node. There are also other webcams which can be found here.

During buildup, as well as with current operation, I owe many thanks to the many people who contributed to the repeater, such as the original builders PA0JMV en PE1ABY, PA3CEG, Technical University Eindhoven, ESRAC, Amateur radio museum Jan Corver, PA0SHY, PE1DNA, PA0IB, PA0SON, PD0HOT, KH6FV, the IRLP group, and many others.
