Re: ubitx is available for $109, there are a3 catches


Never heard of the reverse polarity diode-protected relay with +V supply delivered to radio via NC contact.  A simple and neat idea.

But... a relay is an electromechanical device, and the relay armature in a relay capable of passing over an amp as per the uBitx on transmit must take in the order of 5 to 10mS to move, so wouldn't it be possible that in those few milliseconds the reverse power  has enough time to take out solid state devices?
