How do you control which amp's relay engages during TX?
John KK9A From: Mark E. Musick I do this with my Alpha 9500. But differently than K9YC. I use the two antenna ports on the K3 and an Alpha Delta 2 position switch. Antenna one on the K3 goes to the KPA500 input. Antenna 2 on the K3 goes to the 9500 input. The output of the KPA500 goes to position one on the Alpha Delta switch. The output of the 9500 goes to position two of the Alpha Delta switch. The common of the Alpha Delta switch goes to the antenna switch. When I want the KPA500 the K3 is on ANT1 and the Alpha Delta switch is on position one. When I want the 9500 the K3 is on ANT2 and the Alpha Delta switch is on position two. Since the K3 remembers power by band and antenna, when I'm on the KPA500 regardless of band it has the correct power setting to give me 500 Watts or 200 Watts on 30 meters. When I'm on the 9500 the K3 has the correct drive power for the 9500 for that band. That is how I do it and it works for me.

Good question John.
You have to use the KPA500 KEY INTERRUPTER in this situation. It is attached at the KPA500 AUX. The AUX cable goes from the K3 ACC to the KEY INTERRUPTER that is plugged into the KPA500 AUX. If you have the KAT500 as I do the AUX cable goes from the K3 ACC to XCVR on the KAT500 then an AUX cable from AMP on the KAT500 to the KEY INTERRUPTER plugged into the KPA500 AUX. Then to control each amp's keying I have a RCA Phono Y plugged into the K3 KEY OUT. One side of the Y goes to the 9500 KEY IN. The other side goes to the KPA500 PA KEY or top RCA Phono PTT RLY connector on the KAT500 if you are using a KAT500. Then a key line jumper from the bottom PTT RLY RCA Phono connector on the KAT500 to the PA KEY on the KPA500. When both amplifiers are powered up, the one not being used is in standby. When in standby the amp will not be keyed. I hope all that makes sense. If not, let me know and I will try and clarify it.

Someone works the K3s with the ICOM IC-2KL amplifier?

I key the KPA500 and Titan in parallel, but only the one that gets RF
transmits. :) I can do that because the two amps use the same keying logic and the amp key line feeds a transistor. 73, Jim K9YC On Sat,10/22/2016 5:28 PM, [hidden email] wrote: > How do you control which amp's relay engages during TX? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

I key my KPA500 through the aux cable from the K3 and my 87A through my
microKEYER II. Only one amplifier is powered on at a time. 73, Jim N7US -----Original Message----- I key the KPA500 and Titan in parallel, but only the one that gets RF transmits. :) I can do that because the two amps use the same keying logic and the amp key line feeds a transistor. 73, Jim K9YC On Sat,10/22/2016 5:28 PM, [hidden email] wrote: > How do you control which amp's relay engages during TX? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
