Click on the picture above for Dot Code practice and test. In addition to sounders, we at the OVCWA use small 25 milliwatt Broadcast Band Modulated CW transmitters which have 140 ohm relays keying the transmitter. This signal is received by small pocket radios with the earphone in the collar allowing those without "click" training to receive both Dot Code and Morse as a Ham radio would. The OVCWA Standardized Telegraph System (STS) is HERE The OVCWA STS interface is HERE.

Meet your Hosts!

Dave Bock, Ted Wagner, and Dave Harbin are amateur radio operators (ham radio).  We all know International Morse.   Dave Harbin is, by far, the best American Morse operator.
