Is there a Ham Radio Outlet near you? They can help you, they are knowledgable and expensive. I found a really cheap Icom 207h used on eBay
. It is similar to Yaesu FT 8800 in being that it has a remote head. I love this radio, for the price. It is dual band and modded for 120mhz all the way up to 480mhz. I have a dual band antenna with a NMO mount on the center of my roof. If you are looking to work repeaters you don't need much more than 5w. So don't get caught up thinking you need a lot of power. The only other advice I would give is to run a relay with a fuse on the ACC. If you get a remote head unit, the back seat is a great place to hide the transceiver and easy access to run power lines and coax.
Dual receive is When a transceiver can monitor two different frequencies at once. Usually one for 2m and one for 70cm. And 10M is a HF
band, a tech license gives you some privileges here. Also CB Radio is within the 10M band
