[Jan Erik Holm]

This was on the agenda a while ago. Any
progress on it?

Hi Jim,

I looked into this. A small percentage of K3s would be able to tune
below 500 kHz as-is (to 400 or 450 kHz), but most would require a
synthesizer board modification. The original design was not intended to
go below this level.

Might be a good idea for down the road to include 2200 meters
(135.7-137.8kc), 1750 meters (160-190kc) & 600 meters (495-515kc) as
some countries already have those bands as Amateur bands. There are
groups in the US working to get all three bands as Amateur Bands. The
ARRL is one of them.

Frequency stability is extremely important for operating on those LF &
MF bands.

Can´t see why it´s more important on LF then on HF/VHF/UHF
however frequency stability is always good.

For very slow data modes.  A pal used 100W to a low antenna (probably a few mW erp) and several minutes per character, in a few Hz channel, worked a guy several hundred miles away.  He is looking to temperature control the crystals in his rig and pc.
