About to start going though the process of mounting up my antenna and radio I pulled from my Jeep. Haven't found a lot of info about moutning HAM radios in 3s in general and especially MS3s. So I'll be winging it mostly. I'm going to figure out what to do with radio itself first and see if I can track down a YSK-90 separation kit for my older Yeasu FT-90R. Advantage of the FT-90 is it's very compact even if I have to mount the whole radio somewhere. I'm leaning towards under seat for the radio body and up on the "info" center for the head unit. The PO put in an aftermarket radio so the info panel on the car is largely useless other than HVAC control. I've got a few extra antennas laying around so going 1/4 or 1/2 wave will be easy enough. Just need to decide where to mount antenna. Ideally I'd do an NMO though the roof but I don't know if I want to drill a hole in the top of this car lol.
