IC24AT.10
I received the following mods for 24AT out-of-band from a very reliable
source (although they don't specify RX only or RX/TX), for 75-195 MHz,
200-490 MHz, and 740-960 MHz. Rumor has it (unconfirmed) that the unit
even switches to AM in the air band!
1. Remove diode D8 [see figure below]
2. Attach diode D7 [I believe this is already equipped]
3. Attach diode D12
4. Remove diode D13
5. Simultaneously hold "LIGHT", "B", and "#" keys and turn the
power on. Release all keys after the display goes out (checks
all LCD segments). [This is supposed to enable the
out-of-band frequencies above]
6. Simultaneously hold "LIGHT" and "2" keys and turn the
power on. This enables the 10 MHz frequency digit entry.
7. Simultaneously hold "LIGHT" and "3" keys and turn the
power on. This enables the 100 MHz frequency digit entry.

of the other. Top pin
