if you are riding with others, you could be picking up
two signals.

A lot of times a dry or loose chest strap can cause
false readings like
this as well. Most people seem to lick or spit on
their straps before
putting them on. There are special creams made for
this purpose, but
spit is free.
Wind/descending can also screw them up. Recently I
was coming down a
hill and the zipper on my vest was hitting the strap
causing the reading
to spike.
Of course, the batteries do wear out after a while.
I'm not sure if a
low battery would cause incorrect readings like
this. If it is the
battery in the strap though, I think the only option
is to replace the
strap.

Hi David,
These HRM's can give odd readings for various
reasons other than the
battery. Proximity to overhead high voltage lines
is common as well as
being near fields of high radio energy such as
around the west hills of
Portland. Known hot spots for me are Germantown
road about a quarter
mile up from the lower junction of Old Germantown,
Skyline east of the
Cornell intersection. I also see oddities in SW
Portland in the area of
Multnomah Village and the Garden Home area. Some
days are error free
and other days are the pits. Weather conditions such
as cloud elevation
has been known to factor into the picture as well.
Portland is unique with the west hills and all the
TV, FM, AM broadcast
stations as well as a multitude of Common Carrier
services. As an
example if one takes a commercial grade TV camera
(typical of TV
stations) up into the west hills the color will
shift due to all the
radio (RF) energy in the air.
I see heart rates around 227 that hold steady and
then jump down to what
I really am doing.
Hope that helps you as well as other readers of this
forum.
