[Elecraft] P3 VFO B marker.

[Geoffrey Mackenzie-Kennedy]

Hi Alan,

I see that there have been some wishes expressed on the List about marking 
the frequency of VFO B on the P3.

FWIW the scheme that I used with my old homebrewed panadapter (now retired) 
was to mark the frequency of VFO B by a vertical line, which ran from the 
top to the bottom of its spectrum display. The main reason for making the 
marker line so long was to prevent it from disappearing should some very 
strong signal land on the same frequency as that of VFO B. The problem with 
a typical inverted delta marker is that it can be difficult to see in the 
heat of battle, and it will bounce as well of course.

I use the same type of marker for VFO B when using my Perseus as a 
panadapter, which has both a spectrum and a waterfall display.

73,
