This web page's purpose is to provide information for Cyclone Amateur Radio Club members about the use of Wavecomm Jr. video transmitters and receivers for Amateur Television (ATV) purposes.  At the club picnic this spring, some of us talked about the possibility of putting up an ATV repeater with a 70cm output which may easily be received by a cable ready TV set to cable 57 - 60 or with a 420-440 MHz down converter to a standard channel 3 television.
 Since Radio Shack currently has the Wavecomm Jr. units on closeout sale at $99.97 for a transmitter and receiver pair, it was thought that this may be a great way for club members to uplink to a repeater (in the  2.4 GHz  ham band) fairly inexpensively.   I was asked to provide the information I had found, in various articles, as a web page so that interested members may view it online.  The information provided here shows how they may be modified for ATV use by licensed Technician class or higher hams.  As is, these devices are intended for part 15, unlicensed operation.  Two of the four channels are inside the ham band (1 & 4).  The following modifications may only be performed by licensed Technician class or higher hams.  Once the unit has been modified, they may only be used on channels 1 & 4 which are in the ham band, and you must identify with your call sign (on the voice channel is ok or hold up a card with your callsign for video or use a computer, etc) every ten minuits and at the end of the communication.  The content of your transmissions must also conform to FCC rules and you must abide by all the FCC rules CFR 47 part 97 as you would with any other ham radio.  The information here is provided for your education only.  No warranty is made or implied.  It is suggested that if you purchase these units,  you should use them as is for a while as part 15 unlicensed low power devices and don't perform any modifications yet.  If you are interested in modifiying them for Amateur Service it would probably be best to wait until fall and we could do this together as a club project.  If you are uncomfortable with performing the modifications yourself,  I'm sure one of the experienced project builders will be glad to help out.  Read the following information and I would appreciate hearing/seeing your comments, thoughts, ideas, etc.  Have a great summer and see you next fall.  If you are going to be around this summer and wish to do some experimenting with ATV please email me.  I would appreciate the help and some people to "bounce" ideas off of.  wk8l@qsl.net
