UDRC II – Notice of Possible Programming Error

We have discovered that some UDRC IIs have shipped with a EEPROM programmed to identify it as an original UDRC.

Please review the wiki post at https://nw-digital-radio.groups.io/g/udrc/wiki/UDRC-II-EEPROM-Flashing for details on identifying and correcting this error.

Hamvention 2017 – Dayton

We will be at booth 1105 (Bldg. 1 – next to Bridgecom) on Friday and Saturday this year.

We will not be at the Hamvention on Sunday.
We will have a limited number of ThumbDV and UDRC-II units for purchase, and maybe have a little something new to show you (not the the UDRX-440).

DMR Licensing

We get frequent inquiries about using the UDRCTM for DMR. The problem is, DMR requires a license from Motorola, the cost of which is prohibitive for the Amateur Radio market.

We all know of products that seem to indicate that it’s not really a problem, until it is …

Pi Cases are back in Stock!

The new supplier has shipped cases so we’ll fill all of our backorders this week.

The price has increased to $15 for new orders.

Thanks for your patience.

Pi Cases – Delivery Update

We received the first article from the new supplier and the design needs tweaking so that the tabs will assemble correctly. We have a new sample in process and I’l keep you apprised.

UDRX – Status Report

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.

The UDRC-II Enables D-STAR on Many Repeaters

In case you missed the updates on the UDRC Wiki, there are now examples of adding D-STAR using the UDRC-II on many different repeaters:

Universal Digital Radio Controller

Yaesu DR-1X (currently available directly from Yaesu on a special promotion)

Kenwood TKR-750/850

Bridgecom Repeaters (including the 220 band)

Homebrew Systems

Use the message board to share your repeater and hotspot implementations using the UDRC or UDRC-II

If you can get at the discriminator and true FM modulator of a repeater, the UDRC-II gives you a way to add D-STAR.
