[digitalradio] CQ RFSM-8000
Hi all, Is anyone in Europe interested in making tests with RFSM-8000? I am QRV some times on 14.109,5 calling CQ RFSM and in Server Mode. If anyone is interested please let know so that we can arrange a SKED. 73 de Demetre SV1UY
Re: [digitalradio] Re: Redefining SSTV operations
Patrick, Yes, but MultiPSK and DRM780 and fldigi and other programs already support MFSK and other modes. My point is that few know about MFSK picture mode, even though it is implemented in many programs, because it is accessible only when in MFSK mode and is hard to find. So, I propose simply making it more easily accessible, for example, by making it available on a main menu, or even as its own mode. In reality, it would simply be MFSK and would start with the Open File dialog box for image types, and in the case of MultiPSK and PocketDigi, it would send the RSID for MFSK.

It would be possible to put some RS prefix (with more bits available than for RS ID) to define the center frequency, format and color. But I'm not sure that the gain would be important as this type of SSTV is an old technology. Better would be a Digital SSTV within 500 Hz and as fast as standard SSTV. 73 Patrick

HI Leigh. That makes sense, but it would require Patrick to work with the GUI and he's not willing to do that, according to past comments.

Re: [digitalradio] Re: Redefining SSTV operations
In the US, we can send images in 500Hz bandwidth in the cw/data segments of the band, but if the bandwidth is higher than 500Hz, we must move to the phone bands. Andy is trying to foster a set of image operations down in what works out to be in the US data segment, so if we want to play, we have to do it in 500Hz. There was a discusion of OFDM recently here and I thought the upshot was that the throughput for 500Hz coding using multiple QAM carriers in 500 Hz would result in transfer times too long, so I suggested maybe we try making the MFSK analog mode more readily available. The DRM stuff is quite exciting and I hope to try it out sometime, but for now at least, it will have to be in the image/phone band, where we then can't do kbd-to-kbd data.

Re: [digitalradio] Re: Redefining SSTV operations
I don't have a problem with various kinds of UI, but I do know some people care intensely. One of the things I hope to accomplish with the znudigi experiment is a separation of modem from UI. I amworking with several different UI designs for znudigi clients, and hoping that others will too. Eventually, I hope the protocol is the outcome, and it gets incorporated into existing programs, such as fldigi, and perhaps even MultiPSK, so that alternate or special-purpose interfaces or applications can be built by those who consider themselves specialists in their areas, without having to delve too far afield. In other words, I am proposing modularity. 73 es GL, Leigh/WA5ZNU
Re: [digitalradio] Re: Redefining SSTV operations
Leigh, I have not been following this SSTV discussion very closely as I got the impression that it was analog SSTV when MMSSTV was mentioned as a program. Or is this actually digital SSTV? Can you give us a capsule account? Do you have any knowledge of any tests that have been done between RFSM2400 and the WinDRM/EasyPal type of OFDM? Even though this has to be done in the voice/image portions of the bands here in the U.S., it just does not add up that no one has done this kind of testing yet. And I have asked about this repeatedly. Are you or anyone else interested in doing these kinds of tests? I just recently got the capability to key up some of these modes (and most any sound card mode) from 160 to 6 meters, but on some bands with minimal antenna capability. Mostly ground mounted Butternut vertical. One of the very helpful things about the voice bands is that you can make contact on voice and then transmit the digital image on the same frequency. Very convenient if a problem comes up. The only down side is that you need reasonable good signals. But then again, I think we are going to find that for the most part, we will need fairly good signals for these fast modes. WinDRM and EasyPal require something around +8 dB S/N although the STANAG modems are supposed to be able to go much below that point. We may be able to partially simulate that by reducing power. Speaking of power, I can run well over 100 watts on most of the digital modes as I do have an Ameritron ALS-600 amplifier. For those who are thinking that this is an SSTV experiment, it really is more of a surrogate for the modem type. The only reason for using image data instead of text data is to meet the requirements here in the U.S. 73, Rick, KV9U Leigh L Klotz, Jr. wrote: In the US, we can send images in 500Hz bandwidth in the cw/data segments of the band, but if the bandwidth is higher than 500Hz, we must move to the phone bands. Andy is trying to foster a set of image operations down in what works out to be in the US data segment, so if we want to play, we have to do it in 500Hz. There was a discusion of OFDM recently here and I thought the upshot was that the throughput for 500Hz coding using multiple QAM carriers in 500 Hz would result in transfer times too long, so I suggested maybe we try making the MFSK analog mode more readily available. The DRM stuff is quite exciting and I hope to try it out sometime, but for now at least, it will have to be in the image/phone band, where we then can't do kbd-to-kbd data.

Harry Wiliford wrote: [edit] Etymology The word data is the plural of Latin datum, neuter past participle of dare, to give, hence something given. The past participle of to give has been used for millennia, in the sense of a statement accepted at face value; one of the works of Euclid, circa 300 BC, was the Dedomena (in Latin, Data). In discussions of problems in geometry, mathematics, engineering, and so on, the terms givens and data are used interchangeably. Such usage is the origin of data as a concept in computer science: data are numbers, words, images, etc., accepted as they stand. Pronounced dey-tuh, dat-uh, or dah-tuh.

Hey, John. Been on freq but not hearing PACTOR I. Called a few times. Did hear weak CW on occasion and one or two newer modes. I've heard you and I think I'm hearing you now at 0426Z but unable to print. Signals come and go momentarily on top of you (i.e. CW, Spanish sigs, a PSK31, but unable to print. Continuing to monitor.

Hi John At 0442Z the WD8DHF PMBO in Harker Hts, TX just started transmitting with an S9 signal. It is sending a Solar Flux Index accompanied by a cautionary request for users to LISTEN first before transmitting or losing privileges. I can hear a PACTOR signal underneath but obviously, cannot copy. I'm hearing now three total PACTOR signals.

[digitalradio] Introducing the K3UK Quick and Dirty Guide to Narrow-Band SSTV
I took the liberty of writing a quick and dirty guide to narrow band SSTV using MMSSTV. You can find the first draft at http://www.obriensweb.com/narrowsstv.htm . It is a little graphic rich, so it may take a little for the page to fully load. Hopefully the images display OK on the average PC monitor, I used a widescreen 22 inch monitor when composing the document. I will improve the document over time. The document describes the basics of setting up MMSSTV to do MP73-N and gives detail about how the templates and macros within MMSSTV can be used to achieve some aspect of keyboard QSOs with SSTV , rather than the traditional SSTV talk-and-then-send-a-picture method. Comments appreciated. -- Andy K3UK www.obriensweb.com (QSL via N2RJ)
