My friend and I want to see if we can Ham radio between San Jose, CA and Bangalore, India. We're beginners and are going to be using handheld radios. Are there any networks of repeaters, that could connect us, or could you suggest a resource to find them.
You should consider whether the Internet Radio Linking Project (IRLP) could eventually meet your goals. There are currently a dozen or more IRLP nodes for the 2M, 70cm and higher bands in the San Jose, CA area. However, there are currently no IRLP nodes listed as active in India according to the www.irlp.net site. It's possible that there is a country/region-specific regulatory issue that is preventing nodes in India. If there is no regulatory roadblock then you and your friend could maybe be the ones to establish an IRLP node in Banglore and put India on the IRLP map.
The only way this would work would be to use a longer wavelength, 6M at the minimum, but more likely 15-20m. HTs don't come in that size.
As far as using repeaters, you might be able to find one that connects over the internet. I'm doubtful that such a thing exists, but it might.
