Yaesu FTDX10 has odd subcarrier on FT8

June 6, 2022 | Equipment | No Comments

While doing a lot of station work, moving antennas, updating cable runs, I’ve done a lot of antenna vector analysis, fixing grounds, removed a failed (defective?) AlphaDelta spark arrestor, and also listening to signal quality with my other HF Rig (Yaesu FT-991).

When checking 20m and 40m, I didn’t hear the clear, clean FT8 tone, but what sounds like an overwhelming hum. I recorded an example of this here.

Weird signal on FT8 20m & 40m bands.

Research into what this might be, continues. I’m considering shipping radio in for service, but don’t want to be without my rig for a month or so, and only find out nothing is wrong?

I’ve solicited opinion from other HAMs. Maybe I’ll find a solution that doesn’t involve shipping something to California.

FTDX-10 – setting up WSJT-X configuration for digital (eg. FT8)

October 14, 2021 | Articles, Equipment | No Comments

Out of the box, my FTDX-10 didn’t fully function with my existing WSJT-X setup I was using for the FT-991. Using some other videos as my guide, I’m re-configurating settings so they play nice with each other.

FTDX-10 SETTINGS:

FTDX-10 mode – set to DATA-U (data upper sideband):

Set the Attenuator, Preamp, Roof filter and AGC.

Changed the factory ‘REAR SELECT’, ‘RPORT GAIN’ and ‘RPTT SELECT’

Changed settings for ‘LCUT FREQ’, ‘LCUT SLOPE’, ‘HCUT FREQ’ and ‘DATA SHIFT (SSB)’ from factory as suggested by YTuber… he thought the default settings compromised signal quality, so I started with the same settings;

WSJT-X SETTINGS:

Opening the Settings dialog.

  • Set radio to ‘FTDX-10‘
  • Set serial port to your ‘Enhanced’ virtual port, mine is cu.SLAB_USBtoURAT
  • Set the baud rate to match the CAT Baud rate you set in FTDX-10 settings for me: 38400
  • Data Bits: Eight
  • Stop Bits: Two
  • Handshake: None (this was Hardware for my FT-991)
  • Force Control Lines: DTR: High RTS: High
  • PTT Method: CAT (this was RTS for my FT-991)
  • Mode: Data/Pkt (this was USB for my FT-991)
  • Split Operation: None (this was Rig for my FT-991 — I’ll probably set back to ‘Rig’ later)

Under the Audio settings… you’ll want to locate and select your USB Audio CODEC. This varies by platform.. this is on an older MacBook Pro with the Silicon Labs (SLAB) drivers installed.

Conclusion

These settings worked for me to get operational with WSJT-X on the FTDX-10.

FTDX10 – Trigger pulled, but did I beat the other buyers to the punch?

October 9, 2021 | Equipment | No Comments

I’ve been watching for a decent deal on an FTDX10 to replace my aging FT-991. I’ve seen a few deals come and go but none seemed ‘good enough’ for me to pull the trigger.


I watch the MTC (Main Trading Company) used list almost daily. This AM I was surprised to see an FTDX10 appear on the used equipment list. This AM I felt like I just couldn’t wait for a better deal. With electronics supplies tight due to chip shortages, who knows what might happen to the market when the holiday buying frenzy starts.

This is a decent savings over the current prices for the rig. BTW.. who’d pay THAT much, and from eBay no less? Crazy…

Others might have tossed this in their shopping cart too.. so.. we’ll see if my order was first, or if I’m going to be back on the hunt. Hopefully I get the confirmation e-mail soon.
