Title: HAM guys, what do you think of this one?
Post by: Kodiak Commando on August 08, 2015, 12:58:26 PM
Here's a link to a radio I'm thinking about getting.  Opinions?

That doesn't do 2 meter (other wise known as 144MHz) which is the most common repeater in our area followed by 70 cm (other wise known as 440MHz).  Some recommendations are:



These are ones I have experience with.  I have 2 of the older version of the icom (ic-2100) because the price was right. I have one of the Yaesu ft-2900.  They are both excellent radios.  Rusty has a kenwood which is a good radio, I just don't have any experience with them.  I will let other guys post up what they have and their thoughts.

I think this is the one Rusty has.

Check out the prices here.  They are cheaper than amazon.

Hey Fred, that's a nice rig! Sure is purdy! I read the review of that radio and did some research. The Magnum S-9 175 has the ability to transmit from the 10 to 12 meter range (24 to 29mhz) which includes CB. Using the Export mode and adjusting jumpers 1 through 4, you have even more frequencies (26 to 32mhz). The built in 100+ watt amplifier is a nice touch also! May get hot in the Jeep though. Two mic plugs is a bonus when installing this little gem! With the 10 meter band and CB coverage you can shoot skip and talk all over the world! That's a pretty sweet little radio!

Out of the box it is 10 meter, right? The 10 meter band, just above the 11 meter band, or CB (27mhz), requires an FCC license. If you read the last paragraph under 'Testing and Output' in the review you posted, you'll see he is a licensed Ham radio operator. In my opinion, if you're planning to get a license I would suggest starting with 2 meter Ham radio like Jacob suggested. Not only will you have access to repeaters all over California and elsewhere, which allow much greater communication ranges, but they're more widely used and monitored too. Most recently, using 2 meter and the Oakhurst repeater (Deadwood 147.180mhz), I was chatting with Dave (TokyoTaco) on the Dusy Ershim trail from our home in Clovis a couple days ago. I've never played with 10 meter before so I couldn't tell you have much range they have. I did check repeaterbook.com for 10 meter repeater coverage in California and there aren't that many (closest is in Madera 29.68mhz). And at that price, you could buy a dual band (2/440 meter) radio, that's smaller in size, have more repeater coverage, and have twice as many people monitoring the frequencies. But I could also be wrong about 10 meter, it could be ubiquitous and I could be missing out! Checkout the Ham Band Frequency allocation and acquaint yourself with what's legal in the USA and what's not.
Just my 2 cents Fred!

I was asked to make a few quick comments.

First off this radio was an amateur radio. This radio is modified to use cb thus not part 95 compliant. (http://www.gpo.gov/fdsys/pkg/CFR-2009-title47-vol5/pdf/CFR-2009-title47-vol5-part95.pdf) Some radio companies tried to push the limits of CB range and that included the use of Single Side Band (SSB) vs AM as most refer to as CB radio. Many people think that you do not need an FCC license to use a CB. This is not true. FCC basically made it so that one needs only purchase a “certified” cb radio to be compliant thus implying you are following the rules (fcc.gov/encyclopedia/citizens-band-cb-service (http://fcc.gov/encyclopedia/citizens-band-cb-service)).

Next, to get the radio frequency skips that this person is describing on a regular basis, you would have to have a minimum ½ wave antenna. This means you would need a 5 meter or 16 foot antenna. Even if you had 100 watts like this radio (Not part 95 legal) and use ¼ wave antenna that would be 2.5 meters or 8 feet. Not very practical. 11 meters or CB radio Band, that use fire sticks, coil the antenna to make it physically longer in a shorter space, but not electrically longer. Wilson whips (102 inches) do get skips but not on a regular basses and usually during sporadic E layer in ionosphere. 

Next, this radio is not designed for repeater use, strictly simplex. Other than it is not compliant with part 95  it is also not able to transmit or receive off set radio frequencies as required for 99% of most repeaters. There are some repeaters that use what are called “simplex repeaters” that use the same transmit and receive RF but they are rare. This radio doesn't have the ability to program a private line (PL) tone, either Continuous Tone-Coded Squelch System (CTCSS) (https://en.wikipedia.org/wiki/Continuous_Tone-Coded_Squelch_System) or Digital Code Squelch (DCS) (http://wiki.radioreference.com/index.php/DCS) which most repeaters require to access them to repeat the signal.

If your goal is a stronger cb radio than this will do it, but this is not part 95 compliant and not many cb radios have SSB so you are limited.
If your goal is an amateur radio, then go with a 2 meter rig like Tony and Jacob stated. I use both cb and amateur radio, but I do not mix the two. CB is good to communicate with those without an amateur radio license and amateur radios get the distance by repeaters, but both are legal and separate.

Hope that helps.

Side note, using 100+ watts of power usually requires 22 to 25 Amps duty cycle. This means minimum 8 gauge wire and not to mention there is a reason for such large heat sinks on this radio. It will be a nice leg warmer. It is better to have a higher gain antenna tuned to the frequency than trying to push that much power to a compact antenna (firesticks). Your SWR will be off the charts and even if tuned correctly you will have high loss because of RF feedback. So you may be pushing 100+ watts but your antenna RF radiation will be more like 40 to 50 watts.

Thanks that is good to know.  Sounds like if you use it too much it will self destruct. 

Are there any other 2m vehicle radios you would recommend?  I think I just want to put together a list of good options of vehicle mounted 2m radios and good antenna brands to look for.

I have a Kenwood TM- 281A in the YJ and a Icom like Jacobs in the TJ.
Nice thing about the Kenwood is it's 75 watts on the high side.

Hey Fred, don't keep us in suspense what did you go with? The Magnum or something else?

Bump for those looking for ham radios.  The prices have changed a lot but look for radios in the $120 to $160 range.
