SB-401 Question

[Mark Graalman WB8JKR]

  Ed, according to my manual if the 401 is used with the
303 RX the trap is removed. I've run all the numbers on
this and see absolutely no reason why the trap was ever
needed to begin with. The only thing it could possibly do
is guard against the 4th harmonic of the LMO which seems
ridiculous to me
