Mine did not work out of box.
$ wasted. WASTED!Very good product, must have if you are flying in metro parks to avoid interference.very nice product of great importance. for a long time i was wondering why i have so short range on one of my fields. now i know that there is a some radio station which i were fighting all these years!
This is a nice product. It allows you to set the band,channel,squelch,attenuation,warning speaker, and on time. Alarm sounds if a signal is present within the selected area around the center channel. This can be set to the entire band or just the selected channel. Just set your tx channel and sweep. The alarm tells you is there signal in the range. 4 stars because you don't know the channel of observed signals. Only the center channel is known.Vety good product. I wish the price is a bit lower.Great tool. handy for checking for freq. in use or any abnormalities on your frequency.So far so good I bought this to check out a site that I had recently started to get glitches. I use this not to warn me if any interference may accure
