Priverstvuyu all on the forum! I apologize in advance for my bad Flyer yazyk.Ya ask you to help customize to your 950SDX.U me to this was the FT-2000 had excellent frequency response of the receiver and transmitter, problems with low frequencies are not bylo.Samoe bad that the FT-2000 Digital Audio (((((. Now I am doing a modification to the site-me kondensatory.Problema that's what I can not find the audio transformer and going to go with the audio in connector blocks PHONE IN.Dostatochno I will change capacitors with 0.1mkf 1 - 2mkf at the entrance of the cascade, or may need further upgrading of the input DATA stage? "Another problem, a different sound to the USB and LSB.Opornaya frequency is in place does not float, and the sound on the side USB-LSB different --- how you can align it? In the LSB it with a few Nazca frequencies, but wool is not transparent, and USB media, he is transparent, but there is no low chastot.Kak is correct? Scale ALC shows in SSB only enabled processor, but just an microphone pokazvaet do! "Why?" in FM does not show in the FSK --- shows how the scale should work? "I think that I cheated with this transceiver, I've read the positive reviews here about 950SDX and while I regret that he had sold his FT2000 . When in 2000 did not allow digital sound I have not sold, it does not need any soldering in 950SDX.No nonetheless I like kenvud.Pomogite I set my 950 SDX.73! :oops: :roll:

thanks for the reply, I fixed my 950.Guru's help me to remove the noise, which appears on the transfer by pressing PROC.(850 Kenwood such there is no noise!)I refused to feed the sound through the transformer and fall through the audio connector PHONE IN.Replaced by capacitors of 0.1 to 1 mF.

Howdy ua3lnk,
Welcome to the Forum!
So Sorry as we did not see your post.

The translation is very hard to understand in your post, but I will try to answer your questions...

To use 'PHONE IN' you will need to change C155 & C158 from .1uf and change to at least 1uf.

The USB and LSB sound I am a little confused on, was the difference in the TX Monitor or the actual TX Signal?

I will describe for the Monitor...
The Different sound from USB and LSB in the monitor is a result of the Sub Receiver XF1 on the RF Unit not being adjusted correctly. This Roofing filter must be adjusted for MAX flatness along with MAX Frequency coverage. If it is not then the USB and LSB will have different sounds because the filter is cutting it off and is not balanced.
Ref page 195 Item 4b of the Service Manual.

The ALC problem I believe that someone has mis-adjusted the ALC Power controls on the rig. The adjustment procedure is located on page 200 items 12-15 of the Service Manual.

It sounds like someone has put the 'Golden Screwdriver' inside the radio and have not aligned it properly.

Take Care,
Voodoo Guru
