Subject: KX3 CW from computer

Tony,
Essentially you have it right. It will take a break-out of either RTS or DTR interfaced by a NPN transistor and one resistor connected to the KEY Jack. I can see innovated folks making the circuit inside the jack with sm transistor and resistor and adding wye jack for connecting the paddle. External keyer not required since you can use the menu CW KEY1 and CW KEY2 to switch back to using the paddle from HAND. Instant change over to the paddle then the keyboard is not possible, but why would one do that? I use keyboard CW on eme so that I do not have to deal with sending by key (mostly I have scripts made up), but I do not operate a lot of CW on HF so maybe there is a reason to go back-n-forth rapidly. For the keyboard CW program I run, you need both RTS (for PTT) and DTR (for keying), but that sw does not support QSK. So for me to implement computer CW I will also need a breakout to the mic-PTT line. PTT is needed for the digital sw I run, anyway. I have an old switch box that I am planning to use for I/F of the serial lines to the KX3, plus Tx audio. It already has 3.5mm mini-phone jacks and DB9 connectors for an old setup I used way back in time for I/F my FT-847. There are many after-market computer/radio I/F to accomplish this and a few are very small which would be appropriate for portable operation with the KX3 and a laptop. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?

The KX3 has two independent keying inputs. I like connecting the
external (computer generated) key line to the left side panel KEY-IN jack for the automatically generated stuff and use the front-side keyer paddle for manual sending. The KX3 menu allows setting either or both inputs to either paddle or 'straight key' input. I changed the left-side jack to the hand key setting on the 3.5mm TIP and left the front panel jack at its default PADDLE setting. Slick. (In my humble opinion, of course). 73 de Bob, K6XX On 3/12/2012 9:10 AM, Edward R. Cole wrote: > Tony, > > Essentially you have it right.

"Instant change over to the paddle then the keyboard is not possible, but why would one do that?" The need to quickly jump in with the paddle happens often enough in contesting to make that a pretty important capability. Most contest loggers have a limited number of CW macros available and they won't cover everything. Temporarily switching to keyboard CW is possible but for me at least is clumsier than just moving my hand to the paddle. 73, Dave AB7E On 3/12/2012 9:10 AM, Edward R.

It's not quite as ugly as that, however, because Bob K6XX points out that the Y-connector capability is built in to the KX3.

Dave,
OK, well I guess there are many different types of sw that generate CW. The program I use allows you to write scripts for the Function Keys on a computer or to merely type from the keyboard real-time. It was written to support CW on eme so it has built in TR programmable delay times and separate control of PTT and KEY, since one does not want to hot switch 1kW at 1296 MHz! So I see the opinions being given coming from total different perspectives (some are using HF loggers, some contesting sw, some HRD or other radio sw, some are using eme digital sw. Each is working a little differently so a solution that fits all may not exist. 73, Ed - KL7UW ------------------------------ Date: Mon, 12 Mar 2012 10:08:06 -0700 From: David Gilbert <[hidden email]> Subject: Re: [Elecraft] Subject: KX3 CW from computer To: [hidden email] Message-ID: <[hidden email]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed "Instant change over to the paddle then the keyboard is not possible, but why would one do that?"

I'm trying a different approach to a workaround for this, and now I
have a macro programming question: I can send keystrokes to the K3 via a macro like KY: HELLO. But there's a catch. MixW formats its macros like this: <CATCMD KY: HELLO> This sends the HELLO, but unfortunately the terminating '>' is also sent as 'IF'. Don't know why that is interpreted as the letters 'IF', but anyway, it would solve my problems if I could get he K3 to ignore that character. I tried terminating it with '@', but that didn't work as I expected. It had the result of not sending the HELLO, but it sent the IF anyway. If one of the macro experts can solve this one, I'll be a happy guy.

Can you add a semicolon between HELLO and >? If you send a KY HELLO;>; to
the K3, the >; should be ignored as an "invalid" command.

It looks like there's a good opportunity here for a KX3 accessory that
Elecraft or some third party could make: a custom serial cable that plugs into a serial port at the PC and terminates in plugs for PTT and key at the KX3. The required circuitry could be built into the connector shell. You should be able to steal enough juice from the RS232 port to power it all. It'd be really neat if SMT versions of the K1EL chips were available. Then a WinKeyer could be built into a cable.

That works, and in fact the MixW parser works too, so I can put variable names in the macro and have them evaluated at runtime. This is terrific. 73, Tony KT0NY -- http://www.isb.edu/faculty/facultydir.aspx?ddlFaculty=352 ______________________________________________________________ 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 |
