[digitalradio] NBEMS/FLDIGI/FLWRAP/FLMSG (ICS-213 ARRL Radiogram)
Hello all,
I just wanted to drop an example of our digital net traffic here using
NBEMS/FLDIGI software.
Skeds and info at www.wpaNBEMS.org. Modes used are Olivia 8/500 for keyboard to
keyboard and short messages such as NTS and MT63 1k Long Interleave for spread
sheets, bulletins, book traffic and other more detailed messages.
FLMSG is a help app that handles ICS-213 and ARRL Radiogram. This is in alpha
testing and is working fantastic. FLMSG is avialable at www.w1hkj.com/alpha
-Dave, KB3FXI
Here's the text from our net this morning. This is unedited with the exception
of me removing Diddle.
You'll notice that the majority of the messages were copied 100%. This is
confirmed 100% with a feature called flwrap.exe that uses an embedded checksum
calculation. WRAP is unique in the digital sound card realm in that a single
transmission can be received and confirmed by an unlimited number of stations.
And unlike ARQ modes, ALL stations within propagation have the benifit of
monitoring the traffic even if they don't have FLWRAP!
##
cq cq cq... calling wpaNBEMS
this is a directed net. please wait for your call.
stations needing to break in on the net with emergency
or priority traffic should transmit a 3 second tune/tone
signal at the center of this waterfall frequency.
relays, please indicate so with a 1 sec tune/tone signal.
is there any emergency or priority traffic. if so, please call

[digitalradio] NBEMS Digital EmComm Messaging System Featured in August QST [1 Attachment]
There is an interesting article in August QST, pages 73 - 74, about the NBEMS (Narrow Band Emergency Messaging System) software. NBEMS can be used to transmit bulletins binary files using the MT63 digital data mode over FM simplex or repeaters using accoustical coupling. There is no need for a sound-card, TNC, external modem, radio computer interfacing, modified radios or dedicated digital radios / infrastructure. Dave, KB3FXI Harry, W3YJ, ARRL Assistant SEC, Western Penn. section are featured in the aritcle.They have experience using NBEMS and have a group, www.wpanbems.org that uses NBEMS with MT63 Olivia. Last winter Dave Harry held a webinar about NBEMS. I've attached a copy of the NBEMS webinar presentation. Dave should also be able to forward a copy to you. More information about NBEMS capability is available at: www.w1hkj.com Additionlly, there is Yahoo group, NBEMSham, focusing on NBEMS available at: http://groups.yahoo.com/group/NBEMSham/ It's an interesting technology that seems very easy to use may have some application, especially on a local basis. 73, Mark, WB9QZB Chicago, IL
[digitalradio] NBEMS software problems
Sorry for the tardy reply but I only receive a daily synopsis from this group. If you need help with any aspect of running the NBEMS suite (fldigi, flarq, wrap) you will receive a more timely response by posting your questions and problems on the yahoo group dedicated to it's support: nbems...@yahoo.com You should be prepared to enumerate what version of each of the programs you are testing and what hardware you are using for the test. You will probably be asked to provide further information regarding the type of transceiver control being used on both ends of the qso. The person assisting will also ask for the timing settings and what mode you are using for the flarq tests. If you have programming skills that complement your operating skills you have the opportunity to contribute to making any or all of these programs better for yourself and the amateur radio community as a whole. All of the NBEMS programs are General Public License (GPL). That means the source code is ALWAYS available to you. Contributing in this way is far more noble than simply grousing about failures that may or may not be attributed to the software. Binary and/or executable files are simply a convenience for those who are not able to build the application from source. Some mention was made about receiving an OS message during program startup. I have only seen the message on VISTA and it is almost always associated with a change in h/w between a shutdown and subsequent restart of fldigi. Did you unplug either your microphone, line-in, or speaker out from your sound card? If you did then VISTA reports that the sound system is not available. Fldigi is trying to access the sound system and fails (at the OS level) to do so. There is probably a way to avoid this problem, but the Linux programmers who work on fldigi are not aware of how to do so. Here is an opportunity for a Microsoft skilled programmer to lend a hand (see para above). 73, Dave, W1HKJ

NBEMS - Narrow Band Emergency Messaging System Is anyone familiar with this mode? What type of equipment is needed? I have an MFJ-1250C. Will this work with this or will I need a different type of interface? Thanks! Rod KC7CJO
Re: [digitalradio] NBEMS
Hi Rod, The NBEMS setup uses soundcard technology. Although the TNC will provide you with packet capabilities (which can be important depending on where you are and what's available in your area), the NBEMS technology relies on various soundcard-based modes and doesn't use hardware based packet at all AFAICR. Keep your TNC in case you want to run Airmail, but also setup a soundcard interface to use the NBEMS software and modes. Also, you might want to look at the Paclink software which will work better with your TNC than Airmail will. 73, Jeff Moore -- KE7ACY DCARES - Deschutes County ARES - Original Message - From: Rodney Subject: [digitalradio] NBEMS NBEMS - Narrow Band Emergency Messaging System Is anyone familiar with this mode?

Re: [digitalradio] NBEMS
I used THOR 11 and 22 on mars nets didn't really take off though as no body had the software, supposed to be better than MFSK 16 as its a IFSK. NBEMS modes with the high speed digital with ARQ are more for VHF UHF handshaking. Any soundcard interface should work, good thing to have in your tool box is the highspeed digital and data ARQ for VHF emcomm and with flidigi software you dont need a external piece of hardware for the ARQ.

Re: [digitalradio] NBEMS
The County EOC will have an ARES unit attached to it. Each city within that County will have an ARES unit assigned to it, provided there are enough hams in that area, otherwise they are broken down into sections. Each section, or ARES unit, will have a set of frequencies assigned to them in the HF, VHF, UHF bands. Again, the modes used on these bands are set up, depending on what the ARES unit personnel are set up to use. As for the ARRL, I don't think there's an Official band segment designation for this particular mode, besides, during an emergency, all bets are off and you can and will use any means necessary to get communications through. NBEMS - Narrow Band Emergency Messaging System is just what it means, an Emergency Messaging system! Most likely it's only going to be used during emergencies. Being a former AEC or our local city ARES unit, we employed Ham, CB, FRS, MURS, cell phones... to get the job done and it all worked with relatively few issues! As long as the ARES, CERT, and RACES personnel are properly trained, things usually go off without any major hitches.

[digitalradio] NBEMS QST article/digital weak signal FM
There was a very nice comment in Steve Ford's Electic Technology column about NBEMS. He mentions that it is a suite of Windows sound card programs allowing ARQ exchanges of messages, but one of the compelling features of fldigi and flarq which make up the suite of programs, is that they work cross platform. No other software of this type has this capability to work with Windows XP, Vista, Mac, Linux and Free BSD. The impression seemed to be that fldigi can work with Windows and Linux. A really important point was that Skip, KH6TY, found it possible to use DominoEX modes with FM modulation and work farther than SSB phone. That is a very significant new finding. Anyone else having luck with that? What about other modes with FM? Would it also be true that DominoEX (and other modes) would work even farther with SSB digital vs FM digital? Even though horizontal polarization was emphasized, the fact is that hams with FM only rigs do not have horizontal antennas and vertical to vertical should work very well, even if there may be a slight edge to horizontal. Has anyone else been able to do any comparisons between H to H and V to V on FM? 73, Rick, KV9U

Yes, fldigi is a cross-platform program and works on both Windows and Linux, etc. A really important point was that Skip, KH6TY, found it possible to use DominoEX modes with FM modulation and work farther than SSB phone. That is a very significant new finding. Anyone else having luck with that? What about other modes with FM? DominoEx has been found to be more successful than either PSK31 or MFSK16 (the two most popular high sensitivity modes), and for QSO's and contest exchanges, DominoEX 4 is still fast enough (but too slow for messaging) at 25 wpm, and works the best of all when you are far under limiting and with poor S/N. DominoEX is not as critical to tune and more resistant to multipath interference than PSK31, so I think it will be the mode of choice for FM DX, outperforming both PSK31 and MFSK16 when the S/N is very poor, as will always be the case for the weakest stations. Would it also be true that DominoEX (and other modes) would work even farther with SSB digital vs FM digital? Yes, the advantage of SSB over FM we find to be around 3-4 dB or more. However, CW works as well as DominoEx 4, and going to CW is already customary in the weak signal community when SSB phone cannot make it. When propagation is poor, you will sometimes find stations calling CQ in CW on the phone calling frequency (144.2 MHz), and then QSY'ing to a clear frequency, just as phone operators also generally do. Even though horizontal polarization was emphasized, the fact is that hams with FM only rigs do not have horizontal antennas and vertical to vertical should work very well, even if there may be a slight edge to horizontal. Has anyone else been able to do any comparisons between H to H and V to V on FM? All the current SSB phone weak signal operators and VHF contesters use horizontal polarization. If those operators simply download fldigi and get an interface (the SignaLink USB works really well, even on FM-only transceivers with no VOX), they will have an incentive to work more grids and states during contests. For long distance FM DX, these operators, already equipped with high gain antennas (horizontally polarized) and amplifiers, looking for more grid multipliers and Q's during the VHF contests, probably represent the largest potential intererst group for working FM DX other than those with FM-only transceivers looking for new ways to enjoy the hobby. So, those who want to work them will need to get a horizontally polarized, fairly high gain antenna, and a small rotator. The gain of most current verticals that are not on a rotator probably tops out at around 6.2 dBi, which is not enough gain to work very far, except during strong openings. To work any reasonable amount of FM DX, a rotator and an antenna with at least 10 dBi of gain will be needed, and the VHF contesters generally have 14 dBi of antenna gain or more. It is not anticipated that very many of those interested in working toward VUCC on 2 meters, or even doing fairly well in VHF contests, will be satisfied with the range of their current verticals (even to someone else's current vertical), so if a higher gain antenna is needed, they might as well go to a rotator and horizontal polarization and be able to work the existing weak signal operators that we think will only need to add an interface in order to improve their contest scores by working both FM DX and SSB DX. Those who already have vertically polarized yagi's and still want to work repeaters can just rotate the yagi 45 degrees in roll and cover both polarizations with 3 dB less gain on each polarization. However, 3 dB is very significant in terms of range on 2 meters, so the operator may later decide to rotate the additional 45 degrees and pick up the additional 3 dB in gain. We are using 145.000 MHz as a calling frequency in our area, which has seemed to work out quite well. It is still within the SWR bandwidth of the high gain 2 meter SSB weak signal antennas and far enough away from repeater frequencies so as not to experience any desensitization. 145.000 is also within the ARRL Bandplan for 2 meters in the Weak signal and FM simplex area. 73, Skip KH6TY
Re: [digitalradio] NBEMS QST article/digital weak signal FM
Skip, White noise tests show DominioEX-4 to be a bit more sensitive than MFSK16, but it doesn't seem to handle HF distortion nearly as well. I was surprised that it did better than MFSK16 with multipath and was wondering if you thought the better throughput was due to MFSK16 tuning issues rather than actual robustness? Tony - KHMU

Re: [digitalradio] NBEMS experience today
Most of your questions are answered here: http://pskmail.wikispaces.com/PSK_arq 73, Rein PA0R -Ursprüngliche Nachricht- Von: digitalradio@yahoogroups.com Gesendet: 07.01.08 02:37:18 An: [EMAIL PROTECTED] Betreff: [digitalradio] NBEMS experience today Several of us were around the 10137 frequency earlier today and tried various combinations of modes, including NBEMS. We had at least KH6TY, K3UK, VE5MU, KC7GNM, and WD4KPD. Some attempts at making transfers was done. I sent Skip one of my standard messages which is the Gettysburgh Address. It took about 6 minutes or so to send with its 1419 character length.using the PSK63 speed. I unfortunately did not record this exactly. Not really fast, but we had quite a few repeats due to conditions being marginal. Again, this mode is intended more for VHF, but it does work on HF, even with fairly modest signals. The main thing is that the message was completely accurate at the receiving station, something nearly impossible to do with most of the sound card modes. What we probably should have done is try the same message with FAE 400 mode and compare the throughput under similar conditions. Eventually it sounds like NBEMS may have a chat mode, which I think would be a good thing, but you can easily switch back and forth between the flarq ARQ add-on and the basic VBdigi program. I wonder if it might be possible to eventually add the FAE 400 mode? In fact, later on I was tuning around and VE5MU was down the band calling on FAE 400 and I just sort of set my cursor on the waterfall and I was connected. We had a lengthy chat and if you have used this mode, you know that it is hard to keep up with the throughput with less than 40 wpm keyboard speed:) And that is when conditions are not the best. I am wondering if it might be possible to have this mode eventually available on VBdigi as it clearly is the superior ARQ HF sound card mode at this time. You can use wide FAE for more speed, but it is no where near as sensitive as the 400 Hz narrower mode. And for those of us who really do not want to operate with moderate width modes (under 500 Hz), the 400 Hz wide mode is ideal. The 10130 to 10140 sub bands under the new Region 2 Band Plan recommends no more than 500 Hz bandwidth. Questions about NBEMS: 1. I think I asked something like this before, but bear with me. It seems to be sending several blocks of data because you see the inserted characters that must be a checksum and if the receiving station decodes all correctly it knows that. Is this a CRC kind of check or something similar? 2. Am I correct that it only requests the parts that it can not decode properly? And it does this even though in between blocks are OK and so don't need ARQ? So you can send maybe three or more blocks with the check and if only one is bad it only resends that one? 3. If it needs to repeat one or more blocks, the transmitting station does the repeat, but then continues to send new data as well? Probably to fill a maximum number of bytes per transmission? 4. If you see someone sending the flarq beacon in VBdigit, and their callsign, is that just a general call to anyone? Or is there some way to differentiate who is to get the message? 5. And then when their callsign appears automatically in the flarq program, does that mean they are trying to connect specifically to your callsign, or is your flarq program just responding to any flarq beacon? 6.

[digitalradio] NBEMS experience today
Several of us were around the 10137 frequency earlier today and tried various combinations of modes, including NBEMS. We had at least KH6TY, K3UK, VE5MU, KC7GNM, and WD4KPD. Some attempts at making transfers was done. I sent Skip one of my standard messages which is the Gettysburgh Address. It took about 6 minutes or so to send with its 1419 character length.using the PSK63 speed. I unfortunately did not record this exactly. Not really fast, but we had quite a few repeats due to conditions being marginal. Again, this mode is intended more for VHF, but it does work on HF, even with fairly modest signals. The main thing is that the message was completely accurate at the receiving station, something nearly impossible to do with most of the sound card modes. What we probably should have done is try the same message with FAE 400 mode and compare the throughput under similar conditions. Eventually it sounds like NBEMS may have a chat mode, which I think would be a good thing, but you can easily switch back and forth between the flarq ARQ add-on and the basic VBdigi program.

Re: [digitalradio] NBEMS/Flarq Frequencies
Being so close to another net frequency is not going to work unless you provide a proper filter. Using flarq efficiently you need to * use a 500 Hz filter or better * use a distance of 500 Hz. We have tried to put 2 pskmail servers on a 250 Hz distance but they qrm'ed each other in such a way that is was not feasible. We had to increase the distance to 500 Hz. To use a broad filter and let the DSP do the filtering is basically wrong. The AGC will wipe out the flarq signal to the effect that all packets are damaged and no transfer is possible. To take advantage of the small bandwidth of PSK63 you need to have a matched (100 Hz) filter. If you don't have that it makes more sense to increase the speed to PSK250. That has the added advantage of being less frequency-critical. Just some of the experience we gathered with pskmail... 73, Rein PA0R Pronet came on and I was unable to print anything for it, my beacon will be 10.137/1500hz, I have one single short file in the folder for tranfer.

Re: [digitalradio] NBEMS/Flarq Frequencies
This rather surprises me as I can normally decode PSK31 stations right next to each other with no problems at all. Even if they are almost touching each other on the waterfall. And that is using a very wide filter, typically voice bandwidth, unless I have some very strong signals that is desensing the rig too much. Did you mean that the center frequencies of the PSK250 mode were separated by 500 Hz? If so, that would be as close as you could possibly get at that baud rate and bandwidth since each modulation would be out about 250 Hz from the center frequency. Anything closer than 500 Hz from the center frequencies would overlap with a 250 baud rate. 73, Rick, KV9U Rein Couperus wrote: Being so close to another net frequency is not going to work unless you provide a proper filter.

[digitalradio] NBEMS Frequencies.
I have VBDIGI/FLARQ up and running,and there has been a lot of posts about 30m frequencies. I do not have a 10Mh antenna so would like to know of frequencies for 14 and 7Mh, so that I can monitor/beacon in the right spots. Kevin VK5OA
Re: [digitalradio] NBEMS Frequencies.
Kevin, Do you realize that 3 x 3.5 = 10.5, which is close to 10.137. An 80m antenna will operate on the third harmonic for 30m operation! I have never seen this published as far as I can remember. Lots of references to using a 40m antenna on 15 m, but not to using an 80m antenna on 30m. This is what I am doing and it seems to be working, but I don't know what takeoff angle I have. Have to model it to find out. So, if you have an 80m dipole (my 80m antenna is a base-load, tophat vertical in the attic), try it on 30m. Just might work...

I definitely kept the newer file, of course. My question was asking the reverse, as maybe in some cases, the ones not having problems were the ones who did not have the newer file on their computer. The newer directX support apparently takes care of the older OCX OLE structure.

Re: [digitalradio] NBEMS/Flarq Frequencies
Propnet on 30m was very strong here. Around 1100 Hz when my transceiver was set to 10.137, I think. Correct me if I am wrong, but nothing wrong with working along side Propnet, just not on top of it. No problem - just wait for a few minutes and if and when Propnet comes on, move over a few hundred Hz. LIke Flip Wilson's Geraldine used to say, What you see is what you get, Honey (on the waterfall).

Re: [digitalradio] NBEMS/Flarq Frequencies
Aren't the PropNet operators monitoring their transmissions? Here in the U.S. beacons are not permitted below the 10 meter band except for the special international beacons. I realize that there are scofflaws (or worse) operating outside the rules, but it does not seem wise to promote this unless it is determined legal by the FCC ( I have not heard back yet from the FCC for help in understanding numerous issues and operations that are going on our bands). If anyone transmits a test signal (which PropNet is likely considered), and then someone else comes along and uses that frequency, such as a digital mode Q, then that frequency is busy and it is illegal for anyone to intentionally transmit on that frequency if they can hear either of the stations. Today I was able to correctly configure my emachines computer to run the vbdigi software using the suggested frequency of 10137 +1000 Hz. I happened to be on the same time as Skip, KH6TY, and so we were able to work each other although signals were fairly weak with his 3 watts to an inside antenna. (Hey, not bad, right?) The solution for the computer problem, was to insure that both the input and outputs in the Windows Control Panel Sound applet were going to the same sound card. But in order to use my Sound Blaster Live! card, I was forced to make it the default card under Windows. This created some other problems with not being able to use the front earphone jack that connects to the Realtek built-in card, for listening to MP3's, etc., but it seemed the only practical solution for now. At least I can key up the old rig with VOX, via rear panel connectors, which is something I can not do with my ICOM 756 Pro 2. 73, Rick, KV9U Andrew O'Brien wrote: I think it might make sense to use the SAME frequencies as Propnet.

Re: [digitalradio] NBEMS
Dave, Do not try to type at the same time you are linked with another station, because flarq is going to be sending keystrokes to VBdigi, often at the same time as you try to type. As you point out, NBEMS is a messaging system, not a chat system. It is also primarily for 2m emergency messaging, or NVIS on HF, where there is little QSB to contend with. The best way to play with it is to first establish contact without using Flarq. Then one of you presses the beacon button and takes it from there, only sending a stored email, stored text message, or picture and don't type until the progress bar on Flarq has progressed from white to green to full green and then white again. 73, Skip KH6TY Oh dear, fist trial with NBEMS was not a happy one, for me, I'm afraid... Appart from not knowing my way round the program, which is not the fault of the program of course, I also had terrible trouble with it missing keystrokes. Either it gave lowercase where I wanted uppercase, or it missed space bar keystrokes and it even missed several letters if I did not slowly and deliberately hit the keys as I transmitted. Appologies to the LY2 station who tried to work me on 20M today, if he's logged onto this reflector, I accidentally clicked on the Beacon and he responded and it went downhill from there. I guess it's not meant to be a chat mode system, but I'll be warry of how I play with it from now on! I'm using Windows 2000 pro on a 1.9GHZ AMD Sempron with a fair amount of RAM, if that helps debugging what was going wrong. Dave (G0DJA)

QSB is a major problem, of course, with the bands the way they are. And I'm guessing that the fading you get on bands like 23cm are going to make it difficult to use those bands as well? I guess there might be some interest for JOTA. Other than the age old 'Radio verses non-Radio' communications I'm thinking this may not get a great following in the UK/Europe. But, I could be wrong.

Re: [digitalradio] NBEMS problem
Rick, do you receive PSK31 signals on the waterfall, and do they decode properly into text? Does the 756 Pro 2 do the same with VBdigi? Do you have more than one soundcard/sound system in the computer? First we must establish that receive works and then address the transmit problem. You can always use VOX for PTT if you use the mic input of the transceiver.

Re: [digitalradio] NBEMS problem
Hi Skip, I have not been able to display anything on the waterfall for receive and no random printing to the screen from noise either. Same thing with both rigs on receive (I can't TX with the Pro 2 since no rig control to CI-V). Both sound cards were tried for both programs, switching back and forth and trying all sound card positions including Windows default. I have the built in Realtek Sound Card in this emachines computer, and an add on Creative Soundblaster Live! which is more accurate and I usually use that card. The receive and transmit work fine with Multipsk (no rig control, just keying the VOX) on either card for TX and RX decoding, but with the vbdigi there is TX via toggling the Tune button or the T/R button and the rig seems to transmit quite well and I think with a clean signal when monitoring on the other rig. Having done this kind of set up for many years and knowing of the pitfalls, I have not had a case where you could transmit OK but could not display anything on the waterfall unless there was a broken connection someplace. That does not seem possible since it works fine with Multipsk for both RX and TX. Just to clarify, I am using VOX to key the Kenwood TS-440 via the AFSK RCA jacks after I re-discovered (have not used this for digital for many, many years) that it can not be driven adequately via the Line out from the sound card when using the 13 pin DIN plug. 73, Rick, KV9U kh6ty wrote: Rick, do you receive PSK31 signals on the waterfall, and do they decode properly into text?

Re: [digitalradio] NBEMS problem
Hi Andy, We have been trying to isolate the problem, but no luck as yet. I do of course use SC #2 since my SB Live! card is the secondary card. (Naturally, I tried all kinds of other combinations too just in case, but no luck there). Other programs, including Digipan, and even programs I have not been able to transmit in the past, work quite nicely with VOX keying of the TS-440, including Chip64. When you loaded your software, did you get a warning that a file was newer on your computer and that it recommended you keep the file? In my case it was one of the system32 files: MSCOMCTL.OCX. 73, Rick, KV9U Andrew O'Brien wrote: It makes sense to me.

Re: [digitalradio] NBEMS available for beta testing
Kevin, I think you can trust this setup.exe. It is a Microsoft-generated installation program that only adds a few Microsoft DLL's to your system and installs the program files we have created. I'd go ahead and make an exception for this particular setup.exe. Skip KH6TY ZoneAlarm Security Suite has blocked setup.exe from creating a new process. If you trust setup.exe and believe it requires a process to be created, then you may want to change the Trust Level of this program. It is also possible that the attempt to create a process was malicious in nature. In that case, you should not change the Trust Level so that your system will continue to be protected. This is the first time that this has occurred on a great number of Setup exe's Consequently I am reluctant to proceed further. Any help appreciated Kevin VK5OA

The NarrowBand Emergency Messaging System (NBEMS) for Windows is a suite of software programs designed for point-to-point, fast, error-free, emergency messaging up to or over 100 miles distant, and takes up a very minimum of space on the ham bands, leaving more space for all other ham activites. The system is designed primarily for use on the two-meter band, or on HF with NVIS antennas, where there is a minimum of fading (QSB) to slow down message transfers. Two meters has the advantage that distances long enough to span disaster areas of up to 100 miles can be dependably covered with small, portable antennas. In hilly regions, if two meters is not workable over the distances required, NVIS antennas on HF can be employed instead, but are not nearly as portable. The system uses the computer soundcard as the modem and, other than a simple interface connection between the computer and transceiver, no additional hardware is needed.

This point-to-point system does not utilize repeaters, or email robots, for message forwarding.

ZoneAlarm Security Suite has blocked setup.exe from creating a new process. If you trust setup.exe and believe it requires a process to be created, then you may want to change the Trust Level of this program. It is also possible that the attempt to create a process was malicious in nature. In that case, you should not change the Trust Level so that your system will continue to be protected. This is the first time that this has occurred on a great number of Setup exe's Consequently I am reluctant to proceed further. Any help appreciated Kevin VK5OA

Re: [digitalradio] NBEMS HF testing frequency suggestion
Omar, good evening. It is a program that uses PSK (31, 63, 125, 250) . It can use regular PSK for keyboard chats but you can also decide to use PSK with ARQ if you want to send a text file or email where accuracy is important. The software works only under Linux, so the authors have developed a boot disc that one uses in a Windows PC. You burn the ISO file to a CD and insert it in a CD ROM drive, the Linux operating system boots up. You select a keyboard setting for you country and a video monitor setting. When the software boots up, you need to select FL-digi and go to the CONFIG area, insert your callsign. In the config area you can also choose your soudncard settings and PTT/rig control settings. If you want to use the ARQ side of things, you click on FLARQ, when it boots up you must also insert your callsign in it's config area.

Andy, where can I get NBEMS. Is it free to use ? On David's web side http://www.w1hkj.com , I only see something called flarq (fast light automatic repeat request) And what about making a windows version of this PSK (31, 63, 125, 250) ARQ mode?

[digitalradio] NBEMS boot problem
Just tried for a second time, and get the same results when trying to boot from the CD. It loads to a point, then stops, with an error message that says: Error, cannot find Puppy on 'cd' boot media. PUPMODE=1 PDEV1= Exited to initial-ramdisk(initramfs)commandline... (the Linux-guru can now debug. 'e3' editor is available) /bin/sh: can't access tty; job control turned off #_ And there it lays. Unsure if it requires input at this point or earlier in the boot process. First CD had the identical error. Thanks in advance Dave KB3MOW
