Hi Frank,
I've had pretty good luck with mine, so I am not sure what happened with your units. As far as the 455kHz I.F. there were a couple of engineering changes. First of all, that 270uH inductor was replaced with a tunable unit. Next, there was a .047uF coupling capacitor that was changed from a leaded unit to an SMD type. Apparently, there was some radiation from the cap. I haven't experience that problem with my unit. As far as sensivity, both my HF-150 and my R30 are in the .1uV range..........when the whip amp on the 150 engaged, the sensivity improves to .04uV. I haven't used my comm receivers very much, instead, using the Grundig 3400 as a bedside radio, but that can change, depending on moods. Pete wrote in message oups.com... I must have been doubly unlucky with the R-30 because I've had two of them and they were dogs! They both had massive birdies and an unstable IF, not to mention vastly inferior sensitivity to the HF-150 that I compared them with. I actually liked the feel and sound of the R-30s but even my old FRG-8800 ran circles around them. Frank K3YAZ Tucson |
