Just wondering if RF is out of business or what. I know they have the Magnum1 out but that's it. I know that their RFX modules were popular as well as their radios. I was really hoping they were going to come out with a better and improved version of the S45 or 257 radios. I have used their extreme 2018 mic for years now,I really like that mic. Anyway, I was looking to buy another one and see that all places are out of stock of them.
