Some people have reported that the LS10 'drifts'.
It could be possible that these 'pops' could
be as a result of this?
Just a thought as I have had problems
with digital gear where if the clocking isn't
accurate enough you get 'pops' and 'clicks'
as a result.

Let's hope it is the remote that causes them!

Following up on this, I have had a few emails with Olympus support 
and I have even let them have some files to look at. They say that 
the recorder needs to go back for repair. Well to be honest I don't 
think so, seeing as there are a number of people having the same 
problem.

Now a thought has just occurred to me: I am thinking that the problem 
is one of the processor being interrupted while recording, but as 
this is a dedicated machine, how can it be interrupted. Then it came 
to me... I am sure that in the cases where I have had the pops, the 
IR remote has been connected. Not necessarily been in use, but 
plugged in. Perhaps the recorder is getting signals from that causing 
the glitch?

A long shot I know, but I want to ask all of you that have 
experienced these pops, did you also have the remote plugged in at 
the time?

I am going to use the recorder with the remote taken off to see if 
that stops the pops.

If this is not the case, or even if it is, I urge everyone to contact 
support giving as much detail about the problem as you can. If we 
don't tell them, they are not going to do anything about it. This is 
a dammed fine recorder, and I really want to be able to use it 
reliably. The people here on this forum are more likely to spot these 
pops as we tend to record rather quiet scenes. Someone recording a 
band at a concert will not notice anything!!!

Thanks,

Mike
