You’ll need to homebrew an audio/PTT cable. Optionally, if you also want CAT control, you’ll need to make sure that Digirig is in RS-232 configuration and add a crossover DB9 cable. I have those in stock, but they’re different from the regular DB9 cables so leave me a note if you want that variant.
You’ll also need a 2K resistor, not just short between ring 1 and ring 2 on TRRS side.
As for RS-232 cable - you only need it if you prefer to add optional CAT control. I’ll be able to ship it after my return from the break at the end of the month. Please make sure to leave a note or message me the order ID.
How would the easiest way be to build it?
Get a cable similar to the one I’ve included, a TRS, and then another TRRS with the 4 wires, and have a small block in the middle to put the connecting wires and resistor similar to how some cables like the yaesu scu58 is?
So I got the cable ordered, and the audio cable made. Two questions now.
I saw that the digirig needs to be put in rs232 mode by soldering the spot on the board, is that the only way?
And if so, will that make it so that I can’t use cat control on something that doesn’t use rs232?
And I’m not home to check my settings for the radio, but hopefully what I can provide is enough to get an idea.
The home brew cable I made kind of works.
I tried it with wsjtx, and it’ll decode.
When it tries to transmit, it’ll rapidly click but never transmit that I can tell.
I got the cable made and tested with a multimeter to make sure it’s wires line up right. Does the gauge of wire that I use matter?I think it was 26
