This RTTY system configuration is the worst one I can think of (sorry!).
The RTTY receive will be great for you and transmit will be greatly
compromised, for both you and your QSO partners. Once you have a PC/modem
interfaced to the K3S for receive it is trivial to use it for transmit as
well. Th
Rick and All,
The Sherwood performance chart is strictly about RX, not TX!!! If you want
TX info, you need to go elsewhere. That's what reviews like the ones in QST
can give you.

I have a helper at my computer. He is a little corduroy pig called Pablo. He
has been with me since my Hewlett-Packard days in the 1980's. He squeaks

working I go to Pablo, pick him up, squeeze him for a few squeaks, perhap
I can tell you that being on the other side of that kind of QSO can be
painful, even with something as simple as a contest exchange. From that
point of view, the paddle is acceptable only if you can send about as
fast as RTTY. Not a lot of hams can. :)

I'm hoping hat I can use the K3S sound card hardware & PC software for
the receive side, and use the paddle CW interface as the transmit side.
Any experience in the group with doing that?

Obvious questions
Do the birdies (mostly) go away when the antenna is disconnected? Could
they be coming from in-house sources?
Are they there when the receiver is operated (on a battery) away from
potential sources?

The K3S built in soundcard will relieve you from the cabling problems

single channel external soundcard).
It will not relieve you of the "level tweaking" because the K3S CODEC is

Your inference is right on. You CAN run any digital software that

Do you not like the KX2 compressor ?, don't use it ?, so much so that you
take the TT-715 along portable or at home strictly ?.
Interested in your observations. If there is such a huge difference in
compressors I think certain gents that monitor this list might see that as a
challenge.

Ed's message is another confirmation on why it would be really great if
Elecraft would modify the K3 software so the MENU would allow us to select
separate AGC settings for: CW, SSB, and RTTY.
I realize this may be a first, but Elecraft is good at leading the pack!

The KX2 was pretty thoroughly reviewed by Peter Hart in the January 2017
edition of RadCom.
Without trying to reproduce the receiver data tables, some representative
numbers are:
3.5 MHz close in IMD (500 Hz bandwidth, 2 kHz spacing with preamp off) yielded
a 3rd order intercept of +15 dBm and
I have ONLY operated QRP and 10 watts with my KX3 and that is all I plan to do
with my KX2.
Operating QRP with a compromise antenna is a challenge and it is fun. I am
surprised that more
people do not love this.
Of course CW only!

I think the Sherwood ranking to KX2 means nothing unless you have a KW amp
(e.g., Expert 1.3k after mods) and run it in a contest or DXpeditions. After
all, nobody will hear you. Also nobody will hear your IMD3 except your next
door neighbor.
The biggest values of a QRP radio are:

You're correct. But in fairness, those items should be based on a
standard output power (not everyone wants QRP) and we already know that
you're the only company concerned about those points and you're the

As I had said, it's more than numbers. There are many other factors
Too bad Rob's table doesn't have columns for size, weight, or current drain. I
think the KX2 might have the lowest numbers in all three categories.

I can't comment on the quality of the K3S USB interface, because I don't
own one. The decoder built into the K3 is pretty good, often as good or
better than the software decoder. When used with a keyboard and P3/SVGA
