| Subject: | [PLEASE READ] Why I Have A Fund Raiser... |
Since the beginning, the Matronics List and Forum experience has been free from
advertising. I have been approached by fair number of vendors wanting to tap
into the large volume of activity across the various lists hosted here, but have
always flatly refused. Everywhere you go on the Internet these days, a user
is pummeled with flashing banners and videos and ads for crap that they don't
want. Yahoo, Google and that elk are not "free". The user must constantly
endure their barrage of commercialism thrust into their face at an ever increasing
rate. Enough is enough, and the Lists at Matronics choose not to succumb
to that.
That being said, running a service of this size is not "free". It costs a lot
of money to maintain the hardware, pay for the electricity, air conditioning,
maintenance contracts, etc, etc. etc. I choose to hold a PBS-like fund raiser
each year during the month of November where I simply send out a short email
every other day asking the members to make a small contribution to support the
operation. That being said, that contribution is completely voluntary and non-compulsory.
Many members choose not to contribute and that's fine.
However, a very modest percentage of the members do choose to make a contribution
and it is that financial support that keeps the Lists running. And that's
it. To my way of thinking, it is a much more pleasant way of maintaining the
Lists and Forums. The other 11 months of the year, you don't see a single advertisement
or request for support. That's refreshing and that is a List and Forum
that I want to belong to. I think other people feel the same way.
Won't you please take a minute to make your Contribution today and support these
Lists?

Thanks guys
I ran the radio positive and negative leads directly to the battery with a
in line fuse
That seems to have solved it :)

Subject: Re: Pulsar-List: Radio Engine Noise
Those in line noise suppression coils are a great step in resolving the radio noise.
If the noise is something that has progressively gotten worse, I would first expect
a weakend connection. Weak grounds are hard to isolate because a radio can
source its ground for the power source from many places (the power lead itself,
the headset jacks, the radio's antenna all use ground connections). I once
cleared up several problems, radio noise, a gauge reading inaccurately, by
simply cleaning and making a better battery negative to the engine casing cable
better (only after checking and tightening every ground connection behind the
instrument panel.
The reason I think there is a weak connection also is the noise is more noticeable
on transmit. A radio draws very little power when receiving, but when transmitting
the radio draws many times more power, which when depending on a poor
connection, more, ignition noise gets coupled through the wrong path (i.e. antenna
ground, headset grounds) and your radio ends up more vulnerable to noise.
With our Rotax engines, there is allot of vibration that every connection has to
deal with, and electrical terminations that look okay can add a couple of tenths
of ohms of resistance that propagate noise issues.
My suggestion, is first check every ground path from radio input power, through
the connection to the starter battery, through the engine ground. Then do the
same for the positive 12 volts (typically red leads).
If you choose or just want to try the inductor (in line coil) you can not only
get them at Radio Shack, but any major auto supply (Pep Boys, AutoZone, Advanced
Auto) sells them as well and may be a bit cheaper.
I hope this is of some help.

Had same problem.
Went to Radio Shack bought a couple noise suppression coils. Ran leads from voltage
regulator through them. Killed the noise.
Learned that from the electrical engineer at the last Pulsar gathering. If he
is listening maybe he can be more specific.

Guys, I have located a complete, Aerodesigns, Pulsar XP kit. It is the fast
build kit as shipped from the factory, complete minus the 912 engine with
no builder work done. The wings have the leading edge attached and the
tanks are ready to be closed but should be coated again. These are the
composite spar with composite wing skins and the top skin is already in place.
The
fuselage halves have been joined.
Missing from the kit is the two sheets of flat composite material which is
no big deal. All hardware appears to be there including engine mount for
the 912.
Here's the deal, the owner wants to sell it, is never going to build it.
We, as a group could purchase the kit and use it for glass plugs to make
replacement parts for our aircraft. The second option is to list it and let
someone purchase it, build it, and enjoy flying this great aircraft.
So, if there is enough interest for the group to own it I will make
arrangements to purchase it and work on locating a shop that can make some molds
for us. This will not be a cheap endeavor, besides the cost of the kit, each
time a part is needed, the purchaser will have to buy the mold and part
and donate the mold to the group, and there is the issue of forming a limited
liability, not for profit, entity to manage the assets, no small task. I
would want help with this project, if we decide to do it, I will need help
with organizing and running this adventure. At no time would this be a kit
manufacture, this would be strictly to support those that are building or
flying.
Give it some thought and please feel free to ask questions and present
ideas. To me, this is a way to insure you can get the replacement parts you
need to keep flying. I do not think you will ever get your money back, unless
you are one of the unfortunate ones that has a mishap and needs composite
parts to repair the aircraft.
Maybe this is just too weird of an idea. I have tried for years, to
purchase the Pulsar tooling in Central America, but that appears to be
impossible, so this may be the only way we will ever be assured of having the
parts
needed to keep our planes flying.
Let me know what you think. I could purchase the kit and part it out too,
and may take that approach if we do not have any better ideas.
