[Elecraft] RE: K3 FSK RTTY - IT WORKS!

[Jim Talens]

Thanks to those who responded to my inquiry about getting the K3 to work on
FSK using MMTTY and a serial-USB converter.  I discovered one pilot error
and can offer one suggestion.

1. I did not see the little window called EXTFSK pop up because it was under
all the other windows.  Normally, a newly invoked window shows up atop the
others in XP.  This one did not.  I discovered it when I was shutting down
the computer one-window at a time.  Now I see it's plainly accessible by
left-clicking on MMTTY on the task bar.  MMTTY is one choice and the EXTFSK
is the other.  Once accessed, I selected COM8 (as I had in the MMTTY setup)
and then tried the various combinations of checked boxes until I found one
that worked [TXD for "FSK output" and RTS for "PTT output"].  So the
"problem" is resolved. 

2.  The serial-USB converter I bought yesterday at a local retailer works
fine for this purpose.  The MMTTY-specified Belkin converter is therefore
not the only one that works, which is good because it has not been sold for
a couple of years.  Perhaps newer serial-USB converters have evolved or been
changed, I have no idea.  The one I bought is an IOGEAR GU2C232A and I
suspect there are others that work as well. This one was $30.

Subject: K3 FSK RTTY

I am having a problem getting my K3 working on RTTY in the FSK mode using a
serial-to-USB converter.  Using MMTTY and not the Belkin (now unavailable)
converter, it just won't function, even with extfsk.dll installed.  However,
it does work fine using COM1 and a direct serial connection to the K3.  

When using COM8 and the serial-USB converter it does not work.

Most of the MMTTY information is somewhat outdated, perhaps, given the bulk
of information about it dates to 2005-2005.  

What are others using to get going on FSK using a serial-USB converter?

Thanks!
