I might catch some slack for this but oh well.
At only max of 5 watts which really is like 3 1/2-4 watts, no one on a ham band is gonna be throwing a bitch fit about “bleed over”. All radios have it in some way shape or form. On 2m/70cm 98% of operators will just kick up the power a bit of need be as non qrp rigs, have a base minimum wattage of 5-10 anyways.
Since 90% of 2m/70cm is done on repeaters anyways You shouldn’t have any issues with what you are wanting to do. Only a select few repeater owners are douchebags and only a small percentage of ham operators are die hard (insert a big name brand here like Kenwood, ICOM, etc) folks will bitch about what radio you are using. The rest won’t really care what you are keying up with as long as your legal and not an ass.
Since a lot of my outdoor activities is mainly hunting in the West, and in places that cell phone service is laughably non existent, the Asheville, Jefferson (West Jefferson maybe), Sparta, Wilkes, Maravion Falls, Lenior, Morgantan, and a couple in VA, and TN repeaters are all programmed and for the most part have had no issue hitting any of them with my B6. Someone is always on a repeater. Actually NC have one of the most active repeater areas in the US.
@htperry is a really good gent. He is very passionate of ham radio stuff and does have legit concerns about interference. And not kissing ass or anything but he is very knowledgeable in the area as he has helped me when I first started out when others wouldn’t or couldn’t at the time
FRS, GMRS or whatever is a different story as they are low power for the most part. I don’t use them, it has never appealed to me so I’m no help there. but since they are of lower power, interference is a big concern. Hence why just jump through the hoops once and get your ham licenses and just renew every 10 years lol
