Rf explorer is more portable and durable than software defined radio. My only concern is the battery charger and battery life. Thankfully, there is a battery menu page that provides percent charged and a large charging message.

Works great for looking at wifi channel congestion. If you do professional audio there are several 3rd party frequency coordination apps which talk to rf explorer. It's very easy to fry any spectrum analyzer if you hit it with too much power.

No sirve, la recepción está peor que con la antena casera que hice mientras me llegaba this pedido. It doesn't clean up the signal, it just makes a noisy, distorted signal louder. Not worth the money.
