KL-203 Mobile *

I have been using the KM 203 now for about 3 years either with my Uniden 980 or my old Uniden Grant. This little amps lets me make those contacts on sideband that would be difficult to make barefoot. I have abused this little amp and it still is kicking. I have even got my name called on Channel 6 using this little amp. I have been told that my radio sounds clean using this amp, no distortion just a better signal. For $70 buck it is well worth the price. It does get fairly hot with my 980,but that is on me. I need to turn the 980 down about a watt a half. With my old Uniden it gets warm. 1.5 to 2 deadkey watts would be best to drive this little amp.

I want to start off by saying that this amp doesn't need much drive and driving it with more power than 3-4 watts will do nothing more than splattering your signal. I have two 203 (none P) amps with hundreds of hours of use and NEVER blew one up. I hear people complaining that this amp is crap and that their amp quit working just after installing it, can you guess why? Yep, they used their peaked radio or didn't check their SWR but they still blame the amp? One of the amps is used with my RCI 2950DX and I drive it with 2 watts in and get 90 watts AM out, and with 12 watts in I get a full 200 watts out on SSB with a very clean signal on the 10, 11, and 12 meter bands. If you want to connect your peaked radio to this amp, you too will be calling this amp junk just like one of the other reviews I just read but, if you drive this amp as it was intended you will get years of service out of it.

This is a great buy,can mount anywhere, clear out put and great price !! Thank you Copper
