If you are using a Softrock as a panadapter with your K2 you might be interested in this:
The usual Softrock setup used with the K2 is slightly different than the standard Softrock setup because it samples in 3rd harmonic mode because a correct xtal freq is not easily available. This mode is a little less sensitive.
I found a cheaply available xtal that has a good freq for normal x4 sampling: 19.8 Mhz, giving a Softrock LO of 4950 KHz. It is part 300-8213-1-ND at Digikey. It is a SMD crystal, so you do have to be a little creative in mounting it on the Softrock board. You also need to change some discrete components in the oscillator section beause it is a higher oscillator freq. But it seems to work well.
