Re: ECHO telem--"empty" .csv files?



Hello Mark & BB,

Yesterday I was only seeing TLM data about every 30 seconds on 00:16  and
00:46 of each minute .
There was quite a bit of testing going on with various systems on the
satellite.

Today I was receiving TLM data about every ten seconds 00:24, 00:34, 00:44,
etc.  as system testing continues.

You may also miss these if a fade occurs during the periodic TLM
transmission.  I have greatly improved my TLM reception by adding a pre amp
(even though it is in the shack). Today's pass was also using 0.6 Watts.

I am tracking the satellite with a 14 dB gain 70cm antenna.  Those using
verticals and small gain antennas will get some signals, but probably not
decode consistently during the pass.  If you have a DCD light on your TNC,
if it is not solid you aren't correctly decoding all the data.

Regards,
Gould
