Hello Sailors, As I replied direct to John, the "trend setters" statement was made tongue in cheek. His reasons for their bandplan make sense in rural areas. When you get into large metro areas, all the rules go out the window at busy mountain tops and repeater sites. You just can't hide from that nearby 1/4kw paging transmitter...
Receiver distribution and transmit combiner systems become a lot of science, experience, budget management and magic with mirrors. Regarding Juan's comment below. The micor mobile makes a great repeater when you keep the in cabinet desense under control. Cutting the channel element crystal for the proper injection and tuning will determin high-side/low-side tx-rx. Changing the offset crystal will modify the original motorhead 5 or 3MHz tx-rx spacing. If you buy a poor quality channel element crystal, both the receive and transmit frequencies will drift as one. We used to call these "VFO Repeaters".
