The best technique is to use a narrow filter. 250Hz/500Hz is essential and if the weekend pile ups are too big to handle, then teach yourself how to work split frequency. This method is fiddly using menu driven transceivers like the FT-817 so it must be mastered and practiced at home rather than on a hill if you haven’t used it before.
VFO A on 7032 to transmit and VFO B to receive on about 7033± 0.5 KHz to receive and spread out the callers. If you use this method make sure that the QRG around 7033 is not in use, especially by another SOTA activator, or you will not be popular.
If in doubt or the band is busy try to use 7025-7029 KHz instead of 7032. There is always plenty of free spectrum there. As SOTA becomes more popular on CW I feel this technique is worth mastering. Chasers will also need to learn the split technique - used of course all the time by CW DXers like myself. Listen on your TX VFO whilst the chasers are transmitting to the activator and you will soon find out where to transmit and make your QSO. Not everyone is good at this so if you hone your skills you will be successful.
I don’t advocate calling CQ by numbers on CW - the fading (QSB) has too great effect on SOTA QRP stations signal strengths to make this method viable.
Several chasing are too “macho” and call at a speed well in excess of what the activator is sending at. This is poor operating.
