At my age [70s] I’ll not sit there calling CQ for 10 minutes especially in winter. I’ll call CQ and listen 2 or 3 times for about 2 minutes before QSY’ing to another band or going into hunt-and-pounce mode or going QRT. I cool down quickly just sitting in the cold no matter how many layers I’m wearing.
If a chaser really wants to work that particular summit they need to be monitoring for a self or auto spot starting a bit before my alerted time. Monitoring my progress to the summit on aprs.fi is a good guide. I’m sorry but my schedule, comfort and safety come first.
