One reason to buy an Elecraft K3

In the past I've bought radios and discovered that they were slightly deaf or off frequency. I found it frustrating that I didn't have the test equipment or the knowledge to align the radio and obtain the specified performance of when the radio was new. I'm not talking about a misused radio, just what happens to all radios through age due to high temperatures slowly changing the tolerances of components.

With the Elecraft K3 I can align the frequency readout at any time with an accurate source like RWM (9.996 or 14.996 MHz). This means that the radio will always be exactly on frequency independant of age. I can do this with no test equipment and in no time at all.

One of the causes of a radio going deaf is the IF wandering outwith the centre of the IF filter passband. With the Elecraft I can use it's internal test resources to measure the response of any roofing filter and I can work out if signals are still central to the filter passband and adjust the IF accordingly.

This means I should be able to maintain my radios performance to a higher degree for as long as I choose to hold on to the radio, without the need for specialist knowledge or elaborate/expensive test equipment.
