View Full Version : TS-430 Microphone wiring question
11-04-2009, 03:15 AM
I have a Signalink USB on the way, and don't want to have to use the microphone cable and a speaker cable on my TS-430 since there is no receive audio in the microphone connector.
My thought is to pipe audio in to the same pin (6) on the mic connector as the newer Kenwood radios. Anyone else tried this? Any idea where in the rig I could grab the audio? I checked my TS-241 and the audio is a fixed level, so I figure that's what I should try to emulate.
I looked at my 430 service manual, and it shows that there is cuurently no connection to pin 6, so I think it's a viable option.:D

Doesn't the TS-430 have a ACC jack on the back? If it does, that is where I would wire the SignaLink to.

It has 2 jacks on the back, but neither appears to have a microphone input in it. One is for the AT-250 tuner, the other is for attaching an amplifier.
I guess I could use pin 1 of the 7 pin amplifier connector, as it does have speaker output on it. But then I'm stuck with 2 cables, which I don't want.:p

The thing about the 430 is. If you have two audio lines going in to the radio. Each one will bring the audio down. the radio is set to work with a 500om mike. the other audio line will take 1/2 of that. You will need to be able to brake the audio like that you are not using at that time. What I did was put a stereo jack and put it in my mike with a switch that will switch the audio line from the mike to the interface. It works good.

this may be responding way to late but I just saw the post and thought Id throw my 2 cents in.
Look on page 22 of the operators manual and read the part about the using the Phone Patch. this may give you the audio input you need on the unused pin of the remote connector without seriosly effecting the input levels on the mic connector. I believe this will give a line level input rather than mike level.
quote from manual
" use a 100k resistor in series with a 10k resistor to ground on the input side of the 100k resistor use shielded line and connect as follows.
on the IF unit X48-1370-00 install the fixed divider at the junction of r161 10, c94 100pf, and c93 1mf (input of Q34). add an RCA jack at the empty rear pannel opening or use remote pins 7 and GND for input."
I found the description confusing but here is what I did
If using the remote connector solder a 10k resistor from pin 7 to ground. solder one end of the 100k resistor to to pin 7 then run a shielded line from the point described above on the IF board to the 100k resistor and solder the shield to ground at the remote connector and at pin 2 of connector 8 this is the ground for the mic connector. this is best done of course on the solder side of the if board this should give you a line level input to the transmitter.
Ive done the work but have not tried it yet. I am trying to use a small mixing console to feed inputs to the rig offering a choice of mics and or computer inputs to this and other rigs. I haven't tried it yet but this is the mod I will be using on the TS430s for this project. hope it may work for you.
