I am checking on that right now to see if we can get a greater spread. Will keep you updated. Peter Summerhawk

What I got for a freq spread is: 151.835 and 153.020 so I can t use a duplexer and will have to run a dual antenna system. How far apart do I have to mount these to make sure they work ok? I have a Motorola RICK to use and want to have the units programmed for around 15 watts or so that way I dont burn out the radios when we really need it. I am thinking that the 153.020 is going to be repeater input and the 151.835 is the output. I will be running DCS on the system to avoid problems with the system. The radios (CP200) are going to be programmed with MDC1200 signaling as the supervisors carry a HT1250 so they can see who keys up and if there are any problems. I need some help on getting the antennas set up and I can program the rigs for the repeater use so no problem there. Thanks Peter Summerhawk-N0WRE That split (under 1.2 MHz) is a little close for a baby notch-only duplexer. Can you get a different input frequency further out? If you can get a 4 mhz or so you will find it is much easier and much cheaper to make it work. A while back the Canadians surplused out a BIG bunch of high band MSR2000s with 4-5mhz duplexers in them (inside the MSR cabinet), and all of them that went into amateur service had them [The entire original message is not included]
