[Elecraft] KX2 / WM1 Reporting Conflict

[James Bennett]

Wondering if anyone can help on this - I’ve got a KX2 and W1 Power Meter. The power out on the KX2 does not match what the W1 is reporting. I have the W1 connected to my MacBook Pro displaying the serial data being sent to it.

I just verified that the W1 voltage at the TP1 connector is exactly 4.5 volts, per the manual. I ran the KX2 Manual Transmit Gain Calibration. The KX2 is showing exactly 6.0 watts into a dummy load, going through the W1. The serial data reported by the W1 is 7.20 watts, consistently. Also, the KX2 firmware is the most recent.

So, who is wrong - KX2 or W1? And what can I do to resolve it?
