I just downloaded and printed the PGXL Quick Start Guide AND the Owner's Manual. The Guide is 23 pages and the Manual is 27 pages. One of the biggest things I noticed when reading both manuals is that the PGXL software runs OUTSIDE the Flex Software. When using the amp, it has to be turned on in standby. The radio software has to be opened, then the PGXL software is opened and it finds the radio and the PGXL!
Neither manuals show a ground lug! Both manuals show a picture of the back of the PGXL AND identify every component.
The RF power bar graph red-lines after 1 KW. That's interesting!
For people using the Flex Radio and the PGXL, it will take 10 minutes to get everything up and running!
Every time the PGXL is turned-on , the fans go to max speed for a period of time to "blow-out the internal dust"!
That's got to be rough on the fan motors.
The manual refers to the input AC power as 110 or 220 Volts. The industry standard today is 120 and 240 Volts.
One of the pictures in the manuals shows the input voltage at 239 Volts. That surely exceeds their 220 Volts as stated.
" Automatic Power Control
Automatic power control is a system to reduce output power once it exceeds a preset threshold. The default factory threshold is set to 1800W. When peak power goes above 1800W APC will activate. The APC label will appear and power reading will turn red. Reduce drive power to have a total output power less then 1800W in order to deactivate the system. APC system was designed to prevent damage to the amplifier. "
Unless of course the SWR detected by the APC circuit is high enough to start throttling back the power sooner.

Can any of the alpha testers confirm which its? The main difference is either vertical flat blades (C13/C14) or horizontal flat blades (C19/C20).
The download is “Version 0” rather than a production release.
As for capabilities and levels of output where safeguards are enabled the present “Version 0” release descriptively is open to interpretation. If certainly doesn’t reflect the pessimistic interpretation that output has been throttled back some 10-25% from the promoted target.
Wondering if use with a Flex-6000 will have a number of configuration options that coordinate in different ways? And if a roll-out if all options would be ready?
Thinking we may see interface options using:
- 4o3a Windows Native Software in suite with other 4o3a software/hardware
- Hardware Band Control alone
- USB Hardware Band Control, again alone
- SmartSDR based integrated Control
- DDUtil based middleware-Control
- And perhaps others?
Looking really cool from “Version-0” documentation nonetheless!
Will be personally very interested in how the various parts all come together, especially as alternatives are thin on the ground and/or offer their own special issues to work around.
I’m also very interested in how the various 4o3a products end up working with each other. And what the antenna coupler/tuner looks like!
The documentation has a number of errors of this sort. We're working to fix them up right now.
I have questions open to them right now about the power supply. I "think" it is a large switching supply that will accept anything from 120 to 240 volts, 50 or 60 Hz, but that is only my guess. I'm waiting to hear something definite on this.

I assume the amp can be run standalone with radios other than the Flex, By standalone I mean without a computer running. Is there no frequency counter band switching like in Elecraft?
