Yaesu FEP-4 EARPHONE

PoC (Push-to-Talk over Cellular) technology has long been available on the two way radio market, but it was the recent expansion of 4G cellular coverage and modern, „smart” transceivers with PTT buttons that put PoC into the focus of interest.

This radio appeared in the Wouxun product lineup early 2019, in Hungary however it only had its debut in March 2020.
With my experience gathered over the years, I am actually happy that this time I am not reviewing a brand new device. Why? Usually, when new devices are put to market, despite all the extensive testing, the firmware always has some room for polishing. A one year old radio on the other hand usually has a firmware version already updated and bugfixed, and you can do without hunting for patches, firmware update or cope with menus full of irritating small bugs. I believe, this one year has been worth the wait.

We are informing you about some news from SDR World: about SDRplay's series of webinars, and about lots of video reviews.

These micro computers are strong enough, no wonder radio hams make good use of them for DIY projects.
SDRplay have also compiled an image file with software needed for using your SDR. You just need to copy it to a Micro SD card and you can start listening on the radio bands.
