Suggestions for Equipment

for New HAMs

I get asked this a lot - "What Should I Buy?" - "Where Should I Buy It?"  

First off I will share with you a link I recently received from NA7D president, Cascade Amateur Radio Society. It's all about choosing a radio. Some very good insite in it.

http://www.arrl.org/files/file/On%20the%20Air/Choosing.pdf

Another viewpoint from MARA SE web site:

http://sky.prohosting.com/n4vsp/ERC%20Equipment%20Candidates-Jan10-Narrated-M.pdf

MARA SE has seen lots of storm dammage over the past several years and so has developed communications strategies to cope with their needs. The PDF file has some great ideas for grab-and-go communications packages that can be used in the field. Don't expect to be able to afford to go with all of that at once. This is something you develope according to "your" needs for "your" area. If you are a new hame you are comming in very green. Don't be afraid to lean on the experience of others.


What Should I Buy?

The following is more related to Canadian hams:

If you get an exam pass of 70% to 79% you are a limited in that you can only work on amateur bands of 30 MHz (megaHertz) and higher in frequency. The most popular bands for that are the 2m band and 70 cm band. The 2m band is from 144 MHz to 148 MHz and the 70 cm band is from 430 MHz to 450 MHz. Those are the two most popular mobile radio bands for vehicles and hand held radios. In populous regions like the Fraser Valley I encourage my students to go for the dual band radios that have those two bands.

Why not quad band radios that include the 220 MHz band and 6m band? It's a complicated answer. Firstly, there are very few 6m repeaters in the Fraser Valley. 220 MHz band is usually reserved for interlinking between linked repeaters. And maybe most importantly - the more bands and gee-whiz gadgetry the more complicated and more costly the product. I personally yearn for a Yaesu VX-8DR but the budget isn't up to it right now. Also, it may take forever to learn how to use all of the nifty features, and then there is my failing memory which would require me to relearn over and over. You can see where this is going, back to a simple VHF / UHF (2m, 70cm) dual band radio.

Mobile or hand held?

There are always tradeoffs when making such a decision. A hand held has limited power down to 7 watts or less, usually 5 watts or less. If you are volunteering as a comunicator at an event such as a marathon and you are given a location which is somewhat remote you may wish that you had more reach / more power.

Hand held radios come with what we call a rubber ducky antenna. They are a shortened antenna for physical logistical reasons. You can improve range considerably by using an outboard antenna such as the dual band Slim Jim or J-Pole antennas or some other similar antenna. The Municipal Operations Centre I volunteer with has grab-and-go radio kits that include a take-down mast and a 5/8 wave whip with 1/4 wave radials under the whip. It works very well in the field. The kit also includes a mobile radio rather than a hand held.

Hand held radios allow total flexibility in where you can situate yourself whereas mobile radios are bigger, heavier, and have beefier power requirements. Mobile radios have more power output, usually better audio, and the displays are larger and more readable without needing glasses.

You need to determine what your own needs are. I rarely go out to an event now without my mobile radio, a portable antenna installation, an AGM type 35 amp battery in a tool bag (Canadian Tire on sale), plus I also take an Icom 91A hand held in case I need to go off station. I never have a problem being heard with that setup.

Newer radios have up to a thousand memory channels that can be programmed and some, such as some of the Kenwood TM-V71A can be programmed using the ARRL TravelPlus CD data. For people doing a lot of travelling that could be solid gold feature. I use an Icom 208H mobile and an Icom 91A and I can program them from my laptop with RT Systems software. I find that particularly handy because I can develop a channel build for one radio and copy that information to an RT Systems software for another radio. At this time RT Systems only has programming software for Yaesu, Icom, and one or two Kenwood radios.

http://www.rtsystemsinc.com/index.cfm

The Mercury BC group, here on the west coast of BC, have created a  data base of channels for several of the Yaesu and Icom radios that suits our local needs. I would suggest that if you are a member of a Mercury group and several are interested in purchasing new radios that you consider all getting the same make and model and then get a software package that can program them all. I really like the RT Systems stuff, it has worked well for me. They have just released an up grade to Version 4 and that includes ability to make use of the ARRL TravelPlus CD. Sounds great to me. Go to the web site and look for yourself.

Offshore Radios (Chinese)

I have been warning people away from buying some of the very economically priced offshore radios such as the Wouxun KG-UVD1P because I had not yet seen any official Canadian or American certification. That has changed. I was just looking for some Canadian amateur radio stores and came across this one -

Fleetwood Digital in Surrey:

http://www.fleetwooddp.com/digital/

There is an American outlet called Wouxun America who sell a slightly improved radio, the KG-UV2D:

http://www.wouxun.us/item.php?item_id=216

The KG-UV2D is almost identical to the KG-UV1D except it has a small improvement to to ability to manually program it. I recomend the 2D because the problem in the 1D is quite annoying.

Not to be undone by other high end Japanese radio makers Wouxun has come up with a waterproof dual band model:  KG-UV6D, also available through Fleetwood Digital in Surrey.

Its similar to the KG-UV2D but is weather resistant, better resistance to intermod, and supposedly more durable, all points in its favor. The price is very competitive with the Japanese competition. Still, buyer beware, you must understand that maintenance for them may be unavailable, so if you break it you may have to chuck it and buy another one. I don't know anyone close to me who has broken a hand held of any type so keep that in mind. If you look after your stuff then probably no problems. One friend had one of these Chinese radios fail out of the box and was provided with a replacement very quickly. No idea if this is normal. If it is then that's also a point in their favor.

 

In all cases, for these three radios, it appears that the batteries are the same type/model and it's a good idea to get a spare. They are inexpensive compared to the Japanese ones but appear to be reliable. 

 

 

One caution about all of these Chinese radios - THEY CAN COMMUNICATE OUTSIDE OF THE HAM BAND. To do so is illegal and it is up to the owner to be very careful in how they set up their channels so that they only communicate in the frequencies that THEY ARE  LICENSED FOR.

Used Radios

Beware of what you buy. I have purchased or been given two radios, now, that have memory problems. It's not possible to program in multiple channels. All modern multi-channel mobile radios have a lithium backup battery for the memory and that battery periodically needs replacement. Usually all you need to do is to replace that battery and your radio can once again remember channels you program in. If you or someone else inadvertently puts a new battery in backwards then there is a real possibility the memory circuitry will be damaged. The two radios I received can have "a" channel programmed in and they will retain that and so those radios are relegated to packet radio service where they sit endlessly waiting for packets of data to come by and do not need a lot of channel switching. Not a bad use for such a thing.

The point is - "have the previous owner show you that the radio works" including the memory functions else skip it. If the seller is someone who you trust then that's another matter but beware of strangers.

Before you purchase a used radio try to make yourself aware of what sort of track record the radio or amateur radio product has. I highly endorse a web site called "eHAM".  That's a site that invites hams to provide reviews of their new or used amateur radio equipment including antennas.

http://www.eham.net/reviews/

eHam should be your first stop to see what others have to say about used or new equipment. It can give you a heads up about products that have certain flaws in design that may only show up under physical stress of use, or sensitivity to being in direct sunshine, and other things that you may not have even considered. Some manufacturers provide highly inadequate warranty service or technical support. You need to know that and eHam is the place to go.

Power

The 35 Amp AGM battery I have for portable use is a small recreational vehicle battery used in motorcycles, ATV's, that sort of thing. It's powerful enough for any of my temporary mobile needs. It's sealed and I don't have to worry about adding water or gassing that would smell up my radio room. AGM batteries are what are being used to replace the gel cell batteries we were used to using for similar applications but are more efficient.

I also have a sealed 110 Amp AGM battery for my radio room that is used to power up my HF gear and other equipment requiring 12 volts to operate. It could even power a linear amp providing I didn't spend too much time talking. Both batteries are charged simultaneously and maintained by a relatively low power intelligent charger designed to work with AGM batteries. I find it much better than using the regular big AC power supplies and it's there, too,  if the lights go out. My large battery is connected to an MFJ-1126 40 Amp distribution panel and it has Anderson Power Pole connectors on the front. All of my HF and mobile radios now have Power Pole connectors on them as do my vehicles. I can move my dual band Icom 208H from home to truck in only about 2 minutes.

Take a look at this for some ideas:

http://home.comcast.net/~buck0/app.htm

http://www.qsl.net/w2vtm/powerpole.html

In the brochures a tool for installing the connectors is mentioned but I'm not a fan of that method. I've heard of too many failures of wires pulling out. I prefer to use a small soldering iron to install the connector onto the cable. Whatever you do be careful about how you solder. If you are at all shakey get someone else to do the job, you don't want any solder to get onto the contact end. The contacts are silver plated and the solder flows on very well. One good thing about soldering the connectors is that I can reuse them whereas if I crimped them I'd have to cut them off and throw them away.

For the home you can also use a power supply for your radio power needs. There are two basic types, one we call analog and the other switching. Once again we have important decisions to make. Analog supplies are heavy for the ammount of current they can source. They have large iron core transformers in them. The good thing is that they are a quiet source of power, they do no produce electrical noise on their output side (not usually anyway).

Switching supplies are quite light in weight. If you have had a series of microwave ovens over the past 30 or more years you may have noticed that the old ones weighed quite a bit and were a bit of a chore to move around. The new microwave ovens are so light that if you accidentally slam the door the whole oven moves backward. That's because the old ones were using old technology requiring an iron core transformer. The new power supplies using switching technology and I won't get into the details other than square waves are produced in the switching process and whenever you create sharp voltage and current transitions you generate RF noise. Well made, military grade, switching supplies have excellent filtering on leads going in and out of the power supply boxes so no nasty noise gets out. Cheap power supplies often have noisy RF leakage that can disrupt HF communications. I have even heard of switching supplies that have generated enough noise to cause FM radios to desensitize and become deaf.

Generators

If you choose to have an AC power supply to run your equipment then you need to have some sort of backup power in case you lose power from the grid. I recently purchased a Champion 3KW generator (4KW peak), with wheels, from Canadian Tire when it was on sale ($300), virtually the same price for the same generator at Costco at their regular price. I have tried it out and it seems to work quite well. Pretty amazing what those industrious Chinese are cranking out these days. Costco also sells a 2KW generator (no wheels) for about twice the price of its bigger brother but it's way quieter and it has inverter circuitry to provide perfect 60 Hz frequencey output and constant voltage. It would be perfect for any of your electronics except for a big linear. That may load it too much. It can run a medium size microwave or other loads. It could take care of camping needs without slurping too much gas or making you an enemy of other campers. With a computer, a multimedia projector, a screen, and some good movies you could be a hero with the kids while camping in the back woods.  :-)

  Antennas


Mobile Antennas -

You will want an antenna that suits your needs. The ideal location for best signal distribution is square in the middle of your roof but this is impractical for most of us. Parking in underground parking or on board ferries there is a high probability that our antenna may be wiped off. Short antennas like 1/4 wave whip antennas are alright around town but the gain of the antenna is low. The best mobile antenna seems to be either a 1/2 wave or a 5/8 wave whip and they are usually mounted on a fender (various ways) or on the front lip of a trunk lid. Some antennas made by Diamond Antenna are designed to release and lay down if you wish to go into underground parking or on board the ferries.

The 2m whip mentioned in the above paragraph can be mounted on a magnetic mount and I enjoy using one.  I just used mine on a vehicle used in the Royal Victoria Marathon. I got power for my mobile radio through a cigarett lighter plug and set my transceiver onto low power. With the significant gain of the 5/8 wave whip I was able to stay in touch over the whole route. After the race was over I was able to take my equipment out of the lead car in under two minutes. Very handy. Since writing that item about plugging into the lighter socket I have hard wired with a pair of flexible 10 ga. wires to my battery terminals via a pair of fuses. The wires come to a space between the seats, same place as my antenna connection. The ends are fitted with Anderson Power Pole connectors same as a pair coming out of my radio. I don't leave my radio in the vehicle. When I take it out it's only temporary. Most of the time it's hooked up in the ham shack via the same sort of power pole connectors.

Another thought about roof mounted radios is regarding resale value of the vehicle. If you have an older vehicle a hole in the roof with a snap in plug will likely not reduce the value appreciedly whereas a hole in the middle of a newer vehicle may turn a prospective buyer right off. Many of the new fender or trunk antenna mounts can fasten on in such a way that there is little evidence left behind after the antenna has been removed.

 Further to this is that if you have a dual band radio you will need a dual band antenna. There is quite a sellection to choose from. I won't elaborate beyond what I have mentioned. My favorite antennas are ones which mount on a right angle mount on a fender. I'm not fussy about mag mount antennas but do use them in situations like when I had to be a communications person in the lead car of the Royal Victoria marathon. I plugged into the cigarrette lighter socket, put up my 5/8 wave mag mount, and was ready to work. It must now be evident that what you equip yourself with should be related to your actual needs. That's the tough part, knowing how to be prepared for every eventuality.

 Base Antennas (Fixed Station) -

 The radios I am recommending are dual band radios with the VHF 2m band and the 70 cm UHF band. This is a pretty common package and so dual band antennas are also common and easy to purchase.

Comet  and others makes several dual band base antennas and most have a fibre glass shell to protect from the weather.

- Comet GP-3

-Comet GP-6 dual bander with 6 dB of gain

-Comet GP-9  dual bander with almost 9 dB of gain (about 20 feet long)

These Comet antennas get progressively more pricey as their capabiliites go up and taller.

So far so good with the Comet GP-6 and GP-9's my group have been using. Very good reviews on the GP-9 from a lady friend who has a Yaesu VX-7 5w hand held radio and who regularly goes on a simplex net and often leads it. She's as solid as any one of us using our mobile radios.This lady regularly works a repeater approximately 100 Km away using her Comet GP-9. I think that's terrific.

See details on the NCG Comet antennas at:

http://www.cometantenna.com/products.php?CatID=1&famID=5&childID=4

Another dual band base antenna that may prove to be better than the ones in the Comet line is the Diamond X200A. It too is a dual bander and eHam reviews look very good for it.

Last but not least is a simple but very good antenna made by Arrow Antenna. The one I'm thinking of is the J146/440 solid element, open stub, j-pole antenna. It's a dual band 2m, 70 cm antenna. Very economical yet works very well. Very sturdy construction. Can often be mounted on toilet/drain vent pipes on roofs and the coax run through a roof air vent, the whole thing becoming a stealth antenna installation. They have been installed in many restricted covenant building locations without complaint. If the building roof is a peaked one with duroid shingles the antenna can be totally stealth, it can be mounted in the attic.  Look in the Antenna page of this site and look for instructions on building an equivalent to the Arrow J146/440. One thing to realize is they do not have high gain and so may not be adequate for your emergency simplex operation needs.

Check with your ham radio supply store/s for pricing and suggestions. They want you to be a happy customer so that you will return. Consider the breakdown possibility and need for repair.

Icom has a depot in Richmond.

Radio World has a repair facility in Toronto and do service on the equipment they sell.

If you want a great price on a Yaesu and fast service is not a consideration then you may consider US stores like HRO in Portland Oregon. They have some great prices. Be warned about any Japanese made radios sold in the US like the Yaesu and Icom models. Canadian shops will generally not honour the warantees if purchased out of Canada. The equipment will need to go back to the US for service.


Check out swap and shop listings on line and used equipment on eBay.

O/K so much for the antennas you can purchase. Lots to choose from. Don't think that you can't come up with some pretty decent home built antennaas yourself. If you choose to build your own (See the antennas section of this web site) be careful. You can wreck the final in your radio by transmitting into a bad load. The best solution is to be a part of a group or even to have a friend who has an antenna analyser. You can use that to determine if the antenna is correctly tuned or not and if not then it can assist you in getting the antenna to the right resonating  length. In my case I won't lend out my analyser but will go along with it to help someone. I've seen too many club owned analysers smoked by beginners who thought that transmitting into them would tell them the power output of their radio. Yes, it happens time and again unfortunately.

Why do I Need Certification to Operate in an Emergency ?

There are several reasons. Under normal circumstances your equipment could be confiscated and you could be fined. Outside of that there are operating protocols used by certified radio amateurs that are followed, if not by law then by convention - standards that we all have agreed upon locally and internationally. If you get on the air and start jabbering without using correct protocols you would imediately be recognized as a fraud, even during a disaster and may be looked upon with skepticism . This means that if you are actually trying to report a life or death problem you may be looked upon as the boy who cried wolf. It does not hurt to take a full size course, actually learn how you are expected to behave, how to talk, how the radio and antenna and feedline works. Become a respected member of the amateur radio community.


Doing Your Part

Consider joining your local municipal or city emergency preparedness group. It speaks volumes about who you are and your intent when you become a conscientious volunteer.

Have you joined RAC (Radio Amateurs Canada) ?  That is the Canadian agency responsible for being our liason with government and with other amateur radio groups here and around the world. If you subscribe to them you get to be a member plus they send you a bimonthly magazine called TCA (The Canadian Amateur).  Cost of membership is running at $52.50 a year. By subscribing you are helping  to support a very useful small organization that helps all Canadian hams.
