The first question for the majority is why such pathos? Why is your craft cooler than the Chinese clones and replicas of mcHF? First, it's really cooler. This is a real constructor for a real cool radio amateur for every taste, many options without wires and electrical tape. Second, in order:- The sensitivity is 4-6 dB higher thanks to the modified two-balance mixer.- Input module of the receiving path with switchable RF amplifier (better than in mcHF) and attenuators 12 and 24 dB, as it should be for a good transceiver.- Full-fledged work in the ranges 160 and 6m.- With careful tuning, the carrier and image channel suppression is no worse than 50 dB on each band. There is an option that significantly improves carrier rejection at low power levels (less than 5W). That is, you can safely connect an external PA without fear of hearing an offensive humiliating LID on the air.- Consumption in receive mode is no more than 220 mA, weight is no more than 650 g, the ability to work on CB bands, adjustable rise/fall timing of CW signal and other tasty buns in the firmware and bootloader. Output power not less than 10 W on all HF bands, in the range of 6 m not less than 2.5 W.
Enough for a start. See the documentation for details - Docs & Files .The project archive is constantly growing, so I also posted it in parts - Docs and Files .

The project is completely open and meets all the conditions of open licenses for hardware and software. All the information necessary for assembling and configuring the transceiver, including the topology of the boards, is available in the project archive. Ask for advice, I will be happy to help everyone.
What can I offer besides documentation and firmware? Kits of bare boards, "lazy" DIY kits (see the project documentation for specifications), ready-made debugged and tuned transceivers (included power cable and push-to-talk microphone).
Prices are highly dependent on the current purchase prices for boards and radio components. When they decrease, will naturally decrease too. I am constantly looking for new wholesale suppliers, not blinded by greed, but very picky about the quality of components. With a shortage of specific positions, compromises have to be made, but quality and reliability are always a priority.
The situation is complicated if the boards are in stock, everything else is only on order. The transceiver may appear in free sale if the customer is not in touch or has refused. If there are no working capital, an advance payment will be required for the purchase of components. Almost everything is done by hand, but I plan to eventually order stencils for applying solder paste and a budget automatic SMD installer. This will greatly speed up and simplify the process.
Delivery is paid separately at the fact, so when ordering, immediately indicate where the parcel should be sent and preferred delivery service, I will find out the cost of delivery and let you know. Here are indicative prices and are not a public offer. Write to e-mail, the address is listed below. Later I plan to add an online store engine on the site and open stores on ebay and aliexpress sites. 73!
