Re: AO-51 APRS Satgates

As announced on -bb, ANS, and the webpage, the digital side of AO-51 is in 
L/U 9k6 until Sunday night, when it goes to L/U voice on the 435.150 
downlink for 1 week.

Did some APRS testing via ECHO today...

I was unsuccessful digipeating via PACB-1 digipeater on AO-51
today (saturday).  I'm not sure why.  It was an overhead
pass, and I was getting good 435.150 +/- downlink.

It could be that I simply could not see myself because of the
lack of any TXdelay on the 9600 baud downlink.  This is a
known problem and why we always say it is difficult to see
one's own signal using the half-duplex TNC built into the D700
radio.  My previous tests had been using the APRS in my
car as the Uplink and then running in doors to watch the
downlink from the sat station.  I had seen some success there.

Today, the wife had the car, so I thought I would try
one-hand clapping mode...  Anyway, wonder if anyone
saw me?

Also, on my rig the downlink on 435.150+/- seems to center
a few KHz high during the pass?
