Tristar 747 Modifications

PLEASE NOTE! Despite what most people seem to think these radios are not the same as a Ham International Multimode II even though they look very similar. The Multimode II has a single sided circuit board (PTBM059COX) with a separate crystal and VCO board (PT0S006AOX), and the Tristar 747 has a double sided circuit board (PTBM121D4X) with a separate crystal board located on the side of the radio (PTOS011AOX or PTOS012AOX).
