	Pactor Primer
		The Pactor controllers all come with thick manuals which cover a multitude of operating modes, but by the time you painfully extract the part that is relevant to Pactor you find the documentation to be pretty thin.
		Pactor is a method of sending digital information via radio, and was developed around 1990 by a small group of German hams who formed the company SCS.
		The first Pactor controller was developed by SCS and the protocol was adopted by most other manufacturers of TNC's (Terminal Node Controllers, or radio modems), but often without the analog memory error correction scheme developed by SCS.

	Pactor Protocol Description
		PACTOR (PT), specially designed for operation in noisy and fluctuating channels, is an improved half-duplex synchronous ARQ system combining the reliability of PR with the fixed AMTOR time frame.
		The standard cycle duration does not differ from FSK PACTOR and is still 1.25 seconds, which is one of the requirements to obtain easy compatibility to Level I. Longer Control Signals (CS) had to be applied to achieve a higher robustness for the acknowledgment signal, required due to the greater robustness of the data channel.
		As the pactor level increases, the relative performance increases with Pactor-3 being far superior to any mode ever developed for the HF spectrum.

	RE: PACTOR on the birds
		I don't think that PACTOR is 100% duty cycle.
		The technical one is that pactor is not dopler tolerant, the tolerace for pactor 1 is less then 80 hz, I think pactor 2 and 3 are even more critical.
		The operational problem is that it is very bad practice to use a 100% dutycycle mode on most linear sats, some will alow psk31 sstv and other modes but most don´t.

	PACTOR
		PACTOR can be viewed as a combination of two earlier digital modes, packet radio and AMateur Teleprinting Over Radio (AMTOR).
		PACTOR provides improved throughput because its transmission speed adapts to the quality of the link and it uses Huffman compressed characters.
		PACTOR is a synchronous transmission system with a packet duration of 0.96 second, a CS duration of 0.12 second, and an idle time of 0.17 second for a total cycle time of 1.25 seconds.

	What is pactor III?
		PACTOR III is the next generation HF data transmission mode developed by SCS of Hanau Germany.
		PACTOR I and II modes are supported by PTC-II, PTC-IIe and PTC-IIpro modems manufactured by SCS.
		PACTOR III uses a voice channel of 2.4khz and with an optimal link, is 4 to 5 times faster than PACTOR II mode.

	pactor
		Pactor is one of the digital modes which radio amateurs are permitted to use.
		Inbuilt in the pactor protocols are two speeds with automatic change up and down to suit the conditions, checksum error correction (similar to packet radio protocols), and data compression.
		Pactor sessions can include keyboard to keyboard contact, access to BBS in Australia or overseas and reliable BBS forwarding over long distances.

	Repeal Part 97.221(c)
		Pactor mailbox stations are randomly spread all over the 20 meter band from 14060 kHz to 14120 kHz, instead of being clustered in one place so they can be avoided.
		If mobile Pactor mailbox stations are going to operate just as automatic stations do, not listening before transmitting on a frequency, and they universally do, then they must be forced to use the sub-bands set aside by the FCC for communication between two automatically controlled digital stations.
		Pactor mailbox services, such as those provided by WinLink 2000 and others, are extremely valuable to a few thousand out of hundreds of thousands of hams in the world, and should be preserved, but not by operating outside the rules all other hams must follow and not by creating excessive interference to other modes.

		Email-Communication via Pactor is not only a cheap and easy solution for scientific expeditions, cruising folks on sailboats or the enthusiastic HAM radio operator.
		PACTOR® (lat.: the mediator) is a fast and reliable ARQ teletype mode, developed by Hans-Peter Helfert (DL6MAA) and Ulrich Strate (DF4KV) to overcome the shortcomings of AMTOR/SITOR and Packet Radio on short wave.
		Email communication via Pactor can mean the cord to civilization for many people in third world countries.Nzola realized this possible solution and founded the society REMCU, who provides help for remote villages in Africa.

	PACTOR II
		PACTOR II PACTOR-II is a fully backward-compatible improvement to the original PACTOR system.
		As in PACTOR, CS1 and CS2 are used to acknowledge/request packets and CS3 forces a break-in.
		PACTOR II uses different forms of two-tone DPSK modulation in all of its modes and starts using DBPSK modulation at a data rate of 200 bit/s with rate 1/2 coding to provide a throughput of 100 bit/s.

		So Pactor is the protocol, or language, while the terms TNC, radio modem, or pactor modem refer to a piece of equipment.
		This clever name is actually a direct reference to the sophisticated methods the Pactor protocol employs to set up and manage a digital radio connection between, say, your boat and a land-based service provider - all the while keeping the connection humming at the highest speed achievable under the circumstances.
		Pactor, the protocol, traces it's roots to the late 1980's and efforts by a couple of German amateur radio operators to improve digital radio communications.

		Pactor II Pactor II is DSP based and is as much as 8 times faster then Pactor I. A Pactor Level II signal features 2 tones w/200Hz shift using baud rates of 100 or 200 fitting into a 500Hz channel.
		Pactor II is a half-duplex synchronous ARQ system and designed to be backward compatible with the older Pactor Level I protocol.
		Pactor Level II is operational in Europe and is in the manufacturing stage in the US.

	iB::Topic::Pactor QRM vs Contest QRM
		The problem with Pactor robots is that they are unattended stations, not run by humans so they just come up in the middle of the band without asking.
		Essentially the problem is that Pactor, like packet, apparently uses a simple DCD controlled by SQUELCH to determine whether a frequency is being used.
		But the Pactor stations don't seem to do that and haven't shown much interest in "playing nicely." And as already mentioned, many who use them could care less, as long as they get their email.

		PACTOR mailbox operators have a right to use the same frequencies everyone else uses, but they are required by the FCC to listen first for activity on the frequency before transmitting, just like everyone else must do.
		The number of times PACTOR stations override PSK31, PSK63, or CW communications is so great that the probability is that they seldom, if ever, "listen first" in their passion to use the ham bands as an automatic gateway to send and receive email to and from the Internet.
		If the PACTOR signal is merely adjacent to your QSO partner's signal on the waterfall, it may be affecting the AGC of your receiver, the effect of which can sometimes be reduced with passband tuning, IF shift, or a more narrow filter, but it is not considered interference, and should not be reported as such.

		If you are using Pactor III your connection will probably not be interrupted, although it might slow down some.
		Pactor III is a new "Pactor" protocol that uses 2400Hz bandwidth, as opposed to the 350 Hz of Pactor II, and can transfer data 3-4x faster than Pactor II in good conditions, and slightly faster than Pactor-II in weak signal conditions.
		Pactor III sounds like periodic "rasping." As always, listen and make sure that a SailMail frequency is not in use before you connect.
