 RF Cafe visitor Tommy Reed sent me this link
to a blog he recently posted on FromDCtoDaylight.com (great name) website entitled,
"17 Best RTL-SDR Software Defined Radio Dongles." About six months
ago I bought the Nooelec NESDR Smart v4 bundle to use with a modification I'm making
to a couple vintage 72/75 MHz radio control systems. The 3rd-party interface
and processing software is OK, but could be better. Otherwise, it works quite well.
Says Tommy: "Software Defined Radios (SDRs) are become more and more popular. This
is partially due to the wide availability of low cost USB dongle SDR radios based
on RTL2832U demodulator chipset. This is where the 'RTL' in RTL-SDR comes from.
While these low cost SDRs are not as capable as some of the higher performance SDR
radios, they do offer a good bang for the buck. In this post we'll take a look at
17 great RTL-SDR dongles..."

 Axiom Test Equipment, an electronic test
equipment rental and sales company has published a new blog post entitled "Setting up a Home Test System," that discusses the most important
equipment you will need when creating your home's test studio either for hobby endeavors
or for the need to outfit a work-from-home environment due COVID-19 conditions.
Cost of equipment is a significant factor when building your home test studio. However,
keeping costs reasonable is possible by either renting equipment or purchasing quality
used equipment at a fraction of the price which can be found through Axiom's extensive
inventory. Setting up a Home Test System Social distancing has become a new way
of life due to the COVID-19 pandemic and efforts to prevent the spread of the coronavirus.
Instead of daily trips to a test lab or electronic manufacturing facility, many
engineers are being asked to work remotely to minimize contact with others and the
potential spread of the virus. For many, home is the new office and workplace and
for electronic circuit designers, testing is a helpful if not essential part of
working on electronic designs at home...
