Exploring SDRPlay Receiver – Good Value

With Christmas approaching, consider exploring SDRPlay as you next radio adventure.

Using NodeMCU serial passthrough with a partner Arduino is a fast, simple and cheap way to overcome ESP-12E limitations.

Another great way to overcome limitations might be the NodeMCU Arduino Pro Mini combination.

You can add a GPIO expander to the NodeMCU for $2.

Although it’s powerful, the NodeMCU ESP8266-12 limitations can slow you down.

Using bias tee power injection is an easy way to send power to a remote device at the other end of a radio cable.

Yesterday, I converted my receiving loop from box to planar wound loop.

After designing and building, I have the receiving loop running, sort of.

My loop tuning board has been designed and built. And it even works!

Using NodeMCU remote control is a piece of cake.
