[Elecraft] K3 Suddenly died

[Gary Gregory]

Actually, both outputs are correct. When first released the K3 did go to
120w but was later reduced to 110 by a FW revision which is maintained in
all FW versions from that date if my memory serves me correctly.

In the interest of keeping IMD to a minimum, best practice is to set the k3
output to sub-100w.

The amount of signal loss when using a setting of say 95w is arguably not
to be noticed other than with test equipment.

My AUD 2 cents worth..I get short changed on the exchange rate anyway...:-)
