Re: HELP!!!! - Major Frustration



50' of high loss coax...I'm not sure you will hear anything, especially with
the power often turned down quite a bit.

As an example, I've been listening on an alternate system, a J-Pole at 65'
in in the clear, at the end of 115' of LMR-400 coax. No preamp. I have
copied VERY, VERY few packets from ECHO. On a Right Hand Circular 14.5 dBc
gain antenna up only 8', I copy lots of packets with 80' of LMR-400, no
preamp.

50' of RG-8 mini has a lot of loss at 435 mhz. With nothing but a make shift
ground plane, you may not see many packets with the satellite running very
low power much of the time. Indeed check your keplerian elements, but if
they are correct, then try the suggestion below:

Do you have a mobile rig that can listen on 435.150? If so, when some of the
passes come this morning, go to your car and listen there. Coax loss would
be much less of a problem.

At the beginning of the pass, listen on 435.160.
In the middle of the pass, listen on 435.150
At the end of the pass listen on 435.140
