98 MONITORING TIMES February 2000

Yaesu VR-500 Portable Scanner

he Yaesu VR-500 is a multi-

mode, wide coverage receiver

small enough to fit in one’s palm.

tenna has a deep null centered near 159 MHz

which extends a few MHz on either side. A

local 159.15 MHz repeater barely produces

an S-meter reading. The S-meter springs to

almost full scale when using the antenna

from a Uniden/Sportcat SC200.

Its array of modes, wide frequency cov-

erage, and 1000 memory channels with

alpha labels, competes with the Alinco

DJ-X10T (Nov. 1998 MT), ICOM IC-

R10 (Mar. 1997 MT), and AOR AR-

8200 (Oct. 1998 MT). Its diminutive

size is in the same class as the ICOM IC-

R2 (Apr. 1999 MT) and AOR AR16

(Aug. 1999 MT). All of these models

can exchange frequency information

with a computer when used with op-

tional software and cable.

The VR-500 is advertised in the USA

as covering 0.1 - 1299.9995 MHz, ex-

cluding cellular phone bands. Our VR-

500 (s/n 9G031495) has three addi-

tional gaps above 600 MHz (see Measure-

ments section). This is a compromise which

permits the VR-500 to comply with new FCC

regulations mandating a minimum 38 dB

rejection of cellular phone signals.

Basic Features

The Japanese-made VR-500 detects NFM,

wide FM, AM, USB, LSB, and CW signals.

There are 13 step sizes ranging from 50 Hz to

100 kHz. Like most of the competition, the

VR-500 sports an S-meter. It employs rotary

volume and squelch knobs and a numeric

keypad. The plastic belt clip fastens to the

rear with a single screw which loosened a few

times.

The VR-500’s adjustable contrast display

and keypad can be backlit for easy night

viewing. Lighting is triggered by pressing

any key. You can configure the backlighting

to latch on or time out after 5 seconds.

Both the VR-500 and IC-R2 are powered

by two AA batteries. The IC-R2 is sold with

800 mAH NiCd cells and a 7 hour charger,

but none are furnished with the VR-500. Our

VR-500 consumes only 73 mA while scan-

ning, a 33% savings over our IC-R2. On the

other hand, our VR-500 consumes more cur-

rent while turned off. The VR-500 is fitted

with an external power jack so the radio can

be powered by a 9 - 16 VDC source.

Memory and Such

The VR-500 has one VFO and 1000

memory channels in 10 banks. You can pro-

gram an 8 character label for each channel,

and both the label and frequency are dis-

played while scanning or stopped. The VR-

500 label scheme works better than the IC-

R10 in which the label is only visible for a

few seconds in manual mode.

The VR-500’s RF attenuator is global to

all channels and the VFO. The IC-R10’s

attenuator may be programmed on a per-

channel basis.

Searching and Scanning

The VR-500 supports both VFO

and limit searches with 10 pairs of

frequency limits. You can designate a

step size or have the VR-500 choose an

“Auto” step size based on the frequency.

Up to 100 frequencies may be skipped during

a search and they are stored in separate memo-

ries which are retained until you clear them.

Smart Search resembles the auto store

feature in other models but is quite limited.

Program upper, lower, and start frequencies

and the VR-500 will search for signals, stor-

ing active frequencies into temporary memory

locations. We find the Smart Search to be

dumb for these reasons: The scanner makes

only one sweep through the designated spec-

trum. Smart Sweep memories can be read

only after the sweep, become inaccessible

when exiting the Smart Sweep mode, and are

erased the next time you enter Smart Sweep

mode.

Unlike the IC-R2, the VR-500 can scan

various combinations of memory banks. The

global rescan delay can be set from 1 to 12

seconds. Each channel has a “preferential”

flag instead of lockout. You can option the

VR-500 to scan all channels in selected banks

or only channels with the preferential bit set.

It sounds complicated but works well in ac-

tual use. The VR-500 supports a mode scan,

but we can’t think of a good use for it.

The VR-500 has a Dual Watch mode which

is simply a way to scan pairs of channels.

There are 10 dedicated pairs of Dual Watch

memories which you can program with dif-

ferent frequencies and modes.

VHF/UHF Performance

The supplied antenna uses a BNC connec-

tor and appears to be base loaded. Our an-
