Hi Guys
The Net14/Net28 News for July 2010 has been uploaded to www.net14.org.uk . Not
a very exciting month with no contacts outside Europe reported for Net14 and
nothing at all for Net28.
But in the midst of preparing the report on 2nd August TU5KC-14, Didier in the
Ivory Coast, appeared on
Hi Tony, I have often switched from FH to FSK-Hell when working the
States from
VK via the Long-Path on 20M when conditions are poor.
Often switching to FSK was the only way to complete (or even initiate)
the QSO and the improvement in copy was often quite dramatic, from very

Thanks for pointing that out Dave.

A back-to-basics question for once...
Is there any modern RTTY datacomms software that gives a single wire digital
output for driving an FSK transmitter? Looked in the MultiPSK and MMTTY setup
menus and nothing.
While I realise there may be little call for such a one-wire drive now
Andy,
Can you be more specific about the design requirements?

A simple QRP Tx suitable for beginners, for example, is usually the ubiquitous
1 Watt 40m thing for CW that all the magazines and book seem include
ad-ad-naueam, built into sweet tins or whatever novel box they can think of.
I want to be different, and publish a design for RTTY. A simple
I think my FT-450 does that, just one pin on the CAT port, or the Data port,
where is my manual page 74.

I know that the old hamcom software does this .
In rtty and cw mode is sends the data 1:1 out on a serial pin on the rs 232
.
I know this exactly as I made a mod in my hamcom modem.
In rx the transistor is always set to high so I had to connect the ptt
transistor and the fsk transistor in

Just checed the help file of mmtty ''Prepare for FSK''
it uses the COM port to out put the FSK signal .. much the same as
CW-type uses the com port for cw tx via a transistor switch , or any of the
data software uses the CO port as a T/R switch .
I think 'delfi' has the
And hamcom modem is cheap
Just an opamp powerd from the rs232 .. Used as komparator
So you need no soundcard ...
What about using an si570 for the vfo?
And there is a lcd circuit for controlling the si570 .
That would give a nice cw psk rtty trx

side bars, and the image around 1700 Hz is also him !

It's NOT an attachment - it's an embedded link.
It looks pretty nasty too!
