Deliveries started on March 22, 2013 ...

Software defined receivers have been state-of-the art for years already; now the ZS-1 from
St. Petersburg offers SDR Transceiver capabilities at “direct sampling” level.

The ZS-1 is a real software defined shortwave transceiver for the classic HF amateur
bands, including WARC bands, offering an output power of up to 15 W. For receiving purposes,
the transceiver covers all frequencies between 300 kHz to 30 MHz. High quality band pass
filters ensure clean signals. A broadband spectrum and waterfall display inform simultaneously
about activities within a given band, so no pile up will remain undetected.

The transceiver is connected to the PC via a USB2.0 connection, a built-in interface
additionally allows to operate the unit via an IP address, and also CAT-connectivity is ensured.

The delivery includes the comfortable operation software Zeus Radio, which was written
especially for the ZS-1. It offers access to all functions, including the comprehensive
settings for the digital signal processing of the microphone input and the integrated CW
keyer. Furthermore the software packages Ham Radio Deluxe, and SDRmax III
may be used in conjunction with the ZS-1.

The transmitter output power is adjustable from 0 dBm (within the entire range, for antenna
analysis or operation of a transverter) up to 15 W within the amateur radio bands.
A power monitor with additional display of voltage and current is included, too,
software protection of the final amplifier against high values
In the future the SWR will be displayed also, the essential hardware is already built-in.
