The ATS-3B--the worlds smallest and lightest multi-band CW HF rig. This latest version of the popular AT Sprint CW transceiver now covers 80 through 15 meters, using plug in filter modules (not shown). A single digit LED display has been added for frequency and battery voltage readout. (in addition to Morse annunciation). Over current detection has been added to protect the PA. The transmitter produces 2.5 watts out with just a 9 volt supply--on all bands. Supply voltage can range from as little as 6 volts to a maximum of 12. An improved PA keying circuit ensures consistent rise and fall times of the CW output signal, regardless of supply voltage.   Available early September, 2007 for $190.00
