Sorry about the  garbage  text.   Second time this has happened this 
week, both times after doing a reply to a message.   Never happened 
before setting up this new Verizon account on  Thunderbird.


Ed,

My Tokyo Hi Power solid state amp  would often go into protection with 
the 590 before the ALC mod was done.   It was more of a problem on 
SSB.   The work
around on CW was to keep carrier level  in the low 20's instead of the 
default 50.   The work around on SSB was to run some minimal amount of 
processing.

Even with the work arounds, it would still trip the protection, and 
usually at the worst time.

Had the ALC mod done  in June of last year and  the few protection 
faults I've seen  since then have been pilot error.

The improvement  was very noticeable.  Again, the spike was less of a 
problem   on cw with the carrier  set lower.    Carrier set to the 
lowest setting
that would still give full output power.
