Just noticed that the instructions in the K2 rev D manual, page 60, say to do CAL PLL anywhere between 7000-7100 kHz. But the troubleshooting section, page 8 of the appendix, say it should be done on an even multiple of 100 kHz, plus a small amount -- like 7100.10. I am presuming the main section of the manual is correct, with the new firmware... Andy
