You do not need the "CATA1ASC " commands to key the K3/K3s via the CAT control link.
Look here: <http://n1mmplus.hamdocs.com/tiki-index.php?page=Supported+Radios&structure= N1MM+Logger+Documentation#K3_and_K3S> The K3 can accept PTT switching from several sources, including: a keying circuit from a serial or parallel port to the K3's PTT IN; PTT from a Winkeyer; RTS (pin 7) on the radio control RS232 port; using "Radio PTT via command"; or VOX It is better not to use multiple methods of PTT control in parallel; in some cases, and depending on which version of firmware is installed, doing so can leave a K3 stuck in transmit at the end of function-key messages. You should not check "Radio PTT via command" if you are using RTS on the radio control port, or any other hardware PTT connection, to control PTT ** Procedure for configuring RTS on the radio control RS232 port: Starting with the K3's CONFIG:PTT-KEY set to OFF-OFF, check the CW/Other box beside the radio control port in the Configurer and configure N1MM+ to control PTT from RTS on the radio control port (Port setup), and then set the K3's CONFIG:PTT-KEY to RTS-OFF (or RTS-DTR if you are also using CW via DTR) Warning: leaving RTS set to Always on with the K3's CONFIG:PTT-KEY set to RTS-OFF or RTS-DTR will cause the K3 to be permanently in transmit The K3 accepts CW keying on DTR (pin 4) of the same COM port you're using to control the K3. This method can be used when other methods (e.g. Winkeyer or a keying circuit on a separate COM or LPT port) are not available CW and radio control on the same COM port do NOT work in SO2R mode CW on DTR does NOT work with some USB-to-serial adapters (e.g. Prolific chipset - may depend on the driver version) CW on DTR may be missing some capabilities and may have other undesired side effects - use at your own risk ** Procedure: Starting with the K3's CONFIG:PTT-KEY set to OFF-OFF, check the CW/Other box beside the radio control port in the Configurer and configure N1MM+ to use DTR for CW on that port; set the K3's CONFIG:PTT-KEY to OFF-DTR (or RTS-DTR if you are also using PTT via RTS) Warning: leaving DTR set to Always on with the K3's CONFIG:PTT-KEY set to OFF-DTR or RTS-DTR will cause a permanent "key-down" condition 73, Ted W4NZ -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Dauer, Edward Sent: Wednesday, August 01, 2018 7:33 PM To: elecraft@mailman.qth.net Subject: [Elecraft] Using N1MM to Key a K3 with no outboard keyer The following may test our commitment to the idea that there is no such thing as a stupid question . . . . I finally got around to setting up my N1MM logger to key my transmitters without having to use a K1EL or any other keyer -- just the KUSB cable directly from the PC into the rig. After hours of frustrating failure, by lucky accident I came across a post on the Internet that gave examples for programming the Fn keys, using N1MM to key a KX3. Each command line contains the string CATA1ASC before the command KY. Without the CATA1ASC, hitting the Fn key does nothing. With it, and with the standard KY programming command, it works -- on the KX3 at least. My K3 is at my other QTH so I haven't tried this on that rig yet, but here's my question -- what is the CATA1ASC for? I did a word search in both the KX3 and the N1MM manuals, and in the KX3 Programmer's Guide, and I could find no mention of the CATA1ASC string. Had I not found the examples on the Internet accidentally I would still be trying to make this work with no success. So can someone help me understand what it's about and why I didn't see it in any of the manuals? Is it something in Windows 10?
