FINALLY!!!
Someone's got of deir Lazy Keester and put some Info 'bout the SDX on-line!!
All's we can say is...'bout time.
There's links on this page to various SDX Modifications that we've performed.
Inside these Modification Pages will be Instructions, Pictures, SpectraLab graphs, and Recordings that detail the modification procedures, and show the results from them.
If you would like Voodoo-LABS to perform these mods
or if you would like to purchase a unit already modded by us,
then check out our Price List or give us an email.
We've always wanted a TS-950sdx. It's a beautiful rig, the pertiest that Kenwood's ever made. They actually made this rig as the Flagship for contesting. That's one reason it has such selectivity. It comes from the factory with 500cps filters installed in both the 8.83Mc and 455Kc IF's.
One of the things that always floored us was the lack of modifications on the internet for it. There's hardly anything on the web about it. We'd plans on getting one, so a service manual was purchased and the schematics review was started. We do this on all the rigs that are about to become part of the Voodoo Studio.
Can't have a rig here with poor Frequency Response....aighnt NOOOOO Way!
The schematics were reviewed intensively for about 8 months and a plan as created. Once the right TS-950sdx victim was abducted for X-treme Audio Experimentation, It was Defiled with Extreme Prejudice.
These are the results of our vicious carnage.

These are the Receiver Mods for the TS-950sdx. They consist of complete mods for the Main Receiver, the Sub Receiver, and the Monitor Circuit. It'll give you a flat Audio Frequency Response on the receiver from around 25cps to 6Kc. This is on both the Acc2 and the Headphone audio outputs.
The Monitor is very close to the true transmitted audio response. There are a few anomalies with it, but we're working on them.
These are the Xmitter Mods for the TS-950sdx. They consist of installing a Jensen Audio Xformer into the sdx, installing a Mini XLR in the back of the sdx, and modding the circuitry to allow the Line audio injection into the DSP. This is done in a way to allow the Mic Gain, VOX, and Processor to still function. The TX Frequency Response is greatly improved.
These are the IF Filter Mods for the TS-950sdx. They consist of adding a jumper or a wider filter to increase the maximum 6Kc bandwidth of the 455Kc IF, Changing the 10.695Mc IF Filter in the Sub Receiver, and "Tweaking" the 12KC LC Coil in the 8.83Mc If.
These are the AM Mods for the TS-950sdx. There is a mod to the circuitry to get the missing Low End and High End Frequency Response, and an In-Depth circuitry change mod to get rid of the High and Low Frequency distortion while getting better Fidelity.
This is a Mod to delay the Audio from coming online immediately on power up. When the rig is turned on, there is a 4 second delay before the Audio will be engaged to the speaker outputs to keep the Pops/Clicks from the Power Supply Rails charging up, making it to the speakers. When turned off, they drop the outputs immediately.
