118 ~ 136 MHZ aviation band receiver kit High sensitive air radio DIY kit
Attention! Product is kit, buyers need to welding!
Dedicated to receive calls between planes and towers, with good performance
of the antenna (VHF yagi antenna), open within about 190 km in the biggest can
receive calls between various types of aircraft and tower, like friends please
note.
Has the following features:
1, high using band-pass filter, suite 3355, NE602 mixing, MC1350 into
