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)
