Coming Soon in Release 1.370

In an effort to keep you better informed we want you to know what Ten-Tec is working on for the Orion transceiver.

The Orion Beta testers are testing the following modifications that should appear in the next release.

We are still working on a few items and hope to have this out very soon.

- Added band line update routine to the serial frequency set command.

- Modified VFOA/VFOB tuning to use the Step of the associated receiver, as per the manual.

- Extended 60m band lower edge to 5.255 to catch the UK special privilege assignment.

- Modified A>B B>A code to prevent changes of mode if no receiver assigned to the source VFO.

- Modified main encoder routines to disable FAST encoder rate when in MENU mode.

- Decreased programmed-delays in SWEEP system to improve update rate.

- Modified PBT/BW and HI/LO Knob routines to prevent changes to those settings while in transmit.

- Modified AF Gain relationship to MAIN and SUB controls to fix MAIN/SUB conflict with LEFT OUT when

Headphones were not being used.

- Modified POD encoder settings to group PBT/BW together.

- Additional Modification to ALC system. Changed CW transmit gain adjustment routines to prevent adjustments during attack and decay


- Moved sub-receiver meter routine from interrupt routine to main loop. This was causing greater than expected CW variation when the

KEY/PTT occurred during this routine.

- Reallocated time slices in the sweep routine to prevent conflict with DSP TX transition routines that are suspected of causing loss of transmit


- Corrected code that sets external band data. Conflicting calls to this routine during Interrupts caused the band data to be in error when set

from the serial port.

- Modified QSK hang system to eliminate hangs impact on CW timing

- Modified CW T/R and R/T timing routines to improve accuracy of keying.

- Modified serial CW send feature to add standard delays to characters and words.

- Doubled RIT encoder's FAST rate.

- Modified Tuner control to eliminate false initiation of tune sequence following band changes.

- Modified HI/LO routine to properly handle FSK mode.

- Modified CW Dynamics system to allow full range control on external keyer, PTT and AUX PTT ports.

- Added keying speed Warning message for >5ms dynamics setting.

- Added MOX control and supporting menu selection.

- Added NONE option to rear PTT input action.

- Changed QSK hang routine to take into account modified QSK hang method in build 8.
