AMRAD Meeting this Thursday

[Karl W4KRL]

*Free dinner or free developers kit?*

At Tacos some of you have seen the Arduino developers kit that you will
receive at the door the night of AMRAD's Anniversary dinner. This is really
a powerful and useful platform for experimentation. If you bought these
components off the shelf they would cost more than $20. So free dinner or
free kit? No need to chose. You get both with your reservation!

The latest version of the AMRAD Anniversary announcement is attached. Note
that we are now able to take reservations by check or online credit card.
Additionally we will take cash for your reservations at the meeting this
Thursday and at Tacos every Saturday.

*73 Karl W4KRL*

   - *May 14, 2015, 7:30pm – Pete McNeil, KF4HCW, “Digital Modulation
   Description Language”*
      - While considering remote operations on HF there are two problems:
      1. Most digital modes done these days require a lot of bandwidth because
      the signals are being transmitted and received as digitized audio (or
      worse), and 2. Network delays introduce timing problems inherent
in CW work
      that are not normally apparent in half-duplex digital and audio work.
      - Pete will share his thoughts on developing a method to send digital
      timing information rather than analog audio to the transmitter and use
      direct synthesis to perform high fidelity modulation. It may be
possible to
      use the descriptive language to code every currently known modulation
      scheme and then later use the same mechanism for schemes that
have not yet
      been invented.
