TRICKING THE ICOM R71A TO TUNE BELOW 100 KHZ
Bob Parnass, AJ9S
The ICOM R71A general coverage receiver is designed for
VLF reception down to about 97 kHz.
The following steps will confuse the microprocessor-
based controller sufficiently to permit reception down
to 0.0 kHz:
1. If all 32 memory channels contain frequencies,
use the FUNC and CLEAR buttons to clear a memory
channel.
2. Place VFO/M switch into the M (Memory) position.
3. Using all the manual dexterity you can muster,
rock the MAIN TUNING knob back and forth, while
simultaneously rocking the MEMORY-CH rotary con-
trol to switch back and forth between a memory
channel with a frequency in it and a clear memory
channel.
