Lots of good Digital Radio content at the Microhams Digital
Conference. It's the weekend before DCC so if you're coming out to
the Pacific Northwest, come a little early and check this out.

WA,
In your MMTTY folder (the one that contains the file mmtty.exe),
is the file extfsk.dll present?
No.
n fact that file is nowhere to be found on the machine at all :-(
So guess I need to go back to your download page and find it.
Its all getting too complicated - the design was a request for
Tongue in cheek I hope :)
I do think this is the easiest way to go.

Which reminds me - where is all that datmode software that delivers I/Q
stereo outputs. Its only another line or two
I didn't intend on painting with a braod brush... I've had many great q's with
CO stations running perfect clean signals. It just seems that there are a
handful that I've seen which were the absolute worst looking/sounding signals
blanketing the bandpass with images. If I didn't know any
Hi Andy.
If you are up to something simple, reliable and useful, I have a proposal for a
PSK31 transmitter. With a VFO, fast XOR gate and a CW shaping circuit you may
generate a decent PSK31 signal. You just need a cheap controller to control the
XOR gate and CW on/off. I developed a simple

See attached, the image around 500 Hz is his MAIN signal with LOTS of
side bars, and the image around 1700 Hz is also him !
He had the trifecta:
1) sidebars around his main signal
2) second and third harmonic of his
What about adding some hum with harmonics??? Every 50hz a line . have seen
this from an Italian station
He had just forgot to switch of his processor in his rig . and a bit tooo

While the mode performs well over HF, the additional bandwidth doesn't
appear to have any throughput advantage over other modes that use less
spectrum. In fact, path simulations indicate that there is no difference
in throughput between ROS 500/16 and ROS 2250/16.

Andy,
You said:
FeldHell or whatever isn't an option. Its not on/off keyed - quite
intentionally - and FSK Hell needs more setting up than RTTY.
In it's simplest form Feld Hellschreiber IS on/off keyed! That's the way Rudolf
Hell did it back in 1929.
I seem to remember a dos program from
