[future arguments against amateur radio deleted]
Yes, you have made some good points on possible future attacks on
amateur radio. Note that amateur radio is more like social security
than like gun rights. It is a socialistic allocation of confiscated
property. Its justification is for people to fiddle around with new
technology at the government's expense and provide an alternative emergency
communications network. Just like a park which can be used by FEMA to put
up tents or play in, Amateur radio uses the radio waves. It has one-up on
FEMA because it is private individuals who are responsible for maintaining
their equipment which they can volunteer or allow to be coopted in the event
of an emergency.
Repeatedly, Amateur Radio has proven itself to be an effective means to
provide volunteer help in emergencies. Even if the radio waves were one
day to be regarded as property and not allocated loot as they are today,
there would be a role for reserving a portions of the electromagnetic
spectrum for this purpose for the same reason that the government needs
military bases to defend its citizens.
As for the FCC rules on Amateur radio, because it is more like social security
where you sign agreements putting yourself under the auspices of the
Federal government, it is most emphatically unlike gun issues in the current
political climate. When you sign your license application and pass your
test, you are promising to obey the laws as applicable to amateur radio.
You are submitting yourself to a series of regulations that prescribe and
proscribe your behavior which include some potentially Draconian penalties.
One difference from social security though is that you're not tricked into
joining it out of ignorance. Amateur radio licensees got into the service
with both eyes open, putting it head and shoulders above most government
activities that restrict human life.

never complain about the budget or power of FEMA, the FCC, etc.
You'll never see anyone admit to these motives openly, but they will exist
soon if they don't already. Prohibition movements have the same form
whether one is trying to ban alcohol, or guns, or amateur radios.
I give amateur radio another 15-20 years if current trends continue. The
same for private aircraft. Private automobiles will probably last 30-40
years, but no longer. The future will not be pretty, unless we change
course soon.
It disheartens me to hear that the consensus among amateur radio types is
that gun control is a good thing. It may come to the point where we need
them to coordinate our opposition to the State, and they need us to guard
their stations.

Amateur radio is a highly regulated communications medium, unlike internet.
Radio operators are getting a favor from the federal government that is in
their personal interest to maintain. The feds frequently treat them well
too because they need amateur radio operators, even today. The typical
individual who sticks with the licensing requirements of amateur radio,
especially the advanced licenses, tends to be quite loyal to the central
government operating out of Rome, er Washington. It makes a big difference
when there someone is getting a major favor from the government when it
comes to judging other activites thereof.

The 7.2V/700mA came with the radio when i got my TH-78E.
It's small and fits completely inside the rig. I mainly use it when i
carry the 78 around. Good for listening but don't talk too much.
The 12V/700mA doesn't make sense to me. It's too large and at 12V the
current goes up to more than 2A, which is too much for 700mA cells.
It's easy to kill a cell by reverse charge and the pack is sealed so you
can't replace individual cells. You get a bit more power out but if the
other side can't hear you at 2.5W it probably can't hear you at 5W. Get
a better antenna instead.
IMHO the 7.2V/1100mA is the best choice. I can chat all night long and
then it won't go down all in a sudden. The charge circuit inside the 78
will only supply about 60 mA of charge current so it takes some time to
recharge, but then you won't overload the little wall cube and won't
do any harm to the pack even if you leave it on for a week.

With 6 Duracell alkaline you get 6*1.5V -> 9V. Output power maybe abt
3.5W. I think those cell have a capacity off abt 1700mA. With 6 NiCd
cells you get 6*1.2V -> 7.2V. The sticker on the BT-8 says: don't use
NiCd. Of course i ignored that and got me 850mA cells. The only problem
was that the cells were not charged inside the rig. I was too lazy to
pull them out for charging and modified the BT-8 at bit.

Don't know any. Get a BT-8 and make your own pack. Then you can use
any type of cells you want and also can access individual cells. I plan
to get a set of those new NiMH cells that claim a capacity of 1200mA.

Subject: FT-11/41R PL Tone Problem: Followup
To: info-hams@ucsd.edu
Disclaimer: The following is for informational purposes only.
Use at your own risk, and any liability from using this information
is yours.
---------------------------------------------------------------------
History: Those that saw my earlier post are aware that the Yaesu
FT11/41R radios have a problem with the PL tone generation. If
used without the optional FTS-26 tone board, the PL tones are
slightly off in frequency, being too high.
Solution: Yaesu has recognized this as a problem, as has issued
a service bulletin TB9420 to deal with this problem. The fix
involves changing the value of one of the loading capacitors used
with the microprocessor crystal. The principle being that lowering
the clock frequency will lower the PL tone.
Yaesu's bulletin directs changing C2018 (33 pF chip cap loading
the output of the inverter on the CPU) to 39 pF.
Warning: Those of you contemplating this should be made aware that
the chip cap less than 1/2 the size of the COG size chip caps -- I
would not attempt this without a microscope and a FINE tip.
Changing the capacitance to 39 pF did indeed lower the PL tone,
but was insufficient to fix the problem. Only after adding another
7pF (total 46 pF) did the PL done fall within range of a local
repeater.
It may be that this particular situation was bad luck (i.e. high
crystal, low caps, low reed on the repeater).
Yaesu has started using the larger capacitor beginning with
lot 13 (11R) and lot 12 (41R).
If you have a problem with PL tones, and opt to return your unit,
you may want to insist that they check the value of the PL after
the mod -- they may have to put an even larger capacitor in there
(e.g. 47 pF)
I am happy to report, however, that the above mod has fixed
the PL problem for me, and the local repeater now likes the 41R.
Other than this minor (albeit frustrating) glitch, the 41R
is a neat unit. VERY small -- less than 1/2 the size of the 530,
and performs well for its size. The standard 4.8 V pack is
compact, but keeps the power output to 800 mW on high and 200 mW
on low, which may be a problem for those hard of hearing repeaters.
Speaker audio is improved over the 530. Your mileage may vary.
Related Item:
The extended RX/TX mod for the 41R is identical to that for the 11R.

Is there any particular type of computer / operating system combination
this needs to run? Is it in binary or source format? If source, what
language does it use (or do we just assume it's in C?), and does it use
any special libraries (e.g., curses, X11 libs, etc.)?
I've been looking for a good X-based satellite tracking program to run
here under Linux (a freeware, Posix-based UNIX)---is this program what
I've been looking for?
