The ALPHA 86 is a self-contained, HF linear power amplifier capable of continuous operation at a power output of 1500 watts PEP, keyed CW, SSTV, RTTY, or AM, with no time limit (rated for continuous commercial service, "CCS"). Units delivered within the USA and its territories and possessions are manually tunable over the frequency range of 1.8 to 22 MHz. They may be user-modified to extend coverage to 29.7 MHz. Units delivered elsewhere cover 1.8 through 30 MHz. Performance is optimized for amateur bands. The ALPHA 86 is capable of high-speed, full break-in CW (QSK) when used with a suitably-designed transceiver. Note: the term "transceiver" includes suitable transmitter-receiver combinations, such as the Collins S-Line and Drake R4C-T4XC, etc. The ALPHA 86 is fully compatible with CW, AMTOR, or PACKET modes.
