Hi Bernie,
I should have answered this sooner, but was out of town.
Here's how it works. The K2 doesn't have battery-backed-up RAM (which,
obviously, requires a battery, as well as other hardware/firmware
support). Instead, it has an EEPROM which stores all parameters. The
present band, mode, etc. is saved in EEPROM whenever you change bands.
But it is also saved after you've shown an "interest" in a particular
frequency -- by not moving the VFO for 30 seconds. This works almost as
well in practice as battery-backed-up RAM, but avoids the cost of a
battery, socket, and power-off/power-on switching and detection
circuitry.

I'm still leanring all the features and quirks of my K2 (5705) and
have a
quick question. Exactly how does the default frequency of each band
get
set.. The manual mentions how 'each band memory is preset..' on first
turn
on, but I can't find an explanation of how it is changed. By trial and
error, it seems to be changed when I change frequency, then change
mode, but
not just by changing frequency. So if I'm in cw mode, tune to an
interesting
frequency, turn the radio off then back on, it goes back to a
previously
determined frequency, not the most recent one. If I change frequency,
cycle
through cw-usb-lsb-cw, turn the radio off and back on, it then comes
up with
the most recent frequency. The same behavior seems to apply to
changing
bands. Is this the way it is supposed to work and is it possible to
have it
just remember the most recent frequency on each band without cycling
through
the modes?
