Flex-6600+DM780+Winkeyer = HELP!!!

I have a couple of WinKeyers, but I know nothing about your DM780… nonetheless, I'll try to help.

First: when you say "nothing is sent to the Flex" do you mean no CW is transmitted? I'm going to assume this is the case…

Your Flex 6600 needs the WinKeyer OUTPUT connected to the KEY jack on the back panel of your 6600. In the Settings, you'll need to make sure the IAMBIC setting is "Off" (this disables the Flex's internal keyer, and allows the Flex to simply follow the input key-closures… this is what you want when an External Winkeyer is used).

For an external hardware WinKeyer, no CAT port is needed or used. Just the WinKeyer out, to the Flex Key In.

Does this help?

(Another approach may be to get rid of your external WinKeyer altogether, and have the DM780 use CAT to talk to the Flex 6600 internal WinKeyer directly. Perhaps this is what you want to do …?)

Oh, now I understand more!

I think you have two solutions:

1. use WKRemote software on your PC. This can allow the Winkeyer that you use at your PC to communicate with the Flex's built-in Winkeyer. In this case, you use your paddles to send a character, then WKRemote sends the character to the FlexRadio, where it is translated back from character to key-up / key-down signals. As you may imagine, there is a latency between when you tap your paddles, and when RF actually goes out over the air. I never found this to be a problem, especially because the Winkeyer at your PC generates the latency-free sidetone.
2. I have, use, and love the Morconi keyer! Max provided a link in another thread. The Morconi is a keyer, that sends the key-up / key-down messages over your LAN to the Flex radio. It's essentially latency-free, and doesn't care if you send proper characters or not - the radio will follow your keying.

I highly recommend the Morconi keyer for your situation. There are some pre-built versions (Max sells one; others may too). Personally, I think having a version with a local speaker for sidetone would be great - mine doesn't have this, but there is a headphone-jack I can use.

HTH!
