ATU-10 realistic max watts?

really enjoy my atu-10, and it has been great operating /p with my qrp rigs...

here's my question: what is the realistic max rf output through the tuner? 30W SSB? 15W SSB? or is the listed 10W the max at constant carrier?

tia for any info!

Hi William,

I use ATU-10 with an mcHF; this transceiver also has 20W (and more) in 40m.

I noticed that at powers over 18 ... 20W the display shows "Overload" and the voltage on the ADC pin is over 4096mV. In order to be able to use the tuner with powers over 20W, I made the tandem at a ratio of 1: 6 and recompiled the firmware with the new value.?In this way the FWD voltage on the ADC pin does not exceed 4V, the maximum power applied (by tunning) would be somewhere around 30W, but it is at the limit supported (I think) by toroids.

Of course the deal will be made with a maximum of 15W as set by David.
