Friends, I think some of what is being overlooked is the effective range of QRP under these solar cycle conditions, and the fact that most antennas are not at optimum height, and are not unobstructed.
For the USA let's keep it simple and focus on 7.178 BITX QSOs, and alternatively 7.285 QRP calling frequency. With minor adjustments as needed. And 7.277 could also be a third option.
With these days, times, select?frequency options, successful contacts with other BITX operators is almost solidly assured. DX contacts might?require more flexibility in frequencies, and modes.
And finally, other regions or countries can decide on what works for them, and I bet KC8WBK would include them in his weekly schedule announcement. How much global coverage does this group have anyway? Are there other language BITX groups?
