2. I disagree that 5 watts to an Arrow is "not enough for an analog
sat" as I've never run more than that and have over 1,600 QSOs in the
log over the past year and a half on the linear transponder satellites
(including many at elevations of 5-7 degrees to Europe and elsewhere),
but you are right that it likely isn't enough to control a big DX
3. A split is good, but difficult to implement when you are relying on
hearing your own signal.
