Greetings all,

I have enjoyed reviewing numerous posts on this group over the past several?months,?especially as I plan and have started a build of a 25W iCOM ID-2010V based mobile repeater on VHF.

I'm writing to ask for pointers on finding a duplexer to purchase.? I already own the iCOM repeater controller.??

My application is primarily?for portable use, supporting both Olympus rally and Oregon Trail Rally in WA and OR respectively.? Recognizing the challenges of a VHF portable, I have a trailer in hand with an onboard power system, mast, antenna, and enough space to mount and travel with a full sized 4 or 6 cavity system.

Requirements: 25W and .6MHz frequency pair spacing.

Please go easy on me as I am ~4 year HAM and this is the first repeater I have worked on from scratch.? I've spent some time with local clubs at repeater sites and have worked in partnership on a DIY dispersed 2 site repeater using 2X TYT 9800s in VHF config with UHF crossband interlink before.??

Any help?would be greatly appreciated, specifically sourcing?a duplexer best suited for portable, and advice on mounting it for vibration mitigation.? Perfectly happy to purchase and adopt used equipment in good shape.? I also welcome advice on what models or types to shy away from.

Lastly, if you are in WA / OR and interested in volunteering for Rally Communications support, please have a look at my QRZ.

73 all,

Devin H.
