Hi everyone,

I have a RA25 dual band radio laying around and want to use a digirig with it. What cable would I use.

Thanks in advance

This is Retevis RA25, correct?

Looks like RJ45 mic connector, possibly same as RT95 which fits AT-778 cable from store.

You can confirm by ringing pin 1 (GND) to the chassis.

Ringing the pin? I don’t understand. I am still really new to this part of radio.

Sorry for the use of the lingo. Ringing in this context refers to confirming the electrical continuity (contact) between the radio’s chassis (ground) and the pin on the mic connector. You can use a multimeter in the continuity or resistance mode for this.
