Getting ready to use my K2 SN6473 on PSK and possibly other data
modes. Wondering if there's any issues w/IMD on the K2? I seem to
remember seeing somewhere on the web a mod made to the SSB board? or
was that just early SN K2s? Or if I just watch my gain/power levels to
avoid any ALC
Steve,
That is old information that you were seeing. Those changes have been
incorporated on your KSB2 - of course, if you purchased an older KSB2
board from another owner, you should check it physically against the
values changed by that IMD mod. The mod instructions are on the

Folks,
A bit OT, but worth mention on this list.
Kristen K6WX wrote an iPAD app for PSK-31 and made contact with a
station in TX over the weekend to prove out her app via a K2.
Check out the uTuBE video made at the SLAC National Accelerator Lab in
Menlo Park last weekend.
Just built a KPA100 for my K2 S/N 6274. When originally running PSK on the
barefoot K2 had no problem achieving IMD around -30 dB (measured with
PSKmeter). The K2 had a KAT2 tuner which was removed, and replaced by an
external autotuner when the KPA100 was installed.
With the new KPA100 in

The KPA100 can be coupling back into the KSB2 option.
Remove the right side panel and tuck the ribbon cable and speaker cable
up into the space at the top of the KPA100 instead of letting it dangle
near the KSB2 board.
I will not guarantee that it will help, but it often makes a

None whatsoever. The fewer

PSK is an enjoyable change of pace, and an effective
mode for low power/modest antenna operation. It is a
great conversational mode (and to boot one can listen
to music while having QSO's!).
Since processing is done in the PC, you generally want
to give the PC the full audio passband -

The digital software does it's own signal processing. I don't have the KDSP2
in my K2.
You can define a set of crystal filters for digital modes. I defined mine
around 1500 Hz. Software like

Anyone have any success hooking up the K2 to the soundcard for PSK.

Jack,
Yes...
Take a look at the 'Switchbox for digital modes' article on my website
www.qsl.net/w3fpr for some ideas that may be applicable to your situation.
You should be able to expand on that to suit your individual needs.
