Convert 2 Kenwood TK-880s to a repeater

[WREZ930]

I have two spare Kenwood TK880H radios that I would like to convert into a portable GMRS repeater. I know I need a duplexer and controller, but what do I need to interface the two radios, and how exactly do I do that? Any help is greatly appreciated!

I used a surecom SR-629 (https://www.amazon.com/Gam3Gear-Surecom-SR-629-Repeater-Controller/dp/B01M0KVOC2) with two K1 cables (http://www.409shop.com/409shop_product.php?id=122463)

Only thing I recommend is that your TX radio be reduced to low power only if you plan to have a bit of traffic on your repeater, I would also set the TOT to about 60 seconds. This will prolong the life of the transmitter and prevent burnout. I run the standard 880 (25W) and I set the low power out to about 10W which for portable use is perfect. Outside of those two things, you don't really need to do much to the radio, its all plug and play.

Thanks! Would you please provide a connection diagram? My email is good on QRZ.

QRZ is not letting me log in today However if you PM me here I'll shoot an e-mail to you right away. For the most part its all plug and play, no radio mods or anything, just uses the mic port on the front of the radio and the speaker port on the back.
