I click import on chirp and it gave me an error saying invalid zip code. This caused me to go to the main repeater lookup page on Radio Reference. When I put in my zip code nothing comes up. However I can click on Nevada and zoom into my areas and find the city etc. it’s like the zip code isn’t in the system.
If I go to the main database page and "Retrieve by US zipcode" using 89703, it takes me back to the main database page. That ZIP Code is one of a handful of codes used by Carson City NV. So, I tried the same thing using 89701 which is also Carson City. Same result...back to the main database page.
As a test, I used my own ZIP Code in Indiana and the system takes me to my county's database page.
The link you provided is the city not the county. Carson City should be listed as the city and county. Most imports are done by zip code crossed with county.
