Re: LF: My thoughts on ROS

John, LF,

I have set up Fldigi now to monitor your MFSK-4 frequency, I will post if anything seen/heard.

Using same rig & antenna as for ROS & WSPR.

Thanks for the informative write up of the history of ROS.

You've obviously delved a lot further into the mode than the rest of us.

For a one-man operation it's a remarkable achievement and I'll keep an
eye on it's future developement.

Perhaps I'm being hasty in announcing that I'll not use it again.

Let me know when you're doing more tests with it and I'll see if I can
persist!

In the meantime I've set up a repeating MFSK-4 mode beacon, using
"Fldigi" and it's running on 502.4 dial, with AF centre of 1kHz. It's
full daylight now, so I don't suspect anything will be received.

MFSK-4 uses some of the same techniques as ROS, but I don't know how
different the performance will be on MF.

Regards,

John
