Ron’s thoughts on RFL200 and Q-Stick longwave antennas

Many thanks to SWLing Post contributor, Ron, who shares his thoughts on comparing two portable longwave antennas:

To begin, for reference, check out this post where The Professor reviews the RFA200. Also, check out the following video from the replies of that post:

Both the RFL-200 and the Q-Stick came in today.

Performance of both was very nearly identical but for now the Q-Stick wins on price ($67.50 vs. $75.78 delivered) and the Q-Stick does both LW and MW.

But Gerry says he’s going to close RadioPlus early next year so-presumably-
that will leave just the RFL-200 and its REA-200 sibling.

The “200” no doubt comes from the length, 200mm or 8 inches…the Q-stick
uses a 7-3/4 inch ferrite bar which is probably why the similar performance.

There is one thing: the small tuning knob is not hard to turn on the RFL-200
as it was on the REA-200 tested earlier but a bigger knob would be nice.

But the tuning cap uses a 1/8th inch shaft so finding a larger knob is too
much bother, most are for 1/4 inch shafts.

By comparison the Q-Stick has a nice big knob and is quite easy to tune.

So for now the Q-Stick would be the better buy, but don’t tarry.

[One more note,] if you want the most bang for your buck, forget both of these, get
a PK Loop
for $90.60 delivered (be sure to specify the 155-500 kHz model).

Thanks for sharing your thoughts, Ron!

The XHDATA D-808 and longwave: how to build an effective antenna

Many thanks to SWLing Post contributor, Mad Radio DXer, who writes:

I said I would share my results for attempting to receive LW signals on the XHDATA D-808, & if I can use a longwire to improve reception on this radio. This was after posting videos when I used around 50 metres of longwire connected to the D-808 for improved Medium Wave reception & to prove it works.

This first video shows that it is not possible for LW, no matter if I connect the 50 metres longwire to the 3.5mm input or the whip antenna. I also compare reception of the same station with the Degen DE1103 PLL using the 3.5mm input. The Degen DE1103 still had better reception even when I used the whip antenna extended at the very minimum when using the LW/MW external antenna trick. I know I should have used the internal ferrite antenna of the Degen compared to the D-808, but in any case I did try off camera & reception was about the same. So unfortunately the D-808 was never going to win this round.

However, there is a solution.

The answer? Build yourself a Long Wave induction antenna as shown in the second video [below]. I made one some time ago, as I grew frustrated at how poor the Tecsun radios were on this part of the band & that there were no LW induction antennas available to buy. I tried a signal on 207 kHz which is RÚV Rás 2 from Iceland. Either a radio with a very good internal antenna or a good external antenna is needed to receive this station at my QTH in southern England.

Placing the D-808 on the induction antenna resulted in a very pleasing result, which was it did get reception of Iceland on 207 kHz. So this shows that it is possible to DX on the LW bands with the D-808 with some “external help”.

For anyone interested making a LW induction antenna as shown above, here is a link to a video that has basic instructions & further results. It may be a very simple build & finish what I did, but for me the most important thing is that it works.

I hope my comments & videos will be a great help to all. Happy DXing.

Regards,

Mad Radio DXer.

Excellent–your comments and videos are most welcome! There are quite a number of SWLing Post readers who are avid longwave DXers. I love the simplicity and efficacy of your longwave antenna–something anyone could build.  A clever upgrade to the affordable D-808. Thank you for sharing!
