Summary: #+B unlocks receive on all 3 models of Icom x21AT series
X-Newsreader: WinVN 0.93.14

This might be old ground I'm covering, but someone asked about it here a 
couple of weeks ago.

The Icom W21AT dualband HT can be given an extended receive range (50-999 
MHz) by doing the following: turn radio off; hold down # and B keys, then 
turn radio on; wait for the display to cycle through a self test and for the 
radio to beep, then release the buttons.

The instructions mentioned that there should now be a new RP function in the 
SET lineup, which allows the W21AT to access these frequencies. I do not 
have a W21AT to verify this.

But I did verify it with a V21AT and an X21AT. It works on both, to varying 
extent. The V21AT unlocks the 220 side for 215-230 MHz receive; no change to 
the 2M side (it still covers 136-174 MHz normally though).

The X21AT unlocks very nicely, allowing you to tune 50-1310 MHz, continuous 
coverage! The 2M portion covers 50-300, the 440 portion covers 300-1000, and 
the 1.2 portion covers 1000-1310 MHz.

To access these frequencies, at least how it's done on the V21AT and X21AT, 
use the [f] DSEL function to select MHz/KHz etc. There is no extra "RP" 
function in set, at least not on these models.

Thought this would be of interest.
