Cross-band repeater using a Kenwood TK-5710H and a TK-8360HU-K

[k1jak]

I believe that I have the PTT working correctly in each direction, but the audio is not working.

The Tk-5710h works with direwolf (GitHub - wb2osz/direwolf: Dire Wolf is a software "soundcard" AX.25 packet modem/TNC and APRS encoder/decoder. It can be used stand-alone to observe APRS traffic, as a tracker, digipeater, APRStt gateway, or Internet Gateway (IGate). For more information, look at the bottom 1/4 of this page and in https://github.com/wb2osz/direwolf/blob/dev/doc/README.md) using an AUDIO2RIG with the same DB25 connector. (We have a few trackers that we use with S&R and map into SARTrack Search and Rescue Management system )

This is how I have the radio wired:
TK-8360 DB15 Pin-7 COR PTT TK-5710 DB25-Pin 4
TK-8360 DB15 Pin-5 DI (Audio In) TK-5710 audio out Radio DB25-Pin 6
TK-8360 DB15 Pin-15 Ground TK-5710 DB25-Pin 25
TK-8360 DB15 Pin-4 DO (Audio Out) TK-5710 audio in Radio DB25-Pin 17
TK-8360 DB15 Pin-6 PTT TOR TK-5710H DB25-Pin 20

My guess is that I have a cable logic issue or a programming issue.

Any suggestions would be appreciated. I would be glad to test the suggested changes.

Which Audio? PTT or RX?

Which Audio? PTT or RX?

I have no audio from the TK-8360 to the TK-7510, and ultra-weak audio from the TK-7510 to the TK-8360 when the microphone sensitivity is set to high. (So low it might be that I think that I am hearing audio and may not be hearing anything).

A few errors here but the biggest problem is using DI/DO of the 8360 for voice audio. This really doesn't work unless you have additional interfaces added. DI/DO is for data communications.

I'd say the TK-8360 is the poorest choice to do this with. Do you have any other radios that would be easier to connect together? A TK-8180 is ideal.

DI may work on tx side, but instead if Do, I would use external speaker audio AND set volume level 1vpp or lower until transmitted audio on other radio sounds /looks right THEN unprogram the volume up/dwn buttons so it cant be changed accidently.
most KENWOODS can play together,some take more effort,and if one does not have proper test equipment, then its a toss up

This is what I needed. Thanks, I will order a TK-8180.

If it helps, my friend, I'll share this configuration of two Kenwood radios, TK8302-7302.
