Yesterday evening I get hands on the tools and eyes on the gear, and
manage to deduce a procedure to adjust the sensitivity of my RX rig...
This was great, just with a Digital Multimeter measuring the noise level
at the RSSI on the FI IC of the radio I squeezed the sensitivity of the
rig to it's maximum... (from 0.45 v at the original setting to 1.1 v
whit my setting)
There has to be a more efficient ways, buy whit the tools on my hand
this is the only way...
From not hearing any station with the 15dBd yagui to 3 contacts on the
night pass of SO-50 with only 13 degrees in the pass... That's a
So CO7WT is ACTIVE on FL11 in every SO-50 pass that I can work... My
setup is working OK now.
Thanks to N8RO, K4FEG and WA4NVM to be my first satellite contact on the
bird, LoTW upload in progress...
I will to be active today in the 1638Z pass if you want to make a contact.
