Would everyone agree that an external speaker will provide more than enough volume in any situation? I picked up a Motorola external speaker at a hamfest (probably ripped out of a police car some place) and I get ear splitting volume from the K2 and even from the tiny Kenwood THF6a HT. I find that audio amps often provide plenty of power and it is just the speaker that isn't delivering to the ears. 73, Bob WB2DHK
