是啊,得转移阵地了。卡机和卡的差别就在这里,
Wrong, JerryG, absolutly wrong! Our receivers
are never use card. you don't know how powerful it is. AMC4 is a
little piece of cake for our receivers. we can receive all from 121w
to 61w, either di&h or be\/. We don't care those totally 14
channels to be getting lost.
to 中国BEAR: yes. ultra for
di&h only, pansat for both. ultra can be moded and then, act as
pansat in order to receive be\/. to Anaconda: sorry to hear that.
lifetime or lifetime ultra? if it's ultra, you should flash with
Al7bar FTA Ultra_040506_232_api(NTSC).bin. and you don't need a
boot.bin anymore. That boot 6 is a fake, before you flash your new
one, read it carfully always and wait for a few days to see how the
others say. I'm so sorry that i have no JTAG tools to help you. i
have ultra-virgin-IRDmem.bin but it's no use w/o JTAG.

I knew your receiver can deal with all channels
descripted by Nigravision. And I heard these Chinese channels will
go to Di&h. I have a question, when Nigra2 is popularized, can
this receiver deal with it? Or will it become
garbage?

福利土埃啊:pansat2500A是N制的,在北美销售的,以前有2300A(N制)和2300M(PAL制),没见过2500。可以买2500A。EBAY上有。
260CAD, FREE S/H。 TO Anaconda: GOOD LUCK for good try, MAN。 TO
JERRYG:1. AS I KNOW, FTA Receiver is able to deal with other
encription system but irdeto2 or PowerVu (a commercial encryption
system, no hack). 2. about nagra2, i don't care when it's coming
or not. "If there is a will, there is a way". FTA Receiver will
never goes into the garbage bin. even being screwed, FTA must be
working on fta, nothing will be worried. Just my cents. and some
thoughts posted on other forum:
It's just a matter of time
before there is a FIX for Nagra 2. The only way they (Satellite
Companies) can create a software program that our guys can't hack,
is to bring the technology from Mars, or some distant plant - with
different technology than ours.
Now i am know genius but i
know my math They are swapping 4 million cards and at the end of
last year the claimed to have 12 million customers now doen't that
leave a lot of people in the lurch there.Considering there are an
average of 2 recievers in each home thats 24 million recievers.i
will say for arguments sake that half are the new cardless ones but
i know that can't be true,Anyways 12 million recievers that need
cards and they are replacing 4 million only.Sounds more like they
are just testing a new card from the nagra people to see if its
effective in preventing piracy,so i see atleast two years before
this nagra 2 is in full effect and the old stream is shut sown.trust
know company in there right mind would piss off 4 million customers
especially with some new sat companys coming on line
一米多高?

guys ,
what kind of linear LNB you use for G3/t5/121 ? standard or
universal .
I copied this from Al7bar...
Point Of View
- Universal LNBF's There is a growing number of people coming to
the forums and reading about the added value of having an FTA KU
band dish in addition to their DBS dishes. I am very happy that the
FTA hobby is growing as people discover the benefits of having the
capability. Also there is a growing number of people that, when
ordering their FTA receiver, are going ahead and getting a package
deal with a thirty-something inch dish and universal LNBF. They are
learning the virtues of motorizing their dish, and some are picking
up a Stab or SG2100. When these people get their newly acquired
equipment they are anxious to play, and frankly I don't blame them a
bit. I like to try to help people get the most out of their system
with the fewest headaches. It gets difficult at times when people
want to combine and compact their systems and be able to use one
dish to perform on several bands. I've made many posts about the
fact that sometimes DiSEqC switches just don't like to be too far
away from the receiver. On a lot of the receivers coming out today,
for some reason they sorta forget to include 0/12 volt switching as
part of their feature set, so that switching mode can't be used.
That leaves 22khz switches, but with a ton of people getting
universal LNBF's, then it gets tough to use those switches. I just
wanted to look at the trend of universal LNBF's and share my
thoughts about these devices and ask...are they really worth
it?
Our North American KU band satellites primarily uses two
frequency bands. The FSS band is from 11700-12200 MHz, and uses
linear polarization. The DBS band is from 12200-12700 MHz and uses
circular polarization. Generally because of the polarization
differences it's easier for most people to use two different LNBF's
to tune these services. In Europe, Africa, and Asia, they have two
lower bands of 10700-11200 and 11200-11700 MHz linear. They also
share our 12200-12700 band, but it is linear where our DBS band is
circular. Universal LNBF's were developed to be used in those
locations where several different frequency bands using the same
polarization are used. By having a device that worked like having
two or three LNBF's in one, all frequencies could be tuned with one
device and one dish. The equipment that we have come to know over
the years as FTA equipment in this country is the equivalent to DTV
or DN in other countries. They aren't stuck with having to obtain,
lease, or buy equipment from their programmer, They just select the
brand of receiver they desire or can afford, obtain a CAM and card
from the programmer of their choice, and subscribe. The FTA type
receivers we know today have been in use in other countries for many
years. The universal LNBF is a mass produced item that has made it's
way into the American market in abundance. It is a good performer,
but it has it's drawbacks.
I won't get into oscillators and
mixing and the sums and differences, but in order for the universal
LNBF to be able to tune such a wide range of frequencies, it has to
incorporate two local oscillators (LO). When the lower frequency set
is needed it uses the lower frequency LO, and when the higher set is
needed it uses the higher LO. There has to be an automated way for
the receiver to tell the LNBF which LO it needs, so the uni LNBF
uses a 22khz signal. If I remember correctly, when the receiver
sends the 22khz signal the LNBF uses the higher LO, and when it
doesn't it uses the lower LO. The receiver is usually preprogrammed
with a "switch" frequency, so that when setting up the particular
satellite, if "Universal" is selected as the LNB type, and a
frequency above 11700 Mhz is selected, it turns on the 22khz signal
so the LNBF will use the correct LO frequency, and if it's below
11700 Mhz, it turns the 22khz signal off. What this means is that
the receiver is tying up it's 22khz system just to deal with the
universal LNBF, and in order to use both frequency sets, you won't
be able to use any kind of 22khz switch. With 0/12 volt switching
not being included in receivers much anymore, that just leaves
either DiSEqC switching or manual switching...two choices that can
have their own drawbacks.
In North America the only place we
see any real use of frequencies below 11700 are with a few
satellites over the Atlantic, mainly PAS9 and a couple more. These
satellites have just a few Spanish language channels, and the two
Atlantic Bird satellites have a handful of Arabic language signals.
Most people will never be able to even see the Atlantic Bird sats,
with the exception of the far right coasters. But for most people,
the advantage of having a universal LNBF is far outweighed by being
able to use 22khz as a switching method. In the case of forum member
Chance and his desire to mount a DBS LNBF beside his uni LNBF on a
motorized dish, it would be easy to stick a 22khz switch after the
motor to switch between his two LNBF's, but because his linear LNBF
is universal and wanting it to be able to receive both bands,
switching becomes more difficult. About the only alternative is to
use a DiSEqC switch after the motor, with all the problems it can
introduce.
Standard LNBF's are decently cheap, usually less
than $20. The point I'm trying to make is for all the folks coming
on board the FTA ship to think their systems through and decide if
it's really worth it to give up a fairly reliable and valuable
switching method just to get a universal LNBF that most people will
never fully use anyway. Now for those people that might be after
those few channels like CubaVision on PAS9 then by all means get
them and use them. But I think the folks that are just now getting
their feet wet in FTA satellite TV would be better served by not
getting a universal LNBF, picking up a standard LNBF with a 10750
Mhz LO frequency, and using the 22khz system in their receiver to
help them with their switching duties. For the noob it would help to
make LNBF switching a lot easier.

WHERE IS THIS INFO FROM?
THEY WILL MOVE TO OTHER SAT OR DISAPPEARED?
