Personal thoughts on local communication companies.
So.. We have tried working with lots of Vendors in and around the area unfortunately most of them are not exactly Ham Radio Friendly.. But I have one special exception VEI Communications out of Evansville Indiana. There amazing service and skills that they demonstrated place them at the top of our list for local ham radio and commercial radio solutions that we may have.
Thank you VEI Communications!!
