Here's a cute little $9.99 (shipped from Hong Kong) audio amp that I use with my K3's: http://cgi.ebay.com/Mini-Hi-Fi-Stereo-Audio-Amplifier-Car-Motorcycle-/290506078266?pt=LH_DefaultDomain_0&hash=item43a382f83a
If you have trouble with that URL, it's ebay item number 290506078266. I bought the unit from that seller, but it is available from others. The audio out is pretty clean if you turn down the bass & treble controls. I connect one K3 line output to the left channel, and the other K3 to the right channel. I've only had it for only a few days now, and haven't run high power on any band other than 160, but it is immune to RF on that band at least. 160 is usually a troublesome band for RFI. The case is aluminum. On the K3's set line out = phones. With this external amp, and protective Schottky diodes across the output, I'm hoping to expand the K3's overall usable dynamic range with agc off. I'll give it a workout in the 160 Stew Perry contest tonight. The rainbow flashing lights behind the volume control are goofy, but you get used to it. There is another audio amp on ebay that wasn't there a few weeks ago: http://cgi.ebay.com/AV608-Audio-Stereo-Amplifier-Amp-Mp3-Mp4-Ipod-Car-/260708878380?pt=Car_Amplifiers&hash=item3cb375c82c It claims to have higher power out, and comes with a DC cable. I probably would have bought that one if it had been available. I have not tested it, but it looks interesting.

I can't speak for others, but my K2 behaves the same, Ian. More audio output would be nice.
