Good qso. ;)
The great national qso of channel 27 (27,275 Mhz) of Friday night, Saturday night & Sunday morning is at the initiative of the various regions to promote local qsos. In FM, am or USB & lsb depending on who's remoteness with a possible qsy depending on the modulation that could be there. All of us, therefore, are making calls on this channel. In am, Blu or fm and this from 21 pm (for Fridays and Saturdays). And from 10 am to about 12 pm (for Sunday morning) ;)

I'm not sure about about having all modes on one calling frequency as this will no doubt cause a lot of interference but it's still worth a try I guess.....
