To take this a step further. Why not consolidate all the different gear
firmware programs into a single program? First screen would be to
select the device.

As you say your are a casual CW operator. Perhaps some feedback from a
nearly 100% CW operator of 50+ years would be useful too.
1) Tuning 400 Hz
2) When things get tough 200 or 250 Hz. The utility of the 200 Hz
signal has been especially good for pulling out really weak ones on 15-6M.

QSO's at the same time. Thus a violation has occurred.

Guys,
I'm also curious about this-- especially what's going on on 15M.
My values at 500 W out into a dummy load are:
(amp), [volts], {efficiency}
1.8MHz DC (11.5) [63.1] {70}
3.5MHz (11.2) [63.5] {71}
7MHz(12.2) [62.5] {67}
10.1MHz (not measured)
14MHz (13.4)[61.8] {

The mobo I had also had an LPT port pin connector on board. The only
difficulty was that it was a non-standard sized connector and the pin
numbers had different functions than usual LPT connectors.
Also keep in mind there are at least two standards for the pin
numberings on the onboard mobo co
Don,
It isn't the 8ms that is relevant, it is how the K3's coding behaves in
subsequent CW characters when the TXDLY is varied from 8 -20 ms. PTT
is irrelevant.
Higher values produce QSD regardless of how the amp is keyed. It occurs
regardless if one is using the K3's internal keyer or an e
Why are contests so popular? Think of three factors:
1) Competition and station performance testing.
2) Weekends are the only time may people get to operate much. The
desire is to make a lot of contacts.
3) Rag chewing in the everyday world has gone the way of speeches vs
tweets. So short exch
It isn't a signal report. It is really a place holder to let your brain

For those who don't believe Dave, here is some suggested reading material.
N6BT's new Antenna Book, Array of Light
He discusses the significant difference an extra 2db makes.
Yes he also sells antennas, but what he says rings true.

I wonder if anybody else is observing this.
The first few CW characters do not develop full power as indicated by
the LED power displays.
My gut feeling is that LED power displays should be fast enough to
capture the "true" power for even the first couple characters.

I don't think the majority of contesters and DXer K3 owners agree with you.
