Stewart,
Do you have the latest firmware loaded? As I recall, there were some
changes to the power controls in the latest release which address that
very problem. If you have the latest, then try the next release.

Whilst transmitting today on CW (QSK) at full power, I've noticed on a
couple of occasions the power meter showing a fairly sudden drop in
power to around 45 or so watts. It gradually returns to full power and
then will behave normally for long periods. Each time this has
happened the radio has been on 80m and the ATU has been in circuit;
the power setting remains at 100 watts the whole time and the current
meter on the power supply does suggest that the power is indeed
falling. The SWR indication remains low and the PA temp stays around
37 deg.
If it continues to happen I will make more careful observations but as
an initial step thought I'd see if anyone has experienced this or has
any idea of what may be going on.
