In the past couple of years, I have set up a very cheap satellite station
for mode B. I had a 2 meter all-mode mobile rig (FT480R) I paid 50 dollars
for connected to a cushcraft 4 element Yagi beam. I purchased a 70
centimeter FT790RII for $125 and made a homebrew 8 element Yagi.
Antennas are monted on single azimuth rotator mast and angled up about 10
degrees. This setup works extremely well for hamsat (VO-52).
Now, going from LEO hamsat to HEO Eagle, I will probably have to make a
longer UHF yagi and add an amplifier, Also a longer VHF beam. I already
have a mirage 2 meter amp with built in preamp. If the coax is short as it
is now, I can use the amp's preamp.
I saw a reference in one of the flurry of emails mentioning a 1KW ERP SSB
station for eagle. Right now, for UHF, I'm at about 250 watts ERP. Either
adding an amp or making a new antenna will bring me up to 1KW ERP or more.
Am I on the right path?
Will I be able to add to this equipment to work Eagle or will something
totally new be required for mode B ?
Thanks for ideas, Patrick N2OEQ
