No  problem Dave,

Sorry Graham,

I only listened for Olivia - I've not tried multiPSK MFSK yet. I've got a
screenshot of the waterfall display showing the Olivia signal received here,
along with the other stations. I'll send it direct- too big for the
reflector!

Dave,

Thanks for that , That is close to the full beacon text .. did you take any
of the mfsk ?

Tnx- G ..

Follow on from last night , As the olivia system transmits tones in
parallel
it requires a linear system,   however , MFSK is a single tone phase
continuous  system , I am using   three applications of  multipsk running
on
the same pc in beacon mode

8 tones are selected on the two modes  psk31 is added as a reference
signal
and is not expected to  print as reliably

All  3 modes are the same peak power level , set at the agc threshold ..
about 10 watts per system at the moment . there may be a small change in
level as each mode starts and stops , the differing beacon lengths' are
resulting in the tx windows slowly shuffling.

Note , the station is in continuous  TX due to  vox audio  drive levels
producing alc preventing the power levels to  be normalised

Running  3 mode beacon

Dial set   502 khz usb

1000 hz  center   olivia  8 x 250 hz

1250 hz   psk31

1500 hz  MFSK  8

Reports  welcome
