[Elecraft] K2+Softrock xtal

[rt_clay at bellsouth.net]

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.
