Orion Model 565
General Description
High performance HF transceiver, analog + IF-DSP. Dual 32-bit ADI SHARC processors. Optimized amateur bands transceiver plus general coverage sub-receiver.
The Orion began production shipment in March 2003. The very first serial numbers were 09C10XX2, indicating September 2002 manufacture date. The Orion was gradually phased out in late 2005 as the Orion II began to ship.

- A review is available on the ARRL Members Only Web site
Operating Hints / Tips
- RF / AF Gain Operating Recommendation by KG6TT - a MUST read - (applies to v2 and v3 firmware)
- Hi Cut / Low Cut Explained by W4PA and John Henry
- RAM-CLEAR SEQUENCE: Hold Down VFOB LCK button at power-up. Added in Version 1.363
- MASTER RESET SEQUENCE: Hold Down MAIN RX/TX button in the ANT 1 column at power-up.
- MENUS-RX-PWR to access S-meter calibration menu
Orion SSB Transmit Audio Adjustment
RX-366 Subreceiver
- Signs that the RX-366 is installed:
- On power up, Orion screen displays "RX-366 Receiver Installed"
- With SUB RX button enabled, you can turn on PREAMP and ATTN
- In MENUS-Filtr, the bottom 3 displayed lines are Sub-Rx Slot 1-3
Common Issues
These rigs were manufactured 2002-2005 and the following issues are now often seen:
- LCD screen losing contrast and/or brightness
- Malfunctioning of encoder connectivity: RIT, MULTI, Tuning
- Electrolytic capacitors on A9 power distribution board need replacement
- Battery needs replacement
Mods / Adjustments / Repairs
- Orion s-meter scale adjustment - only works for firmware versions after 2.064x11 (thanks VE7TK)
- Orion V2 Sweep Mod - only needed if you use the sweep with v2 and v3 firmware
- TCXO Calibration Procedure by N6IE
- 28 MHz Noise Fix or Don't Use a "Y" Cable on the Accessory 12 volt Jack.
9MHz if output / Panadapter
- (click on above once and then again to see the beautiful panadapter provided by the Clifton Labs/VE7TK mod, LP-PAN and NaP3 software)
- 9 MHz IF Output Mod by VE7TK
- Configuring MicroHam USB Router to share Orion CAT port with NaP3
Note: The only truly acceptable 9MHz i.f. output is from the Clifton Labs/VE7TK mod. The 9MHz i.f. output from the RX366 subreceiver does NOT work well. Many late Orion II's were supplied by the factory with this output wired to the SPARE connector unfortunately.
LCD
- Orion 565 LCD saturation fix orion_lcd_current_reduction.pdf by PA1AP - mod at own risk -
- Orion 565 LCD replacement steps orion_lcd_replacement.pdf by PA1AP - use at own risk -
- Various LCD Replacement Displays by PA1AP - use at own risk -
RIT
- RIT-XIT Intermittent Encoder Fix (you should read this together with the next link)
- rit_cond_grease_fix.doc K4ZNO's Conductive Grease Fix (that actually works)
- Changing Out the RIT Encoder - but it's much more likely that it's not the encoder itself that's the problem - read the previous two links
POWER
- Power Distribution Board Capacitor Repair - Dark Screen, Panel Lamps Dim, No Receive, Spontaneous Reboots
Tuning Knob Trim Rings
Original and Optional 315 Trim Rings - optional rounded trim rings are MUCH more comfortable - purchase directly from Ten-Tec
