New member and a couple questions
I am new to the group and very interested in making my first QSO via Satellite radio. I am in the Kansas City MO area and enjoy local simplex/repeaters, HF, and digital. Anyways, I have two handhelds (Anytone 868 and Yaesu FT60) dedicated at the moment for satellite use and just picked up an Arrow Antenna (146/437-10 LEO Satellite Antenna). I have yet to make a contact and just a few minutes ago I managed to hear SO-50, but in all the excitement I forgot to adjust for the doppler shift. It was busy and waited for a break to call, but that didn't happen.
I tried the ISS earlier this morning, but never heard anything. Will I hear anything if the astronauts are not on the radio?
I attached a screenshot and I believe I have a good concept of the AOS, TCO, and LOS. I did have a question on elevation according to this attachment. If the satellite was directly overhead (center of screen) it would be at 90 degrees? I added green numbers which I believe would relate to degrees in elevation. Am I on the right track?
What is Mean Anomaly?
Thanks so much...

WELCOME to this exciting aspect of our hobby. YOU ARE SO CLOSE to
>> … Anytone 868 and Yaesu FT60 …
I think the FT-60’s receiver is a little more sensitive … BUT - You are
using an antenna system with a lot of gain! Working ’50, ’91, and ’92
will be easy!
>> … Arrow Antenna …
WITH or WITHOUT the diplexer?

No biggie … just tune a little ABOVE to start the pass … then to the transmitted
frequency … then slightly BELOW as it descends …
SO-50’s 2M Uplink - NO Doppler correction.
>> …I tried the ISS earlier this morning, but never heard anything.
Nope. Not FM voice … but Packet is up!
>> … What is Mean Anomaly?
Huh - you SHOUDL know that. It is Question 1,234.789(c) in any exam …
It represents the fraction of an elliptical orbit's period that has elapsed since the orbiting body passed periapsis …
You DON’T need to know this … seriously!
Do NOT use that program's frequencies ... stick with the proven chart on the
front page at work-sat.com ...
