10/11 meters / Re: 11 meter private comms?
« on: February 11, 2020, 1320 UTC »
PRIVATE & 11m don't quite go together....

Not does any standard frequency, particularly if analogue.

So any Digi mode, the more unpopular the better and a wierd non standard frequency.

I'd have a look for some basic encryption handsets but I've no idea what's available in the US but due to the somewhat paranoid nature of your government I guess not much?

Sorry I can't really recommend something decent but best avoid 11m, obviously...

Str.

There are actually quite a lot of encrypted radios available on the market in the US.  You can even find old Motorola SECURENET handhelds (of course, finding a KVL or keyloader is a little harder, but it is possible...).  Encrypted Project 25 / P25/P-25/APCO-25 digital voice radios and encrypted DMR digital voice radios are widely available.  Encrypted DMR is easier to use and has a lower price point.  The secondhand market is quite large in the USA.  There is a wide variation in the type of gear, bands available, etc.  VHF low 25-50 MHz (and various "splits" within the VHF low band - for example, 29-37 MHz, 36-42 MHz, 42-50 MHz, 37-50 MHz, etc.), VHF high band (136-174 MHz or 144-174 MHz), UHF band (generally 400-450 MHz, 403-450 MHz, 380-430 MHz, 380-450 MHz or 450-512 MHz) and the 700/800 band (700 - 870 MHz) are easily found.  900 MHz equipment is also out there (generally the 896-901 MHz / 935-940 MHz land mobile radio band, but this gear will usually cover the 902-928 MHz ISM/33cm ham band easily).

DMR radios with encryption capability are generally going to cover the VHF high band and/or the UHF band.  Project 25 radios with encryption capability are available for the VHF/UHF bands and 700/800 band.  VHF low band gear is available with voice inversion at the very least.  Digital voice on low band is certainly possible

No frequency is completely private.  If the OP lives in a rural area and is smart about how he uses his radios, the likelihood of interception is low, but is always there.

« on: February 08, 2020, 1950 UTC »
If you decide on going with a 42-50 MHz bandsplit low band radio you should program these business frequencies in along with the 49 MHz frequencies:


47.4200 MHz - American Red Cross - Nationwide Primary (146.2 Hz CTCSS/PL transmit only - CSQ receive)
47.4600 MHz - American Red Cross - Nationwide Secondary (146.2 Hz CTCSS/PL transmit only - CSQ receive)
47.5000 MHz - American Red Cross - Nationwide (146.2 Hz CTCSS/PL transmit only)
45.8800 MHz - Public Safety Interoperability LFIRE4D (156.7 Hz CTCSS/PL transmit only - CSQ receive)
45.8600 MHz - Public Safety Interoperability LLAW3D (156.7 Hz CTCSS/PL transmit only - CSQ receive)

49.8300 MHz - 49 MHz FM Channel 1
49.8450 MHz - 49 MHz FM Channel 2
49.8600 MHz - 49 MHz FM Channel 3
49.8750 MHz - 49 MHz FM Channel 4
49.8900 MHz - 49 MHz FM Channel 5

Pick a CTCSS tone for transmit and receive on the 49 MHz channels.    This will cut down on interference from other users, especially on the 49 MHz channels.  I recommend programming the 49 MHz frequencies in without CTCSS on receive as well. 

60 watt or 100/110 watt VHF low band mobiles will require good antennas for maximum range.  I recommend a NMO mounted base-loaded quarter wave antenna, Larsen makes quality antennas - look into the Larsen NMO40B or NMO40C (40-50 MHz antennas).  If you're going to just use the 49 MHz frequencies for transmit and receive, you'll want to cut the antenna per the instructions for 49.8 MHz or 49.9 MHz.  Childs Antennas is another excellent company:

https://childsantennas.com/low-band-antennas

The 42-50 MHz one is your best bet. 

With 11 meters/CB and VHF low band (and all frequencies, really), the antenna is key.  A very expensive radio is worth nothing if its connected to a poorly performing antenna.   A cheap radio connected to a great antenna will outperform a top shelf radio with a crappy antenna. 

I'm assuming you're looking to buy two radios plus antennas and mounting hardware.  NMO style mounts give you the most flexibility as far as vehicle mounting options go.  It is very important that the vehicle presents a solid ground plane to the antenna.  Larger, older vehicles and trucks do better jobs as ground planes compared to smaller sedans.  However, compact cars can work just as well with some simple modifications.  I can attest to this from personal experience.  Grounding straps connecting the hood to the fender and connecting the trunk to the fender make a world of a difference.  They will make a big difference in performance even if you're using a larger vehicle, a Jeep, SUV, etc.

Peskies / Re: EE Boater's Net 4045 USB 2305 UTC 3 Feb 2020
« on: February 07, 2020, 1343 UTC »
Nice catch - there's several of these nets to be found in the 4 MHz range (4000 kHz - 4438 kHz is the marine band).  I've heard yachts in the Caribbean and Gulf of Mexico chatting away on 4003 kHz USB several times in the past (when that super strong FSK data link signal isn't on the same frequency).  I've heard what sounded like the same group on 4012 kHz USB and a couple others, including 4045 kHz. 

4 MHz and 8 MHz are pretty popular for these nets...I wanna say 8152 kHz is another popular one, but there are several others.

10/11 meters / Re: 11 meter private comms?
« on: February 06, 2020, 1918 UTC »
That's an option.

But so is buying a couple 110 watt Kenwood or Motorola land mobile radios, programming them for 43.0000, 43.0400 and the 49 MHz frequencies and using those for mobile to mobile communications.

There are lots of folks who use high power AM (100+ watts easily) for two-way land mobile purposes in the USA.  High power 11 meter freeband (especially in the lower portions of the band, 25.615-26.955 MHz) is very popular with hunting clubs and the like in many parts of the United States.  VHF low band FM gives the best characteristics of 11m but without the interference from skip (most of the time).

10/11 meters / Re: 11 meter private comms?
« on: February 06, 2020, 1606 UTC »
45auto,

Your best bet is to have multiple bands available for your communications network.  Regular VHF/UHF frequencies (the MURS channels, the FRS/GMRS channels, etc.) are good to have in a radio as well...even if you only plan on using them to monitor other folks during an emergency. 

I recommend, at the very least, that you acquire a basic 11 meter/CB radio setup - as it will no doubt be invaluable in an emergency.  Basic 40 channel AM rigs are a good place to start (for example, the Uniden PRO 510XL or PRO 520XL) but a radio that can do SSB and the frequencies above/below the CB band is better. 

The itinerant frequencies are good places to start, but be careful and be sure to monitor any frequency you intend to use. 

The 49 MHz frequencies are basically abandoned in the vast majority of places.  If you live in a rural area you'll likely be completely fine.    If you program the five channels into your low band radio you should be able to find a free frequency regardless.  The TYT quad band radio does 26-33 MHz and 47-54 MHz as "low band".  It only does FM mode though, so don't expect to be able to talk to most CBers (since they use AM or SSB mode).  You will want to use FM on the 49 MHz frequencies and any other low band frequency. 

Voice inversion provides a level of security to prevent casual interception by folks with scanners, radios that don't support voice inversion, etc.  It's certainly better than nothing. 

It sounds like you're going with the 49 MHz option.  I know I listed the frequencies previously but here's a channel plan for you:

49 MHz:

Channel 1:  49.830 MHz
Channel 2:  49.845 MHz
Channel 3:  49.860 MHz
Channel 4:  49.875 MHz
Channel 5:  49.890 MHz

If you decide to use voice inversion, program the channels in with voice inversion on and then program them in with voice inversion off - just in case you happen to stumble upon someone else using the 49 MHz channels and want to listen to them. 

Let us know what you decide to do and we can give you more guidance.  There are a lot of low band radios available on eBay (professional grade radios like Motorola, Kenwood, Vertex, etc.) - lots of sellers offer programming as part of the sale price.  I recommend going this route because these radios are very built and extremely tough.  They're also very easy to use.  You'll want to look for Motorola radios with the 42-50 MHz "split".  Other brands use 37-50 MHz, 39-50 MHz and similar "splits" to cover that portion of the VHF low band (30-50 MHz). 

411
Using the 6525 kHz - 6765 kHz range for two-way bootleg HF SSB chatter seems sort of silly to me.  There are generally plenty of clear frequencies in the 6200 kHz - 6525 kHz 6 MHz HF marine band and of course the 6765 kHz - 7000 kHz fixed/mobile band, even when the peskies are booming in from South America...will have some clear channels.   So why use the aeronautical band? 

412
Indeed.  The "40" over and over again station was kind of odd.  But 6666.6 kHz USB is sort of a home channel for the 45 metros / 45 meters crowd, sort of like 6900 kHz LSB is the home channel or calling channel for the 43m freebanders and 6925 kHz LSB is the home channel (among others) for the Portuguese speaking guys.

Peskies / Re: Not So Angry Bahstads 6224 USB 2227 UTC 28 Jan 2020
« on: January 30, 2020, 1532 UTC »
"6224 where no one can probably find us"

Love it.  Compared to, say, 6870 kHz USB or 6095 kHz USB or any of the other out-of-band frequencies they use.  There's your proof that their radios are programmed to display frequency directly.  Per the USCG website, 6224 kHz is one of the 6 MHz marine HF SSB ship to ship simplex frequencies - "shared and are not available for the exclusive use of any station", along with 6209 kHz, 6212 kHz, 6227 kHz, 6230 kHz, 6510 kHz, 6513 kHz and 6516 kHz. 

414
Nice catch.  I've heard these guys on several different frequencies, usually in the 6500-6800 kHz or so range, but they have popped up in the 6765 kHz - 7000 kHz band as well.  They seem to be fishing fleets or maybe charter services using their own "private channel" or "side channel" or general chat.  I've also heard some of them chatting with their wives or girlfriends.  LSB and USB seem to be used about equally, even in the 6525 kHz - 6765 kHz aeronautical band and the 6200-6525 kHz marine band.

*158.4000 MHz - Militia/Patriot VHF BUSINESS 26

The VHF business frequencies are taken almost exactly out of the Motorola VHF business radio manuals...including the misprint for 152.700 MHz (listed as VHF 19 or Channel 19).  The radios appear to actually use 151.700 MHz as frequency 19.  The other possibility is its a misprint for 152.870 MHz.  152.7000 MHz is not a business frequency and falls within the Part 22 paging band (the 152.690 MHz paging frequency is only 10 kHz away).  Of course, in a SHTF situation, the paging transmitters would likely be switched off and 152.700 MHz would actually be, at least in theory, a good place to "hide".

About a decade and a half ago we had a CB "Doctor" selling export rigs and linear amps from an old RV across from the local truckstop. Every day around noon he'd fire up and start playing music on Channel 19 in AM. As the truckstop sold that stuff under the counter the Doc was ran off after about six months by the local deputies. Couldn't have him walking all over the lot lizards that previously owned 19.

There’s a CB shop at a truck stop about 25 miles north of my location that advertises on channel 19, he then switches to 23 (I believe).  I’ve heard truckers ask him for radio checks, etc.  He doesn’t play music or jam 19 though...  last I checked he was running a Connex 3300 with an amplifier - although the amplifier is usually switched off - and various base station antennas.  One of the truck stops at the same exit as the CB shop has, or had, a Galaxy base station sitting behind the cashier’s area set to channel 19.  Volume turned all the way down, of course. 

The lot lizards are still around.  I’ve heard them on 19 during many a band opening.

VHF/UHF Logs, including satellites and radiosondes / Re: UHF mil air
« on: January 28, 2020, 1740 UTC »
Woohoo. Hearing traffic on 322.400 MHz, supposedly this is New York ARTCC Big Flat RGAG?  Hearing an OM assigning what sounds like local frequencies to various flights. A very strong signal.

Awesome.  There’s a LOT of stuff to listen to on the UHF mil band 225-400 MHz and the UHF military LMR band 380-400 MHz.  While not as common as UHF, there’s a fair amount of military air comms in the 137-144 MHz and 148-150.775 MHz VHF high bands (mostly AM mode) and of course the 30-88 MHz “FM” tactical band.

« on: January 27, 2020, 2310 UTC »
4662.4 kHz / 4662.5 kHz USB - another "cute" frequency (as in, easy to remember).  Like the 6.6 MHz freebanders, these stations love using the HF aeronautical bands for their private chat channel.  Doesn't make much sense to me, considering how many clear frequencies there are in the 4000-4438 kHz marine band.

OM and YL talking.  Heard a couple mentions of two- and three-digit numbers.  "105" "81" etc.  OM is much stronger than the YL.  Noting a possible third station at 2300 UTC. 

The usual tell-tale gambio heard at the end of transmission...
