TK-5710-K - 3.5MM

[vraho10]

I plan to use the TK-5710-K for streaming, but I'm seeking guidance on connecting a 3.5mm male cable to the radio. Based on my research, it appears that utilizing the 9 Pin ACC is the appropriate method.

The connection process is as follows:

• Connect the Tip (left audio) to either ES1 or ES2 (BTL output for external speaker A).
• Connect the Ring (right audio) to the other pin between ES1 and/or ES2.
• Ground the Sleeve to pin 9 (E - GND).

The radio's output is expected to be 8 ohms. To interface it with a computer or USB sound card, I recognize the importance of matching the ohm resistance for optimal performance, such as with the sound card and would include the appropriate resistor to best match the USB soundcard.

Would this be possible and work, or am I wasting my time?

That's a speaker level output and will likely damage your computer/sound card. It's also a BTL amplifier, and you have to be very careful how you utilize it, or you'll break the audio amplifier.

Using the DB-25 on the rear of the RF deck, you'd be better off using Pin 8, "RX audio signal output" and pin 10 for ground.
Pin 8 is 1KΩ impedance with a 0.65v peak to peak voltage, which will be better suited for what you are doing.

Thank you, I will try that.
