To the group,
It has been brought to my attention that my OHR 100a exhibits some
drifting of its frequency.
To check it out I turned on the radio and recorded its frequency and
then just kept an eye on it for quite a while.
Freq. Time.
10114.9 1:49pm
10115.9 2:01pm
10116.1 2:04pm
10116.4 2:09pm
10116.5 2:11pm
10116.6 2:15pm
10116.7 2:19pm
10116.9 2:35pm
10117.0 2:40pm
10117.1 2:50pm
10117.2 3:14pm
10117.3 3:25pm
10117.3 4:00pm
As you can see it finally settled down on its own. My question is this:
Should I just let it warm up each day or go ahead and use it and hope that
the heat generated by the use causes it to settle down sooner?
Another question might be, does the radio have an actual problem or is
this amount of drift normal?
Thanks in advance...
