The receiver has undergone some servicing, due to PLL disengagement. This solved therev appears a new problem. When the USB is correct on the audio pitch the LSB is not. Where's the problem and how to solve this?

Re: R-600 with SSB problem
It is perplexing that only the alignment of the lower side band would be affected by the PLL repair/replacement. The output of the PLL/VCO is common to both the USB and LSB and the problem would be on both. In any case, what perhaps is required is alignment (internal tuning) of the LSB side. However, often, there would be multiple steps in performing said alignment (and in some cases, need for an RF with/and an audio signal generator). Having said that, perhaps your best bet would be to make use of the detailed procedures as outlined in a service manual. Unfortunately, they are not as readily available as user's manual (freeware). Some available (for a fee) may be found here, here, here or here. Pls confirm with the possible source contents to include detailed alignment procedure.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Sounds like a problem with the VCO / PLL Circuit since nothing happens in RX or TX. Check to make sure you have the correct supply voltages to start with and also check to see if you have 10.240Mhz. Use the service manual and go through the PLL/VCO alignment section. If anything is missing then you at least know where to look.
On the Satellit 750 you have a button marked SSB. If you have selected a shortwave band then you can press the SSB button. Pressing the button repeatedly will toggle between LSB and USB.
You will need to know the exact frequency and the broadcast time, and the side band. Turn the radio on. Select a frequency which you know carries SSB signal and wait. Those that broadcast on SSB are not radio stations, maybe ham radio operators.
You can also select a short wave band, press the SSB button once or twice to select the side band and launch the automatic tuning system. It will scan the meter band and stop for a few second when it receives a strong enough signal. If you are able to perceive a clear signal on LSB or USB then you found a broadcaster. Some radios just have SSB and you cannot choose the side. Personally, when I buy a radio I always insist on SSB but I have never been lucky tuning in an SSB signal. I keep trying once in while.
An FM modulator is a little box that plugs into your receiver antenna connection. It sends a low-level signal directly to the radio which you then tune in on the FM band just like a radio station. They're handy for older receivers that do not have AUX, USB, or iPod inputs. You plug your device into the modulator and it plays through the receiver. The "PLL" just means that the tuning uses a technology called "phased lock loop" which keeps the frequency from drifting.

Cure Replace X-tal (Viper) on SSB (item 1H00, order code: 2422 543 01397).
REMARKS: - Error 5: Viper does not boot. - Only a "reboot" is visible in the Debug menu. - Error will appear after heating up of the xtal.

It looks like you had some loose connections in that CB. you may want to also check for other cold solder joints throughout the units and touch them up with some solder. Might I suggest you use a desoldering tool and then just add new solder to the connection.
