K3s 100w Amplifier

I heard a rumor at Dayton that the K3s had two additional pins to handle
the current from the RF board, through the riser card, to the 100w
amplifier.

Can anyone confirm this?

Re: K3S 100w Amplifier

Schematics for the K3S are not up yet or that would be an easy read. 73,

In reply to this post by W0JFR

Actually it's four additional pins (was 6, now 10). This applies to P67B. There's a corresponding change to the KPAIO3A board.

Since we changed to gold pins for all of these connectors, we haven't had any further issues with +12 VDC to the amplifier module. These extra pins are just for insurance.

Are the pin assignments on P67B changed or is the connecter enlarged?
In other words, can an existing KPA3 and KPAIO3 be installed in a K3S
without damage to either the K3S/10 or the KPAIO3?

What are the new output devices?

The connector was enlarged.

Yes.

That will be clear when the schematic is ready to be posted.

Re: K3s 100w Amplifier

Is the converse also true - Can the new KPA3A and KPAIO3A be installed
in a K3? If not, how long cen we expect to be able to get KPA3s?
