The KL703 is a new 500W linear Amplifer for operation between 25 and 30 MHz, (developed for the 10m amateur radio band). It may be used for all narrow band modulation types, (SSB,CW,AM,FM and data modes). It is particularly suitable for mobile operation as it requires a 13.8Vdc supply voltage. The KL703 requires about 30W for maximum output power. Harmonic output is better than -55dBc. The KL703 also features an RX pre-amplifier that may be used to increases readability of weak signals.
MLA100 is a compact 100W amplifier, with MOSFET Mitsubishi RD1100HHF1, for HF and 6mt bands from 1.8MHz to 54MHz. The amplifier features an extremely fast RX and TX switching with PIN diodes which makes it suitable for use in QSK. The driving power must be between 1 and 5W. With the PTT the device will work best, without working in VOX mode. The output filter is chosen automatically by the amplifier, but can be preselected manually by the user. On the front panel, in addition to the band in use, output power and VSWR are graphically indicated. The apparatus also has a series of automatic protections such as: over-temperature, over-pilot, excessive VSWR, overcurrent etc …
