[Lowfer] 2200m problem found

[Dave ZL3FJ]

One of these would be an alternative

 It's a latching  DPDT relay used for openwire line switching. This one
needs a bit of TLC.
I used to have several but this one is the last and a 'keeper' for now.
 These might be found in the MF broadcasting industry if you have any
contacts there.

One alternative might be to locate the LF and MF loading coils (or the major
part of them) outside, after the vulnerable contactors, so that lower
voltages would prevail.  Might be physically awkward, but it'd be safer for
the house and could probably be configured so as not to affect HF
performance.
