Hi, everyone.

 

Well, I got my new Astron RS35 metered linear power supply yesterday, and
set it up tonight here in my home shack.

 

Everything seems to work well, in that I get the output power readings I
would expect on resonant HF frequencies via my TS590, and on VHF/UHF
frequencies via my TMV71A.

 

I have noticed something, though, that I could use some input on.

 

For some reason, this new RS35 has a bit of a louder hum than I noticed with
my older unit.

 

Has anyone noticed this sort of thing with the newer RS35's, and if so, were
you able to do anything to address the issue?

 

I might consider moving the supply to another location, because right now,
it is on a shelf just above my operating position.  However, I will need to
be certain that the newer location gives the supply sufficient space for
ventilation.

 

I am not sure the problem is significant enough to return it to HRO, but I
would be curious if anyone has had a similar experience, at least recently.
