We plan to have a "show and tell" of several implementations of digital modes.  Among those planned are using D-Star and a portable PSK station using the NUE-PSK modem. Attendees are encouraged to bring their own pet project(s) to show and tell during the demonstration period(s)..

The purpose of continuing this series of technical presentations is to encourage others to get involved in the technical aspects of the hobby and to share the knowledge of what others are doing.  You do not have to be an innovator to participate, just someone interested in what is happening in the realm of electronics technology.   As you can see we will have a varied program of topics presented by a group of skilled and knowledgeable individuals.  Come and learn.  The price is right!



There is no charge for attending the symposium.  A box lunch will be available on site.   Updates to the program will be posted here on the website, so please check in from time to time.  For further information please contact  Jay Slough, K4ZLE, k4zle <at> embarqmail <dot> com.

Bring your portable or semi-portable digital station!
We'd like to have as many types of stations, and as many demos as possible
We'll have a secured room, open during the registration and lunch period, for demos.
If you have an interest in CW, RTTY, Packet Radio, AMTOR, D-Star, etc., please plan to join us.

Interest in digital came with RTTY in the late 60s, followed by Packet Radio in the 80s-90s supporting the development of the TNC-1, 2 and serving on the TAPR board for 6 years.

Following the development of SDR, Mel began with the 3-board SDR set from now Flex Radio, then to the Flex 5000 and currently enjoying the latest developments from the HPSDR project.

Professionally, Mel worked 32 years for a large telecom company and retired as a Senior Member of Technical Staff in 2000.  Mel continues active in the electronics and telecom fields as owner of small Midwest consulting firm since 2001.

Past calls include WA8MMN, WA9ZSN and finally N9CX when he lived in the Indianapolis (IN) area. Bill is a long time member of the ARRL and enjoys CW and other digital modes on the HF bands.  He is affiliated with the CRES amateur radio club in the Columbus, Ohio area and has served as the club's president for the last 3 years.  A favorite pastime is designing and building microcontroller based projects.

Bill graduated from Purdue University where he studied electrical engineering technology and computer science. He retired from Lucent Technologies in 2001 and now does independent contracting on a part time basis.

Larry Phipps, N8LP

Larry Phipps, N8LP, has been licensed since 1965, first as WN8PSD, later as WA8PSD and finally as N8LP, when he upgraded to Amateur Extra.

He left school in 1971 to work full-time at WJBK as a broadcast engineer. He then moved to NET Television Inc (a subsidiary of WNET-TV, New York), where he was instrumental in launching one of the first computer controlled videotape-editing facilities in the country. He and XYL Janet founded TelePost Inc, a high end television post-production facility in 1986.

Gerd Schrick WB8IFM

Gerd, fascinated with the “Action at a Distance” since high school was first licensed in 1951. He did a lot of home brewing and experimenting in those days. However, what interests him to this day, is the sensation of talking to a person at the other end of the world with his own equipment. He got into amateur satellites, as soon as they provided this capability. The first contact on AO-10 was with Italy in 1984. He has since been hooked on the Phase 3 satellites. In the past two years he spent over 3 months helping with the building of P3d. He is “retired “ from work as an Electronics Engineer and presently divides his time being AMSAT Area Coordinator for SW-Ohio, President of QCWA Chapter 9, Treasurer and Newsletter Editor of the Midwest VHF/UHF Society among other “diversions”.

Background:

The South West Ohio Digital Symposium has been held each year since 1987, for the purpose of promoting digital modes of communications via Amateur Radio. The primary, but not exclusive, thrust is packet radio and networking, but we try to present other modes including CW, RTTY, coherent CW, et. cetera. (semaphore and smoke signals were discussed during one session.)

Sponsoring organizations are The Center for Chemistry Education of Miami University, the DIAL Radio Club, and the Ohio Packet Council.

The symposium is non profit, we make no money - we try to break even.

Comments and suggestions are welcome.
