1. [Amps] AL-80A "spitting" on 80m, Relay problems. (score: 1): Author: Bill Coleman <aa4lr@arrl.net>; Date: Sun, 11 Sep 2005 20:54:36 -0400; I used my AL-80A during the recent NA Sprint. I found that when I went to 80m, it was difficult to tune to more than 300 watts without exceeding 150 ma of grid current. After a few minutes, I also he; /archives//html/Amps/2005-09/msg00095.html (7,144 bytes)

Mr. Measures suggested reversing the coil wires -- I'm not sure what good that would do, unless the relay frame has become permanently magnetized....

The cure is blazingly fast (<2mS) relays closure. More C = less loading. Less C = more loading. Richard L.

After carefully tuning up the amp for 80m, using as little loading C as possible to get the maximum output, there was no spitting into the dummy load.
