Re: SWR High SSB ONLY - When Using LA-1K Amp


 

My IC-7300 kept overdriving the LA-1K even with relatively low drive (30 watts), no matter what I did. Later, I heard the 7300's are prone to run hot and my 7300 seemed to be one certainly did. But, after I put my Yaesu?FTDX10 in line, the overdrive warnings went away. No problems since. Maybe it's an ICOM issue??

I have two LA-1K amps and two HF-AUTO tuners.
One pair is connected to my Flex6400 and the other pair is connected to my IC-7610
The pair connected to my Flex6400, I have no problems, full 1200 watts out on SSB, CW and RTTY
The pair connected to my IC-7610, the LA-1K keeps tripping out on SSB only if I run it over 500 watts. On CW and RTTY, solid 1200 watts.
I tested both set ups on all antennas, Dipole, Yagi, Vertical. No difference.
