NRAU Contests in general

Please note: All NRAU Contest related information herein is under revision …

The NRAU is the responsible entity for two amateur radio activity related contests, namely the NRAU Activity Contest, or the NAC, and the Scandinavian Activity Contest, the SAC.

At present the question is how much of this information, or details, should be published on the NRAU webpage.

The rationale behind this hesitation is that more member society webpages already cover this, although in their native language. And, there is no rationale to copy or duplicate what is already found other places.

However, at the same time, the NRAU needs to ensure that the basic contest information and/or rules can be easily found, and ensure that this is available in English.

NRAU Activity Contest – NAC

The NRAU Activity Contest, or the NAC, is a laid back contest to promote usage of our amateur bands from 10m and up.

Until the source rules for the NAC have been identified, these are the scheduled contest bands and days:

Scandinavian Activity Contest – SAC

Please note: Contents is under revision

The Scandinavian Activity Contest – SAC started in 1959 and has evolved a lot since then. It takes place twice a year, both on CW (telegraphy) and on SSB (telephony), using the five original shortwave bands dedicated to amateur radio (80, 40, 20, 15 and 10m bands).

General information on the Scandinavian Activity Contest (SAC) can be found on the SAC webpage.

But, what does SAC have to do with NRAU?

Well, §15 in the SAC rules clearly states that:

The Nordic Radio Amateur Union (NRAU) is the organizer of the contest. The member societies of NRAU are EDR (Denmark), FRA (Faroe Islands), IRA (Iceland), NRRL (Norway), SRAL (Finland), and SSA (Sweden).
The contest is administered by a committee composed of one member each from Denmark, Finland, Norway, and Sweden.
