I use a cardio sport and a Timex HRM (not at the same time I might add). Now sometimes I can run for well over an hour with no problems. Other times I am less than a mile down the road before I start getting loss of signal. These clear up (mostly) and the monitor reports correctly my heartrate again. However I then get the monitor losing signal two or three times every 10 minutes. How can it work well for an hour or more with no signal loss one day and other times be a complete waste of time? Any advice on positioning of belt, what to moisten the belt with...etc would be appreciated. Oh I tend to soak my belt in a sink for a minute or so before the run.
