Hello Phil,
My K2's serial number is in the 5000s so it has the temperature
stability circuit built in. I have only just recently started using it
on JT9 after some time on JT65. I don't start transmitting until it has
warmed up after 5 minutes or so. I first used it outdoors at my remote
site (see VK3TUN on qrz.com) and had to shield it from the wind. Now
that the shed is up, that is no longer an issue. I don't know if it
helps that much with dissipating the heat, but I always have the bail
extended.

David,
Do you do anything special to ensure frequency stability in those
modes with your K2?

I've made hundreds of contacts using JT65 and JT9 with my K2 at 5W.
Most of these portable on a 12v battery with solar charging. With a
48 second transmit period, it's probably more of a stress test than
BPSK31.

What is the safe level to operate the K2 at for the PBSK31 mode? I'm
thinking 2 or 3 watts. tnx 73 Bruce ve5rc
