Re: BCT15X Sensitivity

Walter Rymarczyk

I have a Stridsberg multicoupler, it’s amplified.  I find my 536 works better with the supplied whip antenna than with the discone on the multicoupler.  I think the multicoupler overloads the already sensitive 536.  It works well with my Icom 8500 though.

This mulicoupler, is it buffered by each having an built in attenuator? If not it could be an input impeadance/loading issue.

Try the discone direct to the radio first, then comeback.

This venerable analog-only model is still being offered new, and I recently purchased NIB from reputable electronics retailer. Primarily for civil/mil airbands. My attic discone feeds the 15X and 3  ICOM receivers (7100, 8500, 8600) through a multicoupler, so all are receiving the same signal. 15 miles from BWI the ICOMs clearly pick up transmissions that the 15X does not hear; even some controllers are breaking squelch with S-5 signals on the ICOMs, the Uniden hears nothing. The same with many aircraft comms; parking all receivers on the same freq. the ICOM misses what the others hear. Close Call is disabled and there is 0 attenuation. Am I overlooking another setting? Using ProScan. Thanks.
