[Elecraft] Sending AFSK RTTY

[Peter Dougherty]

Before I start messing with FLDigi, I would really rather prefer to get it working with the native DX Lab Suite first, and why I mentioned it in my initial post. Adding more software that I don’t (and will never) understand is the very last thing I want to do unless there is no way around it.

When I used FSK with the MicroKeyer it was dead simple, RTTY filtering came up as a default in the radio (twin peak filtering) and it worked with almost no configuration. I would like to have something similar using AFSK and USB connectivity—specifically the twin-peak brick-wall filtering. Right now, just switching in to RTTY mode in WinWarbler just puts the radio into LSB mode and that’s it. 

Like I said, I really need to get this working with WW if it’s compatible. I’ve had maybe 3 hours of sleep per night for the last 3 nights playing with this radio, N1MM, and DX Lab Suite, and I’m almost no further ahead than I was 3 nights ago. All I have is CW via WinWarbler and full manual control. CW sending and /RTTY tone just won’t work for me so far. Everybody was saying last year that it isn’t that hard to do….yet here we are!

Peter,

    I'm not that familiar with Winwarbler, but I do run AFSK when using RTTY. You could use DATA A on the K3s or AFSK. I prefer to use the AFSK mode as it appear to work better than just using DATA A. The set up should be about the same as you are using for FT8 using the radio's built in sound card for the software you use; I prefer FLDIGI just because.

 

    The K3s does do FSK, but I'm not sure there is a real advantage over running in the AFSK mode with some digital software. The data mode as you call it is DATA A on the radio. It means you can feed the output of some digital software into the radio and use any available bandwidth. It also turns off the equalizers and compressor. AFSK has a filter for each tone.

 

    I'm not sure why you have had some much difficulty as I would estimate it shouldn't take more than one day. ;-)

 

    As you have a K3s, the set up really shouldn't be a lot of trouble. Start by downloading FLDIGI and connecting the radio using the USB connector.  This allows both control of the radio and audio in and out. Set the sound card in FLDIGI to USB CODEC line in and speaker out. The radio will reflect a com port that will be used for control, use it at 38,400 8N2. Now you're set to go. Use the mic control on the front of the radio to set the level for the transmitter such that ALC will show 4 bars and a flickering 5th. The power level should be set with the knob that controls power. This should be how you set up for FT8 using WSJT-X. All you need to do is set op mode in FLDIGI and go. Have fun!

I haven't sent AFSK RTTY in almost 18 years so I'm not sure how I should set

my K3s up for it. I will be using it with DX Labs WinWarbler exclusively (I

don't do RTTY contesting, so no need to get it working with N1MM). I have

the radio setup for USB communication exclusively. Before this I had a

MicroKeyer-II and was sending FSK. Given the rise of FT8 I doubt I'll be

doing much RTTY anymore, but I still need to have it available just in case.

 

Using WinWarbler, I don't see any option to use a data mode for RTTY, just

LSB (again, we're talking AFSK now). Isn't there a data mode built into the

K3s for RTTY? Or is that just for FSK? Or is it a case of only using data

mode for one (and only one) data format? At the moment, I have the radio

using Data mode for FT8.

 

Sorry for the confusion-it's been three days of trying to find the right

settings for everything, with only very limited success. Thanks as always.
