Sangean MMR-77 Emergency AM / FM Portable Radio Review

(More customer reviews)Sangean MMR77

What is most impressive about this radio is its relative freedom from power issues. This radio is very conservative in its power consumption whether one is using an external 3-Volt power source, a set of "AA" cells, or the supplied 2 x "AAA" cell internal-rechargeable pack.

Reading the pre-sales description of this radio one may mistakenly assume that it plays for only thirty minutes from the internal rechargeable batteries. In fact what is being claimed is that one-minute of cranking the dynamo results in 30-minutes of playback. Cranking for two minutes will result in one hour of playback. The longer you crank the longer it plays. When fully charged the internal rechargeable pack will operate the radio at a reasonable volume level all day and on into the night.

The radio has a built-in replaceable "AAA" plug-in battery pack similar to those found in wireless phones. These batteries are recharged by the dynamo. This pack is accessible and replaceable, after 300-500 recharge cycles, by removing six-screws at the back of the case.

Further two "AA" batteries are easily replaceable through an access-port at the rear of the cabinet. The radio can also be powered by an external source, solar-cell, wall-wart, or what have you, through a socket located under a splash-proof cover on the left-side of the radio.

The dynamo handle is sturdy. The left-side of the case is partially cylindrical in shape. The left-edge of the speaker grill is actually a rubber grip. The radio is well balanced and easy to hold while cranking the dynamo. The dynamo can be cranked in either direction facilitating use by either Right or Left handed people. Lefties will not be able to see the green-LED which illuminates to indicate that one has reached adequate dynamo cranking speed. A minor inconvenience.

The bottom of the case has four rubber-pads which when combined with the radio's weight cause it to grip well on flat surfaces. No tipping. The overall build quality, fit and finish, of this radio is very-good.

A splash-proof earphone port is located next to the external power-port. Both earphone channels are driven, monaurally. The radio's internal speaker is only two-inches in diameter. This is not a boom-box, but the sound that emanates from the speaker is very accurate within its effective range. Classical and Jass music sound fine. If you are a heavy rock-listener you may yearn for more oomph in your everyday listening.
The primary purpose of this radio is to provide information when the lights go out, but it makes a useful everyday radio as well, with the previously mentioned exception for rockers.

There is a small incandescent bulb that illuminates the slide-rule tuning-dial and provides enough-light externally for small-tasks such as reading your watch or a business-card. The lamp is illuminated through a small push-button on the front of the cabinet. There is another small push-button on the top of the cabinet. This button activates a chirping sound through the speaker. The sound is similar to that of a smoke detector, but not as loud. This does not seem like a very useful feature but perhaps some of you will think of a use for it?

Another switch on the top of the radio selects between the AM and FM bands. A switch on the back of the radio selects between the internal dynamo powered batteries, or the replaceable "AA" battery and external power options.

Most importantly, in addition to all of the above, is that this radio has very good sensitivity and selectivity characteristics. Analog-dial radio tuning may be a new experience for any of you that were raised on digital-dial radios. The Vernier slide-rule dial of this radio is relatively small so one has to tune slowly and deliberately to isolate stations. However, once a station is tuned-in, one is rewarded with solid drift-free reception. The audio is free of noise or distortion, has surprising fidelity, and good dynamic range, within the limited range of the small speaker.

I recommend that every household have one of these radios, and another in the trunk of the car. When disaster inevitably strikes the prudent use of this radio as a source of current information could allay further personal-suffering, or loss of life.

Eton FR300 Emergency Crank Radio Review

Average Reviews:

(More customer reviews)I got this specifically for emergencies. In the big fires we had here a couple years ago, radio was pretty much useless on the first day - several stations were off the air due to power failures and the press conferences with the police and fire chief were all on TV.Eventually, the radio stations advised people to watch their TVs.This unit gets good audio reception on three local broadcast TV stations plus a whack of AM and FM stations. Another reviewer indicated that the FM tuning isn't great. They're right - it isn't. That's the missing star in my rating.The NOAA weather stations come in well too.Once there's no more free broadcast TV signals, I guess this will be an expensive hand-cranked AM radio.

Product Description:
With a dependable hand-crank power generator that powers the unit's AM/FM/TV/Weather radio, built-in LED flashlight, cell phone charger and emergency siren, the lightweight and portable Eton FR300 is an excellent and economical choice for anyone in the market for a radio that can be relied on in emergencies or in environments where there are limited power sources.

Power When You Need It
At the heart of all of Eton's emergency radios, including the FR300, is an internal generator that recharges the internal Ni-MH battery pack and powers the radio, siren, and light. Also, by plugging your cell phone into the jack on the back of the radio, you can use the crank to power your phone. In our test, after draining our cell phone of power, we recharged it using the FR300 enough to make a few calls. The rate of cell phone recharging will vary greatly depending on the cell phone and the state of its battery, but the FR300 can provide your compatible p!hone with power in a pinch.



Important Note: Until this year, Eton provided a package of several different cell phone adapter tips with every radio. In 2007, Eton began instead including a coupon for a free adapter for whatever phone you have. So, the first thing you want to do when you get the radio is fill out the card with your cell phone's make and model and send it in to make sure you have your adapter.


According to the product manual, to achieve 40 to 60 minutes of uninterrupted power to the radio, you must turn the crank at a rate of two revolutions per second for 90 seconds. In our test, after our initial 90 seconds of rigorous cranking, the FR300 powered right up and was still going strong with radio reception after an hour. At the hour mark, we briefly turned the flashlight on, and that too was at full force, with no perceivable drain on radio reception. In fact, the FR300 was still going strong over 75 minutes after we recharged t!he battery pack. The FR300 can also be powered via an AC adapt!er which , to our dismay, is not included, or from three AA batteries, also not included. The dynamo crank tucks itself nicely into the side of the radio and offers little resistance as you turn the handle. (Don't let the cranking requirements frighten you! While it's true that a full 90 seconds of turning the crank can be tiring and may not be for everyone, we were able to recharge the radio with less than a minute of cranking and achieved over 40 minutes of continuous power.)


Design and Controls
At slightly more than a pound in weight, and with dimensions of 6.5 x 6.00 x 2.5 inches (WxHxD), the FR300 is made to be tucked neatly into its handy nylon carrying case, and stored in an emergency box, or packed neatly for a camping trip. A white LED light is set on the front of the radio, just to the side of the analog tuner. The light is designed to help you down an unlit stairwell or enclosed hallway in a pinch, but it is not directed or strong enough to help you much in a pitch-black forest or other open area. The FR300 also includes a red flash!ing LED light that can be used as a distress signal. The radio and light can be operated simultaneously, though of course at the expense of power.





The large tuning knob and other controls make the FR300 a breeze to use. View larger.

Kaito Electronics Inc. KA500BLK Voyager Solar/Dynamo Emergency Radio - Black Review

Average Reviews:

(More customer reviews)I tested the KA500 along with several other self-powered radios for a project I'm working on in rural Sub-Saharan Africa.I found that the KA500 is a very capable shortwave receiver it's just not nearly as rugged as its competitors. Here are my thoughts:

What I like about the KA500:
- Solar Panel--the KA500 is one of the only portable shortwave receivers out there with a built-in solar panel. The panel is effective enough that it will power the radio (if in direct sunlight) without batteries and produce a reasonable amount of volume through its built-in speaker.

- The 5 LED reading lamp -- This reading lamp is impressive. If the batteries are fully charged, the lamp works for VERY long periods of time. I'm also an amateur radio operator and found that the reading lamp is bright enough that it lit up my large radio table.

- Good shortwave sensitivity -- For a self-powered analog radio, I was impressed with the shortwave sensitivity. I also found the AM broadcast and FM bands adequate/average.

- Good selectivity -- When a station is tuned-in well, you don't often hear adjacent signals.

- Good frequency coverage -- I like the fact that KA500 covers the NOAA weather frequencies, FM, AM and a very large portion of the SW spectrum (from 3.2 MHZ to 22MHz, missing only a little used piece between 8 & 9 MHz)

What I didn't like:
- Quality -- Though the radio feels solid in your hand, I found through my testing that the quality of the KA500 is actually quite poor. More than once, the tuning mechanism would slip and the needle would get stuck in the middle of the dial. The worst part, though, is the poor quality of the hand-crank mechanism. The dynamo and crank arm feel cheap. Well, they are cheap.After only a month of occasional testing--and with me being very careful with the hand crank--the dynamo started showing signs of failing. The crank became less fluid to turn and would rub the side of the radio chassis. One day, while slowly cranking, the crank arm just snapped in half. No more crank power.

- No Fine Tune control -- Kaito fits the whole SW1 and SW2 spectrum on a small dial. There were a few times I wish this radio had a fine tune control like the Grundig FR200.

BOTTOM LINE:
I sent my KA500 back and did not get it replaced. It's a shame, really. I loved the radio's features and overall performance, but was very disappointed with quality.

I could only recommend this radio to someone who plans on tucking it away and using it on rare occasions or someone who wants a basic full-featured radio but never plans on using the hand-crank.I'd also keep the receipt handy for the return (and buy from an authorized dealer like Amazon or Universal Radio).

For my purposes, I will be using the Grundig/Et

(More customer reviews)Do not buy this radio.The hand crank option failed to work on the one I purchased, which would seem to defeat the purpose of owning it.In addition, it is impossible to contact the manufacturer regarding a replacement.This is the second problem I have had with products from this company, as I also purchased a flashlight that did not work.Avoid Innovage Outdoor.
