    I have an MLA-30 with a green LED. I bought it about a year ago, or so. I now have an MLA-30+ as well.

    Is there much difference between the MLA-30+, the K-180WLA and the AMLA150 ?

    Is it time for a Comparison/Shootout of the MLA's and their variants?

    Thanks for this comparison. I have the 30+ setup indoors in my attic, and I think it works pretty well. Seems to do better than the long wire I have strung up (in the attic as well). Looking for any easy tweaks to make it even better. Is it possible to replace the bias-tee box altogether with a less noisy one?

    My MLA-30 (I.e., not plus) has a green light as well) and has very good reception. I wish lol have to try the higher frequencies on shortwave in order to test the reception. Medium wave has very good reception however, so maybe these were manufactured without the + indicator on them.

    Great vid. Subbed! What cable do I need to go from the MLA 30 amp to a 3.5mm input? I have an Eton Excutive Elite receiver. I can find anything online. Also, I'm not sure if it's supposed to be mono or stereo? Thanks.

    Thanks for the video! I bought an mla30+ but i notice no difference when the power to it is on or off. Should you see a signal increase when turning power on? Or is it normal there is no difference? Thanks!

    • @OfficialSWLchannel
      @OfficialSWLchannel  8 หลายเดือนก่อน

      there should be a big increase, make sure the power is correctly applied to the Bias T and that the wire going to the antenna is not damaged as it powers the amplifier in the box of the loop.

    Until everyone sells out of the mla-30, sellers won’t be advertising the mla-30+ because nobody will want to buy the old ones now that they know there’s a difference. :)

    You are right! The description on Amazon does not have + in it anywhere but the pictures show 30+. I ordered one for my RSPdx and Tecsun PL-330. I am curious why the PL-330 MW doesn't connect to the external antenna??? Just the internal antenna only.

    • @OfficialSWLchannel

    I wonder if the internals of the MLA-30 and MLA-30+ are the same but merely the gain setting is tweaked a bit to increase the signal receiving sensitivity at the 15,100 KHz (19 meter) as you had shown in your MLA-30 & MLA-30+ comparison vid? As you have stated, this might make for a good vid with you opening both versions for inspection & demonstration. TH-cam poster kurama10goo has kindly detailed how to adjust the gain adjustment here: th-cam.com/video/f7XhuN27daU/w-d-xo.html

    I AM A BIT CONFUSED by the voltage differences listed on the two white boxes. The smaller box reads 5 volts at the USB input and the loop attachment box reads 12 volts and there is no input! My QUESTION is: Do I have to somehow make two different connections to the antenna system or do I just slam 12 volts into the 5 volt USB port on the small white box? Thanks and take care

    • @sandyx4522
      @sandyx4522 3 ปีที่แล้ว +2

      Don't slam 12v into 5v port! There's an internal voltage booster inside the BiasT to generate 12v from 5v input for the loop.

    I'm so confused and heartbroken. I bought one that says "MLA-30+ Plus", it has a much larger loop and it says lower range is 0.1Mhz which doesnt match anyone elses. I have no idea what I got and I feel ripped off.

      @@OfficialSWLchannel Not the one I got, mate. I got sent something real weird... there's only one review for this one. I think it's some kind of knockoff but there are subtle differences. The loop is almost 2x as big, it's al branded "MLA-30+" but instead of being 0.5Mhz-30Mhz like the plus, it's listed as 0.1-3. I think this vendor took an old MLA-30 (non-plus), printed a new label, and gave it a bigger steel loop.

    Do you think they added a small bandstop filter to weed out 1-5khz range? Would that do enough to help lower the noise floor? Thank you for all your help, Gilles!!
