It appears to be fixed and in repairing it, I fixed another annoying problem, which was spurs and floaters on ten meters only. Those had been plaguing me for several years. First, thanks to Paul at T
I'm glad you found the fix. Why is it there are so many re-solder fixes these days. I don't recall ever hearing about resoldering on the old gear. Anybody ever have to fix a 75A4 or SX101, etc. by re

I'm surprised by having to re-solder these boards also Jim. I would have thought that a bad connection would show up much sooner. The first time I ran into it was on this same Omni 6 Plus which was a
I had a 961 power supply crap out on me, right in the middle of a contest. It was nearly 10 years old. The problem was missing solder on one of the connections in the power supply. It had simply neve
Back in the late 1970s and early 1980s, I worked on Motorola IMTS synthesized car phone radios. This was before plated through holes in PC boards were reliable. So, the Big M used eyelets, instead. T
Welcome to the lead-free world of RoHS. Your spools of 60/40 solder are NOT RoHS-compliant...but will likely improve reliability of solder connections which are subjected to the stresses of expansion
So the new radios have a built in failure mode that the "boat anchors" did not? That's unnerving? 73 de W6OGC Jim Allen Sent from my iPad _______________________________________________ TenTec mailin

I remember the older car radios (AM days) that M made. Same thing there. We had toexchange the boards under warranty. Clayton N4EV From: Steve Berg <wa9jml@frontier.com> To: Discussion of Ten-Tec E
QSL. In my former life in military and space electronics, I spent many hundreds of hours chasing RoHS-induced problems (today they're called "issues"), including the microscopic fracturing of solder
Artists have exemptions. I had a gallon of lead-based paint to prepare canvas, while a student at the San Francisco Art Institute in California. Maybe we could be artists? Connie w7cjd ______________

Your comments were very eye-opening for me Allen. I had no idea that RoHS compliance has such a down side. Is it the lead-free solder that's causing the problem? Later, Joe, K8MP <div> Sent from AOL

In my experience, yes. There are or have been a number of lead-free alloys developed to try to mitigate the problems arising from loss of the ductility properties of lead alloys. It's also true that
That's a question that TT should be able to answer. The RoHS Directive was officially put into force in late 2002 or early 2003. But, some (many?) manufacturers were made aware of the impending/propo
