[Elecraft] INFO 080 when building K2 #1348

Sun Oct 12 12:55:08 2003

Gret et all

As I get something that seems resonably right from the output (pin28) I�m
under
teh impression that the IOC should be all right.

When trying the 4Mhz resonator for signal it looks like it only gives a very
small
one. (I�m afraid though that it might be stray from the MCU-osc).

How can i measure the ICU-resonator ??
