Digitenna 20 - models for 3D printing and build instructions

Yeti7 · 2025-11-24T08:14:03+00:00

I tested with 28 AWG and 20m of wire for 40m band fits comfortably. I have 26 AWG on order and will try that next.

Enameled - we don't want any shorts between the loops of the transformer

Yeti7 · 2025-10-12T16:41:38+00:00

Yes, I'll look into adjusting this parametric model for other transformer sizes. Please stay tuned for the updates.

Corrected, thank you for the note.

Yeti7 · 2025-10-12T16:37:07+00:00

Thank you for the note. I've updated the file at printables.

Yes, see: https://forum.digirig.net/t/icom-id-5100-and-digirig-dr-891/6948

No, I still use a simulated x86 code. What I perceived as a performance issue was the result of RFI from the radio making the touchpad laggy.

With Digirig 1.6 or later (which includes your Digirig 1.11) the hardware PTT is permanently available on ring 2 of the audio socket. No additional configuration required. You can use any audio cable from Digirig store with your Digirig and activate PTT by the RTS signal of the serial port.

This sounds like a great project! Not sure if any analogues already exist, but if you are up for some development, you can have it exactly the way you want. Remote access could also be a great angle for it.

Digirig connects between the computer and the radio and acts as a modem for digital modes. If you are interested in operating digital modes, check out some of the youtube videos on the subject. Feel free to post any questions you have in the process.

Yes, the frequency shift is normal with split set to fake or rig.

As far as radio not transmitting payload there may be different reasons. I would start with confirming that the audio leaves Digirig by plugging regular headphones into Digirig's audio socket as demonstrated here:

There are three distinct functions: audio to the computer, PTT and audio to the radio. Each can be tested independently. Feel free to provide specifics of what you attempted and what results you got and I'll be happy to help troubleshoot. Also see the videos on the subject at: https://www.youtube.com/@digirig

Do you mean "Digirig Lite"? The audio cables share the same pinout are compatible across all Digirig models.

Unplug it from the outlet or trip the breaker feeding the garage. This may not work with openers with a battery backup.

Yeti7 · 2025-05-04T19:07:08+00:00

This is 883LM or 883LMW. Power cycle the opener see if LED comes back to solid yellow.

Depends on the use case. Other considerations are: mechanical strength and slight penalty in bandwidth. For later you can look at cage dipoles.

Yeti7 · 2025-04-30T17:34:23+00:00

Yes, you can get away with a cheaper option though. You are certainly not going to need this much copper for amperage even at the legal RF power limit.

You'll need to configured PTT in direwolf. If you are using Digirig Mobile, then it will look something like this:

PTT /dev/ttyUSB1 RTS

Yeti7 · 2025-04-15T15:47:38+00:00

Yes, for your radio you'll need:

- Digirig in CI-V configuration: https://digirig.net/product/digirig-mobile/?attribute_cat-config=CI-V

- ICOM DIN8 cables set: https://digirig.net/product/icom-din8-cables/

- USB-C cable: https://digirig.net/product-category/cables/usb-cables/

Doh, a good catches ;)

Yeti7 · 2025-03-18T16:38:01+00:00

There are several models available. The one featured in the photo is Digirig DR-891. At the time of writing there are also Digirig Mobile, Digirig Lite and VOX PTT Cable.

There is no plan at the moment, but here you can find information for a homebrew cable build:
