RUSSIAN 160m DX Contest - RU3AX Memorial RULES' 2023

Dear friends! We are happy to invite you for participation in Russian 160 m DX Contest (RU3AX memorial) which will be held on December 15 from 17.00 to 20.59 UTC, 2023.
Some important changes have been introduced into the rules of the contest:

1. QSO points will be scored in proportion to the distance between the stations which is of crucial importance for contacts made on the Topband.
To provide this the exchange numbers now will include the first 4 characters of the QTH-locator. In the opinion of the contest committee this is the fairest way of scoring the QSO points to satisfy all the participants.
2. The participants will compete in 4 different groups according to their location including a separate group for the participants from Asia (outside of Russia) and Oceania.
3. The contest will be divided into two tours each lasting two hours which will provide more dynamism to the operation. Within each of the two hour tours the participants will have time to operate in both CQ and S&P modes.
4. Our new contest director now is Andrey Kazantsev, UB7K.
For now you still have some time before the contest to check your RX and TX antennas while the sponsors are getting ready with the awards. You should remember that for many 160 meter band enthusiasts from ex. USSR countries it was one of the first contests , to bring up several generations of topbanders.

We are waiting for you at 17.00 Z on December 15, 2023.
We are sure you`ll have lots of fun! We invite all of you to take part in the contest and to remember our good friend Boris Grigorievich Stepanov to honor his memory.

Boris, RU3AX
One of the most famous and respected radio amateurs in ex USSR, Russia and Hamradio World.
