AFAIK, the only 'downside' is that you need to run the separate PTT cable.

The rev B manual is not yet available for download via the web page. I have built my own cable without pin 11 connected between the K3 and KPA-500. This raises the question then- what , if any, is the disadvantage of leaving pin 11 disconnected to allow the K3 to control the PR6 preamp, while using the KPA-500?

That was indeed the case with the one I received. I broke off pin 11 in the connector so that I can continue to use the DIGOUT1 signal to control my PR6 preamp. 73, Ken K3IU Portsmouth, RI On 6/29/2011 3:35 AM, Bruce Beford wrote: I'd like some confirmation of this. I can see in the KPA500 manual (rev A, page 16) that pin 11 of the AUX connector is INHIBIT#. That's fine. Pin 11 on the K3 AUX connector is DIGOUT1, OK. However, also in the KPA500 manual (page 17), the wiring for a cable between the K3 and the KPA500 does not use pin 11. I have constructed my K3-KPA500 AUX cable according to this table, in anticipation of receiving my KPA500 kit later this summer. If this table is correct, I cannot see how DIGOUT1 affects the KPA500. If in fact, It does inhibit the KPA500 (auto-magically, without being connected), does this mean that DIGOUT1 can no longer be used to control the PR6 preamp, when a KPA500 is connected to a K3? Somewhat confused in NH, Bruce, N1RX Make sure that DIGOUT1 is turned OFF from the K3. Turning it on disables the KPA. Note that this is a per-band function, so it needs to > be turned off for each band you wish to use the KPA500.
