Running FLdigi with the Yaesu FT-817
Radio Configuration
Set Radio for Digital Mode Operation (SSB-Based AFSK)
- Use a mDin6 cable without pin 6, Squelch connected (I wiggled pin 6 until it broke)
- Looking into the male mDin 6 connector with the key on top, its the upper right hand pin
- Verify this as it is easy to get it wrong
Setup "USER" defined digital mode
Please refer to your Yaesu manual "Digital Mode Operations (SSB-Based AFSK)"
Menu #24 DIG DISP: display shift
- 0 Hz
Menu #25 DIG MIC: AFSK drive level
- 61
Menu #26 DIG MODE: User defined digital mode
- USER-U
Menu #27 DIG SHIFT: transceiver passband response
- 0 Hz
RPi - ALSA Configuration
Run setalsa-ft817.sh which sets alsa config to the following:
Note that this sets AFOUT
PCM L:[-16.50dB] R:[-16.50dB] ADC Level L:[-2.00dB] R:[-2.00dB] LO Driver Gain L:[-6.00dB] R:[-6.00dB] IN1 L:[Off] R:[Off] IN2 L:[10 kOhm] R:[10 kOhm]
Run alsa-show.sh to verify
FLdigi Configuration
- There are some very good FLdigi instructions for the udrc here
- These instructions differ for the DRAWS HAT:
- FLdigi has already been downloaded & built on the DRAWS image
- DRAWS swapped the PTT gpio settings for left & right connector compared to UDRC II.
- Run FLdigi by using the main desktop menu (upper left corner of desktop) > Internet > Fldigi
- These instructions are for FLdigi controlling the PTT with the RPi GPIO
- RigCat or FlRig are not used.
Select Configure > Soundcard
- Select the Devices tab:
- Select PortAudio and deselect all others
- The following assumes that the internal RPi sound device is not enabled
- Select udrc: - (hw:0,0) for both Capture and Playback
Select Configure > Rig Control
Left Channel PTT gpio is BCM 12
Right Channel PTT gpio is BCM 23
Select Configure > Sound Card > Audio > Right Channel
- To select the Right Channel tab do the following:
- Check the reverse left/right channels checkbox for both Transmit & Receive
- To select the Left Channel do the following:
- Clear the reverse left/right channels checkbox
Select Op Mode
- ie for Olivia 8-250
- Op Mode > Olivia > OL 8-250
For FLdigi do NOT set Radio for Packet (1200/9600 bps FM) Operation
Running packet apps with the Yaesu FT-817
Radio Options
Set Radio for Packet 1200/9600 bps FM Operations
Please refer to your Yaesu manual "Packet 1200/9600 bps FM Operations"
Menu #39 (PKT MIC) allows adjusting drive level.
Menu #40 (PKT RATE) to select AFOUT(1200 bps) or DISCOUT (9600 bps)
Note different connections are used for 1200 & 9600 (AFOUT & DISCOUT)
If you are having trouble connecting due to insufficient or excessive drive from the TNC to the FT-817
- use Menu #39 (PKT MIC) to set the drive. for 1200/9600 BPS FM packet, Page 41
- Depends on DIG MODE setting: RTTY, PSK31-L or -U, USER-L or -U
- -L lower side band, -U upper side band
- use Menu #25 (Dig MIC) to adjust DATA input level for PSK, Page 22
Use some "test" protocol to send out test tones and adjust the deviation by rotating the DIAL knob, which will vary the data input level to the FT-817's modulator. Remember to press and hold in the F key for one second when adjustments are completed, so as to save the new setting for Menu #39
RPi
- ALSA settings
- Use IN1_L IN1_R for 9600 baud (DISCOUT)
- Use IN2_L IN2_R for 1200 baud or less (AFOUT)
