Our GB3MCB six metre beacon was chosen some years ago to be part of an International Beacon Project. This involves five beacons operating on the same frequency (50.005MHz). Each beacon will transmit for a one minute slot, every five minutes in synchronised timing slots. The five beacons involved are EI0SIX, IW9GDC/B, PI7SIX, GB3MCB and OZ4BHM. As GB3MCB is now licensed for dual frequency operation it will operate for the intervening four minute periods on the original frequency of 50.443MHz.

The new six metre beacon was given to our group last year by the UK Six Metre Group. It runs a mode called PI4.

You can download free software to decode the PI4 mode from http://www.rudius.net/

PI4 mode transmits a one minute cycle:

First it sends PI4 coded call sign for 24.33 seconds Then there is a pause for 0.66 seconds It then sends CW identification (call sign and locator) at 12 words per minute for the next 25

seconds followed by a 0.5 sec pause Finally, it sends a carrier until 59.5 seconds ending the minute with a 0.5 sec pause.
