P3 display of K3 filter bandwidth and other information

[wayne burdick]

The P3 is connected to the K3 at a point ahead of the crystal filters,  
so when you change crystal filters on the K3, it won't change the P3's  
displayed waveform.

However, the P3 will be aware of the K3's filter bandwidth and offset,  
so we can show a bracketed or otherwise highlighted area on the P3  
display that reflects the filter settings. We could show both the DSP  
and crystal bandwidth using different colors.

Going farther out on a limb: The P3 could highlight ham-band edges and  
band segments, even by license class, programmable by country. It  
could mix spectral and waterfall displays with decoded text. You could  
assign a function switch as an auto-tune switch for PSK31 -- etc.,  
etc. (Somebody stop me!)

I like the limb you're out on.

Will there be a cursor function, similar to a spectrum analyzer - or
does the P3 auto-center frequency in the IF center?  If the answer is
yes, text display of peak/average dB of a selected signal could be
done.

Maybe the cursor already exists and I just didn't see it on the face
of the engineering unit at SB.

Both.

Yes.

It wasn't turned on. Actually there are two cursors, one for the main  
RX and one for sub.

We'll have a lot more to say about P3 operation in coming weeks. We  
have "a bit" of work to do....

Or perhaps a small area on the screen that provides the information that is
fleeting on the VFO B area.  Such as power out, bandwidth, CW speed.  Maybe
a small dashboard where users can define what values they'd like displayed
much like some of the older Garmin GPS's used to work.  

This is where the term shoot the engineer came from..

Wonder if the graphics library (if you're using one) supports
transparencies.  That could lead to some really cool filter BW displays.
Especially for the DUAL PB setups.

It's a good thing that you have Al involved on this.  You are already
busy as can be.

Be sure to let me know if you can think of any way to use CW regr
extended or another program for testing.  I'll try my imagination on
this, but it would seem to require a sig gen and some way of dumping
the display memory...  Er, maybe it's simpler than that.  Like
eyeballing it.

- Mouse connection to the P3 to point in the P3-display and shoot, My
number one!

- Keyboard connection to P3 to type something --> K3 will send CW,
PSK31, RTTY, or what say you.
- Take out the computer: config the K3 through the P3 if mouse and
keyboard are connected.
- freq-entering via keyboard

Wayne:

Will the P3 use an 8 MHz BPF and buffer amp, followed by a quadrature mixer?
Tnx!
