SINGLE-SIDEBAND HANDHELD AH-100

Channel Modification:

1: Remove the Back cover.
2: Locate the small curcuit board that has the PTT, up, down, lamp buttons.
3: On the back side of the board, toward the bottom outside edge you'll see three curcuit lands that just END.
4: Solder a bridge across all three curcuit lands.
5: The modification is complete, BUT!
6: Put the back on the transceiver.

- If you have used the radio prior to performing this modification you will have troubles activating the feature. I had to leave my battery removed with the power switch in the ON position, with a shorting jumper across the battery supply clips for 24 hours. This made the microprocessor loose its brain. While leaving the radio power switch in the ON position and holding DOWN the CH9 button, slide the battery pack on the Unit. Remember to kepp holding down the CH9 button for at least 2 seconds after sliding on the Battery. At this time you'll see that the Display is blank, but the receiver is active, when you release the CH9 button the display will return. Now you are there. Using the CH9 button to select bands A, B, C, D, -E is not shown- as it is the normal band, F, G, H, I, J... Thats right 400 Channels. It covers the entire 10 Meter Ham Band!

BTW: At this time, and once you have got this function working, it is only Neccessary to power up the unit using the CH9 button held down to activate the feature, you do not need to drain the battery again and again. In fact if you perform the modification first, before you ever use the unit you may just slide on the pack after doing the mod. Then power up Holding down the CH9 button.

MORE: If you power up the unit without holding down the CH9 button the AH-100 will just operate normally. Just turn it off and power up holding down the CH9 button to reactivate the 10 bands of operation.
