Well  that's  true ,

Its a true live keyboard data mode , with no time locking or limits normal hardware requirement's , can be used as a beacon , but Opera is the better option for this (now)

there are 2 speeds mf-2 and mf-7 , mf-7 data rate is the same as psk31 , with s/n 10 or 12 dB lower , non linear pa and not affected by phase , mf-2 same s/n as wspr and about 8/9 dB lower than mf-7

Development , its really down to how long would stations wait for a 'qso' at the moment 2 baud is just about usable for a normal exchange , would 10x times longer be used ? with another 8/9 dB gain , say 10 db lower than wspr ?

...because nearly no one is using the mode and because there are already to many modes.
I don't even have a cat but the random numbers is an argument :-)
I should send some 15P6715P67WCV for Eddie. Many jobs to do...
Apart from the jokes, i hope that JT9 makes some new steps soon. If the timing becomes as less critical than in WSPR, it is very promising on LF/MF!

Why not send ros-mf-2 mode its the same s/n as wspr , linked to psk -reporter and can send ' the quick brown fox jumped over the lazey moon' ive two cats and a dog or anything you like : )) or some random numbers to cause confusion ):

(but needs   sdr  or  audio > rf translation)

Dear LF group,

In case someone is interested, i'm spending the night in WSPR (until 6 UTC) on 137.44 kHz.
