We also use Avalan 900 MHz radios for a number of our broadband stations with great results and for all the reasons Juan states.

Hi Mitchell

We have been using Avalan (900 Mhz) radios. They are not expensive, we use also filters with these units to avoid interference. The maximum range that we are covering now is 17 miles around 27.4 Kms. They can be use for outdoors also. They are like plug and play easy to install. We used before the EV-1 but they are more expensive.

I hope this will help you. If you need more details just let me know.

Best Regards
Juan Lugo

I recall a few people mentioning EB3-Plus radio failures at the meeting, and I was wondering if someone could mention what failure modes they're seeing? We have had a few that become non-responsive even after rebooting, come up in error, and some of those have recovered inconsistently after multiple power cycles. In a couple of cases it also appears the RJ-45 is not working. Do these sound familiar, and are there any possible fixes (hardware or firmware)?

Are there any suggestions for a 900 MHz replacement?

Regards,
