1 Upgrade Manual

There are two levels of upgrade possible with this kit.

This level of upgrade adds the PACTOR and ARQ6-90 modes. Level 1 upgrading is suggested for those interested strictly in H.F. (shortwave) modes. This level merely requires the replacement of the "plug-in" EPROM.

This level of upgrade adds the PACTOR, ARQ6-90 and ACARS modes. This level of upgrade requires replacement of the "plug-in" EPROM and the solder installation of two resistors (supplied). The two resistors are required for proper ACARS demodulation. ACARS is a VHF mode. Therefore those interested strictly in H.F. monitoring, may prefer to do only a Level 1 upgrade.

Please note that re-alignment or calibration of the unit is not required for either level of upgrade. This upgrade is only for v1 and v1.5 owners.
