[Elecraft] Couple of questions on the P3

[Phil Anderson]

Recently added a P3 to my K3 station.....nice....yet questions:

1. Wonder why the spectrum display gets noisy when I tune VFO A. A few 
have said that is expected and suggested that one make sure the screws 
on the K3 and P3 case are tight. I'm assuming that when one tunes VFO A, 
the FFT in the DSP gets lots of extra data and the display is noisy as a 
result. Once I stop tuning the VFO A the spectrum display goes back to 
averaging as expected.
Hm?

2. I purchased the SVGA card and it came installed in the P3......have 
been successful is connecting my computer through the RS232 port on the 
P3 to run both the K3 and P3 utility programs. Also the big display and 
the P3's LCD are working for the most part. Ok there. Now, is it 
standard for the external large display to not allow markers in the 
waterfall area? When I use the P3 menu and turn waterfall markers on or 
off that works for the P3 LCD. However, there is not marker shown in the 
waterfall area of the big screen attached via the external display jack. 
Hm? I can live with that but is that right?

3.  Is anyone aware of an article on the web that goes into the "why" of 
how the cursors and makers were designed to do what they do? Perhaps 
things would be easier to follow then since there are a very large 
number of "tap this or hold that" combinations available. I realize that 
to tap or hold increases the number of actions that each switch/etc can 
do, thus cutting down on the knob count on the front panel.

thanks, Phil, w0xi, KS
