I just completed my first PSK31 QSO with the K2/100 at about 30 watts. The heat sink got very hot so I took the power down to 20 watts. The KPA100 option is rated at 40 watts with PSK31 and 25 watts with modes like MFSK16. The power was read with a meter that had a peak reading setting. The average power was even less. That is because PSK31 doesn't have a full 100% duty cycle.
The heat sink did get very warm. I know I can put a computer muffin fan on the heat sink. I saw something on the N0SS web site about this. I don't know how hot is too hot. The right side panel on the K2 also got very warm. I don't want to ruin the KPA100 option, but I did stay well with the recommeded limits. 73, Steve N6VL K2 #2289 _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
