Jim,
Yes, I understand that, but --- If the terminal window works, the K3
itself is capable of generating RTTY.
Still, try the K3 Utility Terminal window to help to isolate the problem.
If the Terminal window does not procuce RTTY code, then the problem is
in the K3 DSP. However, if the terminal generated RTTY works, next try
RTTY from the paddles (or if you cannot use the paddles well enough,
store a K3 memory and play that).
If both of those work, look carefully a whatever level conversion you
are using between the K3 FSK input and your RTTY generating interface.
Problems like this are usually solved in stages - verify what is working
as well as what is not working and you can more easily isolate to the
source of the problem.

Don, remember that the RTTY generated from the terminal window does not use
the FSK interface. I was reminded of this last week when trying to diagnose
a similar problem. (Which I have yet to solve, but will now have to wait
till I get home again) I was thinking that the problem was with my HB
interface, but I didn't have time to swap out the opto in the box for a new
one. Maybe I have the same problem. Won't be back till next Friday so that
will have to wait till I have some time off. I would just get a steady tone
using MMTTY/Writelog, but got transmitted & decoded RTTY using the terminal
mode. First thing I will do is put the scope to the FSK port to see if the
signal is getting that far. If so the problem is internal, if not then
probably the 2N35 is gone in the interface. Will post here once I find out
anything.

Rich,
What firmware version are you running? I have version 4.61 loaded and do
not see the problem.
I just tried it using the K3 Utility Terminal window, and listened to the
monitor with the K3 in TX TEST and heard (and decoded) the text sent.

I will try to explain as best as I can.
When I put my K3 into RTTY mode it does not TX FSK. I get a single tone
with no power out.
Until I go into the menu and switch from 45baud FSK to say 31baud PSK and
back to FSK?
I know this has been discussed before but I have not seen any fixes in the
newest versions of FW.
Is there a FW fix coming for this issue?
