It seems to be working about as well as one can expect.
Remember the current setup is not a true cross band repeater with cavity filters and a tight set of receiver crystals.
It was very choppy over boston as the number of users increased.
It seems that stations that were running Power and compensating for Doppler had greater success.
The Doppler correction seems to be one of the keys to getting in.
As for your Audio, you must speak softly. There is one specific VE2 station that is running a lot of ERP, unfortunately his Audio is too loud and as a result his audio is pure distortion. After 3 orbit passes I still cold not figure out his call sign because his Mic gain was too high for this satellite.
I am also hearing many people using Full Duplex systems, who forgot that you MUST be wearing Headphones while using Full Duplex. The Audio loop caused by Not using the headphones also makes your audio Unusable. The audio circuit in this repeater is TOO hot and will distort easily.
Tips:
Use the minimal power. Compensate for Doppler on 437.800 (plus and minus 10khz) Speak Softly and slow Full Duplex users must wear headphones.
And also you signal will not decode until you are at least 6-12 db above the noise floor at the Space Station.
QRP stations may want to plan for OFF hours when most people local to you are Sleeping or at Work.

Signals on the cross band repeater is very choppy. Is it a problem? As i far i can remember i never hear the ISS downlink so choppy. Is the COR system is activated with audio in the signal or only by the carrier?
Thank's
