I recently got an ATU-100. ?It tunes but doesn't seem to retain the tune. On CW, for example, if there is a brief pause between words, it retunes. ?It seems to do this whether it is in autotune mode or not. ?This means that there is a brief spike in SWR on each transmission after a delay. ? Is this how it is supposed to work? ?I would have assumed it would hold its tune, at least until power was turned off.
Tnx
