DXpedition to Navassa Island 2015 K1N

This island was off the air for a generation. #1 most wanted country.

Mike showed us a great video of the two-week expedition.

There is a DVD available from the K1N website.

How can you get started? Gain experience on an easy DXpedition first, such as the Virgin Islands, during a holiday. You need lots of time off work, DX experience, CW experience, disposable income (around $10,000+), and you need to get on a team somehow.

December MicroHAMS meeting will be dinner only with some door prizes for participants!

New SDR Group – John Petrich, W7FU

John is making a special interest group (SIG) about Software Defined Radio(SDR).

Please stay tuned for another message to MicroHAMS real soon that talks about this.

We’ll meet three times a year.

Let’s compile a list of names of MicroHAMS who would be interested.

He’s open to ideas about the location to meet.

The first group meeting will be after the holidays.

Low end SDRs (in terms of price) have been of the most interest, generally.

MicroHAMs Dinner-Only Meeting on August 18th

Our August MicroHAMs Dinner-Only meeting will be held at the Canyons Restaurant in Redmond. We have half the back room reserved thanks to Scott Slack.

Location URL: http://canyonsrestaurant.com/locations/

We will be meeting Tuesday, August 18th at 6:00 pm. Please note that the Canyons does not (strangely) bill individually for the meal (quote “Its a hassle for the server”). We will need to pay Scott Slack back after the meal, so bring cash or a check so Scott can get paid back after the dinner. (Sorry about that everyone!) During the meal, we will shoot for an open discussion on MicroHAMs in general, taking any thoughts or suggestions for enhancing the club experience.

July 2015 Meeting Topic: EXOR

What is missing in digital ham radio?  I describe how our digital
systems should be different than conventional systems.  I propose a
list of the parts missing.  I propose general ways to improve our
digital systems interoperability.  I ask the question what have I
missed that we need in our systems.

We will learn about EXOR (extremely opportunistic routing protocol)

Marshall Denny,  AI4CM,  has a background in physics and computer
science. He is President of the Bainbridge Club, ACS area coordinator,
BI;  In ham radio for 23 years, interests in  HF Digital modes & HF
antenna design, messaging protocols.  Software Developer / High
