The record player case is now modified for the radio and the
main PCB is fitted. I have also made the power and antenna connections. I
recommend using miniature coax for the antenna connections unless the connection
is very short. I used a surplus length of RG316, but RG174 would also be fine. The
radio will have the option of being powered by ten AA size high capacity NiMH cells.
I ruled out using a sealed lead acid battery due to weight and environmental
concerns. I considered using a lithium ion battery but also ruled it out due to
cost and potential safety issues.
I have been cutting the front panel for the controls,
sockets, display and ventilation. For marking out I always cover the metal
panel with masking tape and mark it with a pen or pencil. The masking tape also
protects the panel from damage if the panel does not already have a plastic
film across it.
To be continued.
