6. The time of owning an 830 did not coincide with the phase in
my life when I experienced a severe loss of self confidence. I explained
more crap snipped
A 'severe loss of self confidence' could also be described as an inferiority
complex. In your case Airy, you do not have an inferiority complex, you
simply ARE inferior.

I recall this was a favourite of another poster within this group - start

Your shameful support for the gangrenous degeneration that
is the M3/CB licence seems to have you proposing that because
you find fault, in YOUR opinion, with the technical viewpoint of those
who aspire to be _REAL_ Radio Hams, then that is full
justification for admitting the M3/CB licensees with no technical
viewpoint whatsoever. If that is your argument, then I disagree with you.


gangrenous degeneration, the cb'er etc etc

I have a theory that you are not a real person but a machine with a
collection of pre-programmed phrases.... rather akin to the Texas

And not many people know that!



Watch your S/N ratio deteriorate as the noisy sun tracks through your
satellite dish's beamwidth.

A company I used to work for used one of the Eutelsat birds for data
distribution, and twice a year we saw our Es/N drop by 10dB for about
four minutes. It was at 11.20-ish on the 11,12 or 13th October and

I'm not familiar with that particular INS but the technique was (quite)
widely used. My background isn't on the civil a/c side but I'd be very
surprised if many civil a/c were not using a LINS these days- often as not
with a coupled GPS. The big US companies (Litton, Honeywell, etc) saw the
potential and threw $ at the problems. The base cost of a LINS tumbled and
the low maintained cost did the rest. I had a tour of LINS manufacturing
facility back in 1986 and they were already starting to treat LINS systems
as a commodity product (ie built to stock not order)- almost unheard of at
the time.

Prior to this there were some amazing techniques used to make gyros- my
favourite (although I never worked on them) had a solid 'ball bearing' which
was held electrostatically and rotated at high speed. I forget the details
now but, when I learned of it (in the early 80s I would think) it seemed
almost too clever to be true.

The advent of the 'cheap' RLG (ring laser gyro) saw off some interesting
techniques which were replaced by things 'without eye brows' ;-)

Consoling yourself by consorting with the NEGATIVE NERDS
and muttering in the corner of the room with them will not restore the loss
of face that you have experienced by supporting the gangrenous
degeneration that is the M3/CB licence, OM.

As to your comment about being out of my depth, it is noticeable that

I think you are on the wrong frequency with this one OM. The world of
telecommunications must run on one master oscillator. Call it GOD if you
will. There is a heavily guarded master oscillator somewhere on earth that
keeps everything in sync. I think it is somewhere in New England. All you
have to do is get a feed if this master clock and phase lock loop all your
ham junk to this frequency. What do you think would happen to all the worlds
telephone, television and satellite gear if everyone had their own free
running oscillators? Chaos. I doubt you can cut a piece of quartz to any
predictable frequency without specialized equipment nor keep it at a
predetermined frequency without a very accurate crystal oven. Remove just a
pubic hair of quartz and all is lost.

Well, there was the HRG (Hemispherical Resonator Gyro)which was touted
as a low cost replacement for the Litton and GM Carousel systems, but,
as you rightly comment they were beaten out by IRUs with RLGs.

The Boeing 777 has a unit called an ADIRU which comprises 3 IRUs and 3
ADCs in one unit with built in redundancy.

GPS inputs to the Flight Management Function come from MMRs (Multi-Mode
Receivers) which comprise VOR/ILS/MMR/GPS/Marker in one box. (There are
three of these per aircraft).

All very reliable compared to the 70s/80s type gear.
