TAPR Kitting of the DSP-10 2-Meter Software Radio

N7HPR writes "TAPR is pleased to offer the DSP-10 2-Meter Software Defined Transceiver in surface-mount kit form. The kit was design by Bob Larkin, W7PUA, and is explained in a three-part article published in QST magazine September, October and November of 1999. Bob continues to update and improve the software, which he has released as free software under the GNU license.


The official DSP-10 Project web page is at http://www.proaxis.com/~boblark/dsp10.htm


TAPR's kitting of the DSP-10 is in keeping with its tradition as a member supported Amateur Radio Research and Development organization and supporting the development of Software Defined Radios (SDR). TAPR's mission is to develop and support "Enabling Technologies" which further the role of Amateur Radio as an experimental radio service, allowing hams to once again "tinker" with their radios. Now the "tinkering" can be done purely in software.



The DSP-10 is a low-power, all-mode 2-meter transceiver using Digital Signal Processing (DSP) at the last IF and audio stages. The DSP-10 is an excellent example of a Software Defined Radio (SDR). Most all characteristics of the radio are under software DSP control: modulation, demodulation and front panel.



An example of the DSP-10's processing capabilities, on 25 February 2001 Ernie, W7LHL, and Larry, W7SZ, were successful with a PUA43 mode QSO on 1296 MHz EME (Moon bounce). They were using a QRP power level of 5-Watts and backyard TVRO dishes of 10 and 12 feet.



The potential builder is encouraged to research the DSP-10 Project at the above web page and determine if they meet the level of skill required to complete the kit. There are several successfully constructed DSP-10's in the world and elmers are available on the discussion group at dsp-10@qth.net. Subscription information is available at the DSP-10 Project Web Page or http://www.qth.net.



Kit building experience required is moderate to advanced. The kit will provide the builder with all the necessary materials to complete the transceiver. The majority of the components on the PCB are surface mount. The Hammond Enclosure will require drilling. An internal shielded box for the DSP is made from double-sided PCB material. Not included in the kit are microphone or speaker.



The kit will contain all components, PCB, and Hammond Enclosure. All that is required to complete the kit is an Analog Devices EZ-Kit Lite DSP (Analog Devices P/N ADDS-2181-EZLITE). A listing of Analog Devices Distributors is available at

To accommodate those builders who have already purchased a PCB from Mashell Electric, a kit with only the components and Hammond Enclosure will be offered. Eventually, only one kit will be offered containing components, PCB, and Hammond Enclosure.



TAPR plans for the initial kitting of the DSP-10 to produce over 100 kits. Parts are being procured and kits are estimated to be available in the July time frame. Due to the high cost of the kit, orders will be taken and payment received now to offset the expense of parts purchasing. TAPR will continue to stock the DSP-10 as long as there is interest and parts remain available.



Ordering information is available on the TAPR Web site http://www.tapr.org Potential buyers can contact the TAPR office via web, email, fax, or telephone and place their orders. Payment can be made by check, money order or credit card. Shipping costs are extra and depend on your shipping method and location.



Information of kitting progress will be posted on the DSP-10 list and the TAPR web page.
