Please forgive me for piggy-backing this to a post totally unrelated, but I
am having trouble "post"ing articles, and "followup" seems to be working fine.

As mentioned in a thread last week, the Silencer headset from Evolution, Inc.
looks like the *deal of the century*.  Therefore, I am voluteering to become
the guinea pig for this new product.  I just called them and placed my order.

I was informed that it would take two to three weeks for delivery.  The guy
I talked to did *not* seem to be very well informed technically.  When I
asked him about problems I had heard about in early models of ANR/ANC head-
sets with regards to feedback, he stammered a bit and said "I hav'nt heard
of anything".

With the way the weather has been acting up here in Minn. I hope I get a
chance to try them out before my 30 day money back gaurantee runs out.

I will let the net know what I find as I use the set.

I ordered a pair on Oct, 30.  I was warned that they were on a two week
back order.  I will be sure to post a comparison when I get them.

I demo'd the BOSE, and tried the TELEX/ANR on the ground at OSH 1990,
but I haven't tried the DCs.  I didn't hear any hiss in either of them,
but I don't hear high ferequencies very well.

  Thanks to all who replied to my query about the problem I had with my
mike jack on the Peltor 7004 headset. It would appear that others had
encountered similar problems but often with DC headsets, so the problem
is not unique. I talked to the outfit I purchased the headset from and 
they were going to replace the mike jack for me. When I brought the headset
in they decided to not replace the jack (void the warranty) but instead made
up a patch cord - input jack and DC jack to plug into the intercom. It
appears to be working now with no trouble. Despite this minor problem I
would suggest that if a person is looking for a headset in the DC price 
range to consider this set - very comfortable!

seen a set of these, or have any additional info on which to base a

This is the kind of thing that will probably elicit five different answers
from four different FAA inspectors.  Some shops are comfortable with a simple
logbook entry.  Others like to do the 337 even if the radio was simply replaced
by a different make and model.  I think it's a call based on how similar the
radio/power supply/antenna is to the original equipment, (assuming this type
of radio gear is on the approved equipment list for the aircraft) and 
the experience of the installer.  I've seen it done with only a simple 
logbook entry and I've seen it done with the 337 form.  If you can 
get an IA to submit the 337, I doubt it can hurt.

What exactly are you looking for?  

  Avionics manufactures, such as GARMIN, would require a non-disclosure agreement
for those types of specs.  PC/kit companies seeking to provide an interface for
a product must typically sign an NDA for the specs.  

To some extent the policy is very important because it helps protect confidential 
information regarding the design of the box from competitors.  I notice that 
you are with Hewlett Packard.  Is this a company venture, or a personal interest?

I'm sure that there are many aspects to HP product interfaces which require NDA's as well.  So let's not be so quick to blow steam.

G'day,
 
A while back there was a discussion of knee boards,
flight bags etc.
 
Because I have rather short legs and thus need the
seat quite close (first stop) I find most of the
standard knee boards quite unsuitable. They
basically interfere with the control column.
Consequently I have a rather extensive collection.
 
The one I find most convenient I approriated
from my Naval Aviator son (ok, son if you want to
fly the Bonanza you have to give me your knee board!)
 
It's made by Hendricks Sewing Company of you guessed it
Pensacola, Florida and is reasonably cheap at $19.95
(oh, yes I bought him another one).
 
It's small at 5 x 7 inches, make of heavy black cloth, very thin, has
an aluminum back, has a clear pocket for a checklist, a clip
for a notepad and/or approach plates and attaches with 1 1/2 inch
wide strap velcro fastened. Their number C008B. The workmanship
is good.
 
The full address is
 
Hendrick Seqing Company
8252 Tabaid Lane

They also have other items that are quite reasonable priced.

Subject: Telex ANR 4000 report
Organization: Qualcomm, Inc., San Diego, CA
Date: Thu, 12 Nov 1992 03:28:18 GMT

Recently, while in San Diego at Montgomery Field, I stopped into 
Marv Golden's store intending to purchase a Peltor headset.  
However, there were none on display, but there was a neat new 
headset from Telex, the ANR 4000, on display.  As you might guess 
from the name, it is an active noise reduction headset.  I tried 
the thing on and found it to be quite comfortable and to offer 
very good noise reduction even before I turned on the electronics.  
When activated, the ANR circuitry was very effective at reducing 
the remaining noise a significant amount, although there is a 
noticeable hiss that starts when you activate the noise 
cancellation.  (This is pretty much inaudible in flight.)  Then I 
saw the price tag - 388.95 plus tax.  Yeah, it's more than the 
Peltor.  Yeah, my airplane's quiet already.  But I'm a gadget 
freak.  I bought it.  

When I got back to the condo I was staying at, I took it out of 
the box and tried it.  Trouble.  The active thing had become an 
oscillator producing a rather loud pulsing noise at about a 3 Hz 
rate.  So I put it back in the box and ran back to Golden's to get 
another one.  No problem with the exchange.  The new one tested 
fine in the condo.  

I left the next day for Bozeman, MT (home) in my 421C.  Planned 
flight time was just a little shy of 5 hours.  For the first hour, 
everything was great.  Then, the right ear began to oscillate.  
Different from the first headset, but just as annoying.  So I 
turned off the active canceller feature.  But I kept trying and 
after about an hour, the oscillation quit, not to return, at least 
not yet.  The remainder of the flight was fine.  Very comfortable 
for such a long duration.  

Today, I flew from Bozeman to Billings and back.  The headset 
worked perfectly.  I took it off when taxiing up to the hangar and 
was amazed at how loud everything seemed.  

It folds up into a neat package for packing in your flight bag.  
It's battery powered.  Said to go 40 hours on a set of batteries.  
Each earpiece has its own volume adjust.  Will provide stereo 
sound from an appropriate source.  I'm very happy with it.  I 
think I'll keep it.

  Their Phone number is 800-800-1020 & their quick response seems to be no!
That is they have a PCkit with a diskette/cable for uploading waypoints, but
they said they want to sell this themselves!! We need to find a manufacture
with an "Open Interface". Maybe best to find from Rockwell their spec. I 
understand this is the chip of choice anyway - 5 channel GPS receiver.

I have an oppertunity to get one of Trimble's new portable

and all the (seeming) goodies. Trying it in my Cherokee,
I acquired 4 satellites with just the built-in antenna.
With the "real" remote antenna on the top of the panel,
I got 6.

The primary use would be as a pseudo-DME (don't have a real one)
and get distance, ground speed, and time-to-station estimates,
as well as having something to carry around hiking and cross-country
skiing so that I can impress the Yuppies.

The above statements are true IF the battery is so dead that it
cannot maintain approximately 8 volts with a current drain of
about 10 amps (ignition coil + alternator field coil). That is
pretty dead!!! This assumes a 12V battery; double the voltage and
halve the current for a 24V aircraft battery.

Lead-acid batteries almost always recover to some extent after a
discharge cycle, and unless the drain was continuous over a long
interval (master left on overnight or longer) there should be
enough residual capacity to enable the alternator after a
hand-prop start.  [Your mileage may vary!  :-) ]

Um, if you're referring to the San Diego Hawker-Siddley (sp?) crash, she

of course, was an excellent example of how IFR pilots can die by letting
their VFR skills get rusty.

I was discussing the issue with a Sunnyvale (near Moffett for those out
of the area) resident, and her complaint about the ballot question
lied in the idea of "general Aviation is NOT a legal term".

For those unfamiliar, there was (evidently) a ballot question for
residents around Moffett to turn it into a GA airport. She said she
voted NO because the evil politicians could then move some "commercial"
operation in there like FED EX, or something. She said there was no
legal meaning behind General Aviation, and that's why she voted NO.

Unfortunately, we have the exact opposite happening.  Anyone else
remember the Cosby show where Cleo (I think that's his name)
decided he wanted to learn to fly.  By the end of the show Bill
had wisely let his son find out that it cost $5000 to learn to fly
and $100/hr to rent a plane - and that flying was SO expensive that
no right minded person would want to do it.  So his son realized it
was an impossible dream and gave up the idea - making Dad happy to
have saved him from such foolishness, and Mom happy he was not going
to be killed in little planes.  Ain't it great that "father knows best"!

The only show on currently that portrays GA is "Wings", and they've
crashed into the ocean.  Just a fine example.  Oh well, if there
aren't any planes being built, I guess we better not encourage more
pilots - hate to make more demand for the old buggers.

Grumble, grumble, grumble....

From what I read in Flying and other aviation magazines, private pilots
were the first to help after the hurricane in florida by transporting
supplies using their small private planes.  I was rather
dissapointed when I didn't even see a remote mention of such news in 
any of the national reports.  I believe that was a unique opportunity
for GA to get some good publicity.  Maybe there is still time ?

You will probably find this habit of blanking the 1200 vfr aircraft more
commone than you would care to know about.  Remember, the primary concern
of ATC is to seperate IFR TRAFFIC FROM IFR TRAFFIC.  Anything else is on a
work load permitting basis.

Far to many VFR pilots place to much emphasis and reliance on ATC to do
their flying for them.
