I haven't been using my iPhone & EasyDigi interface to do PSK-31 digital as much as I used to. Mostly, out of practice, but there was also a documentation issue. My little 3x5 card "field manual" didn't quite have everything on it, including some oh-by-the-ways/gotchas I used to know but have somehow forgotten, and some features I knew were there but was also out of practice of using. Too many after-findings scribbled in the margins. Also, some iPhone 4s-specific things like "take off that bulky case." Worst of all, there were no "now let's get back to voice" instructions, meaning that that procedure had to be reverse-engineered on the fly in the field every time. Doable, but another layer of unneeded complexity. So, I've spent the last week fiddling with the interface and the FT-817nd, and re-documenting things. (here's the original, now superseded documentation) Before this too gets lost in a miasma of half-remembered things, here's the new doc:
EasyDigi Setup; (done) = set once & forget
- PSKer: Gears > Always use built in speaker: Off (done)
- iPhone:
- Settings > PSKer > Mic: On (done)
- Phone Volume 4-5 bars
- Radio:
- Sp/Ph Switch --> Ph
- Volume/AF: all the way down, then slightly up; avoid overload
- VOX f-10A: On (only works with SSB, which we'll be using)
- VOX Delay #50: 100ms (done)
- VOX Gain #51: 35 (done)
- SSB Gain #46: 10 for digital (65 for voice)
- Set PWR to 2.5w
- Use V/M to get to correct memory to set frequency, then use < > to use USB mode.
- Adjust phone output, watching ALC meter while transmitting.
To Get Back to Voice Operations
- Sp/Ph --> Sp (unless using phones)
- VOX f-10A: Off
- SSB Gain #46: 65 for voice (10 for digital)
- Set PWR to 5w
- Use band, mode, volume, etc. per usual voice operations.
Also Useful:
- #38 Op Filter: CW/Off/SSB -- my '817 has a 500 Hz CW filter under the 'SSB' setting. YMMV.
Finally, the 3x5 card was replaced by a 4x6 Rite-in-Rain page. Slightly larger, much more robust.
This lightweight interface and a little plastic USB keyboard chops 3 out of 4 lbs off of pack weight relative to hauling out the laptop and SignaLink. (That's -6 dB in weight!) It's a little cramped for contest weekends, but all I really need for weekday trail afternoons on 20m. Don't forget the 3.5mm-to-Lightning dongle, the EasyDigi interface box needs it. I keep a dedicated dongle the same bag.
Rainy day. Read, nerd out, fiddle with gear. What else you gonna do?
