[Elecraft] My poor K3

[Robie Elms]

Ronnie,

Two thoughts:

1. What is your power supply output voltage with the K3 transmitting.  This
measurement should be made at the K3. It should be approximately 13 volts.

2. Try transmitting into a 50 ohm dummy load vs. your antenna.  Is there
any difference?

3. Repeat 1 with the K3 connected to the dummy load.

These measurements may help you identify if you have a problem with the K3,
your antenna or your power supply + cabling from the power supply to the K3.
