[digitalradio] MT63 Operation
Lately I've been playing around with MT63 at the 500 hz bandwidth. It was just about the only digital mode that I had not experimented with since getting on the digital modes in 2003. I've made some contacts around 3584 kc and 14074 kc. The band plans that I see for 20 meters on the internet call for 14109 kc but I've seen no activity there or on any of other band The question is where most is the MT63 activity at? Or is there any? 73 GUD DX, Thomas F.

Re: [digitalradio] Re: A new Mode !
Just submitted this to Jose on his ROS blog page. What are your thoughts people please. Thanks for a quick reply Jose. There will be others who can recommend exact frequencies. I understand about not being swamped in the past lol, but the sub bands do kind of work. E.g. You'd never see an MT63 signal down at 14 075. I was thinking along the lines of just above the olivia 1000 frequencies. IE above the beacons and olivia but this may only give 1 spot frequency before you hit 14.112 14.101 14.112 is for unattended but is also used by olivia and winmor I think, there certainly wouldn't be any rtty in the way lol.

I am by no means an expert on band allocations hi hi could you mention this on the yahoo group too Jose and there will be some ideas for sure. Toby MM0TOB
[digitalradio] ROS band plan , and other modes
Avoid 14075-76 since this is where JT65A is on 20M. I like the idea of us all be around the same place with differing modes, that way, we can hear people calling and do not have to constantly twirl the dial. Since most people's waterfalls , including the one in ROS, are 3kHZ wide , and people's rigs often use an audio range of 3 Khz, I would like to suggest that ROS stay within 3 kHz of where everyone else is. Avoid the PSK31, JT65A, and usual RTTY ranges but have MFSK16, Hell, PSK63, ROS, Thor, Throbx, Olivia, Pax, ALE400, Dominoex and MT63 all in the same area. Close to PSK31 too, that way we can interest PSK31ers to try the odd sounding mode. I''d like to suggest we look at using this mode on WARC bands too On Fri, Feb 19, 2010 at 10:29 AM, Toby Burnett ruff...@hebrides.net wrote: Just submitted this to Jose on his ROS blog page.

Re: [digitalradio] Re: A new Mode !
Hi Glenn, yes the band wasn't there and I have a faulty power line pole that they refuse to fix, it's about 200m from the qth and splatters S8 on 20m until it rains, (then all quiet and I can hear a pin drop in the south pacific lol I WISH) Well it occurred that this mode 2250hz wide is a little big to play in between the rtty, olivia 500, ale etc I see Andy has an idea too and I can see your point to Andy. I just think at 080 we will all get stomped on. I notice another chap asking about the old 109 MT63 frequency which is kind of where I was going as I haven't seen any mt63 for ages. Andy I understand the wanting to keep it all close together etc but I cant see how well it'd work. If we could make an unofficial experimental mode slot ?? Keep the suggestions coming though.

As with all transmissions, you should listen before transmitting to make sure you are not clobbering someone else. However, it seems that courtesy isn't always given at times as I hear/see various modes and people transmitting on top of each other and, at times, even people using the same mode transmitting right on top of others.

Gary wrote: How do I select a specific sound card? Some of us are using external USB sound card devices for digital operation. At present it uses the Windows default soundcard, although this may change in future releases. So, you will need to open Control Panel, then open Sounds and Audio Devices and click on the Audio tab. There you will find a pair of drop down menus called Sound playback and Sound recording. Select the card you want to use, click Apply and close Sounds and Audio Devices and run RIO again. Now it should be using the sound card you selected. Personally I'm not keen on this system but the author (Sorry, I've not latched onto the authors name and I guess it was mentioned in an early post and I didn't pick up on it) did post a message here, when he uploaded V1.6.2 with the COM port additions, that selectable sound cards would come in a later release.

Re: [digitalradio] Re: ROS, legal in USA?
All, If we accept the fact that a SSB transmitter with sufficient carrier suppression simply generates an RF carrier equal to the suppressed carrier frequency plus the tone frequency (USB), then frequency hopping is frequency hopping (spread spectrum), regardless of how the carriers are generated. That is really too bad for US hams as all morning I have been receiving alerts and printouts from many stations on 14.080 - many times when the ROS signal can hardly be heard above the noise. I'm afraid that Andy's concerns are real, and unless the FCC clarifies otherwise, ROS is currently illegal in the US in my personal opinion and interpretation of the FCC rules. However, it looks like a worthwhile mode to test on UHF (432 MHz) where SS is allowed and we will be doing that during our daily digital experiments every morning on 432.090 SSB. The Doppler shift, multipath distortion, and fast flutter, as well as QSB often as deep as 15 dB, often make even S3 phone signals unintelligible. We have been also been testing extensively with DominoEx 4 on FM (DominoEX does not survive Doppler shift well on SSB) and Olivia 16-500 and 4-500 on both FM and SSB, often with better copy than with SSB phone, and especially so when signals are near the noise threshold. The path length is 200 miles, so signals are usually near the noise threshold during these winter months where there is no propagation enhancement. I'll post the results of our tests on 432 MHz here during the next two weeks as we compare ROS to Olivia. So far, plain old CW can be copied when even Olivia cannot, but the CW note is very raspy sounding, much like it is during aroura communication. It would help a lot if it were possible to select alternate soundcards and many of us on UHF and VHF are using a second soundcard for digital operations. 73 - Skip KH6TY nietorosdj wrote: One comment: It is not the same a Spread Spectrum Transceiver (like military radios) that to send digital data into an audio channel on standard SSB transceiver.

Re: [digitalradio] ROS, legal in USA?
Unfortunately, the ROS explanation of Spread Spectrum and Frequency Hopping in the documentation too closely resembles the definition of Spread Spectrum as written in the Wikipedia http://en.wikipedia.org/wiki/Spread_spectrum. Since ROS claims to be Frequency Hopping and Spread Spectrum by its own documentation, it is, no matter what you want to call it. The FCC recently clarified what a repeater is because a group insisted that any time delay meant it was not actually repeating, but their argument lost. There is good reason to want the FCC to allow ROS to be used in the automatic subbands, but that will take time and a petition.

Re: [digitalradio] Re: ROS, legal in USA?
The difference is the use of Frequency Hopping. In Olivia and the other digital modes, frequency hopping is not used but the data is sent redundantly over the width of the signal - MT63 is a good example. From the ROS documentation: ROS uses a Spread Spectrum technique known as Frequency-hopping spread spectrum (FHSS). In a conventional 16FSK system, the data symbols modulates a fixed frequency carrier; but in a FH/16FSK system, the data symbols modulates a carrier whose frequency pseudorandomly determined. In either case, a single tone is transmitted. ROS modulation scheme can be thought of as a two-step modulation process -- data modulation and frequency hopping modulation---even thought it can be implemented as a single step whereby the frequency synthesizer produces a transmission tone based on the simultaneous dictates of the PN code and the data. At each frequency hop time a PN generator feeds the frequency synthesizer a frequency word (a sequence of l chips) which dictates one of 2^l symbol-set positions. The frequency hopping bandwidth, and the minimum frequency space between consecutive hops positions, dictate the minimum number of chips necessary in the frequency word. I think the FCC rules are more concerned with the encryption aspect of Frequency Hopping than with the spreading bandwidth, but ROS can be copied by anyone with the ROS software, so there is a good chance the FCC might allow ROS on HF in the US, but as it stands right now, the definition of the ROS modulation scheme classifies it as Spread Spectrum and Frequency Hopping, and the ROS documentation agrees with the FCC. :-( 73 - Skip KH6TY Dave Ackrill wrote: KH6TY wrote: All, If we accept the fact that a SSB transmitter with sufficient carrier suppression simply generates an RF carrier equal to the suppressed carrier frequency plus the tone frequency (USB), then frequency hopping is frequency hopping (spread spectrum), regardless of how the carriers are generated.

Re: [digitalradio] Re: ROS, legal in USA?
I agree. Spread spectrum is illegal below 420 MHz in the U.S. and the ROS documentation describes a spread-spectrum system. It's certainly no wider than modes that use Walsh codes or low-rate convolutional codes but these systems increase bandwidth by increasing redundancy and are therefore legal. ROS is another good reason for regulation by bandwidth instead of the overly restrictive system in the current FCC regulations. 73, John KD6OZH - Original Message - From: KH6TY To: digitalradio@yahoogroups.com Sent: Friday, February 19, 2010 18:19 UTC Subject: Re: [digitalradio] Re: ROS, legal in USA?

The term Spread Spectrum can apply to any mode that spreads its energy over more than the necessary bandwidth. If we assume the necessary bandwidth to be equal to the signalling rate than anything other than single carrier modes technically fall into this category. Even WSPR coul dbe considered spread spectrum! Its 6Hz bandwidth is wider than the 1.5 B/s rate. Within the WSJT suite, JT65 is more of a spread spectrum mode, and outside Joe's suite, MT63 with its 2.5kHz for a few tens of Bits / second is even more extreme. Andy www.g4jnt.com

Hello to all, I found this on the ARRL Site: QST de W1AW ARRL Bulletin 62 ARLB062 From ARRL Headquarters Newington CT September 9, 1999 To all radio amateurs SB QST ARL ARLB062 ARLB062 FCC relaxes rules for spread spectrum The FCC has relaxed rules governing the use of spread spectrum techniques by radio amateurs and opened the door to the possibility of international spread spectrum communication. The Report and Order in WT Docket 97-12 adopted August 31 concludes a proceeding that originated with an ARRL petition in December 1995 and has been pending since 1997. The FCC adopted rules that will allow Amateur Radio stations to transmit additional spread spectrum emission types. Once the new rules become effective November 1, hams will be able to use techniques other than frequency hopping and direct sequence spreading. In addition, the new FCC rules will permit US hams to use spread spectrum techniques to communicate with amateurs in other countries that permit SS. Spread spectrum communication has been limited to stations within FCC jurisdiction. The new rules require that spread spectrum stations running more than 1 W incorporate automatic transmitter power control. Amateur stations using SS are restricted to a maximum power of 100 W. The Commission also amended the rules to eliminate what it called ''now-unnecessary record keeping and station identification requirements'' that apply only to stations using spread spectrum. The FCC agreed to let SS stations identify themselves using conventions developed by the Amateur Radio community. Roanoke Division Vice Director Dennis Bodson, W4PWF, who has followed the League's Spread Spectrum initiative through from start to finish was pleased with the outcome of the proceeding. ''I'm very happy,'' he said. ''The League got everything it wanted and more--all of which, I believe, will help to promote this mode on the amateur bands.'' Stations employing spread spectrum techniques will remain secondary to--and must accept all interference from--stations employing other authorized modes.

Re: [digitalradio] Re: ROS, legal in USA?
It's my interpretation of the U.S. Code of Federal Regulations, Title 47, Part 97. You can see the authorized emissions table at 97.305 and the definition of SS (spread spectrum) at 97.3(c)(8). You can acces a copy via the FCC web site at www.fcc.gov. FCC rules are much more restrictive than those of any other country that I have seen. A few years ago, the ARRL proposed changes (which I supported) that would have changed the regulations to limit bandwidth rather than emission type but their members rejected the idea and they withdrew the petition. 73, John KD6OZH - Original Message - From: jose alberto nieto ros To: digitalradio@yahoogroups.com Sent: Friday, February 19, 2010 19:30 UTC Subject: Re: [digitalradio] Re: ROS, legal in USA?

Re: [digitalradio] (unknown)
The FCC specificly allows multiple-subcarrier transmissions on HF but bans spead spectrum emissions using bandwidth-expansion modulation. Multiple-subcarrier modes don't have to increase the bandwidth as the signal is split into N parallel streams and each can occupy 1/N the bandwidth of the original. 73, John KD6OZH - Original Message - From: AC TALBOT To: digitalradio@yahoogroups.com Sent: Friday, February 19, 2010 19:18 UTC Subject: [digitalradio] (unknown) The term Spread Spectrum can apply to any mode that spreads its energy over more than the necessary bandwidth.

[digitalradio] RTTY and mode selection on radios
Wondering if someone can point me to a link or some literature explaining about why there is a FSK mode on the HF radios like the Icom ic-746pro, Kenwood TS0940sat, and Ten-tec Paragon (585)? Is there a reason for this? I am asking this because I have listened to some RTTY using either USB or LSB dependent on what band I am on and could copy it with any software programs I have but then switched to the FSKmode on the radios and loose the signal completely. Is this mode just for the older ancient RTTY eqiupment to interface with the radio?

Re: [digitalradio] RTTY and mode selection on radios
FSK is RTTY but so is AFSK. Some rigs support the use of RTTY in FSK while others require a TNC or sound card to generate the tones. FSK on transceivers tends to invoke narrower filters and the frequency you are receiving is displayed differently. The serious RTTY guys tend to prefer FSK. This post from the N1MM Logger reflector illusrates some issues.. (see also http://www.mcwa.org/AFSKvsFSK.pdf) Doug Haft wrote: Are you running AFSK, or FSK? Does this mismatch in frequency happen on every spot, or randomly? If AFSK, which sideband, LSB or USB? I haven't thought this trough, so I might be off base here, but its possible the spotter is running AFSK. So, their rig is in USB (or LSB). Their audio tones will be up (or down if using LSB) in the sideband. The freq on their rig will be offset from where the tones really are. If you're running FSK, you'll tune to the freq they spotted, but the target station won't be there! Worse yet, if you're in USB running AFSK and the spotting station is in LSB AFSK... the spot he puts out will be quite a ways from where you land as a result of clicking that spot.

Jose, We want to be able to use the mode on HF, but it is not our decision, but our FCC's decision, for whatever reasons they currently think are valid.

All, If we accept the fact that a SSB transmitter with sufficient carrier suppression simply generates an RF carrier equal to the suppressed carrier frequency plus the tone frequency (USB), then frequency hopping is frequency hopping (spread spectrum), regardless of how the carriers are generated. That is really too bad for US hams as all morning I have been receiving alerts and printouts from many stations on 14.080 - many times when the ROS signal can hardly be heard above the noise. I'm afraid that Andy's concerns are real, and unless the FCC clarifies otherwise, ROS is currently illegal in the US in my personal opinion and interpretation of the FCC rules. However, it looks like a worthwhile mode to test on UHF (432 MHz) where SS is allowed and we will be doing that during our daily digital experiments every morning on 432.090 SSB. The Doppler shift, multipath distortion, and fast flutter, as well as QSB often as deep as 15 dB, often make even S3 phone signals unintelligible. We have been also been testing extensively with DominoEx 4 on FM (DominoEX does not survive Doppler shift well on SSB) and Olivia 16-500 and 4-500 on both FM and SSB, often with better copy than with SSB phone, and especially so when signals are near the noise threshold. The path length is 200 miles, so signals are usually near the noise threshold during these winter months where there is no propagation enhancement. I'll post the results of our tests on 432 MHz here during the next two weeks as we compare ROS to Olivia. So far, plain old CW can be copied when even Olivia cannot, but the CW note is very raspy sounding, much like it is during aroura communication. It would help a lot if it were possible to select alternate soundcards and many of us on UHF and VHF are using a second soundcard for digital operations. 73 - Skip KH6TY nietorosdj wrote: One comment: It is not the same a Spread Spectrum Transceiver (like military radios) that to send digital data into an audio channel on standard SSB transceiver.

Re: [digitalradio] Re: ROS, legal in USA?
We want to be able to use the mode on HF, but it is not our decision, but our FCC's decision, for whatever reasons they currently think are valid. Fortunately, it may work well on VHF and HF, so I plan to find out. Might this give some wider data on UHF? 20KHz? 50 KHz? Would it be limited by more then the soundcard and RF platform?

Re: [digitalradio] Re: ROS, legal in USA?
Jose (and all), My two-cents worth: Olivia is MFSK (or AMFSK), ROS is Spread Spectrum. MFSK is legal on HF, SS is not. It isn't about bandwidth or any of the other arguments. Since ROS is Spread Spectrum then it is not allowed on HF in areas regulated by the FCC under the current rules. Skip is correct here and Andy is right to be concerned.

Is there a reason for this? I am asking this because I have listened to some RTTY using either USB or LSB dependent on what band I am on and could copy it with any software programs I have but then switched to the FSKmode on the radios and loose the signal completely. Is this mode just for the older ancient RTTY eqiupment to interface with the radio? I haven't tried to send any RTTY yet but planning to be on the air next weekend for the NAQP RTTY contest from the Red Cross station in Ann Arbor,MI. James W8ISS RTTY should not be referred to as afsk even if audio is fed into a ssb radio. What comes out of the transmitter is the same if true FSK or AFSK is used. Whoever started that wording should be shot. It is AFSK if AM or FM is used. For the ham bands rtty should be received and transmitted in the LSB mode on all bands if ssb is used.YOu can set the tones up in reverse and use usb, but it is not recommended. When you switch from lsb to the rtty mode, most receivers will shift up or down 2125 hz if you have it set up correctly. That is what the mark tone should be. Actually any two tones can be fed into a ssb transmitter as long as they are 170 hz apart. The lowest tone should be around 1500 hz or so as the second harmonic of it will be out of the pass band of the filter. The station on the other end will not know the differance, just your dial frequency will not match his. RTTY was origionally sent on the low bands by shifting the frequency of the transmitter lower in frequency when the space was sent. When ssb transceivers came into use it was found that if you put a pure sine wave into the microphone input you generated just a single output frequency. If that audio tone was changed a small ammout the frequency of the output would change the same ammount. If usb is used the frequency would shift up and if lsb was used the frequency would shift down. LSB is used to keep everything the same weather the shift was the actual carrier or if audio tones are used. You have to have a good understanding of how a single frequency fed into a ssb transceiver will change the output frequency to understand rtty.

[digitalradio] Re: MT63 Operation
We use MT63 on our wpaNBEMS nets here in Western PA on 3.5835 USB, 1000hz center on the waterfall. Our nets start out on 8/500 Olivia then we transmit a 1000hz MT63 1k long (64 bit) interleave bulletin. We stay on MT63 1k long and then go for comments since we're in the faster mode. We have been using MT63 2k long on 2m and 70cm FM now for about 5 years. Many of our net participants send and receive messages on fm simplex and over repeater using nothing more than a laptop and hand held (no direct interface). It works amazingly well and will let you send about 1k per minute (repeater timeouts get you right around the 3k mark). We send detailed messages and spreadsheets using NBEMS/FLDIGI and WRAP (checksum) which allows us to transmit a bulletin and have an unlimited number of stations simultaneosly receive and confirm 100%. Other than the local stuff on 80m and VHF/UHF, I've not seen much in the way of DX'ing with MT63. -Dave, KB3FXI www.wpaNBEMS.org --- In digitalradio@yahoogroups.com, Thomas F.

Re: [digitalradio] RTTY and mode selection on radios
RTTY should be used in the LSB mode regardless of the band. I don't use software for RTTY so I cant tell you a thing about that.
[digitalradio] Re: RTTY and mode selection on radios
If the radio has RTTY as a mode, as does the TS-940 for example, it means (1) there is an input on the back where you put in a baseband signal and FSK comes out the antenna, and (2) for receiving it will use a narrow filter and center the filter up around 2.2 KHz. (By baseband I mean the actualy RTTY signal at 45.45 baud, as would come out of a Teletype keyboard.) In the case of the TS-940 and other radios there is a misfeature that in SSB mode you can't get the narrow filter switched in; you have to use RTTY or CW mode to get the narrow filter. The main reason you want the narrow filter is to suppress strong signals that are in the IF passband of the radio but not in the middle of the signal you are trying to receive. Such signals will affect the gain of the receiver through AGC action, so that the level of the desired signal goes up and down as those off-channel signals come and go. So you want the narrow filter to have the AGC focus on the signal you are trying to receive. The reason the receiver puts the filter up at 2.2 KHz in the FSK mode is that in olden days FSK signals were translated to audio, originally at 2125 and 2975 Hz, later changed to 2125 and 2295 when 170 Hz shift came into use. So if you were using a typical RTTY terminal unit for receiving its input frequency range would be up there. Jim W6JVE
[digitalradio] FCC Spread Spectrum
3. Spread spectrum is a technique whereby the energy of the transmitted signal is distributed over a wide segment of spectrum. The signal power density can be very low and the duration of a transmission on any frequency in the segment of the spectrum can be but a fraction of a second. SS systems, therefore, can evenly share all of the spectrum in the available frequency segment, despite a number of stations transmitting simultaneously. They can often share the same spectrum unobtrusively with non-SS systems because the transmissions may not be noticeable to a casual listener. 4. Special Temporary Authority to experiment with SS transmissions was granted to 25 amateur stations affiliated with the Amateur Radio Research and Development Corporation 16 years ago. These experiments involved on-air evaluation of different spreading rates, frequency ranges, and interference to stations transmitting other emission types. On the basis of these tests, two types of spreading techniques -- frequency hopping and direct sequence -- were authorized by our rules. Under our current rules, SS transmissions may be made on authorized amateur service frequencies above 420 MHz with transmitter powers up to 100 watts. Since introduction of SS in the amateur radio service, numerous commercial applications of SS have also evolved, including personal communications services, remote meter reading and position locating.

[digitalradio] Polarized Rotation Modulation (PRZM)
From Darpa: Polarization modulation introduces an additional dimension. A radio with four polarization possibilities would transmit four times the information with all other aspects of the waveform held constant. http://www.darpa.mil/sto/strategic/pzrm.html Sounds interesting. Robert

Dave (G0DJA) Well, as a G0 its perfectly acceptable that you don't know. The K's N's W's and A's have no such excuse. Lets check out 47CFR2.201 and see what type of signal ROS is. The first letter is modulation. Clearly its F Frequency modulated. I read the ROS PDF and its basically a 16FSK that has its carrier frequency modulated/wiggled in a peculiar pattern. The number is nature of signal(s) modulating the main carrier. Clearly its 2, A single channel containing quantized or digital information with the use of a modulating sub-carrier, excluding time-division multiplex. That sub-carrier is the 16FSK, which thankfully (?) isn't TDM data. The second letter is type of information to be transmitted. Well, obviously that is D for data. We're not sending E voice or A telegraph or whatever here. So, the overall FCC Emission designator would pretty obviously be F2D. Where can we run F2D? First, hit FCC 97.305(c) authorized emission types table. The FCC says SS only on 222 and up. I have no idea what inspires people to publically claim you can only run SS on 432 and up, as 97.305(c) explicitly permits it on 222 and up. For another example, on 30M we can do RTTY or DATA. How does DATA or RTTY or SS or PULSE relate to emissions designators? The FCC helpfully defines that in 97.3(c) To qualify as SS all it needs per 97.3(c)(8) is Spread-spectrum emissions using bandwidth-expansion modulation emissions having designators with A, C, D, F, G, H, J or R as the first symbol; X as the second symbol; X as the third symbol. F2D doesn't seem to match the def of SS. To qualify as DATA all it needs per 97.3(c)(2) is Telemetry, telecommand and computer communications emissions having (i) designators with A, C, D, F, G, H, J or R as the first symbol, 1 as the second symbol, and D as the third symbol; (ii) emission J2D; and (iii) emissions A1C, F1C, F2C, J2C, and J3C having an occupied bandwidth of 500 Hz or less when transmitted on an amateur service frequency below 30 MHz. Only a digital code of a type specifically authorized in this part may be transmitted. F2D doesn't seem to match the def of DATA. Looks like USA folks can't transmit ROS at all, on any band. Ooops. Will people fooling around with ROS get dragged to court? Probably not. See 97.305(b) A station may transmit a test emission on any frequency authorized to the control operator for brief periods for experimental purposes, except that ... (essentially no SS or pulse where not otherwise permitted). So, fooling around for testing and experimentation of a new mode is well within the law by this exception. Running a contest, a regular schedule, a formal net, DXing, QSL card collecting, county hunting, or extensive ragchewing would be strictly verboten under 97.305(b). The key is doing it in a documented manner as an experiment, like as a research experiment or an article for QEX. Realize that big brother can deprive you of your life and liberty at any time for any reason, its not as if a rule prevents that, it just claims Big Bro won't do it, and politicians never lie... In summary, the problem seems to be FM modulating the carrier of the 16FSK. 73 de Vince N9NFB

[digitalradio] Buglet in ROS
A minor but annoying problem I'm having is that in Windows XP it keeps maximizing the window without being told to. I haven't found for sure what triggers it, but just now I am monitoring and a ROS signal came on and a second or two after the initial tone the window maximized itself. Yup, just happened again, started receiving and about 1 second into the transmission it maximized the window. Jim W6JVE
