Revised Shipping Estimate

We are pleased to report that we now have firm delivery dates for the long-lead parts and expect to have them all at our assembly house by the end of next month. Assembly is envisaged to take about six weeks, which pushes delivery out to the third week in August. We expect to start shipping before then, however, since we plan to supply units in batches, as they come off the assembly line and complete production testing. Read the full update.

Shipping Delay

Unfortunately, the situation with COVID-19 has resulted in a further delay to manufacturing. We're not able to provide a revised date just yet, but we're hoping to have confirmation by the end of next week (Friday 10th April) and plan to provide another update in due course. Read the full update.

New Shipping Estimate & Acrylic Case

Due to lead times on some parts, we have had to push our estimated ship date back to 31st March 2020. This includes both crowdfunding orders and pre-orders. If you backed our campaign or placed a pre-order, keep reading to see a photograph of the acrylic case we'll be sending you along with your LimeRFE! Read the full update.

Performance of the Final Production Board

Two days left! In this update, we will look at the performance of our final LimeRFE 1v0 design by combining measurements from the prototype 0v3 board with simulated results for the newly added amateur radio bands (50/70 MHz, 220 MHz, and 920 MHz) and the updated 1280 MHz band.

WSPR Test

We sent a 0v3 prototype board to radio amateur and GNSS engineer Daniel Estévez (EA4GPZ), so he could put it through its paces and provide feedback as we fine tune the design. Even with a damaged prototype, his Weak Signal Propagation Reporter (WSPR) transmissions from Madrid were being picked up as far away as the Canary Islands, Netherlands and Northern England.
