[SixClub] [HoustonHam] FW: LIFTOFF!!!

[Chris Boone]

Thanks for the info Mark....I was going on what the last positions on the
APRS was by W5OMF and one other at the airport looking at the web site and
APRS Updates; In fact Geoff used Google Earth and determined they had landed
in some trees!! :) Evidently you got better info and of course, the
calculations are correct....either way it was SOME DAMN GOOD FUN!!! AM
WAITING FOR THE NEXT ONE...and I need to get a Tshirt or two damnit!!! :)
I want to do a 2m up/6m FM AND AM downlink.....so those with FM rcvrs can
get the noise quieting but the AM guys can stretch out reception as much as
possible! I am planning to do the same thing on a new 6m rptr I have coming
online...modified GE MSTR IIe with AM and FM xmit and may add a -1.7MHz
offset AM rcvr on it along with a -1MHz FM input..if I could figure out how
to make the main input do double auto detection of FM or AM and route that
to the rptr audio path I would!....been thinking a voter with the FM
detector determining if it was AM by having no/very little audio on the FM
side out may do the trick! ;)
