(tr)uSDX 5-band | multimode TRx | 5W | QRP

Apr. 20th, 2022 – Until we solve the issues with the efficiency of the PA stage in roWaves (tr)uSDX kits, all sales for this product (kit / assembled / kit, no case) have been stopped on March 11th, 2022 and are currently on-hold. Accessories for this product can be ordered at any time, if in stock. Deliveries of the existing pre-orders received until March, 11th (ONLY NOT SENT ORDERS) are on-hold, until each customer still awaiting for the kit/assembled (tr)uSDX, confirms sending the product as it is, or requests the cancellation/complete refunding. For customers that already received the kit (and have now working (tr)uSDX products, with only the PA stage efficiency issue) and that do not want to wait for a technical solution(s), please contact us via email for refund proposals. We thank you, and many apologies for this. Our report and official communication on this matter, available HERE.

From original creators of (tr)uSDX, Guido-PE1NNZ & Manuel-DL2MAN, we are offering several options for this beautiful 5-band, pocket-size, multimode QRP SDR TRx, under license CC BY-ND 4.0 (for HW&SW) and CC-BY-SA (for enclosure). Technical support is available ONLY from DL2MAN’s webpage and forum, use these resources with confidence. Accessories available below. Very important: tap (cut threads) “Lower Wall” and “Upper Wall” before putting M3 Screws in, otherwise the case walls might crack because of the pressure of the M3 screws.
