### Band selection

The RepeaterBook query dialog allows you to optionally filter by band, such as 2m, 70cm, etc. Note that the list of bands is populated from your bandplan selection (*Radio* -> *Select band plan...*). If you only see one or two bands in the dialog, make sure you have selected the appropriate (usually "North American") band plan.

1. Query each state that could be in your final distance (aka proximity) query
13
1. Modify the last Chirp query to use latitude, longitude and distance (miles) - you'll still need to have a state selected but the cache will provide other state's results too
14
1. Execute the distance query

Explanation

18 5 Dan Smith
RepeaterBook has a distance based query called Proximity 2.0 that returns results from multiple states, Canada or Mexico but does not have an API with the same functionality.   Using a multi-state query might trigger rate limiting by RepeaterBook.  Chirp stores (caches) query results from previous queries.  Instead of creating a new query Chirp will search the cache for the proximity results using longitude and latitude.
