    Ref: https://projectavalon.net/forum4/show...=1#post1318752

    It is important to test radio, feedline (coax) and antenna before it is needed.
    Studying for an amateur radio license will help very much.
    Having a local friend who is an Ham will also be of much help.

    It is no longer necessary to learn Morse code (in the US).

    To avoid damaging the transmitter the system needs to be checked for reflected power (power not radiated by the antenna and reflected back to the transmitter) to avoid damage. This requires an SWR bridge to measure reflected power. Tests are conducted at very low power settings.

    Separate SWR checks are required for each antenna system.

    I am not encouraging anyone to transmit without a license but in a life threatening emergency it would be the right thing to do.

    Where did you get this information? What band repeaters - 2m, 70cm...?

    The ARRL has nothing about it on the website that I can find. It also sounds most unlikely and would kick up quite a stink in the ham radio community, along with the retailers of ham radio equipment designed to use repeaters.

    Wow, that's so hard to believe. Or to rationalize (without going into Orwellian scenarios, which seem the only explanation).

    Why force them to be shut down? Who benefits? That's all a bit like trying to make Morse Code illegal.

    Prepper News: Threat Reports and Preparedness News 341



    The People’s Republic of California is at it again; through unelected state officials, California is severing ties to ham radio repeater owners throughout the state, jeopardizing the lives of millions of Californians who depend on these repeaters to operate during emergencies.

    Last month, repeater operators were sent emails telling them the State would no longer allow them to operate repeaters on public land without paying substantial rental fees. In the letter sent by CAL FIRE, the state claims Ham operators no longer provide a benefit to the state or public safety. They claimed that “constantly changing technological advances” has made Ham radio obsolete during an emergency.

    Keep in mind; this is a state that is currently shutting power down in 34 of its counties because its infrastructure cannot handle 20-30 mph winds without risking wildfire breakouts throughout the state.

    What is a Ham Radio Repeater
    An amateur radio repeater system is a two-way radio system that takes weaker or low-level amateur radio signals and retransmits them at a higher level or higher power so that the radio signal can cover longer distances without degradation. It is a vital part of the local emergency communications system, and Ham Radio operators have been using them for decades to provide support during disasters that take out local communication infrastructure.
    Why would they remove something that is the last line of defense during a disaster?
    What is infuriating here is people are going to die because of this decision. It costs the State of California nothing to allow these repeaters on public land; in fact, Ham Radio Operators pay for the equipment and maintain the equipment at their own cost. Ham Radio operators also make nothing from running these radio repeaters; they do so as a service to the public to help ensure the public’s safety during natural disasters and emergencies.

    Here is a good explanation of what’s going on from a Ham Radio operator in CaliforniaWhile paying billions of dollars a year to cater to illegal immigrants and welfare bums, California is now targeting hard-working Ham operators who provide critical and vital Disaster Emergency Communications. These people have absolutely lost their minds!

    There is a nationwide effort to Kill Ham Radio



    Even most Hams haven’t taken notice, but in 2012 the federal government launched FirstNet, a public safety nationwide broadband network that many in the government think will make Ham radio operators obsolete. In reality, its nothing more than a $47 Billion Federal Cell Phone Network that itself is already obsolete. In fact, it needs LOTS of infrastructure to function, and it creates multiple, single points of failure.

    The real story here is Ham Radio is a threat to the government. We make them look stupid! They spend billions on infrastructure that breaks down, while we can literally take a hundred bucks in equipment, some random wires, and in minutes set up a radio system that can communicate with anyone in the world. Hell, I’ve used my kid’s slinky, some Television Coax Cable, and a solar battery system to build a mobile rig that I’ve used to talk to people around the world — You can check out the Radio Rig Here.

    They don’t want the public to realize that we can take care of ourselves, and do a much better and cheaper job doing so!

    Makes interesting reading. I can only surmise two reasons, 1 it's a free service and cannot have pecuniary gain, by Worldwide agreement. 2, if you want to blind your enemy shut down their comms. That is purely my assumption of course, if anyone can better my assumption, be my guest.

    From what information I've gathered, what California has done was ban amateur radio antennas from public property. Antennas on private property are not effected. Amateur radio antennas are often found on water towers and towers where other radio service antennas (commercial and public communications) are located. A high antenna is very helpful to extend the range of very high frequencies (VHF) and ultra high frequencies (UHF) which are popular frequency bands for amateur radio repeaters.


    Some California bureaucrats incorrectly think that amateur radio is useless in an emergency. The truth is that amateur radio will be the last man standing when things start to collapse.

    Those who are looking for the real reason might consider this:

    Amateur radio repeaters are widespread over the planet and their locations can be easily found. For example, I searched for repeaters in Ecuador using this link.

    There are two repeaters on the 2 meter band.
    146.7900 -0.6 MHz Cuenca
    146.9400 -0.6 MHz Cuenca, Santa Ana

    Some repeaters (not these two) have internet access which dramatically increases the number of people you can talk with, radio->internet->radio (or computer). But this feature goes away when the internet goes down.

    The most useful amateur radio band for long distance communication is 20 meters. Depending on time of day and atmospheric conditions the 20 meter band can be used to talk around the world. In this frequency band the signal can be bounced off the upper atmosphere then back to earth's surface. Multiple hops (skip) is possible (sometimes).

    I would not encourage anyone to transmit without a license. It takes a little education and training to set up a radio, feed line and antenna to operate effectively. Learning Morse code is no longer a requirement to get a license in the US.

    If the equipment is to be used in an emergency, it needs to be set up before it is needed. If set up incorrectly the transmitter can be damaged.

    I encourage all who are interested in fun with radios, or in emergency communications to find a local ham and ask for some help/advice, and please get a license.

    Oh dear. What a lot of muddled scary stuff in those links from mostly non-technical sources.

    Just in case anyone thinks ham radio is going to be closed down in California, no it's not. The fuss seems to be about the fact that if the repeater antennas are mounted on any structure that is not privately owned (like a well sited house) the local repeater group will have to pay the site owners considerably more for use of the site. Seems a bit petty as it doesn't actually cost anything (maybe a few dollars a month for the electricity to power the repeater equipment) to host a repeater. I know because I am familiar with such a set up. So rather than get a few hundred dollars rent a year, now the site owners will get nothing as the equipment will be relocated.

    Anyone can look into all the conspiracy, closing down free communication clap-trap if they like, but it's just that - clap trap. Unless that is someone can present accurate data from an ARRL press release to suggest otherwise.

    It's well recognised that ham radio is still very important in national emergencies. However in such cases the repeater network is of limited use since once the back-up batteries have expired (if there were any in the first place) the repeater is useless and ham communication will just have to fall back on local HF bands like 160 and 80m.

    No one is suggesting ham radio will be closed down. These people, LAW OFFICE OF A. NATHAN ZELIFF, seem to think it's a tad more serious than clap trap. Sending a fourteen-page email to the relevant departments.

    This is just the second page,
    Page 2 of 14Dear Ms. Pisi: I am writing you concerning your e-mail to Ham Radio Repeater owners advising them that they must remove all repeater equipment from various mountain locations unless they pay huge fees. (See Exhibit A – which is a copy of your e-mail). I am advised that this action is being done for the entire State of California. Many of these repeaters have been in public safety use for decades. They have saved lives. They have in fact been used for public safety and to protect life and property when the public communication systems have completely collapsed and failed during disasters. The cost to the State of California is nothing for these repeaters. Rather, Ham Radio Operators pay for the equipment and maintain the equipment at their own cost. The Ham Radio Operators do not make any money off of these repeaters. Your actions will destroy the existing Ham Radio Repeater System Infrastructure and Network that is a critical and vital asset for Disaster Emergency Communications. This Ham Radio Emergency Communications Infrastructure has existed for decades. Additionally, once removed, these Ham Radio assets will be cost prohibitive to rebuild. Moreover, your actions will serve to eviscerate the SHINGLETOWN EMERGENCY RADIO PLAN (SER PLAN), and directly expose residents of Shingletown (and other areas) to increased risk of being trapped by raging wildfires as well as subjecting residents to increased risk of loss of life from disasters. The result will be the same for all areas throughout the Entire State of California if this Cal Fire “DISASTER IN THE MAKING” is not IMMEDIATELY TERMINATED AND RENDERED PERMANENTLY - DEAD ON ARRIVAL! One of the foundational elements of the SER PLAN is: Early observation and reporting. This facilitates rapid response by Cal Fire and other emergency resources. In Shingletown, we have been warned that we could be the “next Paradise”. In order to try and avoid that prediction, Shingletown has continued implementing the SER PLAN. This PLAN has taken over 4 years to design, build, and refine. It is an operating emergency communications plan (combining HAM and NON Ham Neighborhood allocated frequencies). There are no fees, no dues and no one has to join any group. Hams and Neighborhoods just get on board, plug in and follow the plan. The SER PLAN has been described by a Shasta County Sheriff Lieutenant (Office of Emergency Services) as “robust”. The Lieutenant told me that he had reviewed the SER Plan and he was very impressed. Briefly, the SER PLAN involves coordination and communications within and between neighborhoods. We conduct weekly drills involving exactly the type of items recommended by the Sheriff and Cal Fire

    I have not seen anyone mention 2 extremely cheap "new" options.

    $20 RTL-SDR Transmit Only Huge Range
    $25 Baofeng UV-5R Allows you to transmit and Receive (Need License or Emergency to Transmit

    Software Defined Radio's start at $20 and allow you to listen only to Frequency Range: 500 kHz – 1766 MHz

    They come as a USB Dongle you plug into any computer.

    You can also go to websdr.orgto listen to dozens of SDR Radios stationed all over the world. Since one device can listen to multiple frequencies at once you actually get to choose nearly any frequency nearly anywhere on earth

    You got me excited for a minute there, but sadly:

    https://baofengtech.com/product/uv-5r/

    Discontinued product (Is that why it is so cheap maybe) and most certainly not a USB dongle

    I am a little confused by your post. Can you please elaborate is this two posts in one?

    The Beofang is currently available on Amazon $24.
    Battery Last a long time, a friend tested one at 10 miles and it worked great.
    https://www.amazon.com/BaoFeng-UV-5R...dp/B007H4VT7A/




    The SDR radios are a completely different device that needs to be plugged into a computer.

    Tradition analog radio receivers typically uses a variable capacitor to tune to specific frequencies. Software Defined Radios receive on all frequencies then use software filters to tune to specific frequencies. This allows 1 SDRadio to receive multiple frequencies.

    The cheap one's do not transmit

    $20
    RTL-SDR https://www.amazon.com/NooElec-NESDR...dp/B009U7WZCA/

    The more expensive ones transmit and receive in the range of 1MHz to 6GHz

    $324 HackRF-1 https://www.amazon.com/NooElec-Softw...dp/B01K1CCHR0/

    Anyone at all interested in HAM should definitely check out http://websdr.org

    It really highlights how powerful these SDR radios are and allows you to listen to nearly every frequency that exists. Special plugins can even be installed to listen to trunked radio and encrypted radio.

    Beofang products are cheap and popular transceivers. AFAIK they are only 2m and/or 70cm (VHF/UHF) and not HF, so only for local use, i.e. up to about 5 miles depending upon terrain, although repeater networks will extend this. Warning, they are not easy to use unless you are very familiar with small, multi-function key, menu-driven radio kit! They are not easy-to-use walkie-talkies!

    Cheap dongles can be quite fun, but their frequency coverage is usually pretty limited without modification, and are prone to overload problems (generate phantom signals that aren't there) and of course don't transmit. The antennas they usually come with are only suitable for receiving very strong local signals, and unless antennas are mounted some 10s of yards away will probably pick up loads of interference from the computer they are being used with! Antennas and dongles is a complex subject; too small and it won't pick up much, too big and the signals will swamp the device. And of course it also depends upon what frequencies you want to listen to as to what antenna you will need.

    I use the SDRPlay RSPdx. https://www.sdrplay.com/. Receive only, but covers 1 kHz to 2 GHz with appropriate antennas. I find it's a big improvement over their earlier SDRs, but it should be at about 200 UKP!

    Hi All,

    Just finished reading most of this thread. I have a few amateur radios here. If you're looking to become a ham operator your best bet is to get yourself the ARRL handbook and read it through, it should provide you with all the information to become a licensed ham operator. I also suggest joining your local amateur radio club every country will have one. Just get in contact with the president of the club and tell them that you want to become a ham operator and take it from there.

    The ARRL handbook covers everything.

    With regards to equipment, there is a lot of radios out there back in the day most of the were half solid-state and half tubes (final power output). Today they are entirely solid state, and now you get solid-state with SDR, the same goes with the price.

    If you looking for something go for a 2nd hand solid state like the Yeasu or Icom. I have both and they are brilliant radios. Make sure it has at least 100 watts. You don't want one that has a limit of 5 watts. In our field this is considered a QRP radio, meaning very low power and it provides another complexity where you might not be heard due to low power output. Some hams like this added complexity. It's a thrilling moment to make contact in a different country with 5 watts on the HF band.

    The antenna is another important part, It must be tuned or the reflected power from the antenna will damage your radio and then you will need to get that fixed. So hence why we use an Antenna Analyser and Tuner, to keep the SWR down.

    Coax is another factor to consider always make sure it's a good quality 50 ohm and has a minimum loss. Something like this

    Hope this helps.

    Cheers,

    Bill - did you ever get your ham setup? ( have you learned how to use it? ).
