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
