(tr)uSDX 5-band Multimode QRP TRx – KIT

From original creators of (tr)uSDX: Guido-PE1NNZ & Manuel-DL2MAN, we are pleased to announce we will offer the kit and assembled version of this beautiful 5-band, pocket-size, multimode QRP SDR TRx, under Creative Commons Attribution License CC BY-ND 4.0 (for HW&SW) and CC-BY-SA (for enclosure). Technical support for the kit will be available from DL2MAN’s webpage and forum. Use forum and instructions available there, with confidence. Accessories for it will be available, very soon. Please keep in mind that you pre-order this product. You will pay for it first, by pre-ordering, then we pack the kit and then we send it to you and to other customers (waiting time detailed below, depends on the batch/lot & option). We will ship in batches (50-100 KITs/batch).

➡️ What you will receive? (depending on options available):

(tr)uSDX – kit, no case: SMD pre-assembled PCBs plus all parts needed to finish and assemble the transceiver, but you need to 3D print the case (this option will be available later this year, estimated in March-Apr. 2022).
