- Keywords: ic2sat mod

- Modifying the IC2SAT for extended receive is very simple if a certain diode
- was not installed at the factory, as was the case with my 2SAT.
-
- Turn the radio off, simultaneously press <#>,<B>,<light> and turn it on. (The
- <light> button is not labeled, it is on the side under the wrist strap.)
- Release those three buttons after the radio beeps. (I think that mine beeped.)
-
- It can now receive over three large frequency ranges and will receive AM
- aircraft band transmissions acceptably. Experiment to find which frequencies
- you can get. The memory channel number will display the letter "U" to show
- that the PLL circuit is unlocked on frequencies that cannot be received. It
- will tune from 0-1300MHz but the operable ranges are not that big, its highest
- receiving freq is a little over 300MHz.
-
- If that doesn't work, a diode will have to be removed. It is a glass diode
- mounted on the PTT switch circuit board, and I think it is the only standard
- component in that area. It is mostly surface mount components.
-
- Standard disclaimers apply, since I cannot be responsible for whatever you may
- do if and when you must remove the front to look for a diode. (The owner's
- manual explains how to open the 2SAT.)
