I've been doing a lot of FT-8 using my KX3 and my KXPA100 at 20 watts, and have noticed that the KX3 is heating up quite a bit and is almost hot to the touch. The KXPA100, while warm, appears to be okay. Should I consider purchasing a heat sink for the the KX3? If so, what products in your opinion are the best? Thanks,JimW7JHR Sent from Yahoo Mail.
