Default Re: Loading capacitor Yaesu FT401

Antenna relay has been swapped out for a pair of "man" sized Omron relays, original relay only used to switch the bias and switch the Omron's, They make a very satisfying "CLUNK" on change over. 60mA PA bias and no shortage of PA current available, it seems to be a case of coaxing the RF out of the tank circuit thru the matching network.
