Re: [amsat-bb] RS-12/13 Testimonial

["Michael Kingery" <mkingery@xxxxxxx>]

I will 2nd what Jerry is saying about RS-13.  Incredible downlink signal.
In the evening for a majority of the pass I can turn the output power of my
847 all the way down to minimum.  I am using a 3 element tribander for the
uplink.  Overhead passes pose no problem at all.  QRM has not been a problem
for the night passes so far.  Hope to hear more stations on the bird!

> Yes, Bob, you have discovered one of the best kept secrets in amateur sats
today.  It is a phenominal signal--very clear and easy to copy all the way
to the horizon.  It is as loud and clear as SUNSAT, and that is saying a
lot.  Unfortunately, few people show up for the show.  Last night I was
lucky to get into a 5-way roundtable with KE4AZN, AC3A, KK5DO, and KD8UJ.

with just a "split" rig.  I run a FT-100 without hearing my downlink.  The
passband is slightly off-center by a couple of kHz, but you could use these
as fair "guesstimates" for trying the bird...

this fine LEO.
