Anyone come up with a way to interface the Quadra amp to do automatic band switching with the 6000 series rigs without using N4PY?  I also run HRD interfaced with the rig.

I’m pretty sure you can feed BCD from the Flex ringht into the Quadra. Look for the USB document in the downloads area. Mike

And, here is the USB document that will help out https://www.flexradio.com/downloads/usb-cable-interface-guide-pdf/

Mike in your diagram you show "red x" on the band data 1 connector for pins 1 and 7. Pin 1 which is auto on and also pin 7 which is data 3. Any reason for that...am I missing something?

Thanks,

That portion of the diagram was copied from another diagram detailing connection via parallel port with DDUTIL. If using Band Data 1 connector you would connect nothing to pin 1. Not sure what the purpose of the red x was. Just ignore red x.

Thanks a lot Mike for the response. I am going to use band data 2. Band data 1 is already connected to FT1000MP. I do want the ability to provide auto-on via app running on desktop so I can remotely turn the amp on and off. So I believe that means I have to supply 13.5V to pin 1 to turn amp on. I will have to verify that part. Anyway thanks for clarification and providing the information.

If I understand what I've read, you should not use both connectors. From what you described you will have the 1000MP on band data 2 and Flexradio on band data 1. Yaesu says one or the other NOT both, if you do you run the risk of damaging the amp or the radio.

Harry W0LS

Ok...understand..so in that case I would leave the connection to the MP disconnected and only use the one coming from the Flex. If I needed to use the MP connection to the Quadra I would have to disconnect the Flex and plug the MP connector in....got it...thanks.

We checked that. Weird thing is that I got it to work once. Its just too flaky.

It's a USB to BCD cable. Hard to test the lines. My bet is on the amp.

Just received my C323HM-DDHSL-0 Cable and installed a 15 pin Din connector, Plugged it into to the Quadra and it follows the 6600M perfectly.

Thanks Mike VE3CKO and others on this topic.

Glad I was able to help. It is with some sadness thought that I will be surrendering my Quadra shortly and putting it up for sale. Won't be sad too much because I have a PGXL on it's way.

Thank you very much, Mike! I have ordered the cable from Flexradio and the installation to a DB15 connector and the setup of my 6400 was a very easy exercise following the description. Everything works fine from 160 to 6 m except 60m, which is a cosmetical issue somehow because I will not use the amp on 60 m most probably but still annoying. The Quadra works on 60m together with my old YAESU FT1000MP MKV, I had modified to transmit on 60m. So the question is if something needs to be modified in the Flex settings. Any help would be nice.

Really? I have run two radios into my Quadra when doing SO2R with no problems - not for some years I must admit. G4LDL.
