Thanks Hung, me too! Surprised and a bit disappointed, but taking it in stride because I had anticipated such events with a spare radio, so I won't lose any flying over it.
I also ALWAYS fly with a hand-held radio in case I lose ALL electrics (happened to me before and the hand-held saved me).
I am in a region where having two radios is almost required...I really feel a bit underprepared to fly without two working radios here.
So, I will simply send it back ($42 shipping) and see what we can do...in this hobby, throwing enough time and money (and seeking good advice HERE) at problems can usually fix them! Crazy what we all do...
I have not given up on my process of keeping three OLDER radios going - it is what fits into my budget and flying profiles. So, patience in all things...easier to SAY than DO, but we are dealing with OLD stuff. I am sure that radio is at least 25-30 years old? How could I tell when a radio was manufactured? It would be interesting to know...
