I have a Collins R390URR and am beginning to fire it up after it having been on the shelf for about 20 years. It is dirty and all switches seem dirty and noisy. At least, it makes ambient noise without an antenna connected.
I am finding more information regarding the R390A than the R390/URR. I would like to have someone run down the major differences between the two models. I am interested in the MAJOR differences and how they affect the performance of each. I am not trying to necessarily own the "ultimate" of the two, but need to know what to expect from my old R390/URR and whether I will be happy with it in my Amplitude Modulated station. Great detail isn't necessary, but general information will be appreciated. Thanks and 73, John, K5PGW ____________________________________________________________________________________ Looking for last minute shopping deals? Find them fast with Yahoo!
