Is It Legal?

The FCC doesn’t require equip-

ment authorization for any “Amateur

Radio” transmitter to be operated

under Part 97, except those that

incorporate scanning receivers,

which require a grant of certification.

If an Amateur Radio transmitter also

includes frequencies allocated to

other services, and if the device is

intended to operate in those other

services as well as the Amateur

Service, then the transmitter must

be certified for all non-Part 97 radio

services for which it is intended to

operate. The FCC uses the term “in-

tended to operate” as being equiva-

lent to “capable of operation.”

Wouxun is able to legally market

a device that operates in the bands

specified and that has a scanning

receiver, because it has a certifica-

tion grant (for Part 90 operation)

which satisfies the certification

requirement with respect to the

scanning receiver. It can be oper-

ated by Part 97 licensees and by

Part 90 licensees in their respective

frequency bands.

Wouxun US chooses to limit the

frequency range of the amateur

version of the device to ham bands

only. Restricting the frequency

range of the device to ham bands

only is okay as a Class I permissive

change (without recertification) as

long as the means for restricting the

frequency range in the amateur ver-

sion of the device is not done with

hardware changes and without any

denigration of the characteristics of

the device as reported to the FCC.

Wouxun US presumably wants to

make sure that Part 97 licensees

do not operate the device on Part

90 channels, and vice-versa. It is

good practice for them to market

the ham band only version to hams,

and to market the Part 90 band only

version to Part 90 licensees. Good

fences make good neighbors.

ful functions. While the KG-UV2D is not

nearly as sophisticated, it does have a few

useful added features. The LED flashlight,

for example, is very effective. While effec-

tive, the flashlight is not always functional.

With the squelch open, you cannot turn

the flashlight on. Consequently, if the

flashlight is already on, you must have a

closed squelch to shut it off. Strange, but

considering the flashlight button is also the

momentary SQUELCH OPEN button, I’m

not surprised.

Both radios include an FM broadcast

tuner. Called “FM Digital” in the manual, the

tuner is analog only. Frequency selection is

accomplished by turning the encoding knob

or by pressing either the UP or DOWN button.

Audio is clear but some of the strongest sta-

tions overload the receiver, causing crackles

in the sound. Reorienting the antenna reduces

this unwanted effect. It appears that in China,

the FM broadcast band is 76 to 108 MHz. I

was reminded of this regularly since it reverts

to 78 MHz each time the radio is turned on.

While it’s cumbersome to crank the knob to

reach our FM broadcast band starting at 88

MHz, I’m still pleased that this inexpensive

transceiver has this feature.

Other features include a stopwatch, an

SOS function, a VOX and the ability to switch

from high to low power and back while trans-

mitting by pressing the TDR button.

It is interesting to have a handheld trans-

ceiver that can speak Chinese. I’ve learned

how to count from zero through nine and

words such as enter and function. Most

of the time, I use the English mode and I

have to admit, I have grown fond of the

young lady with the Chinese accent inside

my radio.
