[Elecraft] I need some guidance - KAT500

[Andy Durbin]

One thing that you may not understand is that MAN with BYP active is the same electrically as BYP mode).

I use all 3 ANT ports of my KAT500 and never used any KAT mode except MAN. Some of my antennas work fine in MAN/Byp and others require some help with L and/or C.  All antenna switching is automatic with a seamless re-configuration as required for any band swap.

Each memorized tuning solution (6 possible per frequency bin) includes the Bypass relay configuration (BYPB or BYPN).

e.g.:

dm;
DM BN06;BIN 54;FR 18080-18099;ADDR 42040;
AN1;BYPB;VSWRB 1.00;
AN1;BYPN;SIDEA;C03;L04;VSWRB 1.23;
AN1;BYPN;SIDEA;C04;L04;VSWRB 1.29;
AN1;BYPN;SIDEA;C10;L08;VSWRB 5.15;
AN3;BYPB;VSWRB 1.00;
AN3;BYPN;SIDET;C00;L21;VSWRB 1.00;
