HNY all,
A receive-splitter is a thing that is easily built guys.
Look on W8JI's site and search for combiner or splitter.
I constructed a few magic T splitters myself and they work just fine.

Hah! Our mailbox is on a well-traveled road about 200 yards from the
house and not in line of sight. When we first moved here, I had one or
two packages just left on top of the mailbox, and I complained
vigorously to the post office. Since then, our carrier has delivered
any packages too
Thanks guys. Looks like the W8JI design is easiest to build.
Mouser has the binocular cores needed.

Yes! My mailbox is a half mile from my house. When I checked with the Post
Office I was told rural route carriers are only paid to deliver to the mail
box. If they bring packages too large for the mail box, to my house, they
are doing it on their own. Fortunately, most carriers will bring large
The 40 dB Power Tap detailed in June 2001 QST article called Simple RF

I would note that if you intend to use combiners with signal generators
for intermodulation measurements care has to be taken with core
selection if high performance amplifiers are to be evaluated.

Hi folks,
Newbie Dave, K6WDE, here with my KX3 WOW moment.

I don't know if you got an answer or not, but I just verified that on
RTTY, there is an occasional delay between the SLUSB keying and the
radio keying. It's not there all the time and I did not get it to delay
on PSK31 (I only tested RTTY and PSK31). I have a couple of CR's built
I'd like to see PSK-D be supported by the FSK keying line ala RTTY via
FSK-D.

It's a totally different protocol/code ... RTTY/FSK is an on/off keying
signal while PSK31 is a variable length code that no UART is programmed
to generate.
If you don't want to use a sound card for PSK31, use the terminal in
the K3 Utility program.

While reading the manual to setup PSK using Data-A I now read that PSK-D is
actually capable of being driven by FSK keying line already! Missed that
one.

For the first time since drinking the Kool-Aid years ago, I made it all the way
through SKN without touching an Elecraft radio! Nothing but my HW-16 and
Heathkit CW twins was used, though I did have to use the AF1 to help the old

Nothing makes you appreciate your K3, KX3, K2, K1,
I'm interested in learning how you explain to your software that it should
listen for PSK and decode it while it's transmitting FSK.

I haven't tried it yet since I just discovered it. The FSK pin on the AUX
connector when in PSK-D mode does what is needed. It's the mode on the
radio that determines whether the FSK pin does one thing or the other.
Make sense?

Guys,
John Subich was right. Asserting PTT keys the radio and brings up the PSK
idle, but there is no data transfer via the FSK input pin in PSK- D mode. The
Vari-code aspect of the various PSK modes makes this impossible as it's
currently implemented.

Must be an erratum in the User manual:
From Page 31 of version D10 K3 Users manual:
PSK D is a Direct-transmit mode for PSK31. It’s the only mode that decodes
and displays PSK31 signals with the text decoder (pg. 33). Like FSK D, *PSK
D lets you transmit via FSK IN*, ASCII, or the keyer paddle
The issue isn't varicode.
The issue is that PSK modes are Phase Shift, not Frequency Shift (FSK).
The radio would have to read raw data coming in, re-encode it, and
modulate it.
It isn't that different from CW-to-PSK conversion, but I wonder if it's
worth the trouble.

That *is* an error. PSK D allows transmitting via ASCII (using the KY
command) or keyer paddle. It does not accept any input from the FSK
line.
