I bought an MSR Reactor stove earlier this year and love it. I've got a question related to a problem that others may also have also:

When I fire up the stove and put the pot on it with water, initially it makes a really high pitched whine/whistle/vibration (almost like a microphone screech) for about 10 seconds. I'm not sure exactly what the sound is, but I've tried to hold the pot steady to stop any vibration and it doesn't seem to make a difference. Other than this I love the stove.

I use the stove to make hot chocolate/freeze dried meals in the deer stand, it is whisper quiet once it gets past this initial warm up, but it needs to be quiet "always".

Any ideas on how to stop the sound? It doesn't do it every single time, but almost.

Thank ya'll
