I was looking at the PX3 this morning, listening on 40m, and you could make a
small display change to do #5 (well the second #5).If the moving 'tick'
marks at the top of the display went down instead of up, and the top line of
the display was 'thickened' representing the full band, then the display
window could be shown as a light green section of the band. The same as the
rx bandwidth is shown on the center cursor. As you tuned in the band, the
green visible bandwidth within the full band would move giving you a sense of
where you are within the band.
And I'm probably just in experienced with the PX3, but how do others tune to
get something seen near the noise ? Often I see something to check out, and
once I start tuning for the signal I loose my context and either undershoot or
overshoot the faint signal i was looking for.I understand the use of the
Markers to so this, but just to do tune / look I us
