My K2 PLL problems all originated in one inadequately tinned toroid wire. I have successfully built a fair number of kits with toroids, but it is pretty easy to end up with a lead that is not actually connected. Even though it looks good.
So that is where I would start, check for continuity on every single toroid.

Fitted crystals are 4.91s in X3 and X4 positions Have checked all the details in the trouble shooting paragraph, i can find no fault with any of the components, all values and positions are correct. I have to add that this was purchased as a non-runner. Any advice appreciated Snowy,G0HZE ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
