Range of radio stations

[kapuhy]

Seems like a fun project to start

As for directional antennas for specific areas - this can be somewhat solved by simply adding frequencies for propaganda in various languages, having like "BBC_Italy", "BBC_Germany" etc. and making sure target area is covered by station range. I'd be more worried about the disk space it would take to have enough multi-language news to make listening to the channel worth it.

That, and one would need people fluent in languages used, to search for and understand the content of broadcasts in order to put them in correct time.

yes, my point is that if you use real antenna coordinates, most shortwave (= long range) radio programs will be audible outside their historical reception ranges.

Well, the range "border" works really nice, just checked it by sailing out of station's range - radio gradually is replaced by white noise as you get close to the border, it feels very natural.

Bad news is we apparently can't have several transmitters sharing one audio folder - I made two "copies" of a radio station with the same folder but different names and antenna coords, and the game simply ignored the second one. So there goes my idea of having for example several time-limited transmitters for Grossdeustcher Rundfunk from occupied countries.

From your answer I understand that I didn't make myself clear enough. I will try with another example. During WWII, EIAR (the national radio broadcaster of the time) had in its schedule programs of Japanese music and news which were intended for the Far East. If I made those programs into a radio station with its antenna located in Rome and a range factor big enough to reach Japan, the same station would be audible not only in Japan but in the Western hemisphere as well, as far the East Coast of the States. This is obviously wrong: if I wanted the said programs to be only audible over Asia and maybe Eastern Europe, I should place its antenna in an arbitrary location somewhere between Italy and Japan, and reduce its range accordingly...

Good news for you: what you want to do has been achieved for SHIV, using a little trick:

So you end up with

[GENERAL]
RadioRealism=Yes
StartCh=1

[CHANNEL]
Name=Washington
Folder=Washington
Freq=22
Antenna=01.01.1930-01.01.2000:21.36,-157.96:6000

[CHANNEL]
Name=Washington-Midway
Folder=\Washington
Freq=42
Antenna=01.01.1930-01.01.2000:28.00,179.00:2800

[CHANNEL]
Name=Washington-Manila
Folder=\\Washington
Freq=52
Antenna=01.01.1930-02.01.1942:14.40,120.35:1600

My recommendation for you is to read carefully the following threads, as they contain information and ideas that you might find useful

No no, I got it This wasn't answer re directional transmitters, I was happy to see exiting radio range won't cause strange effects like audio suddenly popping in and out.

As for directional transmitters, if we can make several radio stations use the same folder and very close frequencies, theoretically you could make a directional transmitter by stacking "fake" transmitters along the common axis, like this (of course, since this is sea game we'd skip ones that only cover land):



Thanks for the links, reading these threads now!

Okay

That's a nice idea, but I am afraid it has some shortcomings. The programs of two or more radio stations broadcasting on very close frequencies are mixed together where their respective ranges overlap with each other. That wouldn't be a big problem if those stations broadcast the same programs at the same time, but I think that even if two stations shared the same music folder, they will never play the same music at the same time, due to that game shuffling the music for us

My pleasure kapuhy. Let us know if they help

Just tried this and you're right, I was hearing two different songs from the playlist at the same time. Perhaps if one could arrange the transmitters in such a way that their range circles overlap mostly over land...
