Johnny,

Any loggings or information concerning non-Ultralight live DXing portables is welcome on this site. I am the Owner/ Moderator of the group, so I should know :-)

My recent 2021 Ultralight Radio Shootout article included 7 pages on the non-Ultralight XHDATA D-808 model, and I have used that model (as well as the CC Skywave) during all my ocean cliff DXpeditions for the past two years. Do I lose any sleep because the model isn't an "official" Ultralight? No.

"Official" Ultralight status is relevant only to the Awards and DXing Records programs, both of which have been in limo for years because of a lack of volunteers. Use whatever portable you feel comfortable with, and enjoy live DXing (and life) any way you wish.

Non-Ultralight Radios?

Hi all,

What would be a good group recommendation for discussion and loggings related to those radios that would not be considered Ultralight?

Thanks for the tip, I don't want to post non-ultralight information here of course.

Hi AF7KR (vbifyz) and group,

I just bought the Koss Titanium headphones mentioned and REALLY like them!

Lightweight and good sound with a good price point.

Thanks!

Gary, did you ever give any thought to going to a small custom fab shop and getting a quote on a small quantity build of your small design FSL? These kinds of shops specialize in small run custom production. I suspect you would have no problem selling them!

Thanks Tony,

Your suggestion is appreciated, but construction of an FSL requires a lot of diverse skills like PVC pipe gluing, Litz wire coil wrapping and high wattage soldering, not to mention the superglue-stabilized ferrite assemblies and waterproofed variable cap. The supply chain for the components is also pretty convoluted, including Russian surplus ferrite rods from the Ukraine, Litz wire from China and the variable cap from the USA. The tricky supply chain, painstaking construction and high cost components have probably all contributed to the rarity and high demand for the antennas.

Hola Jorge,
The PL-398MP and PL-398BT, along with the older PL-390 are identical electronically. The closest to a single speaker version is probably the PL-310.

Hi Peter,
Is there any noticeable receiving differences in between PL-398MP and BT models? Is there a PL-398 with just one speaker?

Best distance for an ultralight at my present location.
Obviously better on the Tecsun PL-398MP.
Both radios used "barefoot" (just their internal ferrite rods).

The online distance calculator was wrong thanks to Noel for alerting me. 10960km is correct

Re: 96.3 OFM 209km D-808 with yagi aerial

Jorge Garzón
 

Yes, that's the way Phillips! 
Peter, it's a pity that these TECSUN little ones does not offer RDS decoding!! 


Re: 96.3 OFM 209km D-808 with yagi aerial

Phillips
 

Yagi's offer antenna gain but they also have the benefit of directionality.

Verticals (whip)s are omnidirectional) and offer no opportunity to null out.  Dipoles have a figure-eight pattern and have two opportunities per rotation for nulling.  Yagi's have a cardioid pattern and so are unidirectional giving the best opportunity for nulling.

If anyone is having trouble with pest stations on or near the frequency of interest, a yagi might be the solution depending on the relative directions of the two stations. 

If the yagi overloads the Rx, an attenuator is a simple construction.

Hi Peter, 
Could you provide more info about that use of a yagi with the little D-808, and your overall opinion of the results? 
Gracias

The PL-398MP is much better on FM than the XHDATA-D808.
The D-808 wasn't able to pass this test when using a vertical FM dipole.

FM stations 100kHz apart can be separated. 96.2 Gabz FM Gaborone/ Gabane Botswana 69km 96.3 OFM Schweizer-Reneke South Africa 209km

Hola Jorge,
There is an antenna socket on the left-hand side of the D-808 which works on SW and FM.
There is some evidence of overload using a yagi on FM. I'd imagine the overload will be worse in Spain.
An outdoor FM dipole might be a better choice.

The D-808 has poor selectivity on FM when compared to Tecsun DSP portables. The D-808 also has several birdies on FM.
RDS on the D-808 only works on strong signals. The audio in my video was good but no RDS was decoded.

Thanks Peter,

After Paul Walker's DX-ploits in Alaska the demand for compact FSL's has gone off the charts, but I appreciate your interest, and will put you on the waiting list.
