The JRC JST-100.
The compact HF tranceiver employs an 8 bit microprocessor to control all the complicated fuctions sush as band and mode selections.and memory control, and memory channel acces.The 11 channel memory can easily store and recall not only VFO frequncies but also working frequncy bands and modes.The JST-100 is fully equipped with attractive and powerfull capabilities such as tree PLL circuits phase-lock with a highly stable 10 MHz standard crystal oscillator: two digital VFO's permitting independent selection of bands and modes; and memory finder capabillity with the working VFO being held.
