Does the ARRL perform aging-simulation tests?
Many of us have experienced heat-fatigue and/or vibration
fatigue failures in poorly-soldered connections - especially
since the era/error of lead-free solder - not to mention
poor quality components that fail early - these experiences
are across a variety of Chinese-built products.
The concern is that a new-off-the-shelf device may appear
fine vis-a-vis RFI today and become a nuisance a month or a
year down the road.
Just curious ... David KD4E
