Hi. GP7 controls (turns on and off) various devices, such as a relay that switches to another antenna. For example, during reception, you can compare which antenna provides better signal quality. Additionally, on lower frequency bands where additional receiving antennas are often used, you can switch between the transmitting antenna and an additional receiving antenna.
This functionality can also be utilized, among other possibilities to control other types of devices, such as turning external preamplifiers on or off, changing the direction of a two-element antenna array, or managing a bidirectional beverage antenna.
The primary purpose is to switch between the RX (receiving) and TX (transmitting) antennas during listening. This feature is commonly found in high-quality transceivers and can be adapted for various creative purposes based on imagination and specific needs.
The documentation provides clear instructions on where to find the control voltage point ( 3.3 V) on the printed circuit board. You can solder a connection pin (there is a hole in the printed circuit board) or solder a wire to that point. It’s essential to adhere to the specified maximum current loads, as outlined in the documentation.
