Problem with the HK-T4A TX
 

Hi:

I have been using this radio system with no problems for months. The Hobbyking HK-T4A (v1).

Now, while I am sailing the boat, then it stops receiving signals. After turning on an off both the TX and RX several times, it runs fine again. Sometimes the problem returns after a few minutes, or it works fine for the rest of the day.

Sometimes the TX LED starts blinking, as if entering programming mode, but it still works (the RX receives the signals).

All of this started sine last week I tried to bind a friend's V2 receiver (with no success). Can it be the push button in the TX that turns on by its own having been internally damaged? Anyway it seems to be fine. This is really puzzling me.

Of course I measure both batteries (TX and RX) and they have their proper voltage level and charge.

I'd appreciate any help, hint, etc.
