Yes, RT Systems is not cheap, but it has always worked for me, both with and without their cables. However, I have never had a problem with their cables, which is far from true with a generic or CCR cable. CHRIP has been useful, but did not work as smoothly or at all with a couple of radios. I have never had a problem with downloading or installing on a new or second computer. My only complaint is there is no way to transfer the RT package if you sell the radio. -Even a $20 re-license fee could give the new user a better start.
