[ICOM] IC-775DSP

[Juan Pablo Mercé LU4DX]

Hi Paul, a pleasure of seeing it for here again.
Your ex-775DSP work fabulously!!, I add INRAD's roofing filter and SSB
narrow filters.
I make him a question because you know very well my IC-775DSP because it was
yours !!
Often and only in 15 meters when I apply power to my antenna that very low
ROE has, the rig shoots all the power in a few seconds and then it lowers
the power as if ROE existed to approximately 90 watts.
I connect the tuner, it fits 1:1 and begins to extract all the power again,
then I disconnect the tuner and the power returns to the normal one without
diminishing. I think that it is not a problem of ROE but of the form that
stays any bobbin in the tuner that as soon as everything gets accommodated
is corrected.
Do I spend this to him at some time?
