Hello Amsat list,
Sorry for the repost. I see a copy in the archive, but I
didn't get anything by email.
I'm a new list member. My call is AE6RV. My radio is
an FT-726R with a couple of Mirage bricks. My antennas
are: a turnstile on 2m and a turnstiled moxon on 70cm;
both in the attic. I don't have any preamps yet. I've
been working just the FM sats lately.
I have a question about polarization switchers. Right now
I don't have any and suffer pretty bad fades. I seem to
be frozen by "analysis paralysis". I'm thinking of using
the Omron G5V-2 relay in a simple switcher with the
contacts paralleled. As I'm running less than 100 watts
at the antenna this looks like a good choice - I think, or
should I be looking at something else? My budget is limited,
so expensive relay setups are out of the question. If anyone
has a link to a good homebrew switcher for 70cm I'd
appreciate seeing it. Maybe I'm making it too complicated.
Bob - AE6RV
