QODOSEN SR-286 vs. Sony ICF-2001D selectivity comparison. August, 12 2024 1740 UTC
Переглядів 5992 місяці тому
This comparison shows the shortcomings of the QODOSEN SR-286 when it comes to selectivity on AM vs. the vintage Sony ICF-2001 D with its unsurpassed Synchronous Detection function. In this example, RNZI (New Zealand) on 9700 khz is much weaker than the booming RCI on 9695 khz from the strong Kumning Anning transmitter. The Sony separates the two stations pretty well, no chance with the otherwis...

    After I replaced transistor Q303 and lifted the leg up on L302 resistor my 2001D was so much more sensitive than the Qodosen.

    • @charlesfeinstein7035
      @charlesfeinstein7035 22 дні тому

      Isn't L302 an RF choke (part of a hi-pass filter) and not a resistor? From what I have read the main impact of lifting this choke is on the upper part of the AM broadcast (Medium Wave) band and not the shortwave bands.

  • @dxace1
    @dxace1 Місяць тому

    Stephan -- not sure what the point of this is. The 2001D is a fundamentally different radio. Only NAR/WIDE selectivity. You're showing the SONY using SYNC whereas the Q does not have SYNC. And you only show the Q using one bandwidth (3 khz).

    • @stephank.8453
      @stephank.8453 Місяць тому

      Sure , I know, in some way it's an "apples with oranges" comparison. However, to my understanding it's not forbidden, to compare oranges with apples. Sometimes, there even is a point....here, I wanted to demonstrate the power of an excellent SYNC function. I chose the smallest bandwith only with the Q (3khz), because the result with the wider bandwiths was even worse. I would not consider the Q's filter as excellent, the cheaper XHDATA D-808 (also w/o SYNC) is much better here imo.

  • @barmaley-division
    @barmaley-division Місяць тому

    D-808 has more pleasant sound than SR-286, wider, more treble probably. Same sensitivity on SW.👍🏻

  • @barmaley-division
    @barmaley-division Місяць тому

    I own 5 cheap DSP receivers and I have the same issue; I thought it wouldn't be possible to receive RNZ on this frequency. It turns out the Synchronous Detection function may help (if available). Thanks for comparison. 👍🏻

  • @barmaley-division

    Of course, an owner of Malahit SDR V3 would not need anything else for AM. TEF6686-based receivers are very good for FMDX'ing, rest - SDR & NR=ON. 👍🏻

      ​@@HardcoreDXLithuania Anything can be compared to prove a hypothesis. For example, "Synchronous Detection provides better selectivity on weak signals" here.

      And of cause remembering the radio of 70-s, tubes based, it's not copmarable to any modern . And SDR is even worse for long distance reception. I own around 10 different SDR in price range 50 - 300 Euro. It's just huge dissapoitment comparing to what I remeber was receiving with old tube based one.

    Got out my Qodosen SR-286 this afternoon to see what AM stations it could pick up in daytime in central Texas (I did previously at night, but not yet in daytime). We've got quite a number of AM stations here, including several 50 kW clear-channel stations. The 286 picked up only _two_ stations, and poorly at that. It didn't even receive 50 kW WOAI in San Antonio, just 70 miles away. I am so disappointed in this radio. Even a cheap transistor radio I've had since 1967 does better.

      The Qodosen SR-286 normally shines on AM/MW, especially with a decent external antenna plugged-in. It might be, that in your case, the switchable antenna amp is turned off.
