While you could wire only one of the freqs to a pigtail (HF or LF) and try to use it; there is no software setting that would properly give the right power and freq sweep to properly support it. The B265LH will be a deal for someone with the TZT3 (12, 16,19, or BB) or someone with DFF1-UHD. It just isn't the right fit for the GP1871F/GP1971F.
