FlexRadio Systems Product Status Update
Tuesday, August 31, 2010
Dear FlexRadio customers:
I am writing to provide a status update for our new products. Here is the latest:
The FLEX-1500™ has been shipping in volume since May with great
success. We sold out of stock again earlier this month and are waiting for another large production run starting delivery next week.
As previously reported, the FLEX-1500 currently uses WASAPI on Windows 7 or ASIO4ALL on XP and Vista as audio drivers to provide streaming data to and from PowerSDR. Prior to shipment of the FLEX-1500, FlexRadio wrote a custom USB streaming driver using a driver development toolkit (DDK) from a well respected company. Unfortunately, we discovered a bug in their DDK that prevented long term stability of the driver. We shipped a radio to the company for testing over two months ago. It took six weeks to get the radio through customs in their country and they have just this weekend confirmed the source of their problem. They are now analyzing the different options for fixing the problem in their code. Once the fix is completed, we will be able to eliminate the generic Windows sound drivers thus simplifying installation and reducing latency.
PowerSDR™ 2.0 is in the final release stages. Recently, we implemented a new Agile framework to add structure to our software development process. This has resulted in significantly improved speed of development and management visibility. We are working now toward an official release candidate of PowerSDR 2.0 after we eliminate the few remaining class 1 and 2 bugs. We expect this to take two or three more beta release cycles. With over 2,000 downloads of PowerSDR Beta 2.0.8, we are seeing very stable operation in the vast majority of installations.
We are pleased to announce that the FLEX-VU5K™ has been released to production at our contract manufacturer. During the field beta test process we determined the need to redesign the heat sink to provide better cooling of the PA modules. The new thermal design has been successfully
verified for extended key down periods. With production now released, our plan is to begin upgrading customer radios within five weeks. We will contact customers in the FLEX-VU5K upgrade queue for scheduling.
PowerSDR 2.0 will provide SSB, CW, AM and digital mode support for the FLEX-VU5K. VFO-A and VFO-B will be supported in 2.0 for dual band monitoring or cross band transceiver operation. Satellite operation can be supported on 2.0 using CAT commands from various satellite tracking programs. Full FM support with programmable repeater split operation, CTCSS tone access and satellite locked tuning will come in PowerSDR 2.1.
We thank you for your patience as we complete these important new products.

Gerald, K5SDR
The FlexRadio FLEX-1500™ QRP Software Defined Radio
 The pre-order backlog of FLEX-1500 has been completely processed. Since the demand for the FLEX-1500 has been and continues to be very strong, please check with Sales before ordering for an accurate delivery date as stock levels fluctuate on a daily basis. For more information and pictures of the FLEX-1500, visit the FLEX-1500 Product Features web page.
New V/U Module Adds VHF and UHF Capabilities to the FLEX-5000
The FLEX-5000 V/U module (FLEX-VU5K) is a fully integrated all-mode, all-band (144-148/430-450 MHz) full-duplex VHF/UHF module that adds both 2m and 70 cm capabilities to the already outstanding FLEX-5000 family of software defined radios. The FLEX-VU5K module's oscillators are locked to the 500 MHz master oscillator in the FLEX-5000, which in turn is locked to the internal 0.5ppm reference or it may be connected to an external 10 MHz reference for even greater frequency stability.
The high power FLEX-VU5K module (shown installed in a FLEX-5000A) transforms the FLEX-5000 into the ultimate satellite or terrestrial weak signal transceiver. A pair of class "AB" power amplifiers provide enough RF output on both bands to drive most external high power UHF and VHF amplifiers. If you would like to see more detailed specifications on the FLEX-VU5K Module, please see the FLEX-5000 Upgrades web page.
FlexRadio PowerSDR 1.18.6 Released
We are pleased to announce a maintenance release of FlexRadio PowerSDR (v1.18.6) which is recommended for all user's of FlexRadio Systems' software defined radios. There is support for revised hardware in this maintenance release. Please refer to the FlexRadio PowerSDR v1.18.6 - Release Notes for more information.
Turn your FLEX-5000 Software Defined Radio into a Triplex Transceiver with the Addition of the Second Independent Synchronous Receiver (RX2)
The RX2 is an all mode, all band completely independent synchronous receiver that has the same ultra-high performance specifications as the main receiver. When utilized with the upgraded HRFIO-34 board, the FLEX-5000 fully software defined radio becomes a true SO2R solution in a single radio enclosure. Features such as full synchronous diversity reception which provides beam steering capabilities and noise elimination and a host of other capabilities are possible with the RX2, such as actually monitoring your transmitted signal in real time just to name one. Technical details about the RX2 can be found on the
FLEX-5000 Software Defined Radio Upgrades web page.
