Tom, the #12 cable should be just fine for the K2/100, BUT the battery may be suspect - yes that battery size should be just fine but if you are running at higher power, that battery should allow you operation for about 2 hours if it is in top condition. The condition of the battery may have a lot to do with the situation - many batteries develop a high internal resistance as they age. Connect that K2 to a good deep cycle (or well charged automotive) battery as a test and you will likely find better results.
Tap the display button and look at the voltage on the K2 display while transmitting with that 52 Ah battery and you may be surprised how low the voltage will go. The K2 receiver will operate down to about 9 volts, but transmit will have its limits. Normally you should not let the battery voltage drop below 11 volts. Another thing to check is the APP connectors - if they were crimped, did you use a good crimper? The non-rachetted crimpers are usually just not adequate to assure a good connection - try soldering the connectors to get a good low resistance, high current worthy connection (fill the connector with solder but don't get any on the outside). 73, Don W3FPR > -----Original Message----- What cable size should I use?
