I occidentally removed a pin from Z1 and soldered it back on its little internal board. It looks OK, but when I try the VFO test, the K2 says 7100.00, goes to 7100.01, and then back to 7100.00. When I spin backwards, it goes to 7099.99, then back to 7100.00. I take this to mean that the 5V supply is OK (since it does something), the quadrature outputs are OK (since it knows direction) but the clock is bad. The clock is the pin I pulled off.
I traced the circuit on the internal board and the pin appears to be connected, but my theory is that it somehow suffered some other damage. Ordering a new one seems like a fairly expensive proposition, so I'd like to ask if anyone has ideas about testing it out of circuit (just apply 5V and look at the outputs on a scope?) or other possibilities for problems that might coincidentally cause these symptoms. Alternatively, does anybody who did the http://www.wm5r.org/k2-100/encoders.shtml switch to a different encoder have one that they don't want and would sell for less than a new one? _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
