Just reading the mail and wondering how the signal compares to the beacon
just after launch of AO-51? I was able to copy it fine with a 1/4 2m WL
mag-mount whip on a square of sheet tin. I did find that the use of a 440
MHz preamp help a whole lot!
I am asking since my tracking satellite array will not be set back up at
our new QTH till next spring. In the interim I was going with the 1/4 WL
whip+preamp for UHF and a turnsile for VHF.
Interested in comments.
