- OUT OF BAND MODIFICATION OF THE ICOM IC-24AT
-
-
- The Icom IC-24AT is truly a remarkable unit. Having it's
- genesis in the IC-R1, Icom's extremely wide band Hand Held
- Receiver, it is capable of receiving a wide range of frequencies,
- as well as being able to transmit on short excursions, outside of
- the amateur two meter and 440 MHZ. bands.
-
- The more current models can be modified to receive out of
- band, by a simple software (not necessary to physically open the
- transceiver) procedure as follows;
- o Turn the power switch off. While simultaneously holding the
- "light" button, the "B" button, and the "#" button, turn the
- radio on. All elements of the display will light up.
- Continue holding the buttons until the display goes out. It
- may be helpful to have a buddy give you an extra hand during
- this procedure....Your unit will now receive out of band.
- The older models of this transceiver, require the removal of
- diode D13, before performing the above procedure. D13 is on the
- main logic board and is a discreet diode near the center of
- the board. It is the diode on the left of the two on the board
- when the radio is open and held with the controls away from you.
-
- The "stock" transceiver, was also not designed, to provide
- full direct keyboard entry of the operating frequency. This can
- also be modified by one or both of the two procedures below;
- o To directly key in the 10Mhz. frequency, simultaneously hold
- the "light" button and the "2" button, while turning the
- radio on.
- o To directly key in the 100Mhz. frequency, simultaneously
- hold the "light" button and the "3" button, while turning
- the radio on.
