I nice thing about Ham (amateur radio) dual band radios is that there are NO preset frequencies. You can choose frequencies anywhere in the 2 meter / 70 cm bands. You can also use repeaters (which are free) which greatly increases your range. The technician level license is easy and worth getting. You will for like $15, be given a license good for 10 years and call sign unique anywhere in the world. It's worth the time investment. The test is not difficult and well worth it. There are very good dual band handhelds you can get on amazon for $48.

Where did you mount the SL-One ? Tnx much - I really like your set-up and would like to duplicate it.

These VHF/UHF radios primarily use the business frequency spectrum in the VHF range.
The Rugged Radios also have GMRS channels pre-loaded along with most of the team channels from Baja or KOH.
The business license gives a business the usage of that frequency in their area and no place else.

You can search the FCC site for frequency usage by a business in your area.

As a club you could get a frequency for your area that you plan to use the radios.

You actually just can't pick any frequency you want in 2M/70cm, the FCC has a band plan that you need to adhere by.

True, but at those high frequencies, there are many more frequencies you can choose from. With a phone bandwidth of 3 to 6 kHz, many frequencies to choose from.
