[Elecraft] KXB30: Devil's in the Details

[John_K7FD]

I'm happy to report KX1 #959 is now sporting options KXB30 and KXAT1...and
all is working as one seamless unit!

I must admit that the dinky KXB30 is a deceiving little board! By the time
you route the wires down through the main KX1, you've earned your stripes on
this puppy. The detail work required isn't difficult but if you've got all
thumbs, good luck!

One note; the rubber pads for the 30 meter module had me scratching my head.
My soldered leads were pretty darn 'flush' but certainly not flat or smooth
enough to have those pads adhere worth a hoot. I ended up cutting the rubber
pads into slimmer strips that were then strategically placed in between
solder points so as to get a nice flat bond to the pcb and still offer
rubber bumper protection. 

Second note: the manual states that one of the 30 meter alignment trimmers
may be 'broad'; in my case, broad meant finding 'no' peak on the one nearest
the bandwidth pot. I used my K2 as a reference signal and could not
determine any peak what so ever. Tomorrow when I can hear WWV, I'll try to
peak it again. The other 30m trimmer peaked nicely.

As far as the KXAT1, the optional power calibration will be performed
tomorrow as well. Can't believe the P6.3 it's saying for output...this is
with pots R1 and R2 set to 60% as per errata sheet...

All in all, a delightful trip down kit building lane...with a few detours
along the way!
