[Premium-Rx] A TRUBLE OF WJ8178

[Mark Donaldson]

Bule,
 
Checked the archives on the premiium receiver web site, I described this problem and the cure for it in an email I sent out a while back. Some 8718s have this problem and some don't, it is caused by digital noise being induced into the head phone wiring and can be cured by a simple bypass cap. I am in Taiwan right now and am probably the closest list member and WJ8718 owner to you distance wise, wish I could hop on a plane and fly over there to help you out, also wouldn't mind picking up one of the Chinese military HF RXs I have seen on the Web. If you have trouble finding my email in the archives I will be back to the US next week where I can check my documentation and give you better info.
 
Terry O,
 
If that 8718 manual you have sounds like it is better than the POS Fair Radio manual how about doing the group a favor and run off some more copies like you did with the 8718 supplement manual you made last year, I will be first in line to buy a copy.
 
Regards,
 
Mark Donaldson

	Dear OMs:
	        I got a WJ8718A but it has some problem,does anyone could help me?
	the problem is: when i turn off the PHONE LEVEL I can hear some
	continuous noise like "hen...hen...hen"(low frequence audio) from
	 headphone(sony MDR-7506) and another continuous noise like "en..en...en..."
	(high frequence audio) ONLY come from the right ear if I turn off RF GAIN
	and turn on the PHONE LEVEL.that noise come from the powersupply in the
	receiver? or there is something wrong in the AUDIO-AMP part? Can you copy
	 the schematic of AUDIOAMP for me,and tell me which board in the case is AUDIO-AMP PART?
