Paul, If it's not the white wire Jeff described, it's the diodes (for forward & reflected) in the SWR bridge. Same thing happened to mine. The SWR bridge diodes were replaced and everything worked fine.

Hi Paul, Something might have shooken loose in shipment. There's a 2-pin female connector (which only has one wire going to it) that can fall off in shipment (happened to a friend of mine), and, if I recall correctly, he had the same symptoms. I'd recommend that you remove the top cover and look for loose wires or connectors. The 2-pin connector I'm thinking of usually has a single white wire attached to it, and it should be mounted on the SDR boards next to (and immediately to the right of) the large multi-pin connector which connects the SDR board stack to the PA. Make sure this connector is properly seated. Good luck! - Jeff, K6JCA -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Beckmann-wa0rse Sent: Friday, March 30, 2007 6:30 AM To: FlexRadio@flex-radio.biz Subject: [Flexradio] Continuing transmit strangeness in new setup I came home tonight and worked some more on this problem. I hooked up a Lucas Weinschel DC-8GHz dummy load (50W, checked good at 50.1 ohms) up to the HF PA BNC with a single male-male BNC and a female BNC-female N adapters, no coax, both adapters had been used before with success on other projects. Attempted to run the calibration routine on the PA. On 160 meters, it keyed down, then up, then increased the value in the 160 box, then repeated until it got to 98 something. It then stalled and I aborted and reset the values to those on the pink sheet supplied with the unit. I added ferrite cores to the parallel port cable on both ends to help rule out RFI possibilities. I checked the voltage on power down and it held steady around 12.76 from a no-load of 12.83V. I looked at the forward and reverse power on the multimeter during tune and, even though tune power was set to 10W in the setup form, I get 579 W in the meter. Something is definitely wrong. Could something have loosened up in shipment? I hate to have to ship this back. 73 --Paul, wa0rse _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ ________________________________________________________________________ AOL now offers free email to everyone.
