Just for a different take on this, since the frequencies you want to transmit on are looking good, and you are never going to transmit on 465, I’d just let it go and give it a try.

For me, FRS radios and GMRS radios were useful before I got a cell phone in 2001. I am licensed for GMRS, and amateur radio. I also have a license for operating radios aboard ships and aircraft. My first license was GMRS. I like GMRS because it can be used for communications amongst family members and friends with their own licenses. The conversations on the radio service tend to be more communicative rather than hobby related. I head over to the amateur frequencies to hear technical discussions regarding antennas and radios. GMRS is useful when hiking biking sailing and driving. In emergencies, I hand out FRS radios to my neighbors. This lets them keep in touch. I have had to use my Winlink radio service to help neighbors to communicate with family members during a severe ice storm years ago. A similar land based HF service (not CB) like GMRS would be nice to have.

I'm a newbie also and playing around with elevations I ran across https://www.scadacore.com/ A line of sight that works where we have only rolling hills. BUT it is a very quick reference I find. Also quite accurate for the price (free). LOL
