MicroHAMS club meeting – January 17th, 2017

MicroHAMS Club Meeting
Tuesday, January 17th at 6:00 PM
Location: Building 35/4561

Portable Radio Kits by Scott N7SS
Come see Scott’s Blue Box to get some ideas about how to make your own portable radio station that is highly functional even when the going gets rough. When you make your own custom rig, it also has to be smart, fun, and cool. N7SS shows us one way of how that’s done.

Ham Help
If you don’t know everything about amateur radio yet, that’s OK. As a club, we have a broad spectrum of interests and experiences. Please feel free to ask questions at this part of the meeting.

146.58 MHz FM simplex will be monitored for anyone who needs help finding the site or for access to the building. (Monitoring is done with handhelds, so range is limited.) If you’re running late and are locked out, please call us on the radio or Tim’s phone at (425) 898-3815. We’ll send someone to let you in.

SECURITY NOTE: Anyone who does not have their own Microsoft badge for unescorted access to Microsoft buildings MUST be escorted into Building 35 and conference room 4561 by a badged MicroHAMS member. Do NOT under any circumstances attempt to “tag” onto or “tailgate” Microsoft employees entering the building. Please congregate about five minutes before the meeting outside the lobby entrance on the south side of the building.

MicroHAMS meetings are open to club members, those interested in joining the club (see club membership policy at http://www.microhams.com), and guests of club members. Others may also attend a club meeting by sending email to the club at least seven days prior to the meeting. Space for guests is limited.

MHDC 2016 write up on ARRL website

The MicroHAMS Digital Conference got a nice write up on the ARRL website. While Ward-N0AX is quoted in the post, I believe he was actually the author as well. Thanks Ward to the kind words and coming out to talk!

NOTE: I will be sending off the raw video feeds to the production editor next week. Hopefully we will start seeing the individual edited talks from Budd-WB7FHC soon…

The video from the live stream is now available on YouTube.(Link)  At some point in the future, each session will be edited down (with more camera angles, etc.) and links will be made available on the MicroHAMS web site.

In the mean time, the stream is available and the actual presentations can be downloaded from the MHDC 2016 page.  The agenda with the original presentation times and YouTube stream start times is below.

MicroHAMS Digital Conference – Update 5.1

Due to the space limitations and because we like trying new things, we are going to attempt to live stream the MHDC this weekend. Our original goal was to just stream Bryan-K7UDR’s talk on the NWDigitalRadio UDRx product, since there is so much interest on it. But in the process of preparing for that, we realized we might be able to stream most/all of the conference.

I have step up the stream on YouTube. Our goals is to stream Bryan’s talk that starts at 13:30 PDT. We will probably make our first attempt at streaming a talk in the morning as a trial run. I can’t promise we will be successful at any of it, since we have never done this before. Our history tells me we may take all morning debugging things before getting something to work. But maybe Murphy will stay home and it will just work.

When the stream goes live, I will also be in the chat room to take questions. Wish us luck!

MicroHAMS Digital Conference – Update 4

We are now three days out from the conference and everything behind the scenes is dropping into place. As predicted, the conference sold out several weeks ago. If you were not able to reserve a spot, we hope you can attend next year. (There will be NO onsite registration this year due to space limitations)

We wanted to make sure people had a few more details about the conference, including the exact address of Building 37 on the Microsoft campus and start/end times. All of this information is available on the conference flyer, available here: MHDC 2016 Flyer. The agenda for the day is still being finalized, but I will get it posted here when it is available. (Hopefully in the next 24 hours)  The line up of speakers hasn’t changed, we are just adjusting the order to accommodate peoples schedules.

One additional note, we are planning on recording all the talks again this year and like last year, Budd Churchward, WB7FHC has agreed to edit and release them on his YouTube channel. We also plan on live streaming Bryan Hoyer-K7UDR’s talk on the UDRx. Check back here for the details in the next couple days.

MicroHAMS Digital Conference – Update 3

Just a quick reminder that pre-registration is required for this years conference and there is a hard limit of 90 people. As of this morning (3/3/16) there are only 11 slots left. If you are planning on attending and have not registered yet, I’d suggest you do it now.

MicroHAMS Digital Conference – Update 2

The final speaker for the conference has been posted, Phil Horkin-AF7GY will be speaking about using line of sight (LOS) for MIMO applications. Here is a quicks summary of his talk:

As a brief explanation of the topic, Line of Sight (LOS) MIMO is rather new technology that uses multiple antennas on both the transmitter and receiver, much like conventional (Non-Line of Sight MIMO), but operates in the absence of multipath. Because of this distinction, there are constraints on how this technology may be used, requiring careful placement of both transmitting and receiving antennas, but where it is applicable, may be used to double or triple the link throughput without a linear increase in aggregate transmit power.

LOS MIMO has its greatest applicability to high data rate systems, either for fixed wireless, or with one node moving. While this will have somewhat limited applicability to amateur radio, our thought has been that this is an example of a digital system employing SDR and radio communications technology that many amateurs may find interesting.
