WA3WSJ: Kangaroo KX1!
Locked
 
|
Hello all,
Well I now have what's called a Kangaroo KX1! It hiked 2-miles up the mountain to Pulpit Rock on the AT. I setup my BW Vertical and my KX1. I then hit the tune buttons and NO POWER OUTPUT! I then put my KX1 under my shirt to warm it up. I waited about five minutes and hooked it up to my BW - full power output 4w! I had to do this every qso and make the qso short so I could keep my KX1 transmitting in the cold weather that was below freezing. So during the breaks, I was walking around with my KX1 tucked on my belly under my two shirts and two fleece jackets just like a Kangaroo thus the name "Kangaroo KX1." I will troubleshoot my KX1 soon with freeze mist. I plan to first put my KX1 tuner in the CAL mode to bypass it and see if the problem is in the tuner. If not then hit the transmitter with Freeze-Mist to find the bad component. 72, Ed,WA3WSJ _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Ed,
Before going too far with the Freeze-Mist treatment, try reflowing the soldering. I would suspect a solder joint that makes and breaks as the PC board changes size slightly with the temperature change. Especially check the toroid lead soldering. The soldering is much higher on my suspect list than any component. Does it receive even though it does not transmit? If that answer is yes, you can rule out the DDS and any of its associated components from the suspect list. 73, Don W3FPR > -----Original Message----- > From: [hidden email] > [mailto:[hidden email]]On Behalf Of Edward R.

Following up on Don's suggestions, put the KX1 in the 'fridge, and
check it for key down output once a minute. If there's a sudden drop in power, it's likely a solder connection. If it's a gradual drop, it's probably not a solder connection. I'd keep the batteries outside the fridge to eliminate them as the cause of your no output problem. If you don't see the problem, put the batteries in the fridge and repeat the test. Let us know what you find. 73 - ed, k9ew. > On 12/3/06, Don Wilhelm <[hidden email]> wrote: > > Ed, > > > > Before going too far with the Freeze-Mist treatment, try reflowing the > > soldering.
