I want to make a contact with a ham who is far away (>10,000km). How would I intelligently plan a scheduled contact to maximize possible success?
- Both stations have optimized their configuration for each band (maximum power, good antenna, capable of trying both long and short path azimuths)
- Both stations are capable of multiple HF bands, without a requirement that it be on one specific band (e.g. I don't need this contact just for a 80m phone award)
- I want to maximize the signal to noise ratio
- We have an accurate time reference for coordination (e.g. GPS clock)
- We are trying to make a voice (SSB) contact
- We can have written correspondence
How should I select a time, band, and frequency to maximize the chance for success? Is there any procedure or protocol that would help?
