Christmas 2021 BATC Repeater Activity Contest and Activity Challenge

The Christmas Repeater Contest 2021 will run from Friday 24th December 2020 through to Monday 3rd January 2022 inclusive. The aim is to increase ATV repeater use. On offer is a £100 prize for the repeater group with the most contacts recorded.

The on-line entry and ladder system as used for last year's Contest on the BATC website will be used. The Ladder has fields for you to enter the points claimed and the repeater's callsign. Contest Ladder

As well as the Repeater Challenge, you are invited to enter any non-repeater contacts you make so that the Contest becomes an Activity Ladder Challenge too. There are no prizes for the winner of the Activity Ladder Challenge but the first and second places will receive a certificate and your name and callsign will appear in CQ-TV with attached bragging rights, kudos etc.! Many repeater groups have found that their income has been slashed by the pandemic precautions, so here’s a chance to help your local repeater group and stir up some activity.

The rules are available in PDF form here: File:Christmas 2021 BATC REPEATER CONTEST- ACTIVITY CHALLENGE RULES.pdf and are reproduced below. Note the rules in the pdf document are the master version. The wiki text below may have been changed for clarification.

You can claim points for working the same contacts on each day of the contest. For the Challenge, on any day you may work the same station on different bands and claim points for each contact.

Contacts from multiple locations are permitted on the same day, band and with the same callsigns. For example you can work into the repeater from home and then you can go out portable to two locations and all of the points earned /p can be added to those claimed for working the same stations on the same bands later in the day from the home station. RF or Internet links between two repeaters do not count for additional points.
