    Is your region under constant bombings, arbitrary shootings, and a disintegrating political structure? Are you a journalist living in one of these regions? How to get your story out? Amateur Radio Packet Radio would fit the bill. As long as all you have to report is in text, this would be a most excellent way to get to your news agency in a method that isn't easily stopped. There are many HAMs out there, but most do not have triangulation capacity or if they did it would be of a low-resolution. So keeping your transmissions short and sweet with a "fast" 28.8 K link is a great way to sign-in without having a gun to your head and you signing out permanently. This is a very viable method of covert communications. For the best of the best you could encrypt your pay-load and set it to send the file (with error correction) to your destination, keeping it sending until completion. It should be noted that in normal situations the use of crypto over amateur
    radio is frowned upon (potentially illegal) but in a war zone no one really cares in the slightest that they might be breaching standard protocol.

    Cheers!
    Best regards,

    When you say triangulation, are you referring to people using triangulation
    to locate and identify HAMS as the source of the transmission or HAMS using triangulation for some other purpose. If the later, what would be their purpose.

    My license expired a long time ago and have not kept up so I am curious about what this might be used for.

    Triangulation using directional antennas and attenuators can prove to be very effective. I did many experiment with that being younger...

    I was referring to Ham Radio operators efforts at DX'ing or Distance Foxhunting. Some Hams are really seriously skilled and they track down
    sources of odd signals in their free time, if the transmitter is attractive enough. They would take signal strength samples in different locations, find the signal with the highest strength then surround that point with three
    points and finally determine where that signal if originating from.

    Ah, I have heard and read about DX'ing but was not active in Ham Radio long enough to take part in any of those events. When I was active for a short while I used a Heathkit 5Watt CW transceiver on mostly 80 meters. Since that time I have been fascinated by QRP but have not studied to take the exam
    again.

    By "attractive" are you referring to the equipment (rig), Signal Strength, or the operator? LOL

    I'd like to chip in regarding DX. By nature, it involves long distances,
    mostly in mid-HF (Between 40m and 10m). This also involves bouncing the ionosphere to reach another point far away. This can be estimated roughly with propagation models, solar sun spots and many other factors but is highly speculative. Physically locating someone in a DX QSO on HF is almost
    impossible except maybe it's general direction with a directional beam and a rotor to turn the antenna. But in that case, the distance will be your major issue, 5000km away is hard to triangulate and the propagation window is
    usually short as it tends to follow the sun more or less.

    For example, if I make a contact on 40M (7Mhz roughly) or 20M (14Mhz roughly) someone from 5000km can hear me but someone located at 1000km won't since I skip over him (one of the reason some call this skip).

    Fox hunting is something we see more on higher frequencies like 10M, 6M or
    2M. Each bands have their properties and preferred uses. CB users often do
    this to play since their installation rarely transmit over 40km. It's then easier to locate. The transmission mode also makes it an added challenge. FM
    or AM transmissions are easier to track due to their carrier while SSB modes are more difficult as they don't have a carrier per say.

    Anyway, very interesting world!

    Cheers!

    Hi nristen,
    I was referring to how exotic the signal is in its modulation.
