Not much soldering going on these days, however the noodling
process is ongoing. This time I’m going
to take my own advice and think out the entire project before etching boards
and soldering components. Might prove
interesting. I suspect that this process
will prove to have a better end result but take much longer to get there.
The case for the LBS2 transceiver arrived the other day so I
can now actually see how things can or cannot fit as envisioned. I’ll mock up all the boards in cardboard and
confirm the fit in the case.
Pretty much if not all the circuits are already done in
Kicad and therefore only a re-work of the circuit board layouts will be
required. I was going to combine some
boards but have decided against that in order to allow for full flexibility of
modifications. One change for sure will
be space for an additional board for future expansion and another slot for
another amplifier board to boost the power up to about 20-25watts or so.
The mother board will only have DCV traces etched and all rf
and audio signals will be in coaxial cables.
AND I will be sure to leave one end of the shields open so as not to
create ground loops. A lesson well
learned with LBS1.
All the boards except the control board, consisting of the
dds, lcd and the Arduino, will be mounted via sockets on the motherboard. I’m having a little trouble with the Nokia
display so it may be time to plan for the colour touch screen modification.
Here’s a picture of the case. For $10 CAD I’m ok with it
been plastic and not metal. In fact for
10 bucks I should have ordered a couple.
Figure out a project for the case later. Hihi.
73, Peter
