[AMSAT-BB] Re: HO-113 passband edge test

      Yea that’s my impression as well. If we were to assume the center of the documented passband is incorrect and make it 10KHz HIGHER on the downlink 435.880MHz IIRC then the passband becomes symmetrical.

Hi John and all
Indeed, I have been able to verify that the upper edge
 of the passband is higher than the one reported.
In the AOS at about 8º I have been able to hear my return
 in 435212 khz with a uplink in 145844 khz.

I did a little test tonight and I think the edge of the top of the
passband is around 10KHz higher than published. Don't have time to do
the math on the bottom of the passband.
Is my math right?

I could have just zoomed out on the waterfall... oh well.
