  • Notes
  • TU-47 &48 &49 &50 &51 &52 &53 &54 are 8 vertical placed plug-in units to cover the frequency range of the BC-610 transmitter, 2.0 to 18 MHZ. Each TU provides tuning over its range for the RF-oscillator, the buffer/doubler and intermediate power amplifier; the oscillator-dial can be locked. Three sockets are provided in the transmitter to plug in 3 TU's at the same time, and a band-switch at the transmitter's front allows the operator to select one. Each TU can hold a FT-171 crystal which can be activated with a toggle-switch. The frequency range of TU-47 is 2.0-2.5 MHZ
