AO-40 update

As the table below demonstrates, the mystery effect has taken A0-40 into highly unfavorable ALON. Attempts at communication are likely to be futile until conditions improve in early and mid July. Note that unfortunately
optimum squint in late July corresponds with a very bad solar angle….stay tuned.
