[K3] Modified K3 on 500/137kHz

[Petr, OK1RP/M0SIS]

Hi all,

as my K3 arrived back after heavy upgrade/mods and maintenance and I have installed all hw for VLF operation I am interesting in on-air experiences using K3 on 500/137kHz bands (rx or even tx)?

I am planning to use ANQ-1 preselector which I have been used for years with FT-990.

Thank You for comments and hints,
