...and noisy! Tested it personally. Not recommended.
Now usinghttps://www.universal-radio.com/catalog/hamps/4912.html So far,
so good.
Although little activity on 80 and 160m.
Thanks, Vytenis. I don't trust most recommendations of product types
that are often (almost always) noisy, simply because those making the
recommendations are so surrounded by high noise levels that they don't
notice the noise from the noisy product. And here in the US, the average
home has several dozen noise sources. We hear our own, and those of our
neighbors.
There is no enforcement of RF noise regulations by our government (FCC),
after that agency was gutted 40 years ago in the name of "small government.
There ARE good ways for us to do our own tests. They are listed in my
applications note on finding and killing RX noise.
