K3: Attn Field Testers

[DOUGLAS ZWIEBEL]

Dear Field Testers,

Lyle referred me to YOU!

I recently inquired about how the SWR is displayed.  The answer is now
part of the FAQ.

This is a really exciting method (nice "trick"), but I have a
question, perhaps a concern.

If I'm on CW and doing 40 wpm QSK (common for me), is the DISPLAY (S
meter // RF/SWR) going to "flicker" at 40 wpm as I go from TX to RX?
Can the display "keep up?"

Should I assume that there is some sort of "delay" (user settable?) so that the
display doesn't go "crazy" during QRQ QSK.  Yes?  Some other solution?

Thanks,
de Doug KR2Q

At very high code speeds the SWR and power bargraphs will stay on
between code elements. This becomes necessary above a certain WPM rate
because LCDs have a finite switching time, and we want to avoid
flicker, which could lead to misleading bargraph readings. The receiver
will still recover between code elements if you're using full QSK.

I hadn't thought about making this user-programmable, but that's
possible.
