[Elecraft] Want to swap K3 8-pole filters: have 1.8kHz, want 400hz

[Thomas Horsten]

Hi

I have an 1.8kHz filter that I'd like to swap for a 400hz one so I can
match the subreceiver for diversity CW RX. I don't really need the
1.8kHz filter as I'm not an SSB contester.

If you have one and would like to swap, please email me off-list!

Thanks and 73,
Thomas 2E0ETT
