Re: [digitalradio] FT-920 Setup for RTTY ???
and you worked St Kitts too ! Well done. Andy K3UK On 2/4/07, Dave Sloan <[EMAIL PROTECTED]> wrote: Thanks for all of the assistance. I went back and reread the FT-920 manual (novel idea)! When you use the data plug on the back of the FT-920 you set the mode to data USB for both PSK and for RTTY. Then through the menu you have to change the factory default for the shift for the AFSK. This actually causes the radio to use LSB for RTTY like everyone was saying. But the display panel shows data USB. Then I went in and set the WinWarbler config for RRTY to AFSK USB RTTY no "Mark Offset" and the default value of 2210 for the "Optimal Offset". I called CQ 3 times and V44JK responded.

Set MMTY for normal shift, 170 hz shift and usually 60 wpm (45.45 baud). The frequency of the mark tone and space tone (as long as it is shifted the correct ammount from the mark) does not really make any differance. Usually you will want to use 2125 for the mark tone. Try to set the mark tone to over 1500 hz if you do not use 2125 as this puts the 2nd harmonic past the sideband filter's cutoff . PSK is usually sent on usb. RTTY can be confusing to set up. YOu can set the rig to LSB and the program to normal. That is ham normal, comercial normal is the opposit. Don't ask me why it is done this way, I have only been playing with rtty for about 30 years.. You can also set the program to reverse and set the lowband rig for USB and it will work just fine also. This is not normally done, but it will work. That is where the confusion can really come in. Expecting? Get great news right away with email Auto-Check. Try the Yahoo!

Re: [digitalradio] FT-920 Setup for RTTY ???
In Winwarbler I have the xcrv mode set to AFSK since my old radio does not do true FSK. I use the default offset which is 2210. I use Multipsk and sometimes Winwarbler for RTTY. Andy K3UK

Usually, LSB is used for RTTY and USB for all other digital modes. Ssince you have your radio set for Data USB , I assume this is why you have to used reverse to receive RTTY. I can't comment about FSK versus AFSK since I am not familar with your radio. For my radio, I have Windwarbler set for AFSK, LSB. Hi Andrew, Your comments make since. So RTTY normally uses LSB, while PSK uses USB? What do you have the "xvr mode" set too? Do you have any "mark offset"? Is your Optimal Offset 2210? So far I really like the DXLabs suite. Which of the programs do you use? What do you find the most useful? TNX & 73, Dave N0EOP

I have the settings in MTTY set to the same as a friend who also has the FT-920 and RTTY is working great for him. The only question I have about these settings is the Misc, Soundcard Device ID setting. I haven't tried other setting that what by friend uses. Could this be where the problem is? I am using the DXLab program WinWarbler. I have to check the Reverse to be able to receive. The program controls the transmitter without any problem but I can't seem to make any contacts. Anyone have any ideas on what I should try next? THANKS, Dave N0EOP -- Andy K3UK Skype Me : callto://andyobrien73 www.obriensweb.com
