ARLA/CLUSTER: RS-HFIQ is a high performance Software Defined Radio (SDR) 5W Transceiver for CW, SSB, AM, FM and digital modes

[João Costa > CT1FBF]

Kickstarter: HobbyPCB 5 watt SDR starting at $239

The *RS-HFIQ* is a high performance Software Defined Radio (SDR) 5W
Transceiver for CW, SSB, AM, FM and digital modes.

132 backers so far, $28,422 pledged of $15,000 goal and there are 24 days
to go

Not just another SDR - The RS-HFIQ offers real RF performance for serious
communications. Covering the 80-10M Amatuer Radio bands with excellent RX
performance and 5 watts of TX power, using open-source SDR software for CW,
SSB, AM, FM and digital modes, the RS-HFIQ sets a new standard for
shortwave SDR communications.

*Specifications*

Frequency Range – 3-30 MHz (performance guaranteed on
80/60/40/30/20/17/15/12/10M ham bands)

Sensitivity – MDS <-128 dBm on 80M dropping to <-135 on 10M (depending on
processing bandwidth and sound card performance)

Noise Figure - <15 dB on 80M decreasing to <10 dB on 10M

TX Power 5W typical, 4W minimum
LO Feed-thru < -50 dBc @ 5W output
Spurious and Harmonics <-50 dBc typical <43 guaranteed
DC Power 13.8VDC, 2A max, plus USB power for the Arduino Nano

*Who should buy one?*

Amateur Radio Operators – Both newly licensed Hams looking for their first
shortwave radio and experienced operators looking to explore the world of
software defined radios

Experimenters – Hams and non-Hams who like to work with hardware and
software will find the open-source aspects of the RS-HFIQ invite innovative
shortwave experimentation

Radio Clubs – what better way to insure that newly licensed hams become
active than including a transceiver with a licensing class?

Shortwave Listeners – From BBC to Radio Tanzania to oceanic air traffic
control, there’s plenty to hear on shortwave. The RS-HFIQ is a great place
to start and ready to TX if you decide to get an amateur radio license.

*Shortwave Communications*

The RS-HFIQ radio board turns your PC and sound card in to a high
performance shortwave transceiver for operation on Ham Radio and MARS
frequencies. Unlike most radio channels in use today that are limited to
line-of-sight ranges, shortwave signals have the unique ability to reflect
from the ionosphere high above the earth and be heard thousands of
kilometers away. With some perseverance and operating skill it is possible
to work all 50 states and more the 300 different countries with the RS-HFIQ
radio.

*High Performance RF Design*

As you might imagine, operating requirements for a radio that send signals
nearly to space and back are more stringent than requirements for radios
that only have to communicate with the nearest cell tower.
The technology and techniques are not new; on December 12, 1901, Guglielmo
Marconi succeeded in sending the first radio transmission across the
Atlantic Ocean. During the intervening 115 years, many innovators have left
their mark on the shortwave communications art. Today, with properly
designed equipment, like the RS-HFIQ, it is possible to achieve long range
communications as a matter of routine.
