LF: Olivia 8 x 250 / psk31 / MFSK 8 503 CENTER BEACON - RUNNING NOW - 1615 HRS

["Graham" <g8fzk@g8fzk.fsnet.co.uk>]

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
