I am interested and have started preliminary research in sending instructions to the CPU of PTT radios over the air. Specifically, I am focusing on ICOM V68, V80, and V82 radios. I want to be able to do so without having to make modifications to the receiving radio. If anyone has any ideas or a good idea to get my research growing, it would be greatly appreciated. Thanks in advance for any help that can be provided.
More info needed. First, are you a licensed amateur radio operator? You cannot use these radios without a license. Regrettably, none of these radios have that capability.
There are other radios out there that allow some minimal control from another radio. These options are limited to disabling the radio, and remote deactivation of the transmitter. Look at the Wouxun KG-816 and see if that is somethng along the lines of what you want to do.
