capability. These features were described

in the May 2010 review of the FT-1900R.

The Owner’s Manual

I own radios from most of the manufac-

turers and have reviewed a few others, so I

have read through many different manuals.

The FT-2900R has some typical and not so

typical capabilities, and I found its manual to

be very well written and illustrated. It does a

great job of explaining how the features could

be used, and how to activate and deactivate

and set options for them.

The FT-2900R is a fine heavy duty

2 meter radio with lots of power and some very

nice features. I particularly like the memory

bank, password protection and weather alert

features and would use them routinely. Some

of the features, EPCS and ARTS for example,

would be useful in specialized applications.

signed to as many banks as you need. With

200 channels this feature could come in

handy, especially if you are on the road and

want to group your channels by areas that you

travel. You can use this feature to manually

select channels within the bank or to scan

just the selected bank channels. Banks can

be selectively linked for scanning. This is a

pretty flexible radio.

Automatic Range Transponder

System (ARTS)

The ARTS feature uses DCS (digital

coded squelch) signaling to alert parties

with this capability that they are within

simplex communication range of each other.

When activated, a DCS code is transmit-

ted for 1 second every 25 seconds (or op-

tionally, every 15 seconds), or when the

PTT is pushed. Other radios with this

feature activated and within range can sound

an audible beep (if enabled) and display

IN RNG

on the LCD.

If out of range,

OUT RNG

will be dis-

played and polling signals will continue

until the ARTS feature is deactivated. Three

beeps will sound if you go out of range for

more than one minute and

OUT RNG

will be

displayed. After the radios are back in range,

normal beeps return and

IN RNG

is again

displayed. You can even set this radio up to

send your call sign in CW every 10 minutes

to assure compliance with identification

requirements. While the ARTS feature is

active, other functions are locked to prevent

inadvertent changes and loss of contact.

Weather Band/Weather Alert

The weather alert scan monitors for

NOAA’s 1050 Hz tone alert — this can be

optioned on or off. After turning this fea-

ture on, the weather broadcast channels are

checked for activity every five seconds. I can

set the FT-2900R to scan a memory bank to

monitor those frequencies, while also having

the weather broadcast bank scanned every

five seconds. All scanning can be observed

on the LCD, including the excursions to the

weather memory bank. I observed that even

though there may be activity on a weather

channel — indicated by a full scale S-meter

reading — without the alert tone, scanning

does not stop.

The FT-2900R also includes password

protection, busy channel lock-out, a CW

training feature and WiRES (Wide-Coverage

Small software defined radio (SDR) re-

ceivers are developing into an Amateur Radio

industry category. The QS1R “Quicksilver”

radio (Revision D); from Phillip Covington,

N8VB, of Software Radio Laboratory, is

one of the latest and most powerful. QST

has previously reviewed the Microtelecom

Perseus, the RFSpace SDR-IQ, and the more

specialized Telepost LP-PAN Panadapter.

If you combine most of these SDR radios

with a personal computer and the right soft-

ware, you have a complete general coverage

communications receiver with “panoramic”

spectrum display.

The QS1R supports a wide range of ap-

plications, from amateur and SWL listening,

to interference diagnosis and laboratory

measurements. It features wide instanta-

have middling computer or SDR experience,

there should be no trouble. If you are SDR
