You read the price list incorrectly.  They are indicating that the DTD-1 is NLA.

Glad the small board does what you want.  It's been a while but I do remember 
there are several ways to filter a square wave out to more of a sine wave, but 
as long as the basic job of Id'ing is done that's what counts.

  If you look at the price list is says "discontinued".  Had I seen the Tessco 
unit I might have gone that way.  The $20 dollar ID board will meet FCC 
requirements and the ID will not be heard at the other end of the link so 
everyone is happy.

      I could not find an ID-8 to purchase.   ComSpec did not list the item.  I 
could have missed it.

        Consider the ComSpec ID-8 for true sine wave output. Bit more pricy 
though
