Re: [Elecraft] K3 Voltage on TX

In general, it would be ideal if there were zero voltage drop. This just won't be the case in the real world.The VFO-B voltage indication is reliable in terms of the voltage in receive vs. the voltage in transmit. I think it reasonable to accept < 0.5 volt drop or less between RX and TX

Re: [Elecraft] Soldering crimped connectors is not a good thing.

Is the connection intermittent at the contact point or at the crimp? If your crimps fail over time there's an issue with the crimp or there's extreme physical stress that's causing the crimp to fail. Part of my background is Military Avionics. Our connections are constantly subject to vibration,
