For aluminum electrolytics the answer is yes, there is a functional
difference. If a voltage far below the rated voltage is applied, the
insulating oxide layer won't completely form and the value of the
capacitor will be drastically reduced from it's marked value. For
other types of capacitors, using a capacitor below it's rated voltage
is not a problem.

Subject: FT-890AT Mods
To: info-hams@ucsd.edu

I am considering the purchase of an FT-890AT and was wondering if anyone
knows of the MARS mods for this rig.  Also, does this open up transmit
for the full range of receive frequencies or just certain segments?  Any
general comments on this rig would be appreciated.

About three years ago, I was warned by two people who had experienced poor
service to stay away from Jun's.  (Sorry I don't remember the details).  I
recall followups in this thread from folks that posted both good and bad
stories of their service experience from Jun's.  I find the most useful
aspect of postings along these lines is the followups, both agreeing and
rebutting.

Michael, I find it curious that you took the time to go to all that trouble
to act in Jun's defense.  Do you have any personal experience to indicate
that their service is as good as they claim and does not warrant Axel's
dissatisfaction?  Do you have some affiliation with Jun's we should know
about? :)

The subject line pretty much says it all - a friend of mine is
trying to locate an old friend.

To: info-hams@ucsd.edu

Well, I have recently passed the TECH exams and I am in the process of
learning code.  Since the next step up for me is general class, I am
shooting for 13WPM.  Since I am doing that anyway, I would also like to
study for the general exam.  So, if anyone happens to have the general exam
question pool handy, could you please send it to me?  Thanks.

Sure. Use MiniMUF in conjunction with the solar data transmitted by
WWV. Operate on the band closest to, but below, the predicted MUF
and you have your best chance of success.
