The links to Christianity as far as I can tell (correct me if I'm wrong)
is directly linked to the Parable of the Wheat & Tares.
(found in Gospel of Matthew, which Jesus/Yeshua gave as a sermon on the mount of Olives).
The Parable of the Vinyard is more a warning to the Monarchy and government of the last day (reinforced by Psalm 94:20)
Also considering a day is 1000 years in terms of the creator (2Peter 3:8)
means that if Saul/Paul of Tarsus was the anti-christ/ teacher of anomia, that would make Harvest literally tomorrow (the next 1000 years since his arrival).
Paul is said to of died around between 64 and 67 AD
That would suggest his reign will not be defeated until 1064 to 1067 in todays terms the battle of Hastings.
2ESDRAS 6:9 gives the reference to the two warring factions on the earth at that time, the decendants of Esau (said to be contained in modern Jewry and the Roman Empire under the Herodian dynasty) and the decendants of Jacob (Esau's twin brother).
Links to Radio/Transmissions...
Considering the first 2 major world wars, the evolution of the worlds military, telecommunications and radio surveillance, RFID, Mobile civilian telecommunications (mobile phones are effectively 2way radios using fixed bandwith and giving location etc) plus the modern use of encryption for personnel in the field (so to speak), is the main technological means of identifying potential targets or tracking specific persons (think back to Jessica and Holly case) it is not hard to see why Radio plays a massive part in world affairs.
Another thing to consider is this:
If you DX you are making use of good conditions relating to microwaves from the sun and longwaves escaping the atmospheric layers to take advantage of optimal conditions for long distance transmissions.
Also since the one time pad still offers 100% encryption for longwave and shortwave is is still the preferred method of private communication anywhere in the world where radio can function, where man habits so will radio.
There are literally 100s of refferences to radio in popular culture, art and music.
From the NATLAB days at Phillips right through to specific references like "Radio gaga" (Queen) alluding to the very "infancy" of the use of radio (and the "someone" who still loves it).
Just my 2 cents
