until further notice. Until I can figure out what I am doing wrong.
Thanks Jon, Lloyd, Mike, Jay and whoever else may have been trying to
copy the signal.
What I am receiving here on SpecLab's vector display is not what I think
it should look like after reading more about the mode. If I now
understand correctly the vector display should only show the signal at �
and 18� degrees. The signal I was transmitting has many vector lines
appearing to be random. But SpecLab is able to decode the signal
locally after doing fine tweaking of the receive frequency. The signal
shouldn't be as hard as it is for me to tune in so I suspect this
indicates a poor modulated pattern.
I am modulating with a the same RF setup I use for JASON. The generator
is the LO at 5000 Hz lower (172.700 KHz). IF input is from the sound
card which is the modulated 5 KHz signal. The output of the mixer is
filtered to remove the image which leaves the 177.700 KHz desired
signal.
Any suggestion will be appreciated.
