Charles and all,
Perhaps you are right, but I'm not sure you are right. For
one thing, most rigs of recent manufacture can be "opened
up", either by software or by snipping a diode or two. The
latter type is even easier to defeat than one controlled by
software, at least for most, since you have to be somewhat
technically astute about software to use that method.
Snipping a diode isn't necessarily that difficult.
Restrictive control for either type is pretty easy to
overcome.
But the real reason I suspect it won't be a problem is that
apparently software controllable radios have already been
approved just about everywhere I think. For example, the
FT-1000MP Mark V can be opened up just by accessing the
right menu. I guess that isn't exactly "software" control,
but it's similar. You are using the rig's internal software
to make the change as opposed to using a computer connection
externally.
Just my guess.

Subject: [Elecraft] SDR and regs
SDR radios may come to be a problem for hams who
live where there are tight gov regs on freqs rigs can
cover because the argument is, if they can be programmed to
lock out some bands, they can be brought back by software
easily. Since virtually all radios in the future will be at
least
part SDR, woe is some. 73

Subject: [Elecraft] ARRL: K3 is SDR
There was an earlier discussion on the list about the
definition of
"Software-Defined Radio" and whether the K3 qualifies. The
answer
appears in W1ZR's "Getting on the air" column in the
latest issue
(September) of QST.
The answer is that "SDR" does not necessarily imply
open-source
software. Proprietary software qualifies, as long as it
can re-define
the receive/transmit RF paths and be downloaded in the
field. They
specifically mention the K3 (and IC-7800, TS-2000, Orion
and FT-2000)
and even include a photo.
So the oracle has spoken. Question resolved. :=)
