ICOM IC-28A AND IC-28H \par \par To make the IC-28 transmit 138-174 MHz, cut D21

(no retuning required). D21 is a tiny glass diode standing on-end near the centerof the upper circuit board,

accessible by removing the top cover.

The IC-28 is the only convertible ham rig I know that covers the 170-MHz federal government

(including national park) frequencies.
