Folks - I'm not sure if this is a sale for everyone, or just directed at me because I have been recently searching Amazon for CBs - but I'll offer the link just in case you can use it.
It's not an affiliate link (I'm not signed up as an affiliate).
Hope it is useful for anyone considering a CB purchase. I notice the Uniden 520 is on the list. That's one of my personal short-list units for truck & base. The HomePatrol units are also on sale.
