Good advice from @Mike. AllStar has a pretty steep learning curve. Baby steps at the beginning are advised.
Another alternative to the Masters Communications products is the URI from DMK Engineering. These are long proven devices and long time friend of the AllStar inventor Jim Dixon, WB6NIL. See the link below if interested.
Personally, I’m a big fan of the RTCM. The web site is down due to what I’ll call a business dispute. But the product is still available. PM me if interested. I would say that the RTCM adds another level of complications that may not be desirable to beginners. However, it’s voting capabilities among other features are where you want to be eventually.
