[net.ham-radio] Kenwood TR8400

wrc@whuts.UUCP (CLEGG) (10/25/85)

	Since a discussion has been started regarding the quality of
	ham rigs from Kenwood and Icom, I thought I would add my 
	findings on a brand new Kenwood TR8400 just out of the box.
	The first symtom was during transmit in the 10 watt position.
	Only about 5 of the 7 LED lights would come on and after a
	short time the last two would flicker and die away. I think
	this may have been due to a low voltage condition at the
	radio, but from the discussions about loose ground connections
	and circuit boards, I am not sure that this was the case.
	The open circuit voltage at the radio was 11.9 volts and
	the wires were about 14 gauge, so that will have to be more
	closely looked at.
		The more important problem, however, is with the receiver.
	I measured the receiver sensitivity as -87.9 dBm for 12 dB SINAD.
	That's approximately 9 microvolts. No wonder I couldn't hear
	anything !!!! I don't know what is causing the problem but
	if it is anything interesting I will post my findings.
