<DIV><FONT face=Arial size=2>Good evening to the group,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is there anybody out there who would be kind enough
to help me to choose the correct settings for RTTY. I get lost trying to
configure MMTTY, microKEYER/USB-Device Router, WinTest and the IC-7800 with the
intent to copy and transmit clean FSK (not AFSK).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>By far the best reception of FSK is by means of the
built-in Decoder of the IC-7800. There is also no problem at all to transmit
clean FSK by using the IC-7800 as a stand alone Radio with a keyboard connected
to it. Although this setup works perfectly alright for random QSOs it is of
course a hopeless proposition if one wants to take part in an RTTY contest: No
auto-numbering, no logging, no comfort at all.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The best I could achieve so far - using the
combination of WinTest V 3.14, USB Device Router V. 4.0.10, and an unknown
version of MMTTY (app. 2 years old) - is the following</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(a) RTTY-reception clearly worse than with the
built in decoder of the IC-7800, i.e. I need stronger signals with less
qrm/qrn to read a clear message</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(b) if I press the F1-key for CQ for the first
time, the radio seems to send the correct CQ-message. If I press it thereafter a
second or third time I only hear diddles with an occasional burst of RTTY-info.
The same is true for all other F-keys: First time they seem to perform ok,
thereafter only diddles with occasional bursts of RTTY.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>All of this has nothing to do with RFI: Even when
outputting 5W only I still get the very same results.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Since I would like to participate at least for some
hours in the forthcoming CQ WWDX RTTY contest I wonder whether there is anybody
out there with a similar setup, who would be willing to share with me his
MMTTY-, WinTest- and microKeyer/USB-Device-Router settings for perfect
RTTY.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I know that I could deal with the subject by
changing over to AFSK. That worked ok for me about a year ago - but only in very
low qrm-level environments, i.e. not in contests. In other words I would like to
make use of the excellent selectivity of the IC-7800 by using FSK rather than
AFSK.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance for any help, which is much
appreciated. </FONT></DIV>
