1  eHam Forums / SWL (Shortwave Listening) / RE: Portable MW/FW receiver suggestions? on: November 16, 2012, 02:38:35 PM
I own a number of portables, Grundig G6, Sangean 909, Sony 7600, Tecsun 660....

For my money the prince of portables is the Tecsun PL-390.... about $60 delivered ex Hong Kong and Ebay ( Anon-co are good).

It only covers broadcast bands so no SSB or utility stuff,

however ..

It has 'ETM' ( easy tuning method ), select the band of interest, press ETM and it will scan and store any station it finds.

It can be recharged via the USB port on your computer

It has 'Line In' and can be used as stereo speakers for your ipod or similar.

On SW great for just doing a quick scan a few times a day to see what bands are open.

I haven't bought the company but  I like them so much  I have bought three of them. One for home, one for my boat and one as a gift.

 
2  eHam Forums / Computers And Software / RE: Powering a MacBook Pro w/12 Volts w/o an Inverter on: June 20, 2011, 04:32:48 AM
Looks like I'm a day late and a dollar short yet again but here goes.

I bought one of those for use afloat with a Macbook. I found it very noisy to such an extent that I had to unplug it to hear virtually any HF at all.

I have replaced it with a  Mini-box DCDC-USB http://www.mini-box.com/DCDC-USB which I have mounted in the enclosure they sell for it. No noise from it at all.

It was a simple matter to adjust the output voltage to the required 16.5 volts using the supplied software running on the VMware Fusion/ Windows side of my Mac.

Only issue was that I had to use the cable from the Hypermac charger to get into the Magsafe socket on the Mac.

I also use a couple of the mini-box 12v-12v power supplies on my Via computer and my LCD screen so as to avoid  all the RFI issues that go with using an inverter.

Hope this helps,
