Just back from Orlando Hamcation. Nice to meet many of our existing customers and chat with some new ones.

The UDRX made it thru initial bring-up and I drove them to Oregon, while Portland was being slammed with snow. Jeremy has completed the updated Drivers and PLD code and shipped the first unit to Dennis for IQ audio and RF path analysis.

No significant problems were found at this stage.

I’ll be  working on the PA and RX/TX switch while Dennis fine tunes the IQ/RF.

I’ve also been working with CMs and it looks like we’ll be be able to meet our production cost goals at this point. There is still ambiguity on the Heat Sink Extrusion and enclosure cost.

I’ll post approximately monthly as we continue to make progress.

After dealing with component shortages and Holiday schedule, the UDRX pilot boards arrived this afternoon from our assembly house in Renton WA.

The boards now go into the lab for initial bring-up, then they will be split into 3 task groups:

• SW Driver additions and updates
• IQ audio and RF path
• PA and RX/TX switch

There are a substantial number of relatively minor changes to the design, in addition to the major change in form factor to accommodate the switch to the R-Pi 3.

I will provide an update on our progress by Hamcation in Orlando next month, where the pilot units will be on display. There is still significant work ahead, before we can determine if the pilot run can move to production.

Thanks for your patience and support,
Bryan K7UDR
