The mcHF kit has progressed a great deal over the versions. This kit being
the lastest version 0.5 has many SMD/SMT preinstalled by the board manufacturer. This saves a great deal of time
and labor placing very dense tiny components as well as lessoning the chances of poor installation.
I chose a bit of a personal preferences path in the assembly. The LCD was naturally too high for
my switches ( switch heigth = 13mm ) thus it got modified. The solution was to trim off a bit of the connectors
length and remove the plastic pins retainer. Adding the 4.4mm tall 2mm sockets so the LCD could be easily removed.
I wanted a E4 (tuning encoder) that is more rugged. I chose one with threaded mounting shaft. All my encoders
include the push switch. I could see no reason to have buttons M1 through M3 when those functions are easily done
with the encoder push switch. I also kept the push swich on E4 and elected to use it for an additional step+ .
After lowpass filters are all installed its time to finish SWR and PA sections. Turn it on
to test then mount my heatsink
Measureing, cutting and drilling the new Hammond case. Lots of screwups but it will do just fine.
The case is longer than the boards so I chose to add extension connectors on the right side. One could
optionally cut the extra length off the case.
