I have the same problem. When I saw this, I called tmobile and they won't
lock my payasyougo phone that my husband gave me as a gift a few months
ago.

They said I didn't pay enough. When I asked to speak to the supervisor, he
said tmobile asked motorola to make the phone unlockable so that nobody but
tmobile can ever lock the phone in ten years.

He said we should not have bought from tmobile if we wanted to use the
phone outside the united states and that I was out of luck.

I've learned my lesson but too late. I'll never buy an unlockable phone
from motorola again!

I wonder why motorola even makes an unlockable phone in the first place.

Where can I get unlock codes for the new T-Mobile Motorola V195 cell
phone?
The sites below told me this phone is not unlockable.

On Friday, I bought the pay-as-you-go T-Mobile Motorola V195 for $98.99
because the salesman was touting it as the best phone on the market for
the
money but T-Mobile tells me I have to wait months before the phone can be
unlocked. I'm beginning to believe them. I am going on vacation in
Australia in two weeks and I bought this phone so I could use the GSM
service there. But I can't seem to find _anyone_ who can unlock it!

Everyone I called said this is the only Motorola cell phone that
absolutely
canot be unlocked by anyone to date!

I tried everyone in the book by googling for "Motorola v195 unlock" which
got me the following web sites

This site says the phone is not available (which is wrong)
http://www.cell-unlock.com/motorola-v195-unlock.htm

This site says the Motorola V195 can be unlocked but when you call them in
Malta, they say they can't figure out the unlocking for this cell phone
(+356) 998-555-72 support@unlockitnow.com
http://www.unlockitnow.com/Motorola/V195.php

These guys say they don't think anyone can figure out how to unlock this
Motorola V195 cellphone because they tried and failed and say it can't be
done
800-891-0522 http://www.unlocktotalk.com
800-891-0522 http://www.thedssguy.com

These people also have a page that intimates the Motorola V195 can be
unlocked but when you call them, they say they've never done one
support@unlockstore.com
http://www.unlockstore.com/motorola-V195-unlock.htm

These guys have a web page but nothing is on the web page to unlock the
Motorola V195 cell phone
http://www.instant-unlock.co.uk/acatalog/Motorola_V195_Unlock.html

So far, it seems like nobody can unlock this new T-Mobile Motorola V1945
cell phone.

Do you know _anyone_ who can really unlock the Motorola V195, reputedly
the
toughest of all cell phones to unlock today?

believe that I need any capacitor with the PTT switch, but if you know
better I'd love to hear all about it.

I'm having trouble sourcing the U-94A/U, so I'd like some help on that
too.

Mickey-

Check out the Astrocom website at
http://www.astrocom-electronics.com/

They have a downloadable catalog, but it is 23 MB. You might send them an
eMail explaining your project, and ask for technical information about
your particular headsets.

If the headsets can be used, you may want to just wire new connectors on
them, and not worry about adapters. The U-94 connectors might cost more
than you think!

Ditto the previous comment on impedance mismatch. Ham/LMR HTs are

8-16 ohm speaker impedance, vs typical 600 for aviation headsets.

I played with an old British aviation headset once, setting it up for
a Yaesu ham HT...the audio was useable but very tinny driving 600 ohms
directly. Would have been better with a 600-8 ohm transformer. The
mic element audio was way too low to be useable and I ended up
strapping an electret element to the original mic...worked OK, but of
course it was no longer noise cancelling and was way too sensitive.

However, yours being old military heli sets, they may be lower
impedance.(?) First of all I would try ONE headset with the speaker
& mic audios mocked up to the right connectors for the HTs. I would
plan on cutting off the existing heli plug and wiring thru a tiny box
to hold a PTT switch, and any matching network you may need.

Or...sell the headsets on ebay and buy what you really need...!

Nope, 600-ohm was the standard when I was a radio operator for Uncle

considered "old" even if'n I'm not.

Mickey,

Back in the olden days, I was a Comm Tech in the USAF. One of my
accomplishments was designing a mod for C-12 aircraft (Civilian Beech
Queen Air), which used the non-mil Headset/Microphones. The aircrews
wanted to use H-157 Headset ($57.00, and available on every USAF base in
the world) instead of special order David Clark Headsets at a cost of
over $300.00 at that time. There is a audio transformer that was
specified in one of the radio test sets to do just what you want. It
even was pre-wired with a U-92/U on one end. You would need to add the
connectors for H/S and Mic to the attached cable. The transformer is
MX-!#^*%/ARC. This worked great for the crews, and I was awarded a
substantial sum for the suggestion/proposal. The aircrews did not
want/need the PTT feature you are wanting. I will search through my
papers for the exact part number of the transformer. FYI, the
transformer is housed in a cylindrical can about 1.5" by 4" with 2
cables attached, one cable has a U-92A/U attached, the other has no
termination.

Would that it was that simple. These things are scarcer than hen's

There is some emotional satisfaction to be derived from solving
problems.

Anytime you rewind a motor or alternator, you want to use the same gauge
wire. Your alternator was designed with 22 AWG, for the number of
turns, the dc resistance, the current through it, the power dissipation,
and the space available. If it would work just as well with 24 AWG,
they would have used 24 AWG originally. If you're going to all the
trouble of winding these coils, placing them, and wiring them up, you
might as well use the right size wire to start with!

Oh, I don't know . . . where's your sense of adventure man?

All engineering is a matter of compromise. You assume the factory got
it right

- the original lasted 2 years my first repair lasted 5. It would
still be working if I'd thought to serve some stranded wire to the
start and finish ends and not used Teflon tubing to support the wire.

There are some alternators that last until the brushes die from wear
or the diodes rust through - this alternator has a very high, well
documented, rotor failure rate. I'm assuming the factory did not get
it right.

I ran some calculations on wire size and cross sectional area of the
coil. All things being equal - same magnet wire insulation - the
resistance goes up (as wire gets thinner) the current goes down
(greater resistance) but the magnetic field strength stays the same if
the cross section (filled with wire) stays the same.

The power dissipation goes down as the wire gets thinner, lower
current producing the same ampere turns in the same available space
assuming the voltage stays constant - higher efficiency.

I'm committing two sins here - going down in wire diameter and
increasing insulation thickness - fewer turns of thinner wire.
Conductivity may be better because it looks like silver plating on the
wire. I wish I'd measured the 1,000 foot reel before I started using
it . . . but I bought it for Tesla coils not alternator rotors.

The downside of using very thin wire is it is more likely to break
under stress, physical or thermal cycling. At some point wire
insulation may take up more room than wire itself with very thin wire
gauges - but within the practical range of several gauges it shouldn't
matter all that much. Theoretically.

I would expect the output to go up slightly with thinner wire due to
an increase in efficiency but don't expect it to be enough to be worth
changing to a different gauge. I'm just trying to save a buck on
wire cost.

I have Tefzel insulated wire I already own . . . . Copper prices
have doubled in the last year or two. One pound was costing me $12,
one half pound now costs $35 from the same source - but in larger
quantities it has (only) doubled. I need about 12 ounces.
