A feature-packed shortwave radio made for worldwide travel
Made especially for the world traveler, the Globe Traveler G3 packs many features into a classic short wave package. Tune into AM/FM/Shortwave, Single‐side band and Aircraft band. The integrated RDS (Radio Data System) on FM shows frequency, call letters, artist name, song title and date on the display when available. There is also a synchronous detector with selectable side‐band and 700 random programmable memories for all frequencies. A telescopic antenna works to find the best reception for FM and shortwave, while the internal ferrite bar antenna reaches for AM reception.
An innovative portable radio
The G3 features RDS (radio data system) on FM radio. RDS, on the LCD screen, displays frequency, call letters, artist, song title, date, messages in display when available. The LCD display also indicates time, alarm clock, frequency, stereo, sleep mode, lock, battery level, memory, time zone weekday, signal strength and RDS. If that's not enough, the G3 plays your MP3's, too. With 700 randomly programmable memories for all frequencies, you can't get enough listening with the G3.

Top customer reviews
I've been using the G3 for several days now and over all I'm pleased. It's plenty sensitive, easily picking up everything I can find on my classic SX-190 tabletop. AM/FM broadcast band sensitivity seems quite good as well, at least as good as the radio in my car. Additionally, with a major airport about 30 miles away the air band picks up a lot of commercial air traffic loud and clear. It's fascinating to hear a jet fly overhead, catch the radio chatter and hop online to find what the flight is and where it's going. Tuning is continuous throughout the range from broadcast all the way through the shortwave band and the combination of direct entry, rotary encoder knob and auto scan makes tuning a snap.
- Very compact unit, clean logical layout
- Nice fit & finish, feels reasonably solid and includes a padded carry pouch
- SSB support, a handy feature that is absent from most portables
- Good audio quality, ok so it won't rattle the windows but it provides a lot of volume for such a small package
- Nice long whip antenna
- Includes external antenna jacks, both line out and headphone jacks, as well as line-in which is of questionable usefulness
- Wide coverage, air band is a nice touch
- Capable of charging NiMH batteries internally from the AC adapter
- Buttons are NOT backlit, this is a definite step back from the discontinued G5 this replaced
- Volume control is digital pushbuttons, I would have preferred a real knob
- No way to keep backlight on indefinitely when operating from batteries. Will stay on when on external power though
- Rubbery texture feels nice but really shows finger smudges and is easily worn off edges
- Table stand is a bit short, I'd prefer if it stood the radio slightly more vertical
- No squelch control. To be fair I've never seen a portable with squelch but it would be nice for the air and CB bands
- Clock/date settings lost when batteries are removed, minor but annoying. Station presets are retained at least
- Tuning knob is a bit small, has no weight to it and has a lot of grippy bumps on the surface. A single dimple would have been easier for twirling through the band. Understandable compromise for a compact portable though.
Update: I found the lack of backlit buttons to be the biggest flaw in this otherwise excellent radio. It really makes a big difference when trying to operate it in a dark room, especially if you want to use this while camping or during a power outage or other emergency. Noticing how similar the radio looks to my friends G5 which DOES have backlit buttons, I decided to open my G3 and have a look. It turns out there are pads on the keypad PCB for three SMT LEDs and they are even wired up with the necessary resistor(s). Everything is there, they just skipped out on installing the three LEDs to save a few pennies. I had some tiny SMT white LEDs on hand so I soldered them in place, reassembled and now I have backlit buttons! The light is not terribly even but is sufficient for operating in the dark. Note that this modification is not for the faint of heart. You WILL void the warranty on your radio, and risk ruining it in the process. I used 0803 sized LEDs which are a fraction the size of a grain of rice and while soldering them you must take care not to melt the surrounding membrane keypad. DO NOT attempt unless you are experienced hand soldering tiny surface mount components and can afford a new radio if you manage to wreck this one.
My background in electronics started ca. 1946. Got my Amateur Radio license in around 1954, my pilots license in ca. 1970, have been involved in radio, flying and general electronics and systems since. I'm sharing this personal info with you so you'll know from where I get my viewpoint in looking over technical products.
Before I purchased this, I looked the product up via an Internet search and found a link to the manufacturer's Website, from which I downloaded a .pdf copy of the Owner's Manual. I'd strongly encourage anyone who is contemplating purchasing this radio to do likewise, as the printed manual that comes with the radio is fairly small and having all of the info available on a computer screen is much easier to deal with than the paper manual, especially when the radio is new to you.
On unpacking and setting up the radio, I was very impressed with its appearance; the finish is a matte black and it resists fingerprints better that a glossy finish would. The controls are solid-feeling and all of the buttons provide a firm and obvious tactile feedback. The display is absolutely first-class. Sharp and easy to read, even at an off-axis position. The back-light is good - if you are using the radio with batteries it only stays on for around 10-seconds. However, if the supplied power supply is plugged in and energized the display stays on until the `Light' button is pressed again.
I happened to have a supply of Eneloop AA Nickel Metal Hydride batteries and elected to install the required four. The instructions seemed to me a little vague regarding the charging procedure and I wrote to Customer Service about the possible risk of over-charging the batteries. Received a reply "Our factory Engineers say that the battery will completely shut off charging once fully charged, regardless of when charge is started", which satisfies my concern.
If you remove the batteries to charge them externally (which I did once with the Eneloop charger) you will lose your clock settings and the day-of-the-week indicators, but other settings and stations you have stored in memory seem to stay unscathed. If you plug in the power supply, you can avoid the inconvenience of having to re-do the lost settings. If worried about line power failure, while the power supply is connected you could insert a set of alkaline batteries while the power supply is running and plugged in for extra insurance.
Now, on to the bands it receives. There is a very low frequency band starting at 150 KHz and ending at approximately 570 KHz, where the `broadcast' band begins. The frequency coverage extends continuously all the way to 29.999 MHz. Just a few notes here, as the manual does a very good job in covering the various bands.
The low band starting at 150 KHz was once populated with Non-Directional Beacons used for aircraft, and likely marine, navigation. As far I can tell, most of these have been de-commissioned and there is only one that I could find remaining in our area West of Washington, DC. and associated with Washington National Airport. If you are curious, one source is the Aircraft Owner's and Pilot's Association, where you can search for airport information and find all sorts of current frequencies for navigation and communications.
Concerning aircraft communications, the best source of frequencies is probably the `airports' info on AOPA where you can see actual legal and current airport information with Tower, Departure, Approach and many other frequencies. Living near a major airport should yield numerous communications exchanges. A word here, though. In order to keep channels clear of chatter, most communications are very short and it will take some getting familiar with to understand what it's all about. Leaving the radio tuned to a frequency that you expect should be active for a while is likely to produce some short transmissions.
Another good source of frequencies worth knowing about is the Amateur Radio Relay League, where you will find all of the `ham' bands and the classes of operators allowed to use them. You can learn Morse Code if you like. And you can listen to Single Sideband transmissions and conversations between amateurs.
As the manual clearly states, lower frequencies usually provide much more action during the twilight, nighttime and dawn hours, while higher frequencies are more active during daylight. Also consider that it will be dark in London, England 4 or 5 hours earlier than on the USA East coast, as an example. I have picked up stations in Mexico on the broadcast band at night.
There are a number of time standard broadcast stations you can use to set clocks and watches close to atomic accuracy. The one I use most is CHU Canada at 3330 KHz and WWV in Colorado at 5000 KHz. These are best early in the morning. You can find many more frequencies on the Internet.
Now to FM. This radio has proven more sensitive on FM than any other radio I have owned, picking up a difficult classical music station in the Baltimore area with the antenna barely extended, where a radio costing over twice as much can't compare. The audio quality is good - speaker is better than usual. There is a headphone jack and with a good HiFi headset the audio is excellent. There is also a Line In/Out jack, which I connected to a HiFi Receiver driving a good set of speakers and found the audio quality most excellent, probably as good as the FM tuner built into the HiFi receiver.
There is an external antenna jack, and if you are really serious about listening to shortwave radio, a really good external antenna should help immensely. There is a built-in antenna for low-frequency use as well.
Interference. Especially on the lower frequencies such as the broadcast band, there are numerous devices that produce interference - often mush stronger than the signals you wish to receive. The most common would be fluorescent lights and power line noise. As you tune higher toward 30 MHz, these problems are reduced, but still can be a nuisance. I happen to have a compact fluorescent lamp behind the chair where I usually sit to listen to the radio and if the CFL light is on, it renders the lower frequencies un-useable.
Another thoughtful and superior feature is the `Lock' function. If you engage this while listening to a station, an accidental bump to the tuning knob won't de-tune the radio - you get a `HOLD' message instead. You can also fully lock the radio so that basically nothing will work until you un-lock it. That is very helpful when moving the radio.
You can store up to 700 station frequencies - not the usual 5 or so available on most radios.
A few of the functions are a bit hard to do because the time allowed between steps seems a little short - like setting up alarms. There are four of them and you can set each one differently, like the times and days of the week on which you want the particular alarm to work. There is also a `sleep' function. The difficult programs are probably good as a means to keep one's mind quick and nimble - and you need to keep the manual handy. If the radio is ever re-engineered, perhaps a little more time between steps would make the product a tad more user-friendly. I'm not complaining- just observing. I think the radio is an engineering masterpiece as it is!
