Audio Problem at 52.525 FM

[k6biv]

Hello All:

I had a low "growl" when I was on 52.525Mhz in FM mode with a TS-480.

We did the "audio mode" and it is still there.

We soldered to the left part of the "cap" pad and the lower part of the resistor pad.

Tough to tell the proper place for the resistor pad??

Any ideas.

I also turned on the "Codec inp preamp" as suggested...

Thanks,

Tim

I had the same problem ( + distordet audio)

My solution with my ts-480 was to properly adjust the compressor ( if yours is activated)
It was doing more than needed and worked extremly on 6m - the rest was OK.
Taking the compressor a bit backwards and since its working like a charm.


Sorry for my bad english

Hello Felix:

Your English is OK..

I took the control head and the radio end of the RRC to the mountain yesterday. I used the Network for the connection and the audio was good.

My problem might be WiFi related. I use Tranzeo 5 Gig stuff. The path is about 10 miles and it is good.

I was not using compressor.

Thanks for your reply..

Tim


PS.. The audio is very good on Side Band..

Hello All:

It looks like RF is getting back into the RRC and creating a distortion in the audio.

Next time to the hill we will bring many ferrite's.

If I turn the power down to 30 watts the audio on FM is OK.. Back up, it is distorted.

I'm still not sure we did the audio mod correctly..

If I turn the "Codec inp preamp" OFF I still get audio.. Should this happen..
