[Elecraft] KX3 And Alexloop?

[Frank Krozel]

Fred,
Pretty interesting calculator - I have not seen that before.
It is interesting how much better an antenna I can have on 40 meters if I go from 9’ to 12’.
Hmmm.
Anyone tried a slightly larger loop for an Alexloop?

KAT2 has to be bypassed because the loop *must* be exactly resonant, but I really like the loop.  It's on the edge of too small on 40 and the tuning is quite touchy, but 10 MHz and up it's a snap.
