Hey all, I'm having troubles with my PT SL. It suffers from constant dropouts in the cold. I never have problems with it in warm weather. Previously I was pretty pleased with my purchase, but now I'm ticked that I bought the SL and sold my Pro. The Pro always worked for me. Attached is the resulting ride image from today. You will notice 3400 watt spikes, TONS of data dropout, etc. etc. etc. It was just barely above freezing today. Much colder and it doesn't work at all. Thoughts? Stick a heating unit to my SL?
