October 4, 2018 Club Meeting
Thursday, October 4, 2018 at 7:00 PM Medford Police Department Community Room, 219 S. Ivy St., Medford, OR
Program: Arduino Essentials, Tom McDermott, N5EG
This program will go over the basics of the low-cost Arduino family of boards, the GUI development environment, and some Amateur Radio applications of Arduino. There will be several demonstrations.
Remember we change meeting locations starting with the October meeting. John Laybourne has secured a new meeting location for RVARC. The first meeting in the new facility will be the October 4th meeting. The new facility can hold about 150 people, has tables and chairs, a ceiling mounted projector, and a coffee pot ! It’s between Holly St. and Ivy St. along the northwest side of 10th Street. There is on-street parking as well as a parking garage nearby. The on-street parking is plentiful, time restrictions expire at 6:00 PM.

August 25, 2018 Club Meeting
Saturday, August 25, 2018, 9:00 AM—1:00 PM Kathrein / Scala, 555 Airport Rd., Medford, OR
Program: Annual Swap Meet (no business meeting)
Mike Bach WB6FFC has negotiated with Kathrein and with Cascade Christian to use a large room in the SCALA building for the RVARC swapmeet. 9:00 AM - 1:00 PM Saturday August 25. Bring tables and chairs! as there are none there presently.

June 7, 2018 Club Meeting
Thursday, June 7, 2018 at 7:00 PM New Red Cross Building, 1050A Crater Lake Ave, Medford
Program:
- How-To: Portable Operating, Allan Taylor, K7GT
- Solar Power Basics, John Armstrong, KF7UMK
This How-To program will show portable operations. Allan has a lot of experience in mountain-topping, river rafting, and other adventures where he has brought along Amateur Radio. Allan will discuss antennas, radios, power, packing, etc.
Solar power is used more and more for portable and Field Day operation, in addition to everyday tasks such as maintaining battery charge on infrequently-used vehicles, remote repeater stations, and many others. The program will cover the basics of solar power, charging batteries, and discuss some available products. John will bring along some units for show and tell.
NOTICE of Vote(s) at June Meeting: The Rogue Valley Amateur Radio Club (RVARC) will conduct a vote or votes at the June 2018 meeting to authorize nonrecurring expense(s) for Field Day activities in an amount that will exceed $150.
Announced in the June 2018 issue of The Repeater.
May 3, 2018 Club Meeting
Thursday, May 3, 2018 at 7:00 PM New Red Cross Building, 1050A Crater Lake Ave, Medford
Program:
- How-To: Broadband an 80 meter Dipole, Tom McDermott, N5EG
- Operating CW, Allan Taylor, K7GT
This How-To program will show several different methods to achieve an acceptable SWR using a dipole across the entire 75 / 80 m band without requiring an antenna tuner.
FT8 CW operation used to the be the main route to ham radio HF operation. CW enjoys a significant performance advantage compared to SSB, and permits contacts with simpler antennas, simpler equipment, and lower power levels. Contesting with CW is usually less stressful than phone due to the narrow bandwidth of CW and narrower receiver filters making the band seem much less crowded.
Allan Taylor, K7GT is the club president and a mostly-CW operator. He is an accomplished CW contester.

April 5, 2018 Club Meeting
Thursday, April 5, 2018 at 7:00 PM New Red Cross Building, 1050 Crater Lake Ave, Medford
Program: FT8 and WSJT-X, John Laybourne, W8WOM
RVARC is moving our meeting location to the new Red Cross facility. 1050 Crater Lake Ave. (east side), between Spring St. and E. McAndrews Rd. in Medford. About 6 blocks from our previous location.
FT8 is a new digital mode that has become very popular very quickly. It is much faster than the older JT65 mode, operating on a 15 second cycle rather than a 1 minute cycle. It retains much of the flavor of JT65 (brief pre-canned exchanges and synchronous transmit / receive cycles). WSJT-X is the free program that implements both the DSP software and a nice windows interface. WSJT-X also implements quite other modes which are optimized for different applications, such as meteor scatter and very weak signals.
John Laybourne, W8WOM. John is an active contester and DXer in the Rogue Valley, and is also currently active on new digital modes.

March 1, 2018 Club Meeting
Thursday, March 1, 2018 at 7:00 PM Red Cross Building, 60 Hawthorne St., Medford, OR (across from Hawthorne Park)
Program: History of Radar
NOTE: This program was originally scheduled for the February meeting, but due to time constraints was not able to be presented. We have tentatively re-scheduled it for March. If it is not given in March then we will substitute a contingent program on either: Transmitter non-linearity, distortion, and spectral widening, or else a presentation on The use of ferrites to make common-mode feedline chokes. Either of these would perhaps use presentation material written by Jim Brown, K9YC.
Announced in the March 2018 issue of The Repeater.
February 1, 2018 Club Meeting
Thursday, February 1, 2018 at 7:00 PM Red Cross Building, 60 Hawthorne St., Medford, OR (across from Hawthorne Park)
Program: History of Radar, Mike Bach
History of Radar, beginning from World War 2. Mike has access to the MIT Rad Lab journals dating from the time of the invention and industrialization of Radar, an incredible resource. Much of the technology was heavily classified during WW2, and declassified in later years.
Mike Bach currently is an engineer at Scala/Kathrein systems working on antennas. Mike has a wide collection of interesting RF hardware, from HF to Microwave, including high power RF.

January 4, 2018 Club Meeting
Thursday, January 4, 2018 at 7:00 PM Red Cross Building, 60 Hawthorne St., Medford, OR (across from Hawthorne Park)
Program: High Speed Multi Media MESH Networks for Ham Use, John Armstrong, KF7UMK
High Speed Multi Media (HSMM) networking involves the use of the 2.4 GHz amateur band to provide not only point-to-point high speed data links, but also the ability to mesh multiple radios into a network that is resistant against failures. It achieves this by automatically building network routes that can bypass failed radios or RF path outages. John will talk about inexpensive radios and antennas, along with free software that you can use to build your own network node, and to join the existing network in the Rogue Valley.
John Armstrong, KF7UMK is the club secretary for 201, and also a member and founder of the Rogue Hack Lab. He is involved in computer and networking related projects.

December 7, 2017 Club Meeting
Thursday, December 7, 2017 at 6:30 PM Red Cross Building, 60 Hawthorne St., Medford, OR (across from Hawthorne Park)
Program: Pot-Luck Dinner, followed by Remote Station Operation, Darrell Barker, N7CZX
The club’s December meeting will be a potluck dinner followed by a presentation on remote station operation. It will be held at the Red Cross meeting room (our normal meeting location), but start 30 minutes earlier than normal.
We will have a pot-luck dinner starting at 6:30 PM. Suggested items to bring are organized by last name (to reduce overlap on items)
- A through F—bring desert, fruit, or beverage
- G through M—bring appetizer or finger food
- N through Z—bring hot dish, vegetables, or bread
Darrell Barker, N7CZX will give the presentation. He has setup a remotely-operated station at his QTH, and will give a demonstration (assuming we can work out Internet access at the meeting location). Darrell is a member of both the RVARC and the Cascade Amateur Radio Enthusiasts (CARE). He assists with a weekly 2M net on the CARE repeater 147.100

Program: Amateur Radio in Cuba and Samoa, Dick Lemke, AD7AF
“Briefing: Amateur Radio in Cuba and Samoa Trip Prep.”? We were in Cuba in May and I spent half a day with CO2KL, Roberto Ibarra in Havana who is Secretary for the Cuban DX Club. Getting a Samoan license ahead of time is an adventure.
Dick Lemke, AD7AF like to travel, and is primarily a CW operator. He has operated an amateur radio station from a number of locations around the world.
