Joe, thanks for the follow up note... (I had to add confusion) but, I should mention that If do want to setup and transmit FSK internally to the K3/S AND you don't want to go the serial port route to control PTT and FSK off Serial port control lines. You could go with TinyFSK... which dedicates a single board computer to timing the Mark and Shift tones and PTT. So a couple years after the video you are watching now, I got around to making a TinyFSK Video <https://www.youtube.com/watch?v=cT5SfhUtTAw> which shows you how to use what is called a MORTTY Kit <https://hamprojects.info/mortty/> which makes using TinyFSK a breeze: https://www.youtube.com/watch?v=cT5SfhUtTAw All as I'm saying is, if you want to use internal FSK with your K3/S, you might want to consider buying a MORTTY kit if you don't want to use a serial port to control PTT and FSK mark/shift timing. So this video covers setting up MORTTY. Clearly, you can start off with AFSK and they venture into the FSK world later... or not...
What you have in the K3/S with the later firmware is the best rig available for creating the cleanest / narrowest / bandwidth friendly FSK signal. And if you invest the time into setting up FSK, you are immune from ever under driving or over driving an AFSK signal. Not to open up this big freaking can of worms and start a rhetorical holy war that has been fought over the years between the pros and cons of FSK and AFSK... but using FSK on a K3/S alleviates you from worrying about setting AFSK drive levels. I'm not saying AFSK is bad... (I'm sitting here with fear and trepidation that someone is going to go on a tirade now about AFSK being better than FSK... GROAN... please don't do it here on the Elecraft List). I prefer FSK on my K3S because I never need to worry about fiddling with the drive levels in a moments notice when some DX station comes on RTTY (which is rare these days anyway with the FT modes, sigh...). One less thing to worry about. If someone else loves AFSK and dreams about AFSK and eats and sleeps AFSK and talks about how wonderful it is with your XYL... knock your self out. It's nice to have options. A properly driven sound card based AFSK signal is great too. I don't argue or deny that at all. Anyway, have fun tinkering and deciding what you like based on your own research. Max NG7M On Fri, Mar 20, 2020 at 3:19 PM n9ok <[email protected]> wrote: > Thanks, Max.
