Talked with my contact they are going to see if we can get a 151/159 split to better suit our needs. Will keep you posted on this.

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 don't 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 ripped out and shelved. If you can bump the receive channel further out then one of those ex-Canadian would scratch your itch just fine, and the seller would get some shelf space back, so it should be pretty cheap as well. I wouldn't mind finding one of those myself - I have a use for one. The repeater transmit channel would be in the 151-152 area and the receive channel would be in the 156-158 area. Mike WA6ILQ
