The Dutch Vereniging van Radio Zend Amateurs (VRZA) is preparing an anniversary activity to mark the 75th anniversary of its founding. The QSO Party will take place on Sunday, November 22, from 13:00 to 16:00 local time. During this period, stations using special callsigns with the PI75 prefix are expected to be active on the bands. For radio amateurs, this will be an opportunity to contact the association’s branches and groups and celebrate together at club stations.

VRZA was founded on November 23, 1951. This year’s activity will launch the organization’s anniversary year. It will not be a contest: participants will not exchange contest numbers. The organizers have planned activity on the 2-meter band using SSB and FM, as well as on the 40- and 80-meter bands. The announcement specifies the ranges 7175–7200 kHz for 40 meters and 3650–3750 kHz for 80 meters.

The event includes an award „75 jaar VRZA – 36e VRZA QSO party 2026”. The requirements have been adapted to the one-day activity: to earn it, operators must make contacts with eight PI75 section stations on the HF bands or with four such stations on VHF. VRZA listed twenty anniversary callsigns assigned to branches and groups, including PI75ADH, PI75EHV, PI75GN, PI75VRZA, PI75TWN and PI75ZWN. The organizers encourage club stations and individual operators to participate, hoping for broad activity from the sections.

For Polish radio amateurs, this will be an opportunity to work stations from various parts of the Netherlands as part of a single, clearly defined activity. It is worth watching for PI75 callsigns on the bands and checking the award requirements before starting operations. In this way, the VRZA anniversary combines on-air activity with an opportunity to learn about the structure and geographical reach of the Dutch association.
