How do you have ALC connected? Are you using a Flex? I don't have any ALC connection to mine and I can easily drive it to 1700 watts on most bands, except 6m. Anything past 1700 and it will start to limit in my case. This was tested into a 1:1 dummy load.
While I can get the amp to 1500 on 6m it heats up so fast it is mostly not usable at that power for me. At 1kw it does "ok" but still heats really fast. I'm glad I have it in a shed outside next to my house. Not only is it cooler in there but I can't hear the crazy fans when on 6m.

Hi I ment APC (Automatic Power Control) in the amp that limits output power to a safe level it should be at 2000W on most bands 1650W on 160M and 1750W on 20M but my amp is limiting at below 1500W on 6M, 20M and 160M. My amp is working good on 6M up to 1300-1350W and then the APC come on and limits the output. I opened a ticket but nothing happening1

Ya ok... Well mine lets me set 1700 on most bands unless the SWR is too high.

I have noticed this same issue where APC is jumping in and limiting power on 20meters well below the established specs. This was not an issue for me prior to the latest firmware update for the PGXL. I suspect it may have something to do with region. Again this behavior was not seen prior to the latest firmware.0

We agree that ALC is not the tool you want to use for this. (It is way beyond what I want to get into at this point),
The PGXL is limited to a total gain of 15db for US customers. This can take you beyond 1500 watts if you are not paying attention, but, under the terms of your license, this is something you, as the operator are responsible for. This is the joy about the Amateur Radio License.
@sschrack, if you are having a different issue, please open a support ticket. For you, this is a different issue.

@Mike-VA3MW Hi Mike yes I did open a ticket and my issue was resolved. ALC mentioned in the first post I believe was a typo. My issue was in the latest firmware it was limiting power on the three mentioned bands below stated US specifications. The behavior did not occur prior to me upgrading to version 3.6.21 I received excellent support and the issue was resolved. If anyone else is experiencing a similar issue. Open a support ticket they helped me.0
