I want to bring to the attention of your readers & fellow XHDATA D-808 owners that it can accept an external antenna on MW without the need for any modifications. This I found out during a DXpedition to the field when I used around 50 metres of longwire.
I have some videos to prove this. The first is the difference between the external longwire antenna vs the internal ferrite antenna…

The second video is pretty much the same as the first, but this time I am tuning on a lower frequency of the MW band. Also I show that not only can the 3.5mm antenna input be used to connect an external MW antenna, but the internal whip antenna too.

The third video shows the difference between the XHDATA D-808 vs the Degen DE1103 PLL (using the external MW antenna trick). when using an external antenna for Medium Wave. In my opinion there is not much difference between them reception-wise, but the D-808 has the advantage of being able to select tighter bandwidth filters for less QRM from stations on adjacent frequencies.

These days I am more of a MW DXer than on shortwave. I am thrilled to have found out that the XHDATA D-808 can accept an external antenna for Medium Wave in stock form, since my understanding when I read some reviews was that it could not unless an internal modification was done. I will do more experiments of MW reception with the D-808 on my next DXpedition.

I want to add a few more points…

• The D-808 does not work with an external longwire antenna for Long Wave. I tried this & will upload a video of the result soon. However, I tried using my LW induction antenna at home & it did get stations which it could not using the internal ferrite antenna on its own. Again a video of that will be upcoming.
• I tried using a Wellbrook antenna for improved MW reception on the D-808 & unfortunately it does not work well. There was too much background noise, & there were harmonics + images all over the band. I would instead recommend using a good passive antenna like a longwire rahter than a strong active one.
• It is recommended to use 25 metres or more longwire for best results. Obviously, the more longwire used means the lower the frequency gain for reception.
• I cannot guarantee that this will work for all XHDATA D-808 units in case, for eg, some have different firmware versions. All I can say is it does not hurt to try, but bear in mind what I said about the longwire antenna length. Also a nice quiet location away from manmade noise helps even more to minimise any QRM.

I hope this has been helpful & useful to all XHDATA D-808 who like me, are really into MW DXing.

I’m happy to hear that you’re enjoying MW DXing and that the XHDATA D-808 is serving you well! Over the years, my DXing habits shift and change, but I’ve always included a healthy amount of mediumwave DXing in the mix. Especially when propagation on HF is dismal, I head down to the MW band for some action! Thanks again for sharing your videos and tip!
