[P3] Seeing my CW TX signal - beta 1.08

N7US
Using beta 1.08 I'm seeing my CW signal on the P3 as I'm transmitting with
my K3.  With a pitch of 350 Hz I'm seeing it down 700 Hz from the center
frequency using a span of 2 kHz.  When I switch to CW-R the signal appears
to be up 700 Hz.

I changed the pitch to 500 Hz, and the signal now is up 500 Hz from the
center in CW-R and down 700 Hz on CW, which is obviously not twice the
pitch.

The amplitude seems to be independent of power.

I don't remember seeing this behavior with 1.05 but I might not have noticed
it.

Transmitting a carrier has no display, as I would expect.

Jim N7US

Yup, it's on the bug list.
