Please note that all four digits in the contest number should be different and not consecutive. The numbers must be different, e.g., these numbers are OK: 2741, 4820, etc, these are not:- 1111, 1138, 1381, 1234 etc. Reports should be sent using a 1-5 video quality report and a serial number, starting at 001.

For a video contact only, confirmation of reception is required by transmitting the sum of the code numbers (not the actual transmitted number) on the talk-back channel. Stations are encouraged to use amateur radio for talkback, but use of mobile phones or internet is permitted.

9. Distance Calculations. Your computer program should give 6371.290982 km as the earth’s radius and 111.2036 km for each degree change in latitude before rounding off to the nearest km. For scoring purposes, all valid contacts shall be deemed to have taken place over a distance of at least 5 Km, even if the two stations or the repeater in the contact have the same or adjacent locators. Scoring should be based on the distance between the centres of location squares, not map distance. Full 6-character length QTH locators must be used.

8. '''On-line logging'''. Use the 6cm Activity Ladder page on the BATC website here: https://batc.org.uk/6cm-ladder and fill in the boxes for each contact as appropriate. The website will calculate the points awarded for the contact and add them to your total. You can add contacts made since the 1st January 2022 retrospectively. '''Entries will only be accepted via the on-line Activity Ladder web page'''.

Use the standard rounding for decimals when converting distance to points. 0.5 and above add one point, anything less than 0.5 use the integer only.

9. '''Disputes'''. The decision of the contest manager and/or the BATC Committee is final.
  
−
Example: A station operates from IO93PV and contacts a station at IO93RS37 (distance 17.5km). If the checksum of the received numbers matches the sum of the number transmitted, the transmitting station will be awarded 18 points. If the contact is confirmed as two-way both stations will be awarded 36 points

10. '''Spirit of the Contest'''. Don’t leave your video transmission on any longer than necessary and don't hog the ATV calling channel 144.75 MHz; move off to another channel once the contact is established. Contests mean activity and good fun, join in and, even if you only work one or two stations, please use the Ladder to record your activity.
