NUE-PSK Modem adds RTTY Mode

Just over the reflector, news that RTTY has been added to the very interesting stand alone NUE-PSK Modem:

RTTY mode now fully supported in NUE-PSK Digital Modem!

W8NUE and I are very pleased to annouce that RTTY mode is now fully supported on the NUE-PSK Digital Modem!

Milt has been working like crazy this summer to complete support for the transmit portion of this mode, and in the last week or two we’ve been quite successful in testing it on the bench and on the air.

The website has been updated with the latest software version 2.10g supporting this new mode, as well as an RTTY App Note describing all the details for use and enjoyment. It’s in the form of a PDF (, and I’ve attached it in text form below here in this message.

I’ve also updated and simplified the wording that describes the multiple ways one can update the modem software. The mem.dat file and three .hex files are are directly accessible at the top of the Technical Resource section under “Latest Software” … just right-click on the desired file and “save as…” to your computer; then follow the standard directions on the page called “Loading the Latest Software” ( Many of you now have the optional USB card installed in the modem, making your update process just as simple as can be by just using the mem.dat file on your thumb drive. (Details on the USB card are at

We really hope you have fun using RTTY with your NUE-PSK Digital Modem. It’s a fun and time-tested mode that still has much of the old time operating “flavor” — long brag files, banners, and more — and now you too can play along, even while going portable with field operation! Be sure to let us in the NUE-PSK Yahoo Group know how it works out for you.
