Sorry for the somewhat off-topic post but this is the first time I have
heard the Eico 720 mentioned in decades. I happen to have one if anyone
is interested in buying it.

Jim and all,
I agree, the *best* way to look at keying is in the frequency domain,
but for those who do not have that capability, the time domain keying
waveshape can be beneficial.
The P3 TX MON option does not show the frequency domain, but it can
display the rise time and fall time of

You've GOT to be kidding -- CW waveshaping is spectacularly good

Besides, the time domain (rise/fall times) is the wrong way to look at
keying. The only effective way is in the frequency domain, where the P3
with SVGA can resolve to a few Hz when set for narrow scan widths.
A spectrum analyzer is the best way to

You've GOT to be kidding -- CW
Not if you're looking at an Eico 720. It will be difficult to identify keying
sidebands amongst the drift and chirp.

In SSB mode you can see the effect of the K3 Tx EQ and speech processor
as it relates to peak-to-average power.
And as you say it provides PWR and SWR
Now that I have the P3 TX Monitor I am wondering if this is anything more than
a mere light-show for entertainment. I am mostly CW and I find that the actual
TX display of the CW to be a bit silly looking and contrived. In fact, it
looks like something fake to me and I say that not as a

No need to purchase a W2 wattmeter now. Smile and enjoy; life is good.
