I have the Russian 5.45x39 cartridge listed as > 123 grain. Is this correct? Recoil is perceived but in the end it's the amount of double base powder packed into a cartridge case and weapon's weight and design that deals with the awful realities of muzzle climb and that shoulder hammering feeling all grunts get when they decide now is the time to bust off a few caps through a full cyclic burst. in any event the Sov 5.45mmx39mm round uses a 52-54 grain spitzer bullet that's extremely long for its class and comes out the muzzle just a hair under the 3000 feet per second mark. The AK74 has been noted for its nasty muzzle blast but light felt/perceived recoil due to the effectiveness of the muzzle compensator/brake. The M43 7.62mmx39mm round uses a bullet in the 120 grain range but of course because of a shorter cartridge case the powder load isn't anywhere near the levels of the amount packed in the 8mm Mauser or 7.62mmx54mm Russian semi-rimmed. > If it is, the AK74 has only slightly > less recoil than an FN-FAL, and more than a H&K G3. Is this data > correct? Can someone help me out on this? FALs and G3s belong more in the category of the Mauser 98 and SMLE due to the power of the .308 cartridge- assault rifle ammo comes in a class of its own...

This message goes out to Gamemasters. I am currently running a small twilight group. First, how do the rest of you handle radio traffic? Second, I have characters in my group that are interested in contacting other groups, and this would be a great cross gaming group conversation... not only that but detailing the exploits of the radio traffic would make for some great reading! (it also has great "motivational" factors for your plots lines!) Let me know what you think! P.S. My group is currently working on their character backgrounds and I will be publishing the exploits to those that will send me a direct email, so that there is no multi messges on the newsgroup, and we are currently setting up a web page specifically for this. Any other group that wishes to post exploits of their gaming group, please contact myself for more details. I will be sending the addresses out to the newsgroup, once everything is in place. Hope to hear for you, Cameron. *************************************************************************** To unsubscribe from this list send mail to majordomo@mpgn.com with the line 'unsubscribe twilight2000' as the body of the message. ------------------------------ Date: Sun, 15 Nov 1998 12:16:54 +0100 From: "Ronald A" Subject: sharing documents I have put up an ftp server here in europe which we can use to share large documents, adventures, and such. i'll put up an anonymous login just over the weekend for those of you interested in having a look.

UHF communications: are much more resistant to interference, cept that its line of sight.short range and susceptible to obstructions. The neat thing bout UHF though is that all mil-spec radios allow reception of freq.. 234.0 regardless of the dialed up freq.. VHF communications: is even more resistant to interference, but even shorter range and more susceptible to obstructions. The neat thing though is all mil-spec radios allow reception of 121.5 regardless of the freq. dialed up. The above calls are accomplished with the suffix "this rainbow six calling CALLING ON GUARD" so the person recieving knows your not on the dialed up freq but the emergency freq, to respond he'll have to dial up the emergency freq. Those 2 freq.'s are international and everyone knows them so user beware. All this is true and it helps game play.

On a side note, I remember talking to various amateur radio operators who remember when we had above ground tests, at the moment the atom bomb exploded, they heard a loud crack in their headphones as they tuned the HF (shortwave 3 - 30 Mc) bands that resembled a .22LR rifle going off. We tested in the Nevada desert and some hams even as far away as Alaska remember hearing this loud crack. One interesting phenomenon is when you detonate an H-Bomb in the ionosphere, you could also affect the opposite hemisphere's communications too at the same latitude. So if some "rocket scientist" would set off an H-Bomb at 40 degrees North latitude in the ionosphere, due to the Earth's magnetic field, it will effect communications at 40 degrees South latitude as well. I have a short article in a 1959 Life magazine where they actually did this as an experiment called "Project Argus." Back to the effects, most EMP falls in the frequency region under 100 Mc. Even at VHF freqs, you would get multi-path distortion where the signal will bounce off of the fireball and the reflections will arrive at the receiver's antenna at different times, much like how you see "ghosts" on the TV when an airplane passes nearby your antenna. As you said, UHF is the most resistant, but VHF would clear up in a matter of minutes to about a half an hour. Also on VHF and especially UHF, "line-of-sight" should still work. HF could take days. In some cases, HF signals could be improved in some areas while retarded in others. You have to take "pot-luck" there. Below HF, you have MF (medium frequencies, 300 - 3000 kc) which covers the AM band (520 - 1710 kc), LF (low frequencies - 30 - 300 kc) which mainly has navigation beacons and in Europe, longwave radio stations from 150 - 283 kc. At those frequencies and below, your skywave propagation will be affected such as long distance reception of AM stations at night but groundwave will still be OK. Groundwaves follow the curvature of the Earth from the point of origin to about 25 to 100 miles, depending on station power and frequency. When I DMed TW2K, my group was made up of survivalist/militia types so we relied on CB and Ham radios for two way communications. I just used my basic knowledge of radio to determine conditions and with an occasional random roll, determined HF and VHF-Lo (30 - 54 Mc, perhaps a little higher) for long distance communications. I just let most comms go through with no problem unless the characters are under fire, being chased in their cars by other "baddies" and such other dangerous situations where they had to roll occasionally to see if the message got through since they would have to mind other things like driving, not getting shot, and so on. One of my favorite things is when they twiddled the dial on their shortwave radios and scanners, making up what type of signals they would receive such as surviving shortwave/AM/FM/TV stations, other groups, and occasional military/shipping traffic.

The simplistic set up I described worked well. Like you I had them monitoring HF outa hope they could pick up some of the scraps I through them over it. But knowledge of the guard freq helps them against your civilian bad guys considerably, if the PC's are sharp enuff too utilize it. Now that you bring it up; does anyone have knowledge of West Europe, French and Warsaw Pact/Russian communication gear and freq useage?

Someone posted a question about radio's in europe, and I don't know much about it, but I do know that most civilian communication is VHF and UHF, while in thea rmy we used FM radios (no idea is that's any use) and had a backup link with single side band radio (our ones were ancient and were truck-mounted, I understand they've shrunk considerably in the meantime). While we're on the subject, I was wondering if someone could tell me a little more about what single sideband is and does exactly.

I have a November 1989 Popular Communications article on some of the radios that the French and British use along with their bands. In Europe, they considered VHF-Lo to be from 66 - 88 Mc for their public safety use although the militaries use anywhere from 30 - 88 Mc. I have a UK frequency chart and it seems the US Military is dominant in the 30 - 54 Mc range. The UK uses some of that range but can mainly be found in the 60 - 70 Mc area too. Most radios do operate in the 30 - 88 Mc range depending what frequencies the countries allocate and the common frequencies they have agreed upon. Some countries do have TV signals in that range too so that has to be taken into account. One interesting thing of note, until FM radio (88 - 108 Mc) was established in Europe, that part of the radio spectrum was used for public safety and things like taxi cabs and so on. Until a few years ago, the UK still used the 100 - 108 Mc portion for that purpose, maybe they still do, I don't know. The USSR/Russian situation is even a bit different. In the Eastern European countries and the USSR/Russia, their FM radio band was from 66 - 74 Mc although there could be a switch over to our FM band. TV over there rested in the 48 - 66 Mc area so I think they would use the 30 - 48 and 74 - - 108 Mc for public safety and military traffic. Most frequencies are agreed upon by international agreement such as the ham radio bands and AM radio but it's really up to the various nations to determine what goes where. Even over here in the US, the military does occasionally transmit in the 50 - 88 Mc range although it's rare because our TV channels from 2 to 6 (54 - 72 Mc and 76 - 88 Mc, each channel is 6 Mc wide) fall into that band with other things like the 6 meter ham band (50 - 54 Mc, which is gaining limited use in Europe and elsewhere), and the "VHF-Mid" band at 72 - 76 Mc where you find a lot of radio controlled devices, repeater stations, and aircraft ILS landing systems on 75 Mc. I'll have to read that article but that's pretty much it from memory for now. One could write a book about it.

A common error for the lesser trained (or tired or shot at)is to tune directly too the desired freq instead of too the middle of the 3000hz band, thus losing a portion of the signal. As opposed to a carrier only signal which is usually an on/off type signal (morse code is on/off). Later data transmitting systems included upper and lower side bands. Most radio entertainment fall into AM(HF) and FM(UHF) TV two signals one audio, one video both FM either UHF or VHF Marine band and Citizens bands are FM (VHF) So for twilight/merc purposes: operating a HF radio is DIF electronics skill. VHF/UHF are AVG electronic skills (because radios using FM dont have side bands). All this is over simplified, yet semi accurate. cheers Loonz - -----Original Message----- From: dragon@euronet.nl To: twilight2000@MPGN.COM Date: Wednesday, November 18, 1998 11:47 AM Subject: Radio Comms Hello everyone, I'm no radio buff, but if someone could post a slightly more expansive list of radio equipment (with an explanation of what everyone is and does) and a system for their usage I would be quite grateful. Someone posted a question about radio's in europe, and I don't know much about it, but I do know that most civilian communication is VHF and UHF, while in thea rmy we used FM radios (no idea is that's any use) and had a backup link with single side band radio (our ones were ancient and were truck-mounted, I understand they've shrunk considerably in the meantime). While we're on the subject, I was wondering if someone could tell me a little more about what single sideband is and does exactly.

Then too make use of the VHF as un reliable as I can (Murphy factor). Then encourage use of UHF for battle coordination, depleting of starting funds, and target practise when they blow thier AVG skill rolls. :-) Now include Nationality of brand +1 difficulty level unless language skill is present, and increase the difficulty if using enemy radios +1 level, and if thier mismatched +1 level. Makes bringing Sparks all the more important. cheers Loonz - -----Original Message----- From: Chuck Mandus To: twilight2000@MPGN.COM Date: Wednesday, November 18, 1998 1:06 PM Subject: Re: Radio Traffic >It seems like a lot of us put knowledge that we have and gained throughout >life and apply that to our games. > >I have a November 1989 Popular Communications article on some of the radios >that the French and British use along with their bands.
