The other morning I attempted AO-85, listening to the down link on 145.980. I just sat down and listened to the recording of that pass. At the time I thought I was not making it into the sat, but upon listening to the recording I found that I indeed was making it, and at times quite strong. I was using the Arrow, two FT-60's, and headphones, but during the pass I could have sworn I was not making it, as I was not hearing myself...just squelch. I did learn from that pass though that AO-85 was much clearer on 145.975 in the latter stages, or after it passed the posted Max El for that pass.
Just wondering if anyone else experienced the same scenario as I. I did tweak a few things with coax and radio programming last evening, and that seemed to make a noticeable improvement on the SO-50 (03:07Z) pass last evening.
Have a great day everyone,

A handheld receiver will sometimes be a little too sensitive with this type of configuration where you are using the same mast for the UHF and VHF antenna together. The front end of the receive HT will have a tendency to be a little desenced causing a slight reduction in audio quality on your downlink. This might be what you were experiencing.
What were you using to do the recording? Was it not the same radio as what you were listening to for downlink?
