In both the U.S. and Canada, amateur radio operators serve an important role in providing emergency radio communications during war, disaster, terrorist attack, or whatever other emergency. So amateur radio operators take an extremely dim view of unlicensed operators using frequencies allocated to amateur (or sometimes commercial) radio. Many will even hunt ...

It looks like radar reflectors will not hurt but they aren't great either. The bigger and higher they are the better, which is easier to do on a sailboat than a sea kayak. According to one study, a homemade reflector worn on the paddler's hat provided the best signal reflections. The distance they can be seen regardless of a radar reflector is limited, ...

Allow me to turn your question on its head a bit. Making yourself more visible to large vessels is a good idea, not being where they need you to be visible is a great idea. Stay away from channels, shipping lanes, and docking areas. You are small and in a craft that can turn and stop in mere inches- a laden freighter on the other hand, might measure those ...

The solution was to remove the battery from the battery compartment at the bottom of the radio. This turned off the radio. After turning the radio on, it's responsive again. Mind that for this to work, the radio mustn't be connected to another power source with a USB cable. Meaning you should unplug the radio before removing the battery so it actually turns ...

Excluding the legality question, as to be honest, that's likely to depend on who detects you, and how much it interferes with licensed traffic, the safety angle has a couple of aspects: It doesn't look like you will clash with emergency services, however there is a risk that you will clash with local amateur radio operators who may be handling emergency ...

There's a lot of variation between radios. There's even a great deal of variation for a given set. I own a pair of radios advertised as "35-mile range." I don't believe that's false, but it's probably under ideal conditions - a clear day with two people on mountaintops 35 miles apart, with an unobstructed view, for example. I did a test with mine where I ...

Personal radio devices in Europe use a different frequency (446 Mhz). According to a quick google search the frequency range of GMRS/FRS (462-467 Mhz) is used by fire brigades in UK, police in Russia and licensed radio amateurs in Germany... blocking frequencies of police or fire brigades will certainly cause you trouble here.

I am an amateur radio operator (Extra Class) active in Skywarn. Yes, PMR radios transmit in the amateur radio spectrum in Canada and the U.S. Yes, it is not legal. In the wilderness, far away from civilization, and with handheld radios that emit a few hundred milliwatts, you will absolutely, positively not interfere with anyone. If by the smallest of ...

What you are looking for is a walkie-talkie / two-way radio / private mobile radio with voice control. Normally, to communicate with a walkie-talkie, you need to press a transmit button. Some models, however, have voice-control: they will automatically start transmitting based on voice input. My friend and I used the Midland G7 XTR, that includes this ...

The range mostly depends on the power of your radio. 500 mW is OK, 5 W is much better. You should study what frequency ranges and what maximum power are allowed in your country for public, and go for the max power. Ranges may include FRS, GMRS, LPD, PMR. E.g. in Russia FRS is prohibited and LPD is allowed, while e.g. in Kazakhstan it's vice versa (so we are ...

Family Radio Service, the most commonly available walkie talkies, operates on frequencies around 460 MHz. The power is limited to only 500 mW, and as such is very limited. Wikipedia reports that the average range is roughly a mile, which is quite reasonable, given the power levels and poor antennas. Of course, this may vary. If you are wanting more reliable ...

next to a small river so I could step out into the clear to get at least some view of the sky That's really the bare minimum for good signal. This will have much more impact than how you hold it. If you can go to a clear high ground not too far away, it will help. If not, there isn't much to do but try until you get good signal.

Alternately you may be able to change the frequency your current device uses. In the US you will usually find a "CB Shop" near large truck stops, they should have the skills & parts required to modify the units. Practically, it maybe more efficient to just get new devices.

As I cannot find the exact specs of the type of antenna they use I can only speculate. My guess is that the antenna is either unidirectional or placed along the length axis of the device. If the antenna is not (completely) unidirectional it should work best when the device is laying on it's back. This way the radio waves will definitely radiate upwards out ...
