|Emission mode||USB; BFSK, 100Bd/620Hz, ACF=16|
|Known counterpart stations||E11, G11, S11, S11a, M03, F03, P03|
All F11 schedules are weekly, follow year-round UTC (no DST adjustments), and use three different frequencies depending on the month - one for November to February, one for May to August and one for the remaining months. For most of the time there is no traffic, and one random week of the month a message is sent that always consists of 20-50 groups (excluding "88888"). Those always have a repeat transmission in the same week.
Each F11 transmission is followed 5 minutes later by a repeat of it on the same frequency. 10 minutes after the repeat, an E11 or S11a transmission comes up, carrying the same message, always on a nearby frequency, normally up to 1 MHz away. However, not every single analog schedule has a digital equivalent.
