Anyone know why they only solder one side, thinking about soldering it but not sure if there is a good reason they didnít. New old guy, Kg6jxs, my lisc expired years ago and Iím having trouble getting a new test because of coronavirus. Just gearing up.. FA technician by profession. Iím thinking board flex issues or some sort of tuning? Or lazy/cheap? Thx in socal these days.
