"@HamidHamoun84 Exactly. I checked my own RF instruments. All are American German and Japanese (e.g. Signal Hound Anritsu Agilent/Keysight R&S etc) I won't buy a Chinese spectrum analyzer or RF power meter as my main device (yet)"

"If you could revive a discontinued RF/electronics tool what would you choose Here's one of my candidates: EraSynth Micro a portable RF signal generator with great performance and features for its price point. No good alternative exists for it"

"This is the first serious RF measurement tool I got X years ago. It's a portable RF lab: spectrum analyzer signal generator RF power meter and VNA all in one device. I don't use it much now since I have better tools but it was a step up from the hobbyist tools I had before"

"Growing up in Iran in the 90s Mehran Kit ( ) was the highest quality (and most expensive) electronics kit manufacturer mainly targeted at teenagers. I couldn't afford their products back then (was buying cheaper ones or making my own PCBs manually) X years ago I was informed by a friend that they're closing their kit business so I asked him to buy and send me a few just for the nostalgia. Left to right: LED star wireless mic FM transmitter. A reminiscence of the good old analog days"
