TS-480 - dull (unclear) rx audio

[hb9rvs]

Hi
I have the RRC-1258MKII since about 1 year. I didn't use it because I had no remote place. Now I will have the possibility to test it for a limited time. I made yesterday the setup at my home qth (both rrc's connected to the same router). I updated the firmware and made the configuration according the manual. The system is running but...  the rx sounded very dull - not very clear. I changed the audio quality from 2 to 8 and 9. There was only a little improvement - it was not really good. I have no compare to decide how audio should be (with remoterig). There was a second point: I have the 500Hz and 270Hz cw filters installed. When I lower the bandwith the audio goes down. With about 300Hz bandwith I have no audio. When I lower the sidetone frequency I get audio - is this normal?
Thank you for your help.

Hi David,

TS-480 audio over Remoterig is excellent.
I mostly use audio setting #5.

Have you recently installed the filters?
Have you checked the audio response without Remoterig?

Hi

I agree with Paul it should not be any problem with the audio even if you use audio quality 0. So Your problem must be with the TS-480 itself

I had the same thing. It sounded as if you were listening to a station with strong flutter/aurora-like audio.
Never found what the problem was, but it got solved when I performed a full reset of the radio.
Did you try that?

Hi
The radio is ok. I normaly use it as a "normal" station - without any problems. The filters are since beginning installed. Another point: I have no audio in the speaker of the control unit. I plug the headphone in the RRC.... is this normal? Maybe the cable between control unit and RRC is not ok. I use the original cable on the rempte side.

I had a look on youtube. In the videos I saw there was a clean and good audio. I'll check my cables.

Was this strange sound in normal operating or remote?

Hi David,

Reading your remarks about lowering the sidetone pitch and reducing BW, it seems to me your audio is cut off above 500-600Hz or so.

Maybe there is a capacitve short to ground somewhere.

As temporary test you could use simple standard RJ12 6p cables, so you could check if one of the Kenwood 6p cables is broken. Like these:

Note that these RJ12 cables are unshielded, so just use them for testing!

The control head should have good audio from speaker and headphone output.

BTW is audio dull on every mode?

Ok - problem is solved!
The cable was definitly a problem - audio is now on the speaker. The dull sound was an other point: IF-Shift was activated. I suppose I activated it unseen. Now all is ok - the sound in normal and remote operating is the same and sounds good!
Thanks for your help.

Good to hear David,

Murphy's law.
There is always a second error helping the confusion ;-)

Enjoy the combo.
