Bob, can you expand on the subject of PM alternator ripple? Didn't
realize that, nor the part about an old battery not being able to smooth
things for the system.
Thanks
Dan

Bob
There was a thread awhile back on battery chargers that helped
desulfonate a battery to prolong it's life. I wonder what was found
out regarding the units. Do they work as stated? Are they worth
buying? any suggestions as to brands/ sources?

Hey Guys, I have a question for those of you that have or are planning to
have music in your cockpit. I currently have a PS Engineering PMA4000 Audio
Panel. The panel is mono (which doesn't bother me) and has one input marked
as music jack. I have a Sony AM/FM/MP3 player with front and rear left and
right speakers. I am assuming that I will only connect one set, but which,
front or rear? Also, with only one music input, how do in connect the left
and right?
I called PS Engineering tech support and they said that maybe I should tie
the two speaker outputs together through a 10K resistor but they weren't
sure.
How have others done this?

Vince:
Does your Sony player have a had phone jack? If it does it most likely
has tied these channels together already and you can use this source a signal
for your audio panel. If not and/or you desire to go the other route, I
suggest using the front speakers using a Radio Shack stereo to mono adapter.
If your MP3 has the 5.1 digital format for surround sound, only about 20% of
signal goes to the rear speakers. I don't know if this helps, but this is
where I would start.

Dear Listers,
I was particularly touched this year by all of the wonderful comments
people made regarding the Lists and how much they mean to them. As I have
said many times before, running these Lists and creating the many new
features is truly a labor of love.
I will be shipping out the third and final shipment of Flight Bags and A&P
Text Books this afternoon. According to the Post Office, maximum delivery
to the most remote of areas is 8 days. I will have no outstanding Gift
requests following this shipment, so if you don't get the Gift(s) you
requested by, say, the 20th of January, please let me know via email.
I would also once again like to thank Andy Gold of the Builder's Bookstore
( http://www.buildersbooks.com ) who so generously supported this year's
Fund Raiser with both free and substantially discounted merchandise!!
Below you will find the 2002 List of Contributors #2 current as of
12/31/02! Have a look at the list of names there as these are the people
that make all of the services possible! I can't thank you all enough for
your support and great feedback during this year's Fund Raiser!
Once again, THANK YOU for making this year's List Fund Raiser successful!
Best regards,
Matt Dralle

Hey guys...
I know zip about electronics, that's why I follow this list, trying to learn
something. Just read and reread Mr. Nuckolls' excellent book. I've been
working on my panel, and couldn't wait for my backup GPS any longer, so when
the Garmin196 came out, I grabbed one off eBay... JA Aircenter. Excellent to
do business with JA , btw.
Anyway, I have it in my car, while I make airplane sounds, and it never fails
to get a lock almost instantly, in cloud-and rain-covered western Oregon. Do
you think there would be ever a time when this unit would not perform, even
with the thickest clouds?

Dave, Norm is correct that cloud attenuation is a minor player in GPS,

See the current issue of Kitplanes for an article on building an external
GPS antenna.

I'm using a Garmin 90 and sometimes lose coverage on cloudy days. Would
using
one of the externally mounted antennas improve my coverage? Everything
that I
see in Aircraft Spruce is a little bit on the expensive side. Any
thoughts?
