 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...
