Hi Malcolm.
if you want to import from the UK an immaculate Extra with Jabiru and
only 90 hours from new. I am your man.
Nothing is selling in the UK at the moment. Guess the squeeze is hitting
us all.

The ultralight's use by smugglers has become so ubiquitous that Congress
recently updated (2012) their definition of "aircraft" to include
ultralights and, therefore, make those caught smuggling drugs with them
subject to the same penalties as other aircraft under the Tariff Act of 1930
<http://uscode.house.gov/download/pls/19C4.txt> . The legislation, known as
the Ultralight Aircraft Smuggling Prevention Act of 2012, was the last bill
sponsored by Rep. Gabrielle Giffords
U.S. Customs and Border Patrol is spending big - just under $100 million -
to combat drug smugglers who use small aircraft worth only a few thousand
dollars
Last week the CBP awarded SRCTec
<https://www.fbo.gov/index?s=opportunity&mode=form&idde95b2a106cf5d726dce
e9ed734a1f&tab=core&tabmode=list&=> , a New York-based research and
development company, a $99,955,087.00 contract for a real-time detection
system that is specifically designed to pick out ultralight aircrafts,
slow-speed rudimentary manned planes that have a very small radar signature,
on America's southern border.
Often little more than an airframe and engine - that can be bought online or
constructed at home from kits for a few thousand dollars. Ultralights
do not require a pilot's license Did someone forget to tell us that.
This was reported by ABC news. Thought this might be of interest to the
list.

George,
Tried that first,found that the GPS was sending a signal through it's power
cord that the radio antenna was picking up.Put chokes on the radio power c
ord and the radio antenna lead that helped a bunch.Chokes on the GPS power
cord did not seem to help.Some noise can be stopped by covering the headpho
ne adapters with my hand.The intercom has a double filtered power supply an
d it is quiet.The caps for the radio power and alternator output are next.
Thanx G.A. PS got the squelch from (icom a5) from 10 down to 4 so far,but
weak signals still come in with engine noise from the Jabiru's electric's.

Large is always good. I don't know diddly about the 912 but on other simila

problems I have found a handful of small caps liberally sprinkled about the
system works well too.
A thing that just flashed on me... what if you disconnected the electronics
from the airplane electrical system in order to determine how much of the
problem comes from the power supply. Maybe you could temporarily power stuf
f
from a small battery, as a test. This might help you focus your attention i
f
the problem is in the power being supplied.

Yes. You guys are right.

But we don't know what type of SWR meter another fellow might lay hands on.
Some work better over a wider range than others. I would think that if you
weren't sure, you could just put a 50 ohm dummy load (or whatever your
system is designed to work with) on there and see if it shows a zero RSWR.
But I am not an educated, experienced ham guy. I'm sure this is not the best
suggestion for this situation.

Subject: | Re: New Firestar II owner - question about elevator oscillations |
I called Kolb and talked to Brian and he had the same suggestions as those above.
I tried them all and eventually what worked is the trim tab.
I built the trim tab so that it adds nose up pitch per Brian's instructions. My
503 Firestar now trims out around 54 mph and 5,400 RPM versus 63 mph and 5,800
prior to adding the trim tab. The elevator has never fluttered at this slow
speed.
Now when I pitch forward to increase speed, there is additional control cable tension
and stick pressure. Basically, the pilot HAS to keep a hand on the stick
to maintain 63-65 mph - the area where the elevator used to occasionally flutter
in turbulence.
I am slowly building my "bump" tolerance for winds and thermals, but the elevator
has not fluttered in any conditions since adding the trim tab, so for now at
least, I consider the problem solved.
Thanks again for everyone's input,
Eric

I would not recommend any guessing in this situation or you are likely
going to ruin your radio. The 50 ohm dummy load is not going to do you any
good with your antenna. It is only designed to help you with your
transmitter.
Any SWR meter (except maybe the CB type) will tell you what frequency
range(s) it will cover and the power it will handle. Someone mentioned the
Bird meters before and those have to have the corresponding 'slug' to
measure the target frequency. They are probably some of the highest quality
meters out there. Here's one I found on eBay.

*I don't know if anyone has said this already, but in case anyone does not
understand, the lower the SWR, the better your antenna will work on
transmit. Many people believe that you have to have power to transmit
further, but it is actually far more important to have a well tuned antenna
than more power.*
*SWR or Standing Wave Ratio over simplified means the ratio of how much
power is emitted from the antenna vs how much is reflected back to the
transmitter. Too high of SWR will ruin the final amplifier circuit of your
transmitter. Some radios have a built in protection circuit so they will
not transmit with higher than 3:1 SWR.

Seriously! Amateur Radio operators are to radios what Kolb pilots are to
experimental flying. Just think how eager you would be to help a newby
pilot learn how to fly or get their plane flying. That's how amateur radio
guys are about antennas and radios. It's their passion.

Another popular one is the MFJ-259b.
instead of buying an swr meter,,,, an antenna analyzer is an other
good tool..... it is basically a transmitter that will go from 2 MHz
to 500 MHz,,, and as you adjust the frequency,,, it will report the swr
along the way. it is very low power, it will help find the
resonant frequency of any antenna. so if you find a ham radio club,,,
ask if they have an analyzer, makes it really fast and easy.
