Re: [Elecraft] K2 and N1MM+
I made a simple modification to allow this. I don't use ALC, so I repurposed the ALC pin in the interface connector. On the control board I added two 1n4148 diodes, cathodes to the former ALC pin of the connector and anodes to the dit and dah lines that go to the paddle. Then I connected that wire in the plug that goes to the computer serial port to the DTR pin. At this point all you have to do is activate the K2 feature that allows simultaneous closing of the dit and dah lines to be treated as a straight key, and set up N1MM for DTR keying. 73, Victor, 4X6GP Rehovot, Israel CWops #5 Formerly K2VCO https://www.qsl.net/k2vco/ On 07/12/2021 23:13, eda...@aya.yale.edu wrote: I need advice for getting N1MM+ to play well with a K2.

The K2 serial interface does NOT support DTR or RTS. It only supports three wires - TxD, RxD and Ground. One CAN run a K2 with KIO2 or KPA100 on a single serial port and key CW. But you have to build your own adapter to take the DTR signal and key the rig through the KEY connector. The adapter consists of a transistor and resistor, so it can be easily built into a connector housing.

Re: [Elecraft] K2 and N1MM+
Ted, You should be using the special cable from the PC (or USB to Serial adapter). That cable has no RTS or DTR wires in it, so it will not work for sending CW from N1MM. In other words, DTR and RTS are not implemented in the K2. Do NOT try to "fix" it by plugging the USB to serial adapter directly into the K2 - if it does not damage the K2, it will cause "strange happenings" in the K2 operation. Either a 'one transistor' keying interface, or a K1EL Winkeyer will have to be used between the USB to serial adapter and the K2 key jack to make N1MM send CW in the K2. 73, Don W3FPR On 12/7/2021 4:13 PM, eda...@aya.yale.edu wrote: I need advice for getting N1MM+ to play well with a K2.

Re: [Elecraft] K2 and N1MM+
Ted - Ultimately, N1MM+ needs to talk to a keying circuit which will then drive the KEY IN jack on the K2. I've had very good results, for example, with K1EL's WKUSB-SMT. I got that when I no longer had a PC with serial or parallel ports on it. In an earlier incarnation, I had N1MM drive a one-transistor keying circuit that was, if memory serves (it was a while ago), connected to a serial port on my PC ... and defined as such in N1MM.

Re: [Elecraft] K2 plus N1MM logger in CW
Hi all, Many thanks to all who replied. I updated N1MM logger to the most recent version, re-edited the macros in the manner described by K4MTX in his blog (who did it for the KX3) and it seems to work with the K2 as well. There seems to be enough space in the connectors of the pseudo-serial cable for the one-transistor keying circuit, so I will add it to the cable later and see how well this works - with the system sounds off. I hope, I have the date right - happy Thanksgving!

Also there was a note on NL+ reflector suggesting that when using a USB/Serial adapter as the interface between the PC and the radio, one should change some parameters. Open Windows Device Manager and select the Ports (COM LPT), select your COM port, then Port Settings, then Advanced. Change both Rx and Tx (Bytes) to 64. Then drop down to Latency Timer and set that to 1ms.

Re: [Elecraft] K2 plus N1MM logger in CW
Ralf, I cannot answer your N1MM question, but I can answer with certainty about the K2 'special cable' - Yes, the 'computer' end of that cable can be plugged into a USB to serial adapter. Just do *not* plug the adapter directly into the K2 AUX IO connector. You may find some USB to serial adapters that will not work well at the slower 4800 baud rate used by the K2. Try to find one with an FTDI chipset. 73, Don W3FPR On 11/25/2014 7:24 AM, DL6OAP wrote: Will the special serial cable work with a serial to USB adapter? __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K2 plus N1MM logger in CW
Thanks for the replies (also to Dave and Pete who replied off the list). I am aware of the approach that keys the K2 with the one transistor-circuit using the CTS/DTS control line, but will be running a small netbook under WindowsXP - mainly because this computer produces less rf noise than my other two - so I am not sure if I will have the latency issue or not. I always liked the Winkeyer solution more (I have a Microkeyer interface, but no cable for linking the MK to the K2) But it is worth trying. When I got the K2, I used the parallel port of my old laptop (with CT software, I think) with a similar one-transistor circuit for keying, but was not completely satisfied - using this K2remote tool from the Elecraft webpage (using the KY method), the keying sounded much better to me. In my understanding, sending just the textstrings to the KIO-interface and let the K2 form the dots and dashes should be closest to the Winkeyer solution, and would only use ressources that I already have. I think I will test the macros on the KX3 first and then try my USB-serial adapter with the K2 (the adapter works with a rather old Garmin Geko handheld GPS, am not sure about the Baud-rate, but I think it also is at 4800). If this is not working, I will try the CTS/DTS method...

Knowing now that Elecraft radios with IO interfaces have the ability to send CW without an external box, why would anyone bother with external electronics?

When I got the K2, I used the parallel port of my old laptop (with CT software, I think) with a similar one-transistor circuit for keying, but was not completely satisfied - using this K2remote tool from the Elecraft webpage (using the KY method), the keying sounded much better to me. In my understanding, sending just the textstrings to the KIO-interface and let the K2 form the dots and dashes should be closest to the Winkeyer solution, and would only use ressources that I already have. I think I will test the macros on the KX3 first and then try my USB-serial adapter with the K2 (the adapter works with a rather old Garmin Geko handheld GPS, am not sure about the Baud-rate, but I think it also is at 4800). If this is not working, I will try the CTS/DTS method... -- - Northern California Contest Club - CU in the Cal QSO Party 3-4 Oct 2015 - www.cqp.org __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

The issue is how N1MM sends CW on the serial port, which can get choppy when it is interrupted by other software running on your computer. WinKey is a very good way to send CW from a computer. It works quite well for me. At low speeds, and under the right conditions on the computer, you can send CW on the DTR pin of the serial port. It even works with USB to RS232 adapters. You need a simple transistor inverter to convert the keying signal to a short between the keying line and the chassis. Collector to keying line, emitter to chassis, DTR through 4.7K to the base. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

On 11/25/2014 4:24 AM, DL6OAP wrote: However, I found some hints about directly keying a KX3 without any additional interface by wrapping the KY command in N1MM's CATA1ASC command inside a function key macro. I have not checked in detail but my feeling is that KX3 and K2 use the same command structure for CW keying with the KY command. True. You can use the CATA1ASC command in any N1MM function key macro to send commands ... any commands you want. For SS SSB, I record my CQ and exchange in the K3 DVK memory and then use the function keys to send SWTxx commands to emulate tapping the M1 or M2 keys. Will this approach work with a K2 as well? I believe so. Will the special serial cable work with a serial to USB adapter? Yes. Be aware however that the 9-pin D connector on the back of the K2 is *NOT* an RS-232 serial port. 3 pins [Gnd, RX data, and TX data] are RS-232 levels. The other pins are not. Do not plug the USB-serial adapter directly into the K2 port. Has anyone tried this already? Yes, and it works fine, subject to the usual disclaimers about Prolific vs FTDI vs Chinese knock-off USB adapters. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K2 plus N1MM logger in CW
This is one of the very few times I have to disagree with Jim! N1MM and NL+ keys my K3 flawlessly up to about 95 wpm. Having been a QRQ operator, running speeds up to 120 wpm, stuttering CW is something I just can't stand. If one is using the Windows operating system, YOU MUST GO INTO THE OPERATING SYSTEM AND TURN OFF WINDOWS GENERATED SOUNDS!! For about the 30th time, the reason for that is because when Windows generates its internal sounds, the CPU first SHUTS OFF THE I/O PORTS, generates the operating system sounds, then turns the I/O ports ON again; and that is why Windows generated CW 'stutters'. Shut off the Windows sounds generation and the CW output will be as clean and stutter free as any external purchased CW generator. 73, Tom - W4BQF -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Brown Sent: Tuesday, November 25, 2014 12:29 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K2 plus N1MM logger in CW On Tue,11/25/2014 9:09 AM, Byron Servies wrote: My K2 sounds great to me, as the operator, when using a paddle.

Re: [Elecraft] [K2] K2+N1MM
Fred, What Operating System are you using? Does it work properly with the K3? If it's a Windows OS. You can change the baud rate by going into StartSettingsControl PanelSystemHardwareDevice ManagerPorts and find the one labeled USB (most likely name) with COM5 after it. The default baud rate is usually 9600. If I recall correctly the K2 should be 4800... Hopefully this will clear it up. 73, Julius n2wn Fred Jensen wrote: Anyone got any ideas why N1MM logger periodically puts up the lost comm box when it's controlling my K2?
