I have obtained permission by the Rocky Mountain Radio League to link my AllStar linking system node to their repeater via RF or on the input frequency.
Since they have such a long tail, they will stop the transmitting tone immediately so I can base the operation on the tone.
With a simplex link, I would just have the radio programmed to transmit and receive on two separate frequencies just like anyone else would link in to the repeater.
With full duplex, someone on the internet link could still talk even when the repeater is transmitting something (maybe an announcement etc.), but the disadvantage is that the remote link has too much control and trolls could come in and just double with everybody.
Should I go with a simplex link, or go with the extra efforts of another radio and some sort of filter (duplexer, diplexer, band reject, band pass, high pass, low pass don't know which one)
