K3S sending gibberish FSK
 
|
I have a K3s (upgraded K3) and K3S (factory built).
Keying is being done with a MORTTY device. I tested with MMTTY and N1MM+/2Tone. The K3s is working just fine. So I understand the setup. Same programs, same setup, but NO ONE can decode the K3S. All I see is gibberish in the Window during TX. As far as I can tell, it is setup identically. I have gone through the Fred Cady book. What am I missing?? Suggestions??

Will,
Are you using DATA A mode? The normal sideband for DATA A is USB which works with most all soundcard data modes. If you are using USB mode instead, I suggest you change. Using Sideband mode for data modes requires you to turn off compression and set the equalizers flat - DATA A mode does that for you automatically, leaving your sideband mode settings intact. Do you have any of the audio levels set to an extreme setting? They should all be set within mid-range. The application "power" slider, the soundcard levels and the K3S Line level are the ones of concern. Are you driving the K3S with sufficient audio. You should have 4 bars solid with the 5th bar flashing on the ALC meter. See my article on that subject at my website www.w3fpr.com for a full explanation about setting the audio levels for soundcard Data modes. 73, Don W3FPR On 2/9/2019 11:12 AM, William Liporace wrote: > I have a K3s (upgraded K3) and K3S (factory built). > Keying is being done with a MORTTY device.

Will,
I answered without reading carefully enough - most questions of that sort are about FT8. With RTTY through a soundcard, you should be using AFSK A mode. It defaults to LSB and my comments about DATA A mode otherwise apply. If you are keying the FSK pin in the ACC connector, then you can ignore the audio levels, but you do need to convert the level to TTL voltage levels (+5 volts and ground). If using that input, the K3 mode should be FSK D. 73, Don W3FPR --------------------------------------------------------------------------------------------------------------- Will, Are you using DATA A mode?
