I have purchased two LP-Pan units from among the several offers I received.
I may sell my SDR-IQ after I compare performance with the LP-Pan. But not listing it yet. The LP-Pan may make the SDR-IQ redundant for my station. I do use it to monitor 500-KHz but the K3 is exclusively used as exciter for transmitting on 500-KHz. ---------------------------------------------------- Date: Fri, 21 Jan 2011 09:17:55 -0900 From: "Edward R.

Hi all,
I can control the K3 over the rs232 cable. No problem. CW en PTT also works over the same cable with the PTT-KEY settings on. VERY NICE!!! Keeping the winkey as a backup now. Now the question: Is it possible to run RTTY in FSK D over the rs232 cable directly into the K3 just like the CW keying? 73 Arie PA3A ______________________________________________________________ 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 |

Yep. Set up FSK D, turn TEXT DEC on and go to the Terminal program in
the K3 Utility. Lots of RTTY on today.

Arie,
I assume you are asking whether it is possible to use the RS232 port to send FSK RTTY in FSK D. If so, the answer is yes. Below are three theoretically possible methods - only the third one works, and only from a limited selection of software, but it is possible. The K3 does not accept direct ITA2 (Baudot RTTY) FSK keying on DTR or RTS, and even if it did, there is no software that I know of that would be capable of sending FSK using the same serial port as is used for radio control. The K3 can accept Morse code input and convert the Morse code to ITA2 RTTY in FSK D, but only from its internal keyer (either from paddles or from one of the memory keys on the front panel). The CW-to-DATA converter does not accept CW from an external straight key input, from an external keyer such as a Winkeyer, or from DTR or RTS on the RS232 port. However, there is a software command that you can use to send ASCII text to the K3 to be transmitted in FSK D. It's the KY command (see the Programmer's Reference). I believe that the K3 Utility and G4ILO's KCOMM software can use this command, but most other RTTY software (such as MMTTY) cannot. So, by using KCOMM or the K3 Utility you can send FSK RTTY from the K3 without an FSK keying circuit connected to the AUX connector. 73, Rich VE3KI PA3A wrote: > I can control the K3 over the rs232 cable.

Thanks Rich, clear answer.
Well... The idea was to use LP bridge. Send the RTTY keying via a com-port from MMTTY, and control the rest of the K3 via another com with N1MM logger. Since there's only one cable to the K3, all signals should run over the same cable, just like the combination of rig control and cw keying over DTR. I donot know whether it would work, but if it would, then K3 is up for a new menu item: RTTY via DTR :-) 73, Arie PA3A Op 22-1-2011 23:38, Richard Ferch schreef: > Arie, > > I assume you are asking whether it is possible to use the RS232 port to > send FSK RTTY in FSK D.

Arie,
You will have to ask Larry Phipps if that MMTTY stream is implemented in LP-Bridge. RTTY via DTR is possible, but would require the "one transistor keying circuit" to drive the PTT-IN pin on the K3s ACC connector. Of course, LP-Bridge may or may not support DTR through its interface. 73, Don W3FPR On 1/22/2011 5:52 PM, Arie Kleingeld PA3A wrote: > Thanks Rich, clear answer. > > Well... > > The idea was to use LP bridge. > Send the RTTY keying via a com-port from MMTTY, and control the rest of > the K3 via another com with N1MM logger.

The MMTTY/EXTFSK combination can use DTR on a serial port for FSK
keying, but I have no idea whether EXTFSK would work through LP-Bridge. Without EXTFSK, MMTTY uses TxD for FSK keying, not DTR, and that cannot be shared with radio control. If you are already using MMTTY, by any chance does that mean that you have an audio cable from the K3's LINE OUT to your computer's sound card? If so, a second audio cable from the sound card's output to the K3's LINE IN is all you need to do AFSK RTTY. The K3's AFSK RTTY is just as good as its FSK RTTY, so there is no reason to insist on FSK. 73, Rich VE3KI PA3A wrote: > The idea was to use LP bridge. > Send the RTTY keying via a com-port from MMTTY, and control the rest of > the K3 via another com with N1MM logger.

Rich,
Yes, I have RTTY working in AFSK mode. I am trying to make it as LEAN as possible. If MMTTY can bring the FSK as a digital signal which can be fed into the K3 as digital signal (0/1) that would be nice and Lean. Just as N1MM and CW over one cable for the K3. Of course I can use two cables, one for N1MM rig control and one for MMTTY and feed that to the ACC connector using an optocoupler or so. Again, not as lean as the nice CW solution. 73 Arie PA3A Op 23-1-2011 0:37, Richard Ferch schreef: > The MMTTY/EXTFSK combination can use DTR on a serial port for FSK > keying, but I have no idea whether EXTFSK would work through LP-Bridge. > Without EXTFSK, MMTTY uses TxD for FSK keying, not DTR, and that cannot > be shared with radio control. > > If you are already using MMTTY, by any chance does that mean that you > have an audio cable from the K3's LINE OUT to your computer's sound > card?
