K3 RTTY MMTTY, etc
Locked
 
|
I'd like to figure out how to get on RTTY by noon tomorrow. I'm working
with N1MM and MMTTY at the moment, with HRD and my trusty paddle as 2nd and 3rd back-ups. Transmit control - It looks like the K3 gives the option of having RTS or DTR actuate the PTT. MMTTY seems to use both, with no choice to use just one. I tried that method, but with serial port connected, the PTT was asserted at all times. Tried both DTR - OFF and RTS - OFF in the setup with same result. (First field is for PTT control and 2nd is for keyed line control.) Second choice is VOX. I set the K3 for AFSK A, connected line out of the PC to line in of the K3, turned VOX on, told MMTTY to transmit. No VOX operation. Plugged phones into the line out jack of the PC and verified -- yes, good strong RTTY tones being generated. I did try adjusting the MIC gain, which seems to become a line-in control for this mode. I also did go to the menu and chose Line In as the MIC input. What's left? I guess my third choice would be to use the serial port, have MMTTY send ACSII data, and the K3 would do the FSK thing. But I'm not sure how I'd get around my PTT control issues. Receive - Seems to be working. No RTTY on at the moment, but when there's a signal, I see it in the waterfall. PC / OS- I'm using a new Vista laptop. I know MMTTY isn't guaranteed to work with Vista, but I think it's working well enough that I should be able at least to operate the VOX. The rig control features of HRD are working fine.

Regarding VOX - have you tried adjusting VOX gain?

Hi Bob-
No, I had not tried that. It was at zero. I cranked it up to 25 and still no luck. Did some searches in the nabble archives and saw that it might need to be higher yet. So I went to 50 and now it keys the VOX. I have line in mic gain at about 20. Thanks for the suggestion. 73-Nick, WA5BDU Bob Cunnings wrote: > Regarding VOX - have you tried adjusting VOX gain? > > Bob NW8L > > > > _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

It demands a serial port dedicated ONLY to control of the radio, and a second port for PTT. 73, Jim K9YC _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hello Nick
I used to run MMTTY and now run a dedicated external modem and also HRD. However, I did re-install MMTTY to test it for you. The settings are: Normal serial cable to K3 (as used for firmware updates, etc.), no settings for PTT in the K3 menu (PTT-KEY OFF-OFF). I am using DTR/RTS PTT ticked in MMTTY, Kenwood settings from the drop down menu. For the actual RTTY keying, I use the dc input via the 15 way "D" connector on the K3 with the single transistor keying circuit from the MMTTY help file. It is found under "Prepare for FSK". I have a PC with 8 real serial ports which helps. The K3 is used with "DATA FSK D" mode. I do not use PTT from a serial port, the MMTTY program commands the K3 to TX via a Kenwood serial command. For HRD, I use audio to/from the sound card via the line in/out on the K3. Keying is via the serial cable and doesn't require any special configuration on the K3. Both of the above "just work"! 73 Dave, G4AON K3/100 #80 ---------------- I'd like to figure out how to get on RTTY by noon tomorrow.

Are you selecting the correct input for transmit audio (MENU: MIC
SEL)? Front panel (8-pin) vs. rear panel (3.5mm MIC jack) vs. LINE IN? _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Clarification please, Dave. How many serial connections are you using for the radio? Do you also use a contest logger? Which one? Does it share a serial connection with MMTTY? My experience is that if MMTTY is in use, two serial connections are required, even when the contest logger integrates it well. Are you doing it with one? 73, Jim K9YC _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Jim
I have 8 x serial ports available (2 from the PC motherboard, 6 from an additional card). I am not using a contest logging program with MMTTY, I am only a ragchrew operator on data modes. In the example below I am using two serial ports: There is one serial connection to the RS232 connector on the K3 (the one that is normally used for firmware updates, etc) and another serial connection to a single transistor interface that in turn connects to the FSK keying input of the 15 Way "D" on the rear of the K3. 73 Dave, G4AON K3/100 #80 =============== >/For the actual RTTY keying, I use the dc input via the 15 way "D" / >/connector on the K3 with the single transistor keying circuit from the / >/MMTTY help file.
