Flex 1500 SDR - Amateur Radio Suppliers since 1979 in association with Waters & Stanton - UK Nationwide Delivery and Technical Support

The latest addition to the "FLEX" family of software defined radios is the FLEX-1500. A low-cost, low-wattage SDR that is positioned to allow ham radio operators the ability to experience the incredible capabilities and just plain fun of operating a software defined radios without breaking the budget. The FLEX-1500 is the quintessential entry-level SDR from the same company that brought you the innovative FLEX-5000™ and FLEX-3000™ software defined radios. The FLEX-1500 comes packed with features that make it ideally positioned to be the ultimate low cost, high performance IF deck for VHF-microwave transverter operation. With a low price and the continuous improvements and upgrades provided by PowerSDR™, the FLEX-1500 is by far the best value for any entry-level amateur radio available today produced by any manufacturer. Low Cost Transceiver with Software Defined Radio Features and Performance. This is a common theme for FlexRadio Systems' software defined radios - a focus on performance and exceptional value. And the FLEX-1500 continues that tradition for a transceiver in this price class.

No External Sound Card is Required. Just like all of the software defined radios in the FLEX family, the FLEX-1500 does not require an external sound card for the A/D and D/A conversion, so there are no cumbersome audio cables to mess with. Just a single USB connection to your computer is all you need to operate the FLEX-1500.

Small Form Factor Facilitates Portable Operation. Like its "bigger brother" the FLEX-3000, the FLEX-1500 is a space optimized software defined radio measuring in at approximately 101 x 152 x 50mm. in an all aluminum case. Designed for most types of operating conditions, the FLEX-1500 is small in size, light weight and has low power consumption.
High Gain Preamp for Increased Sensitivity. Sensitivity, not blocking dynamic range is important for a weak signal operation. The FLEX-1500 can be configured for weak signal operation using low-noise, high gain pre-amplifiers or attenuate it for increased blocking dynamic range.

Fully Compatible with FlexRadio PowerSDR and the New "Next Generation" SDR Software Architecture. The FLEX-1500, like all of the software defined radios in the FLEX family, is designed specifically for the current standard in SDR software for amateur radio use; PowerSDR. And it will be 100% compatible with any future SDR software from FlexRadio Systems. This ensures that the FLEX-1500 will just keep getting better with convenient software updates from the Internet.

5 Watt PA for 160 to 6m QRP Operation. The FLEX-1500 is a low power software defined radio with an RF output of 1 milliwatt (0 dBm) PEP on 160-6m using the transverter antenna connector(s). Five (5) watts nominal RF output is available using the transceiver antenna connector.
The Perfect IF Deck for VHF-Microwave Transverters. The FLEX-1500, with its ultra low power output and 10 MHz input for an external high stability clock source, when combined with PowerSDR it becomes an ideal IF deck for driving VHF+ transverters.
FlexWire™ Version 2 Port for Control of external devices. In order to interface with external devices like relay control for transverters, key out for transmit and sequencing for transverters, preamps and power amplifiers, the FLEX-1500 will have the external interface capability needed to be a full featured IF deck for VHF-microwave transverters.
