<<<ÂÂ I think I hear just a little less signal strength

indeed. Â Now, if there actually is a little less
signal, maybe the CC Skywave would handle it? (Do
I recall it folds under the onslaught of the 3" FSL?)ÂÂ >>>ÂÂ
Thanks for your relative signal assessment, Nick. Of course,Âas long asÂthe 2" FSLÂprovides stiff competition for the larger and heavier 3" FSL model it is already a significant design winner. Most of the comments so far seem to place the two models at nearly equal sensitivity.
Â
There have been two FSL transplant experiments in the CC Skywave so far-- one a 3"ÂFSL transplant and one a 2" transplant. Unfortunately neither one has proven successful. C.Crane's custom DSP chip apparently is incompatible with the potent RF output of these hard-wired FSL antennas, causing overloading in the 3" FSL case (and resulting destruction of the chip), and mediocre performance in the 2" FSL case. The 2" FSL CC Skywave provides MW sensitivity inferior to that of a 7.5" loopstick CC Skywave model-- not a very good outcome at $95 a shot. As such,Âthe CCÂSkywave has pretty much been written off as unsuitable for this hard-wired FSL experimentation.
