What RF regime do bicycle computers and heart rate monitors use?
Previously, I owned a relatively expensive ($300) Polar S-710, which did not
appear to suffer from any interference in the year or so that I owned it.
The $45 Vetta RT 88 that I recently purchased and quickly returned was
severely impacted by electronic devices including personal computers and
cell phones. The latter caused a problem becuase I mount my cell phone to
my handlebar. When I called tech support, the representative said this is
a know issue. When I told him this behavior was never exhibited by my
Polar, the rep responded with "that is why it costs $300".
Other people have mentioned that it is these computers are affected by
underground electrical equipment. Here in Manhattan, they could be
referring to subway transformers, but I can't be certain.
As I understand, the Polar models are coded and the cheaper heart rate
monitors (and bicycle computers) are not. Any idea what the difference is?
