We always want to be a part of Educating young students on Amateur Radio Electronics and Science.

Here is and example of the very first International Space Station Contact ever done using UHF linked repeaters and IRLP (VoIP System) and it was done in Chapel Hill, North Carolina.

Barbara Pedersen KE4JZM's science class at Phillips Middle School in Chapel Hill reached new heights on November 9th, with a scheduled contact to the International Space Station. The contact, part of ARISS (Amateur Radio on the ISS), was originally scheduled for Tuesday, but was just postponed by NASA until November 9, at 11:28 AM.

This pass lasted just over 10 minutes, and reached an elevation of 60° over Chapel Hill at 11:33 AM, traveling from northwest to southeast.
Students from throughout the school submitted questions to ask, and a panel of teachers selected the "winning" questions. The prize for the students who wrote the questions was getting to step up to the microphone and ask the questions live during the ISS pass.
KE4JZM's classroom features a permanent amateur radio station for HF, VHF/UHF and satellite operation. The former SAREX (Shuttle Amateur Radio Experiment) program transferred to the Space Station after a permanent Amateur Radio station was installed earlier this year. For several years, the ham station aboard the MIR space station was also used to make school contacts, supplementing the SAREX program.  Pedersen applied for a shuttle or MIR contact nearly five years ago.

The KD4RAA - K4JDR Repeater Group in Raleigh learned of the ISS contact a week prior to the scheduled contact date.  Danny Musten KD4RAA consulted with Gary Pearce KN4AQ and Buddy Furr K4UNC  (two of the facilitators for airing  the contact over the W4UNC UHF repeater in Chapel Hill),  to explore the possibilities of "broadcasting" the scheduled ISS contact over the IRLP  network of worldwide linked repeaters. After shared enthusiasm for doing the  link, Danny, Ron and Jack Thorpe WA0ERX, on short notice, went to work to set up the link on local IRLP nodes 426 and 427 with connections to the East Coast IRLP Reflector 921.  General announcements were made over the IRLP node owners and users lists with invitations to link their local repeaters to Reflector 921 to hear the contact. Raleigh Node 4270 was linked via a UHF remote base to the Chapel Hill 442.150 repeater and we were able to monitor the feed on our VHF 426 node (146.775  in Raleigh). The UHF link to 427 had an approximate 30 mile trip to Chapel Hill from Raleigh. On the morning of the contact Ron Casey K4JDR reset the remote base on the Repeater Group's UHF link system allowing us to have coverage on our local network of linked UHF repeaters as well. Ron and Dan monitored the contact from the Hub at Musten Communications, while Jack closely monitored Ref 921 at Inflow.  Jim Price had a host of folks around his office desk also monitoring this historic event.

After the local students finished their contact, several participating IRLP nodes checked into Reflector 921.
Many of repeaters around the world had local school classes monitoring in on the ISS contact and after
the contact expressed their appreciation for making the IRLP link possible. You can hear several
check-ins from participating IRLP nodes around the world at the end of the IRLP audio MP3.

Jack Thorpe WA0ERX, our node administrator for Reflector 921 reported that with 38 nodes connected, the bandwidth at the Raleigh Inflow office peaked at 3.7 Meg.

IRLP link of the ISS Chapel Hill contact was made possible through the efforts of:
INFLOW Raleigh Division (our host for Reflector 921) Jack Thorpe WA0ERX, Jim Price WW4M, Ronnie J. Casey K4JDR, Gary Pearce KN4AQ, Buddy Furr K4UNC and Danny Musten KD4RAA
