[TenTec] [Orion] V1.373b5

[Toby Pennington]

Barry, I suggested this some time back,  and also suggested they make the
sweep to work like the one of the jupiter where it takes a snapshot picture
of the band.  This would also free up memory and processing power.  The
sweep would not have to be active all the time.

The sweep works better in Version 2.056.  However,  in general the rewrite
of version 2 leaves a lot to be desired in the operational characteristics
of many functions of the rig.

precipitated the extensive revision.  The primary issue wasunresolved
failures in time-sensitive, state-driven communicationsbetween the three
processors on the DSP/Logic board. Each DSPprocessor had its own
state-machine or command sequencer. The DSPprocessors also streamed data
between themselves. In addition, therewas a master state-machine that
managed the interaction betweenprocessors, T/R operation and the user
display. Any loss ofsynchronization between these various entities would
lead to anunrecoverable system error that could be cleared only by a
powercycle.          Correcting the state-machines was not an option because
ofthe second issue. The DSPs were completely FULL. No memory wasavailable to
implement any fix. The V1 DSP code didn't make efficientuse of the available
resources. The V1 SSB/CW receiver mimicked theFILTER method of SSB
demodulation instead of the more code-efficientWEAVER method.

but they also redesigned most of the functions of the radio that are
implemented in the DSP. V1.373b5 is very stable for me if I keep the
SpectrumDisplay off, don't poll the Orion for frequency data and use the
Voice Data Recorder sparingly. It also helpsnot to use the software NB or
Noise Reductio on the Subreceiver.I hope this helps with questions about
