Well Ganesan, with the advent of cheap Chinese handies available in the 2-3 k bracket, is it worth    making a 2 m receiver, which will cost 2k+?
  A hf rx for 40 or 20m or a cheap DSB trx for 40m will bring in interested home-brewers.

  • Rotary encoder for tuning
  • Selectable tuning step size (5, 10, 100 kHz and 1 MHz)
  • PLL synthesized tuning
  • Full microcontroller controlled band scanning capability
  • Dual conversion superhetrodyne (10.7 MHz and 455 kHz) with Crystal and Ceramic IF filtering
  • Squelch function
