The DSP-10 is an amateur-radio, software-defined 2-meter transceiver that can be built at home. It operates on SSB, FM and CW modes. Features are tailored to operation with weak signals on VHF, UHF and Microwave frequencies. The transceiver is low power, about 20 milliwatts, but there is provision for adding an 8-Watt amplifier.
Bob Larkin, W7PUA, the creator of the DSP-10 is pleased that TAPR is kitting the DSP-10. 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 is pleased to offer the DSP-10 2-Meter Software Defined Transceiver in surface-mount kit form.
The DSP-10 was featured in a three-part article in QST September, October and November 1999.
The kit contains all components, PCB, and Hammond Enclosure. All that is required to complete the kit is a DSP module such as the
- KK7P DSPx Module and KDSP10 Interface Adapter available from TAPR
- Analog Devices ADSP-2181 Evaluation Board (ADDS-2181-EZLITE). A listing of Analog Devices Distributors is available online.
The price for the DSP-10 2-Meter Transceiver is:
$ 299 US for members of TAPR
$ 329 US for non-members+ shipping/handling if applicable.
Shipping and Handling
Shipping and Handling within the US will be by USPS Priority Mail.
International shipping costs are calculated as closely as possible. If the actual cost exceeds the estimate by more than $5.00, TAPR will contact you to get approval for the additional funds. TAPR uses insured Priority Mail International, unless the purchaser requires something else.

TAPR kits can be complex depending on the kitting experience of each builder. We don't think you will have trouble with the DSP-10 kit, but it does require some knowledge and experience to successfully go from a kit to a finished, usable unit, depending on the mode of operations.
Questions about the assembly and operation of the DSP-10 will be handled on the DSP-10 list.

- All kits have been sold. Some parts are no longer
available, so there will be no more kits. There may be a few
un-built kits in closets somewhere. Advertise on some of the ham
web sites if you want to buy or sell.

- TAPR still has a small stock of these kits
January 29, 2002
We started shipping kits from waiting list.
September 10, 2001
We are nearing the completion of the DSP-10 kitting. All that remains now is the final kitting of the surface mount parts. It was discovered yet again that one of the parts was not the correct part shipped. Yet another annoying delay getting the correct part. But all of the larger parts are stuffed into envelopes, the enclosures are in, PCBs are in, just about everything you need to complete your DSP-10 is in.
We hope that we have thought of everything you need. Included in the kit is no-clean solder and a no-clean flux pen (following the great idea by Dan N8FGV). We've included hookup wire and Teflon coax (RG-316) for the PCB. All the screws, nuts, and even brass nuts for putting together the shielded box for the DSP. The PCB material has already been cut to size.
We plan to place the assembly manual on the DSP-10 and TAPR web pages. It is not finished, but I hope to find time to work on it now that most of the kitting is done. This way you can download the latest version. I plan to take a number of digital pictures during the construction process as I build a second DSP-10.
As we mentioned before, the one thing you will need to purchase separately is the Analog Devices EZ-KIT Lite. We see that Newark and Future are carrying them. Other items not included are the microphone, power supply, external connectors and cables. You may need to supply some internal hookup wire. But all hardware and connectors internal to the DSP-10 enclosure are included.
We anticipate shipping of the kits to start the beginning of October. I know we've set goals and missed them before. For that we are sorry. Everyone working on this project are volunteers and the DSP-10 kitting has been one of the most ambitious undertaken by TAPR. We think you will enjoy your kit this Fall and Winter. Perhaps then you will bring them and show them off during Dayton and the September 2002 Digital Communications Conference.
Kitting progresses, even if it is ever so slowly. With over 140 unique parts, some with multiple quantities, the DSP-10 makes for a large kitting project. There is a large amount of time required for preparation, such as DIPs in conductive foam, measuring magnet wire and solder, cutting SMT electrolytic caps on tape. But kitting is progressing.
We are discovering a few nuisance problems that slow down kitting progress. One such item we recently discovering is the SMT 22K ohm resistors are not what they seem. The distributor sent us the wrong thing in its place. So we have to rectify that situation so we can get back to kitting.
Already, 3 of the 5 envelopes of parts are at the TAPR office, including PCBs. The final 2 envelopes will be completed next week. We are awaiting the Hammond enclosures from Mouser. The SMT parts will be finished when we get new 22K ohm resistors.
The TAPR Office move has been completed, though later than we expected. Thanks to the break down of a rental truck! So now the process of organizing the office and our new office manager Laura Koster getting settled in her new role.
I have been receiving emails from several folks asking if kits are still available. Yes they are. Over 100 DSP-10 kits are being kitted in this first run. Over 80 orders have been taken so far. We will continue to keep the DSP-10 in stock as long as there is interest. So if you have not ordered your kit you can still do so now.
Estimated kit delivery is now toward the end of August. Sorry for the long kitting time and delay. We appreciate your patience. But I think you will be very pleased with the kit when you receive it. Especially since the summer is coming to a close (at least in the Northern Hemisphere :-) and kids are returning to school. The weather will start cooling down driving most indoors to build their new DSP-10's.
Just a short update. All the major parts for the DSP-10 have been received and are in the process of kitting. Several parts have already been placed in envelopes and mailed to the new TAPR office. PCBs are on order and scheduled to ship the end of July. Some minor parts are on order such as screws. We still anticipate delivery of the kits in the first half of August.
For everyone that has pre-ordered a DSP-10 kit from TAPR, the TAPR Office move will temporarily close the office until the move is complete. Kitting on the DSP-10 continues. Those involved in the kitting of the DSP-10 are coordinating sending their completed portion of the kit to the new office. There they will be packed and shipped from the new office. The goal is to mail the kits out to everyone the beginning of August.
Thanks for everyone's patience. Kitting is going smoothly and all the major parts are in.
As always, any questions please email me or the DSP-10 list.
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
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 email@example.com. Subscription information is available at the DSP-10 Project Web Page or http://www.qth.net.
Kit building experience required is moderate to advance. 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.
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.

- Components plus Hammond Enclosure (less PCB)
- Components plus PCB and Hammond Enclosure
A short status report on the kitting progress of the DSP-10 at TAPR.
We are polishing the final details of the DSP-10 kit. The kit will be offered in two versions:
The kit less PCB will accommodate those who have already purchased the PCB. This was based on the email requests received. After a period of time only the complete kit will be offered.
We are still investigating the purchase of the Analog Devices EZ-Kit Lite DSP for those hams unable to locate them in their country. Purchase and sale of the EZ-Kit Lite will be provided as a service and the cost will be passed onto the buyer. There are no volume discounts available. Thus the cost will not reflect a discount. For those hams in the U.S., Canada, and Europe, it is suggested that you purchase the ADDS-2181-EZLITE, new part number, or old p/n ADDS-21XX-EZLITE from an ADI distributor. See http://www.analog.com/product/distributors.html or you can buy direct from ADI. More information on the EZ-Kit Lite will be posted when it is finalized.
Prices will be announced in the next couple of weeks and orders will taken then. Availability of the kit will be around the July time frame. As mentioned, TAPR plans to keep the DSP-10 kit in stock as long as there is interest in the kit and parts are available. TAPR will continue to improve the kit as the community of DSP-10's grow.
TAPR will be at Dayton this year and we will be talking about Software Defined Radios during the TAPR Digital Packet Forum on Friday May 18th at 10:15 AM - 11:00 AM. I'll be demonstrating the DSP-10 at the forum and it will be on display at the TAPR Booth 542-543.
TAPR is planning on kitting the DSP-10 an All-Mode 2-Meter Software Defined Transceiver. The DSP-10 was featured in a three part article in QST September, October and November 1999. The official DSP-10 Project web page is at http://www.proaxis.com/~boblark/dsp10.htm. Bob Larkin, W7PUA, the creator of the DSP-10 is pleased that TAPR is taking on the kitting of the DSP-10. 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).
It is anticipated that it'll take approximately 2-3 months to gather all the parts and assemble the kits. As many are aware, some of the parts are hard to find and/or have a long lead time. If you know of a source for these harder to find parts, please let me know.
The kit will be as complete as possible. The goal is to provide a kit of parts that will enable the builder to complete the DSP-10. However, the kit builder should be prepared to complete the DSP-10 from locally procured parts such as wire and hardware. The plan will be to provide a kit similar to what Dan Schultz, N8FGV, did in his first two kittings, all the components and circuit board. Dan also did a nice touch by providing 63/37 solder, no-clean solder flux pen, and no-clean flux desoldering braid.
What may not be provided is the Hammond enclosure or EZ-Kit Lite DSP. If there is enough interest for an enclosure, it can be included. There is no bulk purchase price for the EZ-Kit Lite DSP and thus does not provide a monetary benefit to the kit builder. It is therefore suggested that you purchase the EZ-Kit Lite DSP from a distributor near you.
Kit building experience required is moderate to advanced. Support for the kit will be from the DSP-10 list or its successors. Several people have successfully built the DSP-10 and they are on the DSP-10 list. There is a wealth of information on the DSP-10 Project web page mentioned above.
TAPR is not equipped to do case-by-case custom orders. TAPR is a member supported volunteer R&D organization and custom orders would overwhelm the limited resources we already have. However, we are always looking for good helpers. Let me know if you would like to assist in this or any other TAPR projects.
Price for the kit has not been set. Once a price is set, orders can be made and payment will be requested to offset the cost of the parts ordering.
