KPA500 Beta FW 1.54

What changes were made to FW Version 1.54 for the KPA500? The notes
only go to version 1.52. Or is this just a typo causing the utility to
show it as 1.54 when it is actually 1.52?

Re: KPA500 Beta FW 1.54

V1.54 corrects a bug introduced in V1.52 affecting the Power Adjustment feature. This feature allows you to calibrate the measured power against a calibrated good power meter.

If you installed the V1.52 beta it is highly advised that you update to V1.54 as it becomes available.

V1.52 corrected a very rare issue with the amplifier changing bands unexpectedly when operating in SSB mode. We want our products to be as good as they can
possibly be, thus we addressed this issue.

V.154 is now being phased in as the production version for shipping KPA500s.

In reply to this post by Michael Eberle

The KPA500 utility showed 1.54 available when I clicked "Copy New Files
from Elecraft." The firmware page on the website still shows 1.47 as
the latest production release. Apparently I caught the update with the
utility before they had a chance to update the web page.

Re: KPA500 Beta FW 1.54

The elves down in Watsonville have been incredibly busy the last few weeks. Most things got done, but a few are still on the “to do” list. Updating the KPA500 firmware web page is one of those.
Obviously the latest version (1.54) made it to the web site for the KPA Utility to find, and I can verify that V1.54 is indeed a released version.

Thanks for reminding me about this. I had been watching the firmware web page and forgotten about the KPA Utilitiy’s ability to perform magic.

73!
