I'm not spending hundreds of dollars on a radio that must be modified to work as advertised. no problem. but aren't you this electronics guru? imagine a machine shop owner buying his car based on stock horsepower while balking at someone bolting on a supercharger. what can you hear on your RX340 that you cannot on your R8B? on an R75? please site specific specs. we all know the answer and that is why the R75 is now one of the best selling tabletops. I haven't noticed anything that the RX340 can pick up that the R8B can't hear. Usually the RX340 can make a station sound better but other times the R8B does better depending on conditions. The radios are all on different antennas, which make for a different reception condition so I am not generally comparing them. Thanks for this one.Using simple logic if your R8B [$1,499] can "pick up" anything that your ten tec RX 340 [$4,000]hear,then my Icon R-75 [$450=$70.00 in mods=$520.00]can run side by side with your expensive Ten Tec [because my R-75 was better [in a real life side by side test] in hard core dxing than my R8b [sold after that]. I would not be buying a new car and modifying it either. An older out of warranty car could be a different story. In my youth I was into street racing and did just that. I bet that my toyota [r-75] can run side by side with your your mercedez [ten tec 340] Some people just don't understand that anything manufactured has engineering compromises built in. Each radio when designed has a slew of compromises where one performance parameter is diminished in favor of another. The result is that depending on situation and conditions one radio will do better than another. Change the situation or conditions and the other radio does better so which is best? I agree with you 99.9% That was my point in all this tread.At last you got it. You generally get what you pay for. Spend more money on a radio and you can get higher quality components resulting in better specifications, reliability, capabilities or operational features. This is the great myth again price=performance.Better specifications? Tell me about your ten tech RX-340 dynamic range /IP3[5khz]or blocking capacity. |

Thanks Steve, you are correct I forgot a "h".I'm writing too much this days and sometimes I forgot a letter or some coma. But I'm a fortunate man I have you at my service as my personal secretary and the nice thing is that I don't have to pay you anything... |

hi Telamon:
how would you characterize these RX340 specs? IP3: 5-kHz -53 dBm, 20-kHz +4 dBm phase noise: -113 dBc/Hz ultimate rejection: 70 dB regards, phil ![]() |

In practice you might think I would have a problem listening to a weak station with a strong station on the next channel over but I haven't noticed it. phase noise: -113 dBc/Hz It would be nice if it was -120 down but it appears to be low enough because the receiver noise floor can be 1uV. ultimate rejection: 70 dB It is supposed to be at least 70 dB but depending on how you use the radio it is actually much greater so the ultimate selectivity is better than this number makes it look. -- Telamon Ventura, California |

hi Telamon:
my purpose was not to belittle. you're correct, specs can be deceiving. does someone sell a $600 K2 for a $3300 Orion if under their conditions it yields only 0.2% more IDs? possibly. you would be successful with any receiver because you understand RF environment, antennas, propagation patterns, etc. regards, phil ![]() |
