aaahh - you use LSB ;-)

I take the other sideband -> therefore up to 22000 Hz ...

Just had a 2 degr pass here and tracked to OBJ D and a fixed offset of 4
Could hear exactly 3 beacons without manually tuning (mhh, it's no big deal
with such a low pass...)
Beacon interval is now 2 minutes again.

73, Mike

If you can get the CW at 1200 Hz, the following telemetry burst will be
right on frequency, and decode every time.  Using MixW is a great way to do
this.  You just need to be very quick with the mouse.  ;)

DK3WN and I have both found that 2009-028D, NORAD 35004, currently gives
much better agreement, especially on Doppler correction, than the others,
including 35002 which CalPoly had on their site.  Based on the passes
yesterday afternoon, my current DOPPLER.SQF file has this:


Mike finds a slightly lower RF frequency, but that may just be calibration.
Except for one burst at an over the top TCA, the CW was within 200-300 HZ of
predicted the whole pass, and the telemetry program has able to handle the
slight deviation.
