    A Fauci fan said he donates all that money to charity.
    Another poster said that means he keeps ever cent of his $450K retirement.
    The Fauci fan never responded.

    Our doctors who dared disagree were hounded by the media and medical licensing boards.

    What follow the science really meant is follow the money.

    indeed, now the facts are coming out, our crime minister's advisory board on the batstew flu didn't include 1 doctor. That's right zero doctors .....

    I can see that is entirely possible, as many of our colleges are accepting the unqualified over the qualified due to CRT. There is a rocky road ahead.

    They use a broadband spectrum analyzers.



    This is 15 meters, the one they are a lot fancier covering a huge area of frequencies. Adding superb RDF gear and they got whoever is transmitting.

    In Europe, there is a tax on tax on everything. I belong to a private forum; one of the members lived in Finland. When his kids were at the age they needed to use the internet; he left the group.

    Yea I've seen a antenna van cruising the area we were billeted in doing sweeps.

    Yup....that is how I am told it is done in Europe .....by a van with special equipment designed to find/isolate certain frequencies within one's receivers.

    The secret of NVIS antennas is they aren't as stealthy as many think.. Unless one believes an up to 80 air mile radius from their location is stealthy. ;)
    No, such NVIS antennas are not stealthy per se.....

    Once you key up ...anyone with the correct type of equipment....can find you. This type of equipment can be expensive and mostly owned by governments.

    Learning to operate split frequency helps but it is not that stealthy...,.also running a lot of power is not stealthy as well.

    Also, if one knows...changing polarization helps under some conditions...particularly with a directional antenna if one knows how to use it....but again not totally stealthy per se..

    Once you key the microphone ....you can be found with the correct equipment.


    Also many do not know that in Europe you have to pay a special tax on your radios and televisions.....and there is equipment which can detect if you are running an untaxed receiver. Be warned.

    My ICOM goes to 70 MHz from below AM radio, the Kenwood from below AM to 30 MHz; both are all mode. The ICOM can lower its power out; however, I haven't measured how low. The Kenwood 6 is a pure CW rig with Fox Tango 8 pole crystal filters at 250 and 400 Hz.

    Split frequency is easy both my ICOM and Kenwood are easily capable. Even my TS-530 SP (Ham bands + WARC) can with its external VFO. Rare DX always sends CQ DX CQ DX up so split frequency capability is an absolutely necessary to work rare DX.
    A waterfall display makes it a lot easier than it used to be.

    For security? One time pads are great. Even frequencies can be controlled.

    The FCC's regulations create all Hams equal or 1000 kW on CW and 1500 kW on SSB. There are two legal ways to break into a pileup. A low SWR or a gain antenna.


    Another thought is Software Defined Radio or SDR. Imagine a waterfall display showing every transmission.

    OH...yes...I've heard of NVIS antennas. My base station antenna..is a long wire loop antenna consisting of a 500 foot 12 gauge stranded roll of Lowes black insulated wire run through the tops of the trees on my property....and hooked up to a tuner. I've tuned this through the 50 MHZ band...from down to the AM broadcasting band.... ICOM 706 MK II and the G90 Xiegu Radios.

    I keep a G5RV antenna and coaxial cable rolled up in the back of my truck for when I am traveling and want to temporarily set something up more efficient than my truck mounted antennas. MY truck rig is a Yaesu FT 100 D....and I like it very much.

    Oh..and the Olde Elmers were correct and as time went on ..with experience...you learn that you don't always have to run gobs and gobs of power....and antenna efficiency is a big part of that. Antenna Efficiency./.System Efficiency is a huge part of radio operations.

    I've made the trip to my friend's home in Eastern Tennessee a distance of some 400 miles on 5 watts on LSB mode on 75 meters. Before any lower put me down in the weeds so to speak.

    A certain amount/kind of efficiency is always a good thing nor matter what kind of labors or tasks in which one is involved. One tries to be efficient without getting too complexity involved...which brings to mind another olde military saying....the KISS principle....Keep It Simple Stupid!!

    The two seem to run together...quite well if properly applied...

    And NVIS antennas fit the bill for me....Efficient and Simple...


    Oh...and you are correct Tugaloo..in that many preppers are not naturally inclined with radios or antennas.

    People like us are more naturally inclined and have certain curiosities...also we tend towards wanting to know if we can cut it...if we can do it ...make the grade...problem solve..have the right stuff so to speak.
    A kind of natural curiosity in this arena.


    Oh...this brings to mind something I told a prepper at work about security...
    He was asking about scramblers..on radios....
    There are some available, but most I've seen at any affordable cost are inverters..and invert the audio on the microphone...
    This meaning that all one has to do is select the correct sideband mode and unscramble...most do not know or are not aware of this about voice inverters/scramblers.

    A more simple and efficient manner of security in radio operations would be split frequency....but takes some skill and learning/experience to do this well. Transmit on one frequency and receive on another. The individual to whom you are speaking does this in reverse...receives on your transmit frequency and transmits on your receive frequency.
    I have used this method...on occasion and some newer radios can be set up to do this automatically with the key up of the microphone.

    This is also how one learns to operate one's radio when the channels/Frequencies are packed/crowded.

    I have a Nagoya NA-771 for my Baofeng 8 watt. The Nagoya works quite well; I use the Baofeng as a scanner to monitor police, fire etc.

    The NAGOYA NA-771 antenna is Tx optimized for 140-150 MHz and 420-450 MHz.
    The exact optimization is 144 MHz and 430 MHz, and has a gain of 2.5 dbi. It’s whip is nearly 16 inches long.
    Baofeng UV-5R antenna upgrades (verified SWR) for Ham bands, GMRS/FRS, MURS, Maritime, and Commercial business bands.


    I've noticed survivalists aren't the best with radios and antennas. Have you heard of NVIS antennas? I've read one can be used for short range securely without being detected by the boogey man.
    Just for the heck of it, I built one.

    I didn't make a contact as far as they said; however, anyone looking would have heard me.

    I believe the attempt to make Baofeng radios illegal is "supposedly" they are not FCC type accepted. IMO, it is more the Baofeng can RX/TX on frequencies where it is illegal or requires a license.

    GMRS/FRS and also MURS on the Baofeng Walkie Talkies

    FRS and or GMRS radios work in the 400 plus MHZ band..and are FM radios ...thus limiting their range and or usefullness. The power rating is some half a watt....which also severely limits the range.

    Also these radios do not have antennas which can be removed and or replaced with more efficient antennas including a base station antenna.
    I have couple of these radios...rechargeable..but seldom use them



    This is my reason for preferring the Baofeng UV 5 R series of radios....they will get the FRS and also the GMRS radiio frequencies at a higher power level..some one to two watts at the 400 plus MHZ Bands and higher power levels...lower on the frequency bands.


    But.......when operating these radios....you have to know the exact frequency to manually enter it into the radio...
    The FRS and or GMRS frequencies are available on line...the exact digital frequencies.


    When operating from home...on FRS and or GMRS frequencies....I am running my Baofeng walkie talkies on a base station antenna...a home made J pole antenna up about 60 feet and thus significantly extending my range.

    Something else no one usually tells you ....


    There is a list of frequencies...called MURS...Multi USe Radio Service..here on these frequencies available on the Baofeng UV 5 R series of walkie talkies...and no license needed..I also use these frequencies and a number of CB people are quietly discovering this as well. This is lower down on the frequency band and thus also extends range though still FM transmission mode.

    Here these MURS radio frequencies..



    151.820 MHz (11.25 kHz)
    151.880 MHz (11.25 kHz)
    151.940 MHz (11.25 kHz)
    154.570 MHz (20.00 kHz)
    154.600 MHz (20.00 kHz)

    I have both the FRS and GMRS frequencies programmed into my Baofeng Walkie Talkies as well as the MURS frequencies...and several more efficient antennas by which I can replace the factory antenna.
    Most walkie talkies..the factory antennas are marginal...at best..


    You decide for yourself, but you will have to do additional homework to become familiar with the numerical frequencies to put them into the Baofeng Radios....

    What you get with the Baofeng Walkie Talkies is more flexibility .... versatility than the FRS type radios...which is why I Like them. Oh...and on these walkie talkies...you can also cut the power up or down lower as needed...this may become important in security when needed that you not become too visible to other radio operators.

    You decide for yourself and your group....but information is knowledge..is power.

    I keep one of these Baofeng UV5 R Radios at work and thusly programmed with GMRS/FRS frequencies and also the MURS Frequencies. More efficient antennas as well as spare batteries and charger. I recharged this Walkie Talkie/Handi Talkie/HT the other day just to insure it is ready to go.

    If needed in ...addition to a more efficient antenna ..I know to take this rig/radio up to the roof of a certain building some 85 feet up for more range. There are things you can do to get more range.....keeping security in mind...OP SEC. For example...scouting your town or city for elevated buildings with roof access or elevated parking garages...again OP SEC in mind..Safety/Security.

    Oh...one more thing...I believe someone is trying to make these Baofeng walkie talkies illegal in America....too flexible and versatile for America and at a very good price...we cannot have that!!!!
    We have to be properly herded...!!! No independent thinking allowed...no thinking outside the box..

    Be Warned these Ishmaelites who would prevent you from thinking outside the box...much less..knowing and conducting yourself outside the box...and for your own interests.

    Kept a Baofeng 8 watt radio on line all night with the Tropical Storm Isaias bearing down on us and mostly monitored but occasionally checked into the local ham Emergency group to give my status report.
    Used the stock issue antenna as I was unable to find my more efficient one. Will have to remedy that situation soon.

    The Walkie Talkie is now back on the charger for the next time....I need it on the ready line..

    There is another suspected storm front working it's way out at sea....monitoring it on the National Hurricane link on the web.
