Basic Comms - Level 1 - Portable

fedorthedog · Dec 26, 2015

I cant remember which way this goes but my buddy who is a ham cut a wire in either his GRMS or his Baufeng and it allowed it into the other radios freq band, making it multi use, . Maybe one of the techs like BT will be able to advise further.

Hey @fedorthedog, Yep. Most of these consumer Radios, are just rebranded Commercial Radio designs, that are Band Limited when sold into the non-commercial Markets. My two Kenwood TH-D72As were locked on the Ham Bands, when purchased, but within 20 minutes of acquiring them, I had the Backs off, and the Chip Resister removed to give them Full Frequency Bandwidth capable.
(100 - 170 Mhz & 400 - 520 Mhz Tx/Rx) I did the same with my three Kenwood TM-D710As. (Base, Rhino, and Red Toyota 4X4)
All have 1000 Memory Channel Capability, so I have them loaded with ALL, the Marine, Aircraft, Public Safety, MURS, FRE/GMRS, Ham, and any other Frequencies, that I might need to monitor, or communicate on....

Note Here: In some States it is ILLEGAL to posses a Receiver, in a Mobile Vehicle, that can monitor Public Safety Frequencies...
It is NOT ILLEGAL to POSSES a Modified Radio, HOWEVER, it is ILLEGAL to Tx, on ANY Frequency that you do NOT hold an FCC License, to use... FRS, CB, MURS, and non-Commercial Marine Vessels, & Aircraft, are covered by FCC Blanket Licenses that cover ALL Us Citizens, and Landed Resident Aliens....

@BTPost I didnt understand this part. Could you elaborate?

"...Modified Radio, HOWEVER, it is ILLEGAL to Tx, on ANY Frequency...." what is Tx?

AD1 · Dec 26, 2015

Tx= Transmit

Rx= Receive

So when are you getting your ham radio license?

I know someone in Tempe that can help

Transmitters can be made to transmit on any particular frequency, and commercially available units are arranged to prevent transmission off the allocated spectrum. (Amateur radio is allocated parts of the radio spectrum, and is not allowed to transmit outside of those frequencies.) BT is talking about very easy modifications to transmitters that enable transmitting "out of (allocated) band" which is illegal and costly if caught.

TX is transmit and RX is receive. Out of band transmissions, especially those that interfere with other services will have the FCC knocking on one's door.

Ham rigs with transistor RF finals include a general coverage receiver. That means they transmit Ham bands only and receive from 500 kHz (commercial AM radio) to 30 MHz. To unlock them so they transmit or receive from 500kHz to 30 Mhz requires cutting a diode. As I was involved with MARS or Military Auxiliary Radio Systems my rig's diode was cut. My rig is also modified to switch the fan on about 10C earlier and some other tricks.

Thanks @AD1 and @Tikka I just didn't understand what 'Tx' stood for.

Tikka · Dec 27, 2015

@Ganado
The second paragraph was more for others.

If and when SHTF, being able to go where the average person can't will be an advantage.

Well, I was bored today and thought I’d post something of substance, and contribute to the board. I thought I’d outline how I have my comms setup and maybe give people some ideas about their own comms. This post will about first line comms, or Level 1. This is a system I used to try and keep everything organized. All of my preparations basically involve 3. So I setup my comms systems the same way. I figured I’d outline what I considered Level 1 comms. Level 1 comms is small, hand held and portable. Let me know what you guys think.

FRS/GMRS: I think everyone should have at least a couple of FRS/GMRS radios lying around. These come in handy for all kinds of things. They are pretty cheap and simple to use. I would recommend going with the Motorola’s, just my personal preference. I think the Motorola’s have better antennas and are more reliable. If you’re really serious, you can get commercial grade radios from Icom or Yaesu that will blow the “store shelf” stuff away any day. But they’re also 3-4 times the price of the store radios. I went with the Motorola’s simple because I have a Yaesu HT (hand held) radio already. But I’ll get to that later. I also prefer that the radio use rechargeable AA’s and NOT the one’s with rechargeable battery packs. Reason being that I’ve tried to standardize on the same size batteries for all my comms equipment. I have several trays of rechargeable batteries of all different sizes along with a way to charge them. This also makes logistics easier, if my FRS radio dies I can take the batteries out of the scanner. Something else to remember, FRS/GMRS are basically “line-of-sight” radios. Meaning if your trying to talk to someone on the other side of a mountain, you most likely won’t be able to communicate. The higher you are, the better your “line-of-sight”, and the further you’ll be able to communicate with someone. We have a long-standing rule in our group for when we are ATV’ing, hiking, camping or hunting. If someone gets lost or separated from the rest of the group, try to get to the highest point you can. It will make communications easier. FRS radios have a maximum legal limit of ½ watt. No license is required for FRS. GMRS radios have a maximum legal limit (for a HT) of 5 watts. You need a license for GMRS, which you get from the FCC. You basically download the form from the FCC’s website, fill it out, and mail it in along with a check. The FCC will mail you your license. I don’t remember how much the fee is, but it’s pretty cheap. I have several FRS/GMRS radios for the family and all my neighbors and friends have some also. There is also a business band that is similar to FRS. It’s called MURS. I’ve left MURS out as it’s not very widespread in my area and equipment is still limited. It’s also readily available in stores like FRS/GMRS is.

SCANNER: This is the 2nd most important item in my comms setup. Why, it allows you to know what is going on around you. For Level 1 comms, I recommend a handheld model. Level 1 equipment needs to be portable. I would recommend checking to see what type of communications your local Fire, Police, EMS and airport are using for their system. For example, most of the Police (State and County) in my area use a Trunking system. A Trunking system allows multiple agencies to use shared frequencies without interfering with each other. For this reason I went with a scanner that had the Trunking feature. Again, determine what you need based on what is being used in your area. With the information on what was being used in my area, I went with a Radioshack Pro-95 scanner. It has multiple memory banks and uses AA’s. I have my scanner setup for Fire, EMS, Local Police, County Police, State Police, Sheriff, FRS/GMRS, CB, Air and several HAM frequencies. This gives me a nice compact package that I can take anywhere and be able to keep up-to-date on what’s going on. In the event of an emergency, it is going to be vital that you have the right information on hand. Having the right information on hand will allow you to make the right decisions to determine the course of action you take. During the great blackout, being able to monitor the situation in town was vital. Knowing what was going on kept me, and my family, from worrying too much.

AM/FM/SW: Another important piece of equipment is a good AM/FM/Shortwave radio. Reasons are basically the same as for the scanner. Being able to get information on a situation. I highly recommend the radio have shortwave capability also. Being able to pull in foreign stations can sometimes give you better information. Shortwave also gives you a different perspective on the situation. During the “great blackout”, I had the Shortwave tuned to the BBC. The BBC seemed to have a better idea of what was going on in the US than we did at times. Remember, the point is to get as much information as possible. Usually the best way to do this is to get information from multiple sources. I picked a Grundig FR200 as my Level 1 comms for this area. It has AM/FM/SW, built-in light and a hand crank for recharging the battery. I have been very happy with this unit. So much that I purchased several, and gave them to friends for Christmas last year. It will also operate off of AA’s. I like the built-in generator that recharges the battery pack. You don’t have to worry about finding the batteries dead when you go to use it. I think it’s a great radio and sells for about $30 now. I HIGHLY recommend an add-on antenna for it. The stock antenna is not that great for SW. I picked up a small wire antenna that is contained in a reel. It has a clip on both ends. Simply un-reel the wire, clip one end onto the existing Grundig antenna and clip the other end to an object as high as possible. This little gadget cost $20 at Radioshack and GREATLY improves reception.

CB: I think everyone pretty much knows about CB. So I won’t go into much detail. I have a couple hand held CB’s that I use every once and awhile. There really is not much traffic in my area on the CB bands. But it’s nice to have around if it’s ever needed. Just remember to try and get one that can uses AA’s or whatever other battery size you standardize on.

HAM: This is Amateur Radio. HAM’s have been around for decades. They provide emergency communication during times of need. HAM’s are licensed by the FCC, and have their own set of frequencies (bands) that they can use. I won’t go into details about Amateur Radio, tons of information can be found online. I’m covering this at a very high level so that you can get a basic overview. You need to take an exam to become a licensed HAM. There are 3 levels of testing, Technician/General/Amateur Extra. You must pass a test to move to the next higher class. The higher your license, the more operating frequencies you have available. To keep things simple, HAM radio has 2 basic frequency categories. There’s VHF/UHF and HF. There are allot of other different categories, but I’m trying to keep it simple. VHF/UHF is the range of frequencies that FRS/GMRS, police, fire and EMS operate in. HF is the range of frequencies that SW operates in. The VHF/UHF frequencies are pretty much “line-of-site”. Frequencies in the HF spectrum can travel for thousand’s of miles, much like Shortwave does. I’m going to stop there, I don’t want to get into too much detail about Amateur Radio. If anyone is interested I can point them in the right direction to get information about this hobby. HAM equipment gives you a much broader range in which to communicate. There are repeaters throughout the country that will boost your signal and allow communications on VHF/UHF to take place over a much greater distance than FRS/GMRS. Using my HT, I can use the local repeater to talk to people in the next county. For your Level 1 HAM equipment, I recommend a good HT. They have a max transmit power of 5 watts. There are several out there to choose from. I went with a Yaesu model that covers 3 bands in the VHF/UHF spectrum. The radio covers 6m, 2m and 70cm. Each band has it’s plus’s and minus’s, and depending on the situation I can choose the most effective band to use. The model is the VX-7R. It’s waterproof (to an extent) and is very rugged. No matter which model HT you get, there are some accessories that I think are a must to have. First you should have several spare battery packs for your radio. An external speaker mike is another good accessory to own. You can also purchase various different antennas for your HT. Some antennas are short and small for ease of portability. Others are quite big, but offer greatly enhanced signal performance. I have several for my HT, one being a short stubby antenna for when I’m really close to a repeater or another HAM. The other antenna is pretty long, but gives my HT a signal boost for those times I’m not close to any repeaters. I also purchased an AA battery tray that allows you to use AA batteries in the HT for emergencies.

POWER: The final part to this long list is power. What you’re going to need to run all these electronic gadgets. This is the most overlooked part of the system, while I think it should be considered top priority. I based my Level 1 gear around mostly using AA rechargeable Ni-MH batteries. All of my Level 1 equipment can use AA batteries. I have an AC charger for charging the batteries, as well as several DC chargers. The AC chargers are for use in the house, hotel or with a generator. DC chargers come in different forms. I have some that work off of the cigarette lighter in my truck, or off of a solar panel. I have two Brunton SolarSport 2.2 solar panels. These work very well for charging rechargeable batteries. I also recommend some AC-to-DC converters. These will allow you to run the equipment that requires DC, from an AC outlet. All of these different chargers are pretty cheap. I got mine from Radioshack. I recommend having atleast TWO different ways to charge/use your equipment, three is even better. During an emergency, there is no telling what type of power you will have access to. Try to have as many options as possible. Remember Murphy’s Law. Having AC, DC and solar charging options means you will most likely always have comms available.

Well that pretty much covers Level 1 comms. Everyone’s needs are different, so pick what works for you. I have portable equipment to cover all these areas. What I have might seem a little overboard, but communications is my hobby. Some might only need/want 1 or 2 different forms of communications. So choose what works for you. Also make sure you test your equipment and practice with it.

Thank you, some of your suggestions as to CB radios are interesting. Something I never considered. My dad one in his Jeep, their club used them for years.

Just picked u one of these Midland portable radio's to throw in my company truck. It adds another layer of comm's, when on the clock away from home. Having the Weather channel is a great tool around here since our patterns are continually changing.

It can either be used off the trucks power or I can throw the standard/ rechargeable battery pack on it and add it to my GHB kit if I have to move on foot. I added an external truck antenna as well for the extra range. The stand alone unit's antenna is short range of course and has it's limitations.

Motomom34 · Jan 23, 2016

I just watched this video last night.

His top ten communications were:
1. Cell Phone
2. Multi-Band Scanner
3. AM/FM Radio
4. Weather Radio
5. Shortwave Radio
6. FRS Radios
7. GMRS Radios
8. CB Radios
9. Marine
10. Ham / Amateur Radio

He broke the communications down into receive and transmitter. He seemed to really like the multi-band scanner though emergency personnel are using encrypted channels so I am wondering if the multi-band would be as informative/effective.

Yard Dart · Jan 23, 2016

I like to use my scanner and I do pick up quite a bit of traffic. But like most major metro areas, the most interesting channels are ususally encrypted.

Now if SHTF, it would be a vital tool to pick up any unsecured comm's..... but like any tool, you nee.d to know how to use it in advance or "troubles".

Motomom34 · Jan 23, 2016

@Yard Dart so a scanner is a good investment and would be truly be a valuable tool in your opinion? I have about half the list in my post but I am feeling like a pack rat...... lots of stuff for just in case.

Yard Dart · Jan 23, 2016

There pretty cheap....get one.

as1mov · Jan 21, 2019

I've a couple of 'Presidents' a Lincoln #1 and a Jackson #1. The Jackson has been modded to give UK40 FM and output 30W on 10mtrs.
I keep both in a 'Faraday' box' when not in use. 'JUST IN CASE' hehe
