Microwave radio require free line of sight between point A and B. Any obstruction in the first Fresnel zone (imaginary ellipsoid zone between point A and B) will degrade the availability. Furthermore, rain attenuation is affect the transmission in frequency above 10GHz.

∙ 10y agoHam radio presents disadvantages to no one else but the licensed Amateur operator himself.
#1). As with any other hobby that monopolizes the attention and presents
steadily escalating challenges, a weak character can allow Amateur Radio to
become an obsession, leading to all the obvious concommittant social consequences.
#2). As with any other hobby that can involve expensive toys and appurtenances,
a weak character can wallow in the fantasy that more and bigger are better, and
can ultimately allow Amateur Radio to become a priority of such unwarranted
primacy that he bankrupts himself and his loved ones, all in the pursuit of, say,
DXCC via QRP-EME-microwave, or some such idol.

∙ 12y agoThe only disadvantage of ham radio is the one it shares with aviation, boating,
philately, knitting, numismatics, WikiAnswers, Bowling, billiards, and any other
hobby or avocation with the capacity to become addictive ... the risk that the
devotee will develop a pursuit, attachment, and habit so strong that it will
make inordinate demands on his resources of time, attention, dedication,
finances, and sociability.

What does phone mean in amateur radio?
Radiotelephone- that is voice talking ( called Phone for short) . The term , with the advent of cellular phones, which are in a very real sense radiophones- has engendered some confusion. Before their advent (Phone) in Amateur Radio use meant voice conversation- called Radiotelephone. The other major transmission mode was of course CW- Continuous Wave- that is, Code transmission- or radiotelegraphy. As of now, there are, of course , different types of licenses for Phone, and Code transmission. Prior to l992 there was an arbitrary Code test for ALL prospective amateurs. This ( Model T) requirement has been modified if one is using only Phone. Still there are the CW zealots.
What are the advantages and disadvantages of a DAB radio?
Advantages of DAB Radio over FM/AM radio's: 1) they automatically tune into all of the available radio stations and so do not need retuning 2) they can display extra information using PAD, such as the song title, artist name and general information about the radio station 3) there is a greater choise of satations 4) There is less interference, and does not have the crackle that you sometimes getwith an FM/AM radio 5) With the newer and better made DAB radio's, you can pause and rewind the radio station Disadvantages of DAB Rdio's 1) there is not world wide coverage, so many areas have poor or no DAB radio signal 2) They are much more expensive - you can get a normal radio for less than £10, but it is very dificult to buy a DAB radio for less than £25 3) Most cars still use FM/AM radio's, so if FM/AM radio was shut down and only DAB radio was used then about 2/3 of people would not be able to liusten to music in there cars.
Why when the radio is on it makes a screeching noise?
Possibilities include: tuner chip degrading; audio amplifier failing; other discrete component failure; AM is more sensitive to local radio interference than FM; microwave oven nearby; another radio, tv or computer nearby; surveillance bugs in area; wireless alarm systems; feedback from piggy-back radio using household power lines (which serve as the antenna system); proximity to high voltage power lines or radio/tv towers; or a local amateur radio transmitter in area.

How did Percy Spencer invent the microwave?
When he was testing radio transmission using microwaves, he observed that one of his chickens was cooked to perfection. He realised that this was a very energy efficient way of heating things so he thought that he would put it to good use.

What types of wave are microwaves?
Microwaves are the electromagnetic waves in a large part of the broad range usually called "radio waves".They're the radiation with wavelengths between about 1 mm and 10 cm, corresponding to frequenciesbetween 3 - 300 GHz.Interestingly ... the term "microwave" is officially not used for radio waves with wavelengthslonger than 10 cm (frequency below 3 GHz). If you hold to that official definition, then the microwaveoven ... operating at 2.45 GHz ... is using radio waves, but officially not using 'microwave' energy.
