"Texas Star CW Transmitters
(Models DX 250, DX 250HDV, DX 350 and DX 350HDV)
These transmitters are designed for mobile or base CW operation. Powered by
the 12 volt vehicle battery or 12 volt regulated power supply, the maximum
power output is less than 5 watts RMS. Frequency of operation is within the
10 meter band, determined by installation of a crystal into the oscillator
board. The transmitters contain a transmit/receive relay and an output
connector for the receiver to share the antenna and permit break-in
operation."
Descriptions of the other "amplifiers" are similar. There's a sample
schematic for one of the rigs, the 350. This QRP 10 meter CW transmitter
curiously has a pair of 2SC2879 finals in push-pull that develop 5 watts.
The transmitters are shipped in an inoperable function -- users must
install a suitable 10 meter crysal on the internal oscillator board.
Conversion instructions to increase the power output and band coverage of
these _TRANSMITTERS_ are readily available on the web, but NOT on the Texas
Star site.
Texas Star does not sell amplifiers in the US. They sell QRP 10 meter CW
transmitters. Some customers choose to modify these transmitters to suit
their own needs.
If you don't live in the US, you may be able to purchase one of these other
models from Texas Star:
