Hi All,
It has been two years since I have uploaded the NBTV encoder and decoder to GitHub, as there has been no interest in this ATV mode to date. It seems we talk a lot about the need to do more with technologies in Ham radio, yet I provide a cutting edge technology in the way of a hybrid transmission system to send TV picture long distance. I would of expected five or six people would of contacted me by now to try it out, but has not happened. There is no outside factor controlling what we can and can not do in the way experimentation as long as we stays with the limits of the Ham band been used (except for the United States). So therefore I have stop development work on this project, as I can be doing other things outside of Ham radio, that are valued. It seems we only have our own culture within ham radio to blame for current state of the hobby, as there was a lot more get up and go back in the 1990's, to try new things.
Grant,

Živjo vsem,
Minili sta dve leti, odkar sem na GitHub naložil kodirnik in dekoder NBTV, saj do danes ni bilo zanimanja za ta način ATV. Zdi se, da veliko govorimo o potrebi po več storitvah s tehnologijami v radioamaterstvu, vendar jaz ponujam vrhunsko tehnologijo v obliki hibridnega prenosnega sistema za pošiljanje TV-slike na dolge razdalje. Pričakoval bi, da bi me do zdaj kontaktiralo pet ali šest ljudi, da bi jo preizkusili, vendar se to ni zgodilo. Ni zunanjega dejavnika, ki bi nadzoroval, kaj lahko in česa ne moremo početi pri eksperimentiranju, dokler ostajamo v okviru uporabljenega radioamaterskega pasu (razen v Združenih državah Amerike). Zato sem ustavil razvojno delo na tem projektu, saj lahko počnem druge stvari zunaj radioamaterstva, ki so cenjene. Zdi se, da lahko za trenutno stanje tega hobija krivimo le svojo lastno kulturo znotraj radioamaterstva, saj je bilo v devetdesetih letih veliko več ljudi, ki so se želeli vrniti in preizkusiti nove stvari.
Grant,

That's a pity that you have stopped your developments about NBTV Grant !
Our entire community is loosing something !
That's to say that I have translated your messages for the french
community on my web site during you were in development. Interest was great.
Personnaly j have made a lot of ATV since the beginning of this technic,
mainly on uhf-shf, from 430 MHz to 24 GHz. Also on 10 meters but only
locally (60 km).
Helas the main part of our ATV community is coming old now, me too hi,
and we are less quick to react to new technics. That's the case with
what you have developped.
For my part, i was waiting the results of you first QSO on short waves
to begin to build something in TX. I am already QRV in reception in
DVB-S and T in any frequency because I have built an universal DATV
recever covering any QRG between 50 kHz to 3.2 GHz, and up with
converters, 5.7, 10 and 24 GHz.
I have not implemented your solution because, as told, I was waiting
your first results. Actually, I have not enough power and antenna to be
able to reach you on 29 MHz. But I can buid something...
Is your decision definitive Grant ?
I hope not.

Škoda, da ste ustavili svoj razvoj o NBTV Grant!
Vsa naša skupnost nekaj izgublja!
To pomeni, da sem vaša sporočila prevajal za francosko
skupnost na svoji spletni strani med vašim razvojem. Zanimanje je bilo veliko.
Osebno sem od začetka te tehnike naredil veliko ATV,
predvsem na UHF-SHF, od 430 MHz do 24 GHz. Tudi na 10 metrih, vendar le
lokalno (60 km).
Hvala, večina naše ATV skupnosti se zdaj stara, tudi jaz,
in se manj hitro odzivamo na nove tehnike. Tako je tudi s tem,
kar ste razvili.
Kar se mene tiče, sem čakal na rezultate tvoje prve zveze na kratkih valovih,
da bi začel graditi nekaj v oddaji. Jaz že sprejemam v
DVB-S in T na kateri koli frekvenci, ker sem zgradil univerzalni DATV
sprejemnik, ki pokriva kateri koli QRG med 50 kHz in 3,2 GHz ter navzgor s
pretvorniki, 5,7, 10 in 24 GHz.
Nisem implementiral tvoje rešitve, ker sem, kot sem rekel, čakal
tvoje prve rezultate. Pravzaprav nimam dovolj moči in antene, da bi te dosegel
na 29 MHz. Lahko pa nekaj zgradim ...
Je tvoja odločitev dokončna, Grant?
Upam, da ne.

Hi Michel,
"Is your decision definitive Grant", No, it all based on the level of interest, I need to find the best use of my time. As I need to rework the NBTV software to work with the recovered sync, for both the video and the sound information. This is a major undertaking to do, it is going to be about six weeks of work, if at the end of this work for there is to be no interested in using this software. In that case how else could I make better use of that time, as I have a number of circuit boards I need to get done and I have some FPGA development work to do as well. So based on the last two years of next to no interest for an ATV DX mode for HF, I have just decided to work on other things.

Živjo Michel,
"Je tvoja odločitev dokončna, Grant?" Ne, vse temelji na stopnji zanimanja, zato moram najti najboljšo možno izrabo svojega časa. Ker moram predelati programsko opremo NBTV, da bo delovala z obnovljeno sinhronizacijo, tako za video kot za zvočne informacije. To je velik podvig, ki bo trajal približno šest tednov, če na koncu tega dela ne bo nobenega zanimanja za uporabo te programske opreme. V tem primeru, kako bi drugače lahko bolje izkoristil ta čas, saj moram dokončati več tiskanih vezij in opraviti tudi nekaj razvoja FPGA. Glede na to, da v zadnjih dveh letih skoraj ni bilo zanimanja za ATV DX način za HF, sem se odločil, da bom delal na drugih stvareh.

Don't worry Grant,
I thing that most of us were waiting on results of your first QSO on
short waves before taking the decision to implement your solution.
Because the main problem in S-W with DVB-S, is to recover the synch
after a QSB or a QRM.
DVB-S works, but only when it's no QSB nor QRM, instead, it takes a lot
of time to recover, especially with low SR, and finally, it's difficult
to see most of the sent images.
Did you compare DVB-S and your solution Grant ?
I have not done tests with DVB-T in short waves because the tX and RX
can't work with low bandpass, only 1 MHz minimum with my Hides
equipment. It's too much for short waves.
If you see that you can do better, i can load your softwares and try
with a local ham. The problem momentally is "who", because in my
region, practically all of my regular correspondents are off. But if i
had the hope to do a fruitful DATV S-W QSO, i can use the Al Capone
method to force some european DATV enthusiast to do tests with me... hi
You know Grant, in translating in french your messages relating your
developments, i have seen a lot of interest. But it' also to tell that
this technic is very complicated for most of standard hams. So they were
reading but unaware to do more. When positive results would be done, i
am sure that all DATV people will implement your solution on their
equipments and do tests with it.
73 michel hb9afo
Ne skrbi, Grant,
mislim, da je večina od nas čakala na rezultate tvoje prve zveze na
kratkih valovih, preden smo se odločili za uporabo tvoje rešitve.
Ker je glavni problem pri S-W z DVB-S obnovitev sinhronizacije
po QSB ali QRM.
DVB-S deluje, vendar le, če ni QSB ali QRM, namesto tega traja veliko
časa, da se obnovi, še posebej pri nizkem SR, in končno je težko
videti večino poslanih slik.
Si primerjal DVB-S in svojo rešitev, Grant?
Nisem delal testov z DVB-T na kratkih valovih, ker oddajnik in sprejemnik
ne moreta delovati z nizko pasovno širino, le minimalno 1 MHz z mojo Hides
opremo. To je preveč za kratke valove.
Če vidiš, da lahko narediš bolje, lahko naložim tvojo programsko opremo in poskusim
z lokalnim radioamaterjem. Trenutno je problem "kdo", ker v moji
regiji praktično vsi moji redni dopisniki ne delajo. Če pa bi upal, da bom opravil uspešno zvezo DATV S-W, bi lahko uporabil metodo Al Caponeja,
da bi prisilil kakšnega evropskega navdušenca nad DATV, da bi z mano opravil teste ... zdravo
Veš, Grant, pri prevajanju tvojih sporočil o tvojem
razvoju v francoščino sem opazil veliko zanimanja. Vendar je treba tudi povedati, da je
ta tehnika za večino standardnih radioamaterjev zelo zapletena. Zato so jo brali, vendar se niso zavedali, da bi lahko naredili več. Ko bodo znani pozitivni rezultati, sem prepričan, da bodo vsi ljudje, ki se ukvarjajo z DATV, vašo rešitev implementirali na svojo
opremo in z njo opravili teste.

Hello Grand,
Until a few days ago, I hadn't read or heard anything about your development.
I would love to read more about it—how it works, what hardware is required, etc.
I have been participating in the Veron ATV contests for months; in the last contest, I managed to cover a distance of over 500 km on the 70 cm band.
I would like to achieve the same thing on HF.
Please keep sharing information with the OMs and YLs; there are surely quite a few people interested.
73, Thomas DL5BCA
Živjo Grand,
Do pred nekaj dnevi nisem bral ali slišal ničesar o tvojem razvoju.
Rad bi prebral več o tem – kako deluje, kakšna strojna oprema je potrebna itd.
Že mesece sodelujem na tekmovanjih Veron ATV; na zadnjem tekmovanju mi je uspelo prevoziti razdaljo več kot 500 km na 70 cm pasu.
Enako bi rad dosegel tudi na HF.
Prosim, delite informacije z OM-ji in YL-ji; zagotovo je kar nekaj zainteresiranih.

Grant,
What hardware is needed?
I know you have been talking about this for a while.
Could you stop by Wednesday night on zoom or maybe a step by step guide
as to how to make this work?
I have little experience with linux outside of ubuntu that was used for
Art's DATV Express board.
Dave KC3AM
Grant,
Katera strojna oprema je potrebna?
Vem, da o tem govoriš že nekaj časa.
Ali se lahko v sredo zvečer oglasiš na Zoomu ali morda s postopnim vodnikom,
kako to narediti?
Z Linuxom imam malo izkušenj, razen Ubuntuja, ki je bil uporabljen za
Artovo ploščo DATV Express.
