Circuit Boards and Kits can be ordered via PayPal. Prices include free shipping.
I will usually ship within one business day via USPS first class and provide tracking info. Foreign orders may require additional shipping charges so contact me via e-mail. Special pricing is available for group orders. Contact me via e-mail. I have a supply of SRA-1 mixers and 100 Mhz oscillators on hand. All circuit boards are high quality, FR4 material with plated through holes, solder mask on both sides and silkscreen image on top layer.
Pricing includes for the kit, and assembled boards, all parts that mount on the board and the board itself. The dongle, cabinet, switches, etc. are not included and must be obtained separately. Use a dongle with an 820T or 820T2 tuner. Prices on the internet are typically less than $10. The 820T2 dongle is the newer version.
Includes all parts that mount on board. Does not include dongle, switches, enclosure, etc.
Does not include dongle.
This transmitter electronic radio kit was featured in the August 2017 issue of QST magazine.
Three printed circuit boards are used to provide the basic functions of control, sideband generation and RF amplification and filtering.
Control is based on a TI microprocessor and readily available DDS modules. The second board generates high quality sideband RF at 9 Mhz and mixes with the DDS output to generate RF at the output frequency.
This design is controlled via USB ports tied to a computer running free downloaded software such as SDR#, HDSDR or similar programs.
This design is recommended for experienced builders because of the complexity and number of parts. Additional output filters must also be constructed to aid compliance with FCC requirements. These boards form the basis for any SSB transmitter project
Output power is in the 1-2 watt range.
Includes Boards A, B, C
