IC-705 Interface ATU Upgrade Kit

Here is a new update for the HobbyPCB Hardrock-50 IC705 Interface kit that will make the Hardrock-50 appear to be an ICOM ATU attached to the IC705 and allow all of the tuning functions in the radio to operate the Hardrock-50’s ATU. This kit contains a preassembled PCB, pin header and a 3.5mm cable that can be used to modify an existing HobbyPCB Hardrock-50 IC705 Interface kit. This is an upgrade kit only, you must already have the HobbyPCB Hardrock-50 IC705 Interface kit, ICOM IC-705 radio and Hardrock-50 amplifier with ATU. If you don't have all of these things, this kit will not help you!
