20 Meter Moxon Vertical

The Vertical Moxon had everything I was looking for, a low TOA (Takoff Angle), wide horizon coverage, and good impedance loading. All of this was in a small enough package to fit in my relatively small back yard.

UDRC-II and the Process of Continuous Development

NWDigitalRadio - Thu, 2016-09-08 09:01

The great thing about Software is that you can improve it continuously. Here at NW Digital Radio, we view Hardware the same way. Each time we build out a PCB Fabrication run, it’s only engineering time and new solder-paste stencil charge to make any improvements. So we re-evaluate each product, looking for ways to make it better or appeal to a broader market.

Now that we’ve shipped hundreds of units, we’ve updated the UDRC based on feedback from the field.

UDRC-II Changes:
  • PTT and SQL are now independent and buffered on both ports making it a true 2 port controller
  • LEDs have been added to both PTTs and the 5V converter (only lights if wired to 12V)
  • The 12V to 5V converter has an RFI Filter and Transient Protection for Mobile Applications
  • The Audio Inputs and Outputs are now 100 ohms to improve cable matching
  • The EEPROM version allows the driver to auto-configure for the UDRC or UDRC-II

The UDRC-II starts shipping once we have all the documentation updated. All existing backorders will ship UDRC-II. The original UDRC will be obsoleted.

Limited Time Offer for all UDRC Owners!

If you’ve already purchased a UDRC, place an order for a UDRC-II by the end of September and receive a $20 Rebate. Just write UDRC Rebate in the comment field. Your email address must be in our Customer Database to qualify.
