Hello Dave,


> I have a K1 that I’m looking to sell, and took a look at the power output before listing it.  Power output is as follows:
> 
> 40 meters 5.2 watts
> 30 meters 4.5 watts
> 20 meters	1.3 watts
> 17 meters 0.7 watts
> 
> These are obviously not the expected power output levels.  Power supply voltage = 12.8 volts.  Output set to 7 in the menu.
> 
> What type of fault would this indicate?

All components for the filters for 40 meters and 30 meters filters are located between 
same contacts sides of K5A/K5B and K6A/K6B. The components for 20 meters and 17 meters are 
located all on the other sides of these relais contacts.

I therefore advise you to check the contacts of these relays as a first step. If you have 
switched the K1 to 40 meters or 30 meters, zero ohms should be measurable with an ohmmeter 
across the contact.
