One more thing... Steve when you see this, the software sends "CQ" (whatever you specify) in CMT Hell and then switches to the mode you have selected , e,g. PSK31, Olivia, MFSK32 , etc.

Steve is talking about what is often called "Video Text "  or " Video ID" sent in CMT Hell . A novel idea but a feature not often used these days because it is  rather slow compared to just sending plain text. Fldigi and Multipsk have the capability and both those applications work well with DX Lab Suite. DM780 also has this feature.  Use of this featured is discouraged  in digital nets.

There are some good things the ARRL does of course but sometimes I just don't understand why they do some things which makes it increasingly more difficult to support them each year.

Speaking to the bandwidth issue ... in 2006 (Docket WP 04-104), the FCC
extended the definition of "Data" to include a wide range of digital and
analog emissions *as long as the bandwidth was less than 500 Hz*. In
essence image is like CW now ... image can be used anywhere but it must
be less than 500 Hz outside the "phone" bands.

ARRL tried to shaft the CW and RTTY user back then and asked for 3 KHz
bandwidth for digital image outside the "phone" bands but the Commission
spanked them down in no uncertain terms.

The characters I saw were contained within the psk31 waterfall and in the same bandwidth. The remainder of the signal decoded with WinWarbler set for psk31. This technique was discussed 5 years ago on . I love DxSuite just as it is, and don't seek to add to anyone's burdens. Just thought you folks would have some fun with this. Many, many thanks again for the brilliant work you have already done and your extreme generosity in sharing the result.
