Same seen here, as well as bursts of much more power on initial key down - very
evident last weekend during CQ WW RTTY - good for >3 dB more than our legal
limit, which the drive from the rig was set for to begin with.

Apologies to VR2MY, VR2PX & VR2NL if those spurts - plus key clicks on CW - is
behind their absence from the bands lately.

See K2VCO's reply to my post about firmware fixes a little while back - not 
done here
yet... too busy reading about mojo, BPL & the like.

Otherwise, I suggest you contact <[email protected]> - good for quick & 
useful
responses to things which go nowhere here.
