Good question. I always post alerts with estimated timings and frequencies usually two days before my activation.
Usually my method of operating is to scan round the band 40m or 20m to see what activity exists then call cq. If I get contacts I ask if they can spot me. If no contact after 5 to 10mins I will self spot via SMS.
I operate qrp 5 watts ssb sometimes 10 watts with external battery and on many occasions I have not had a phone signal and this has resulted in no contacts which is frustrating radio wise although the hike is always enjoyable.
Considering there are many chasers out there I work as many stations as I can and continue calling cq until either my time is up or my bones get cold before going qrt. Without self spotting I believe i would not have activated many summits since I started sota in 2015.
Thus in my view it is a fair means to get noticed when activating summits.
