If this still does not work for you then I suggest buying a professional grade radio with digital filters in software preferably in the IF chain. You will pay a lot more for it than the Drake. You can get a superb DSP receiver for around $500 if you try hard enough. http://www.rfspace.com/SDR-IQ.html |

I have trouble understanding anything them wimmins say.(maybe I might go
to Chat Universe, Sexy Playmates, in a little while and rant with them lezzies for a while,,, Sue, I Love you,,,,,) Seriously though, can a computer speaker with adjustable thingys on it be plugged into a Drake, (I don't own a Drake, wish I do) would that work alright?

Yes, I turn the tone control fully clockwise and move the passband tuning too, but I cannot get improvement in weak signals.
I have tried with a multi mode audio filter, a Datong FL-3, no results. With respect to the antenna it is a Wellbrook 1530+. Now, I hesitate in buying a R7A or a Collins 390A and to selling the R8b. |

It won't solve your problem, since I had the same issue with not understanding speech from weak tropical band signals with my R7. I had a Sherwood SE-3 synch detector (your R8B has a synch built-in) and ran the audio out to a good speaker, but still it was too bassy. I thought about using a graphic equalizer to adjust the tone. Here was some great advice I received on this forum years ago: "If bass rolloff is only what you're after. There is a simpler way. Put a non-polarized capacitor between the R--7 and the speaker. There are numerous nomographs for picking the right cap for your situation in most any radio handbook. Audio handbook, too, for that matter. But you'll likely want to cut and try anyway. Its simple, cost efficient, and it doesn't require a ground, so you can do it with most any radio." I went to a Radio Shack and looked through the catalog for the low cut- off frequency of different capacitors, and just attached one wire to the capacitor on one end, and put the other end into the speaker. Huge improvement. Experiment with different cut-off frequencies for your personal taste, shouldn't cost very much and certainly cheaper than a new rig. |

It can get down to personal preference. I had a Kenwood R-5000 years ago
that I KNOW was superior to anything else I have ever owned,. Sensitive, solid selectivity, many tuning and filter features, and like you, I tried and built speakers, headphones and whatever else I could do. But, I HATED listening to it after an hour or 2. Just something psych-acoustic, whatever. I later got Yeasu FRG-8800 and after a lightning hit, the FRG-100. Later, a Lowe 225. Admittedly, they might be considered a notch down on qualiity, but the important thing is: I am happy with them. You might try tuning AM stations off-freq a couple Khz as your filters may allow, to get the audio into the higher range, but this is not really possible on SSB unless the Drake has a carrier offset tuning (as does my FRG-100). And, I really doubt if the AOR is any more sensitive than the Drake in the real world, this sounds more like an antenna issue. Tropical bands like long antennas. |
