Self Check failure

Erik Carling EI4KF

I have a new PGXL, 7 days old. Today I powered it up and in the Self Check that runs, it returned 'Power Supply Fail' and 'Calibration Fail'. I cycled the power and the Self Checks passed OK. So why ask a question here when there is no current issue? I just wonder if the Self Check failures, according to users' experience, can occasionally fail inexplicably or whether I should be concerned about a real problem. It being new, it could be returned though that would be an arduous task not to be undertaken unnecessarily.

Anyone any thoughts please.

Thank you, Erik

hi Erik,

I have not heard of that particular error but during boot process the power supply will report an error if the fans in the power supply are not running within the specified RPM range. The power supply fans runs all the time and are separate from the RF palette fans which can have the speed changed (standard, contest, broadcast).

I recommend you reach out to 4O3A support. They can help you to do some checks before possibly the inconvenience of replacing the amp.

OK I will do that, thank you.

Is it best practice to shut off the power using the rear switch after each operating session or to leave it powered? Or does it not matter one way or the other?

Hi Erik,

I have had my PGXL plugged into 220 VAC and powered on since April 2022. There have been a couple of times that it lost my network connection and that I have had to recycle the power by the rear switch, but never had a self check fail. So it has been powered up for 2 years and 8 months. I try to remember to put it in Standby when not in the shack, but most days and nights it remains in Operate mode. It would be nice to have a "sleep mode" after so many hours of inactivity.

73, Bill

Hi Bill. Ok, and if you know, does it draw much power when left in that state? Not that I am a miser but in Ireland, being akin to a 3rd world country, electricity prices are outrageously high.
