[K3] [Elecraft] more Obsolete?

> the TMS is NRND - not obsolete (yet)

Correct.

Remember, the K3 has been in active development - and the focus of my 
efforts - since the summer of 2003.

We did a lot of research in choosing this particular DSP for the K3.  It 
was chosen for very good reasons.

This part is still in production.  TI's track record with their DSPs is 
that they remain in production for several years after they reach NRND 
status, and they give their customers at least a year's notice for any 
so-called "lifetime buy".  There has been no such notice, and the NRND 
status only occurred in the last several months.

Yes, the schematic has a typo.

The CODEC is a TLV320AIC23B.  TI claims it is "active." It is not NRND, 
it is not obsolete.  It is in full production and fully supported.

The Transmit DAC is a TI TLV320DAC23.  Same story.

There is absolutely nothing to worry about here.

Relax.

Get on the air.

Call CQ.  Even if there were lots of sunspots, there would be no signals 
if everyone just listens!

Enjoy your K3!
