I haven't dug into this receiver yet, but it seems to me that the 2.4 kHz SSB filter is bad. R-4C, late serial number.
* Using the S-meter, the signal strength of the calibrator is lower in 2.4 by 10 dB, than the reading in both 1.5 and .5. * The decrease in gain is solid and not intermittent. Rocking the MODE switch doesn't reveal any changes. * It's also a noticeable loss listening on-the-air. I see what appears to be the filter on the top side of the chassis, under where the two carrier oscillator crystals are. Has anyone had any grounding issues with this filter that have fixed a similar problem? I figure if there's a bad ground, it could affect the insertion loss of this filter. If it's bad, then comes the pain of finding a replacement. If anyone has an extra one for sale, let me know. Steve Wedge, W1ES/4 Live free or die: Death is not the worst of evils. John Stark.
