Hello everyone,

I'm considering the purchase of a K2 and would appreciate any information and/or
opinions that you might have.  I'm strictly a QRP guy so I'm not interested in
the 100-watt version.  I would probably want the internal tuner.  I don't work
SSB, but PSK is of some interest to me so I'm thinking about the KSB2 option.
Other than that, since money is definitely an important consideration, I would
be very interested in opinions about the KIO2 RS232 interface - would it help
with PSK?  I would also like opinions on the KAF2 filter vs. the KDSP2 DSP
filter.  My current rig is a K1 so just about anything would be "gravy" to me -
I'm not comparing the K2 to some Rolls Royce kind of rig.

Thanks in advance for any help that you can offer.

I found the KIO2 useful for PSK as I'm a great believer in using narrow filters to get the best reception of weak signals and the software I used allowed me to center a signal in the passband and select narrow filters using a click of the mouse. Since I used MixW logging software I had these features available in CW too.

I never felt the need for the KDSP2 and only had the KAF2 which was all that was available when I built my K2 in any case. To be honest I never used it that much and found the 4 choices of filter bandwidths the K2 offers per mode to be more than adequate.
