210x only.
(b) Extended frequency limits by adjustment of VFO trimmers.
VFO trimmers are reached by removing the transceiver top cover. Adjustment of a trimmer for lower or higher
frequency will move the entire band down or up, and will came the dial Male to read less accurately. Special
frequency ranges with accurate dial calibration are available from Atlas on special order.
