[Elecraft] P3

[Brian Hunt]

Hi Jim,
I’ve discovered that it’s easier to see a very weak signal on the waterfall than in the amplitude plot. Setting the SVGA screen for 25% spectrum and 75% waterfall gives lots of space to see dim traces. You may have to adjust the threshold a bit. 

73,
Brian, K0DTJ

>> Hello all,  Having acquired a fully loaded K3s fairly recently I am behind the curve of those fortunate enough to have a K4.  Its taken several weeks to get a decent handle on the K3s and now on to the P3.  I have all the manuals including Fred Cadys K3s and P3.  I find the K3s to be excellent and pretty remarkable compared to the many other transceivers I've owned over nearly 50 years.  The P3 has the vga board and is connected up.  All is well Except;  weak signals do not show up on the P3.  I can hear a rather weak signal but nothing at that point on the P3.  My thought is at this point the P3 is not doing me much good looking for a weak dx signal.  I have to think I have something not set up right etc..  Any help on what I'm missing would be appreciated.Thanks,Jimk2hn
