Re: Will BlackBerry charger work on PL-380?

Gil Stacy
 

I use a BB charger on mine and it works fine. The old Motorola Razr charger works as well. However, make sure the charger plug that fits in the rx is the trapezoidal shape and not the flattened version (micro?) that is used on some cellphones from both BB and Motorola. 73 Gil


Will BlackBerry charger work on PL-380?

Gary Kinsman
 

Hello all,

This has probably been answered before, but can a 5 V, 0.75 A BlackBerry charger with a mini-USB connector be used to charge the PL-380?

Thanks,
Gary

Thank for the linking the interesting article to our group.

I don't see it mentioned, but do you know how many kilograms the super antenna weigh?

Good DX.

I have added a wire to outside. The SW gives 15dB-20dB less signal when NO ferrite is connected.

I do not know how to slove this, as I sometimes listen without on hands ferrite loop .

It sure is considering you can buy a Grundig G8 from Radio Shack for $49 or $39 if you have a $10 off coupon like I had. I use my G8 as an experimental breadboard, and also have a working portable radio in the deal. I can find a lot of ways to spend the $200 I saved.

I've attached a long wire aerial to the whip on my PL-380. It has no benefit to medium or long wave reception. Actually it deteriorated the signal as suggested in Scott's post.

A solution for connecting an external antenna is in John Bryant's article on adding antenna inputs to the Tecsun receivers (in the Files section). It does required some careful surgery.

For those interested in FM DXing with a barefoot ULR, the PL-380 is ideal.

Good DX all.

The Si4735 is the same as an Si4734 with an added RDS/RBDS decoder and optional digital audio output interface. So RF capabilities are identical -- no SSB.

Hello,

in the Juli/August Elektor there is the first part of a DSP-receiver
pbulished with the Silicon Labs IC SI4735. In the classical ultralights from
China are based on the SI4734 chip.

The second part of the article will be published in the September issue of
the magazin.

The receiver is able to work as standalone receiver. Second possiblity is to
go by USB.

And it should be able to be programmed by an experienced user.

A usefull feature ist the ability to use external special antennas as ferrit
rod or sw-special antenna.

The fully tested receiver will be delivered in few weeks.

Have a look on the Elektor website.
