One minor issue with the KPA500

[Richard Squire - HB9ANM]

My KPA500 is working like a champ with my K3 and AUX cable.
But I noticed when BAND CHG is set to STBY (which I prefer in order to avoid tuning my dipole on the new band with 400 W instead of 20 W by mistake!), the KPA500 does go into STBY when changing bands but the K3 keeps the lower power setting and does not return to 100 W. This does not happen if BAND CHG is set to NOR.
Anyone else noticed this?
I guess that can be resolved in some future FW release

Richard,

I noticed the same thing with my new KPA500.  I searched the archives and found this note from Jack at Elecraft.

Dave, N4QS

This is a timing problem in the communications, and will be fixed in the next firmware release.

Thank you Dave and thank you Jack for your e-mail.
Glad to know this minor problem is known and will be solved soon.
I'm very happy with my KPA500-K S/N 107 which arrived on Monday and was ready for a smoke test in the (very) early hours on Tuesday morning, hi! All went smoothly as usual and the KPA500 is a joy to use. It's so well integrated with the K3, like having a 500W transceiver...
I've had 2-3 other linears but you can't beat the KPA500.
You can't beat the K3/KPA500 combination.
And you can't beat Elecraft! Thanks!

This was supposed to be a timing problem to be resolved with the next FW release but FW 1.11 didn't solve it. Any one else noticed this?
Not a big issue but I'd like to go for BAND CHG = STBY...
Anyway, the KPA500 is joy to use.

Richard,

Yes, I have noticed this also.  I hope they can fix this.

This _was_ fixed in the V1.11 firmware. I will be contacting you off-list to get more details to determine why it may not be working in your setup.
