I will be using this mainly for marine purposes. My requirements are VHF communications, GPS coordinates for emergencies and 121.5monitoring for emergency beacons. Water resistance , is, of course, essential.and I am a search andrescue volunteer. I comparE this to the UV9R pro V2which does not have GPS or 121.5 receive. I like A1
Surprisingly, retevis actually produced this simulator with GPS function. To be honest, it is very practical. Compared with the price of RT3S, a digital machine, A1 is very suitable for my wife and I to go hiking and camping. The introduction said that A1 can also receive aviation frequency bands. I will try it if I have the opportunity. I like the A1 very much.
