I've been using my spare for several months, an intermittent problem on transmit with the spare that I couldn't fix had me reinstalling the 959, it works really good and the stock meter is easily readable, wish I had done it sooner, I put on an old but usable Fire-stick 2 at the same time, it gets out fine and I'm not cross-channeling.
I have it set at 4 watts out, too.
