[Elecraft] Looking for K2 PCB

I would like to do some experiments with the K2 VFO. If someone has a dead (or unbuilt) K2 VFO/PLL PCB, I would be interested in it. Trades and/or a small amount of cash would be available. This is strictly for personal interest - I have attempted to replicate K2 VFO performance using ugly construc

Re: [Elecraft] OT: Need Antenna Tuning Help

The basic bridge in the MFJ - and lots of other impedance analyzers - is insensitive to the sign of the reactive impedance. You can figure it out by making a "small" change in frequency and seeing whether the reactance increases or decreases. However, this takes additional software in the uP, incre
