Remote control. Very useful in some situations. Especially if you aren't
allowed to have decent antennas where you live.
The kick I get from battery-operated QRP operation is communicating without
infrastructure. I am out there with a battery, a radio, a NUE-PSK modem and a
portable antenna. No internet, no power company.
(Full disclosure -- I don't yet have a portable solar facility to recharge my
battery, so right now I'm still tied to power company infrastructure for
re-charging. But architecturally, I don't have to be.)
As you say, both approaches have value. This diversity is why Ham Radio is so
interesting....

NUE PSK is great for back packing and mobile operation so long as only PSK 31
or RTTY is of interest. Computers offer a richer display with more options and
the ability to generate many different modes. The idea is to go directly from
the computer via IP to a back box that is broadband and can be remotely
located and is mode agnostic. Both approaches have their own advantages.

Will be interesting to compare this effort to the NUE-PSK, which takes a
different appoach. They have a modem that plugs directly into a transceiver' s
Data port eliminating the need for PCs and soundcards, but they are now working
on a "NUE-SDR" transceiver that either will fit as a card inside the little
modem, or attach underneath it (not sure what their final design will be).
This would eliminate both the PC and a separate transceiver.

"I am developing a 'modem' to directly modulate computer generated modes to
RF thus eliminating the requirement of using a transceiver audio input"
Welcome to the group, tell us more.
