Howard,
I should have been clearer in my reply to Rick's e-mail. Rick discussed using
an M2 Orion 2800 or a prop-pitch rotator with the MonstIR.
The M2 2800 Orion rotator has insufficient capacity to hold the MonstIR in a
moderate wind, while a prop-pitch will handle the MonstIR easily under any
conditions that the MonstIR can survive.
I did not intend to make a comment regarding the Yaesu G2800DXA, and I'm sorry
my e-mail wasn't specific enough to avoid unintentionally interpreting it that
way.
73!
