This weekend finally we had action on 6m here in the JO33hg no go zone... Found  6m wide open when i started but i could not find the rules to N1MM logger i was not prepared for the contest I did not expect we would have a Ball at 6m I was confused about what contest was on and started VHF serial type since i heard exchange with serial given on the band.. And now Sunday  i still hear serial  exchanged Also a signal report is not needed as i see on the SMIRK side? Exchange  is callsign, SMIRK number, if applicable, and grid square. Partial contacts in which one of the above pieces of information are missing, do not count.  6 digit square ?  or is 4 digits okay too?  That would be my type of contest !   just the locator as real info.. Our  normally well informed contest calendar by PG7V did not mention SMIRK because that is not HF. Now later found SMIRK needs no serial number but optional a SMIRK member NR to double the QS...
