SPE Expert 1.3K-FA. 2 full radio inputs with RS232, ALC and keying plus SO2R
input, 4 antennas and will run 800 watts on RTTY with no temperature
problems.
That was my choice after trying Quadra and Acom.
The biggest difference here was the ability to instantly band change without
that tuning up on my old 4CX1000 amp.

Subject: [RTTY] AL-80B Or KPA500 for RTTY Contesting
I continue to upgrade my hamateur radio station for the upcoming winter RTTY
contest season. Recently I sold my Icom IC-756 Pro 3 which had served me
well for allot of years and purchased a new Icom IC-7600. I also have a new
Icom IC-7410 that will also be put to use as part of a SO2R set up.
I am now contemplating a new linear amplifier. I have been running the
Ameritron AL-811H for quite a few years. I'm contemplating either a new
Ameritron AL-80B or an Elecraft KPA500 for reliable output on high duty RTTY
contesting. I usually use 400 watts max for RTTY contests and it's always
been a very effective.
Any comments on the two amplifiers especially their duty cycle stoutness
would be much appreciated.
