Re: Radiwow R-108 and XHDATA D-808 Loopsticks

Hi Max,

<<<   Is the section of the ferrite rod rectangular mm 8x4 or round Radius 8 with to flatten sides?   >>>

The R-108 loopstick's ferrite rod is completely rectangular, with the flat (8mm wide side) facing up. A detailed photo of the loopstick installed in the R-108's RF board is attached with this message.

<<<    I have found this https://www.aliexpress.com/item/Tangda-soft-ferrite-rectangle-plate-core-ni-zn-material-4-8-50mm-magnetic-bar-4-8/32844810654.html

Disregarding the fact that the material could be different, will it work adding one bar at each end of the stock ferrite? They can be hold in position inserting everything inside a 8mm pvc tube and leaving out just the coil.   >>>

As you can see in the photo below, there is no space inside the R-108 cabinet to add anything to the loopstick. A small circuit board with the external antenna plug-in jack is to the left of the loopstick, and the tuning control encoder (on the digital board) takes up the space to the right of the loopstick. External loopstick mounting would provide more space, but in my opinion if you are going to go through the hassle of external loopstick mounting you should probably go all the way and perform a "Supercharging" operation with a much larger ferrite rod, 250/46 Litz wire and a matched-size loopstick frame. The 'Supercharged" D-108 works like a dream-- it's lightweight, compact, and has no digital defects like the PL-380 and other Tecsun Ultralight models.
