Re: High power XPR4550 maxed out at ~20 watts

Yes -- I took measurements on analog frequencies with the mic PTT as well as via the KEY TRANSMITTER button in TUNER. I believe TUNER uses analog transmission for softpot adjustments.

Re: High power XPR4550 maxed out at ~20 watts

Thanks for your tip. Low was set to 20.00 and high set to 28.50, so I set high to 48.00. I backed out of CPS, switched to TUNER, but it still won't do more than 20-25 watts. I took measurements using a Cushman (no-autotune capability) as well as two stand-alone watt meters.
