		I initially operated RTTY using AFSK with a Rigblaster Nomic interface to an Icom IC-756 Pro transceiver.
		Using AFSK meant that I could not use the Icom's RTTY filters and QRM during contesting meant that I generally operated rather high in the RTTY sub-bands.
		Running FSK I was able at long last to use the Icom's RTTY filters (5 of them - 1 kHz, 500Hz, 350 Hz, 300 Hz and 250 Hz) along with the wonderful Twin APF filter which literally brought RTTY signals out of the noise.

	Getting Started on RTTY - Introduction
		RTTY is the most fun I've had in over 30 years of Amateur radio.
		Every program I know for RTTY includes special "buffers" which hold pre-typed messages that can be sent by pressing a function key or clicking a button on your screen with a mouse.
		RTTY is Baudot code (see http://chem.ch.huji.ac.il/~eugeniik/history/baudot.html for excellent information on Mr.

	Ham-Shack.com : Why RTTY?
		Following the band plans and operating RTTY only on the portions of the bands designated for that type of operation is a good idea.
		The three common speeds for 10 meter Baudot RTTY communications are 60 wpm (45 bauds), 75 wpm (56 bauds), and 100 wpm (75 bauds).
		Some RTTY operators have modified their transceivers to use the CW filter by adding a switch so it is possible to select the CW filter with the mode switch set for SSB operation.

	RTTY software, Digital mode ham radio - AMTOR, PSK31, AX25 ...
		With the "Reverse/Normal" button on Normal, "mark" is the higher RTTY tone; in Reverse "space" is the higher tone.
		The transmitter is left on and continuous sequence of "Letter shift" characters (in RTTY mode) or another idle characters is transmitted.
		Take into consideration that when you select RTTY or AMTOR mode via the "Mode" menu, speed and shift are reset to the default values 45 Baud/170 Hz and 100 Baud/170 Hz respectively.

	The Rochester DX Association - RTTY Rangers
		The purpose of the RTTY Rangers was to interest & activate more worthy RDXA members in digital contesting.
		Any station hearing a RTTY Ranger is requested to QRX, QSY or QRT until completion of their inevitable 599 contact.
		The HF RTTY sub-band boundaries are not written in stone. This is particularly true during RTTY contests. Below are approximations of "normal" operating RTTY sub-bands.

	RTTY Contesting
		RTTY SO2R operation is easier for the operator to pick-up and become proficient in than SO2R in the other modes.
		RTTY software must be compatible with the contest logging software you intend to use and vice versa.
		RTTY contest messages may seem long, e.g., “K4GMH TU 599 003 003(CR)” would be a typical response when the other station, who answered your CQ, is sending his report to you.

	ARRLWeb: PSK31--Has RTTY's Replacement Arrived?
		RTTY didn't have the error-free copy of the handshaking modes, and you certainly could not swap binary files using its limited code.
		When it comes to RTTY we're still dealing with binary data (dits and dahs, if you will), but instead of on/off keying, we send the information by shifting frequencies.
		Perhaps it is time for King RTTY to retire and yield to the heir apparent.

	Why RTTY is there is MFSK? - Digital Forum at eHam.net
		It does have wider bandwidth but not that much wider than RTTY that would make it a mode that is not worth running.
		I had a RTTY QSO with the Montenegro station and fading happened to be so bad during the 3 times he sent his name, I didn't get it.
		There does seem to be more DX on RTTY, lots of big guns too that are gimmees for small stations such as mine.

	Radioteletype - Wikipedia, the free encyclopedia
		RTTY uses a variety of different modulation methods, of which frequency shift keying is the most common.
		RTTY is extremely slow by modern standards; a typical baud rate for RTTY operation was 45 baud (approximately 60 words per minute).
		RTTY systems are also fielded by amateur radio operators, and are popular for long-distance contacts

		RTTY was first introduced to me in 1958-9.
		RTTY is a fun and easy mode to operate, but there are a few things, which may be puzzling to the newcomer.
		Roundtable discussions and nets, which would be difficult or slow with other modes, are a natural for RTTY, and RTTY is likely to be around for a long time to come.

		The link to his RTTY information page is http://www.aa5au.com/rtty.html All of his information is based on MMTTY.
		The advice about MMTTY is good advice, but make sure you get the entire stand-alone program, and not just the "engine" that allows the RTTY module to be used in the core of some other program.
		As stated, RTTY is usually operated on LSB no matter what band you are on, if for no other reason than to unify the frequency calibration.

	RTTY Modulator
		Ham radio operators have used RTTY (Radio TeleType) for years on the HF bands to send low-speed text data over the air.
		Conventionally RTTY is sent by changing the carrier frequency by 170Hz.
		The RTTY code uses two timers in the PIC to generate the bit timing and audio timing.

	RTTY info (Site not responding. Last check: )
		RTTY or RadioTeletype is a direct machine to machine communications mode using the Baudot (or Murray) code.
		This pattern is chosen as it produces the most frequent and almost symmetrical alternation of Mark and Space tones, giving the receiving operator the best chance to tune the receiver before the "real" message starts.
		It is quite possible to lose bits here and there when receiving a RTTY signal, whether it be because of fading, interference, frequency drift, or whatever.

		Win-Test uses the MMTTY engine by JE3HHT, so the first task, before you can start operating RTTY, is to go to the MMTTY home page, scroll down the page to where the title says "MMTTY Engine", download the ZIP file and unpack the file into a folder where you will be able to find it.
		Now you've selected "RTTY configuration" you will be shown a box similar to the one shown above; here you need to click "Run MMTTY" checkbox and add the path to the MMTTY application.

	RTTY Terminal
		This heavy-duty RTTY terminal unit was manufactured and distributed by Radio Wholesale in the 80's and early 90's.
		Originally they were mounted in gray Ten-Tec cabinets, but because most of the ham radio RTTY stations used Drake twins as stations, several "special order" units were manufactured and mounted in Drake R-4C cabinets to match those stations.
		RTTY Terminal Units are noted for reliability and were used in many commercial RTTY circuits over the years

		RTTY stands for "Radio Teletype" and is a method of sending Teletype text over amateur radio.
		Multiple collections are represented here, coming from different sources, but it must be made clear that this artwork is the result of hundreds of Hams around the world, transcribing already-existent typewriter art or creating new works by themselves, then transmitting them around.
		Some of these date back definitively to the 40s, with many of them showing up in the 60s, 70s and 80s and crossing over to Bulletin Board Systems, often with the credits stripped, and traded by BBS users who were often unaware of the years/decades of heritage the files had before the BBS was created.

	TR LOG - Support
		If all this works, you should be able to tune to an RTTY signal and see it in the TNC window.
		There are two aspects of RTTY that are different from CW, and affect how you program the memories.
		The first difference is that when there is no signal, the other station's TNC will probably convert random noise into random characters, or "garble." To separate your message clearly from the garble, it's a good idea to start and end your messages with a space or two, or even a carriage return.

		Even if you can't transmit (or you don't have a transmitter), you can use this gear to receive RTTY on the ham bands and other places where RTTY is used.
		RTTY doesn't need a lot of power, and your radio will last longer if you run it at 50% of full power.

		Using the TS-570 as the heart of the HF station, an old Pentium II computer running version 3.0.0 of DXLab's Winwarbler software, is used to drive an AEA PK-232 TNC.
		These files are used to configure the buttons that can be used to set the rig to transmit, send the contact info and then go back to receive.
		Although similar to the contest macros above, several of the buttons are used to call in text files, rather than be configured with lines and lines of text.

	RTTY Tuning Scope
		A 'scope is still the best way to tune a RTTY signal.
		Because the asynchronous codes used for RTTY always have more time at SPACE than at MARK, the vertical bar is brighter.
		Colors indicate the quality of the signal: the brightest color (white) indicates the strongest signals with green/blue/yellow indicating progressively less.
