excellent receiver test
"mike maghakian" wrote in message
... the serious problem with deep skirted filters is that the audio will stink ! besides almost no receivers are sold with deep skirts, most have the cheapest piece of garbage they can find. Don't know of any receiver sold in the past 20 years below $500 that had decent filters other than the S800 or E1 I would suggest that the interferer would have to be transmitting on one sideband only for any receiver to be able to pull out the other sideband of the desired station, if the carriers are co-channel. In which case, lots of radios with fairly steep-skirted filters would do fine. So the S800 and E1 filters do not have 'deep' skirts but somehow do the needed sideband suppression and sound better than 'fairly steep-skirted' filters? The demod is not doing the interference suppression unless I'm missing something. There is a logical inconsistency here..... Tom |

Debatable, but with PBT, or even a tiny detuning, this problem is largely eliminated - and some receivers in that price range and up have the PBT feature. One must use whatever tools one has to achieve copy. Bruce Jensen |
