[Elecraft] SDR and regs

[David Yarnes]

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.

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
