ICOM shows transceiver with 70 MHz
Published on 26 August 2012 by Bo OZ2M
At the Tokyo 2012 Ham Fair ICOM had a new transceiver with 70 MHz on display the ICOM IC-7100. The text does not say anything about 70 MHz or much other details. However, searching the Internet some more detailshave been found:
  • Slanted front separated controller with large touch screen dot matrix LCD (controller cannot be attached to body front)
  • Speaker is self contained inside the controller
  • Full mode (SSB, CW, AM, FM, RTTY decode) and D-STAR DV
  • HF (100 W), 50 MHz (100 W), 70 MHz (50 W), 144 MHz (50 W) and 430 MHz (35 W). Note: Power may be different according to version. The 70 MHz band is available for some versions only
  • Lower current consumption/cooler operation (compared with the IC-7000)
  • SWR meter function also works for VHF and UHF bands
  • Remote power on/off
  • IF DSP for filtering/interference removal/noise reduction
  • SD memory card slot, voice recording
  • USB Audio In/Out, remote control
  • +/- 0.5 ppm frequency stability
  • 505 memory channels
As with any new technology thses parameters are probably sucject to change before market launch.

It will be interesting to find out more about this new radio and its performance on 70 MHz especially with respect to:
  • Strong signal handling capabilities, e.g. OIRT signals
  • Variable power control and overshoot management to avoid destroying external power amplifiers
  • MGM performance
  • AGC off, fast, medium and slow
  • Transmission from 69,9 MHz and to 70,5 MHz
  • Split operation
  • Heat disipation and long time transmissions

More information is likely to surface with time.
