[TangerineSDR] [HamSCI] Grapes Funded for 2023/2024 Eclipse Study

Tue Aug 2 17:15:58 EDT 2022

Hi Ward,

  Is that why all these west coast hams (like N6QW) are repeatedly pointing
to no DX at all on their radios and saying "Cycle 25 is a Bust"?  I'm
getting very very tired of trying to answer these questions and have
essentially given up.  Maybe you can help me by pointing to something,
anything?
