[Elecraft] P3 first look

Refresh rate as shown is 6 frames/sec.

Keep in mind that the firmware is not finished (according to Wayne) and it will
only get better (like our K3s!)

>> 
>> It looked real nice sitting next to the K3. Display 
>> resolution is the first thing that I noticed, very high. The 
>> P3 and K3 were both propped up on their front bails. Having 
>> both units the exact same depth makes them match perfectly 
>> when sitting side-by-side. The prototype I saw had smooth 
>> black sides that matched the K3 finish. Wayne says there will 
>> be ventilation holes in the top of a production version. From 
>> Wayne's description, maybe 2/3s of the interior is open space 
>> for unknown future expansion ideas. 
>> There is a knob on the front to move the frequency cursor. 
>> Buttons are there on the right side of the display to change 
>> modes and select how much of the IF bandwidth is displayed. 
>> Up to 400 KHz and down to much tighter spreads. If I were 
>> operating CW on 40M for example I would probably be looking 
>> at a 30 KHz spread that covered a little bit more than the DX 
>> window. Other times I can imagine watching a much larger IF 
>> window, such as 10M phone.
>> 
>> When I walked up the P3 was operating in split display mode 
>> with a waterfall on top and spectrum plot below. The 
>> waterfall is quite sensitive to picking up weak signals. I 
>> think it was Jim K9YC that said that his panadapter has led 
>> him to find all the troublesome wall warts in his house and 
>> quiet them. I can fully believe that this is going to be a 
>> result of many users of this technology as you will find all

>> 
>> I asked if the P3 will have independent audio out (say of the

>> The P3 sure has a wow factor going for it.
