If that is a KL203p, you may want to add a fan to it and also lower the DK on AM to 2w or less and use an external swr/watt meter as the internal one gets funny below 2 watts of dead key on AM. Also on SSB you can turn the power back a bit to about 8-10w pep. This will help ensure that your equipment lasts a lot longer. Don't worry about losing a few watts on the meter as no one on the other end can tell the difference between 70 or 90 watts!! JMHO. You will also find that the radio won't get hot either by cutting back on the SSB output power. JMHO. Keep it clean and mean!!
