range will be within the 17 meter band. However, this is not guaranteed. You should check the
VFO frequency with a counter connected the exposed lead of R­27, or use a well calibrated
receiver. Trimmer capacitors on the back of the main tuning capacitor will provide some
adjustment but you will need to select which capacitor sections are connected to set the
minimum & maximum tuning limits and the tuning range.
