31. t to prevent ground currents from flowing to the common ground point by way of the signal cable If you use a microHAM keyer a good test is to remove the DB15 DB37 connector and USB cable from the keyer and measure the resistance from the shell of the DB15 DB37 to the shell of the USB cable There should be NO MORE than FIVE 5 Ohms and preferably less than TWO Ohms between them Note many PC manufacturers fail to provide an adequate connection between the shell of the USB connector and the PC case If this is the case a connection can be established by bridging a folded piece of aluminum foil between the shell of the USB connector and the PC case Power all your equipment from a single wall outlet The safety ground often exhibits excessive noise between power outlets sometimes often due to other equipment powered from the same branch circuit lt is always better to avoid this source of noise interference It is also a good idea to check the power distribution for loose connections reversed neutral ground open ground and other wiring problems Sometimes the USB cable can be a source of RF interference the cable might have inadequate shielding or the transceivers in PC might be improperly designed causing data flowing inside the cable to be reflected as a common mode current on the shield of the cable This common mode current can radiate a significant digital noise If this is the source of your problems it can be significantly reduce
