Keyboard Mods to access AM detector and change band:
Press the ENT key once or twice to place HT in VFO mode and in the 2m band
Depress the F key for 2 secs. (Note flashing F in lower right corner)
Release F key and press MHz key
HT will shift to 118.00 MHz and activate the am detector
Store any freqs from 118-138 into memory

Your back on 139-170MHz with FM detector
This is a very sophisticated HT and now a great bargin
