Joe, I would hope that the enhanced 75-bit message structure will allow for the Tx3 and Tx4 messages to contain all of the 0-9 and A-Z characters. This would allow FT8 to be used in a number of other operating events & contests such as State QSO parties and Field Day exercises. Can we

About a year ago a VHF contest mode was discussed and the NA VHF contest mode was implemented. The Region 1 contest VHF mode was specified, but is not yet implemented. Each morning there is a fair amount of MS using MSK144 going on on 2 m in Europe, see www.on4kst.org/chat/login.php?band=2 FT8

Hello Joe, As for FT8 for contest, you got it right. What you describe will do for Reg 1 VHF-UHF-SHF contests. Contests using special exchanges like membership number will have to use the free format for them. It would be nice if the program could figure out when the QSO partner is using contest

I dont as I no longer enter contests, But Ian gave you figures which showed 1% , BUT as I said those figures will be much higher from central Mediterranean area. taking imperial figures before a mode is used in vengeance in a contest, is IMO not going to allow for increased activity. FT8 allows

A further note Ians log was I suspect from N W Europe, if you draw a circle of 1000kms centred on Rome , , Italy, that will cover the mot prolific use of complex callsigns, The Italians have similar regulations to those in Austria, and are in range of most of the Adriatic and Mediterranean

Hi Joe, Sorry, I missed your original message. I've just taken a look at a list of stations that were active in the 2017 June 50MHz IARU Region 1 Contest. There were at least 30 stations with this format of call sign. Over 3000 stations were active in this contest. 73, Ian G0FCT On 28 July 2017

It could be a considerable amount Joe, Some countries in region 1 are small. I Europe you can easily drive thru 5 countries in a day, And if you are in the Balkans area you can do it in half a day. For VHF its very common for high ground suitable for contest operation to be just over the border.
