We're just making sure performance is as good as possible. (The stakes  
are even higher in a QRO tuner.)

The most recent prototype worked great, in general, but on 6 meters we  
felt the  loss was a fraction of a dB too high. The PCB layout has  
been changed to cut the RF path length and strays by a factor of two,  
which should do the trick. We'll receive these boards in a week or so  
and should have test results a week after that. This suggests that we  
could have some field test units out in mid/late-March.
