My Toshiba Netbook NB505 has one better than a stereo microphone input. It has a stereo line in option. I have max'ed it out on main memory - 2G SD RAM - but the Atom processor may not have enough

Hello All, The recent Ultralight DXpedition to Lincoln City, Oregon featured pretty bizarre South Pacific propagation, with each bad day being followed by a good day, and vice versa. This propagation

Hello Jerry, Congratulations-- you seem to be the only other person so far who has made a serious effort to construct one of these plastic 7.5" loopstick frames to glue to the top front cabinet

Gary, or others, just finished cutting the 48 inch level to 8 inches on top and 5 inches on bottom for mounting the 7.5 inch Ferrite Bar. After cuttingthe width of the Bottom edge to make it even

I would like to apologize to the list for any problems relating to my questioning of ULR standards. As we have learned from the posts concerning iPhone SDR apps, what was cutting edge technology 3

Notebook computers suffer from the same problem as cell phones: you've got to find one that offers stereo microphone input. Too often notebooks skimp on the sound card, and offer only a mono

Even the best iThingy will struggle with "garbage in", so it makes sense that the frontend has to perform - and that an ulrx could serve well. Thanks for this additional info, Charles. It will be

I have never had a problem since installing trendmicros (free) RUBotted. Michael UK

He said a spambot got into his machine and sent out 700 mails in a short time and he apologized for the problem. Powell NNNN POP email is powell at backroads DOT net

One more comment on this thread... The iSDR iPhone app utilizes the same digital signal processing techniques found in PC-based SDR receivers. It does frequency domain filtering using a theoretical

A variety of used, professional & prosumer grade digital recorders are on the market now, too. I've seen models by Edirol (Roland) and Zoom for auction and Buy-It-Now on Ebay, and there's a regular

Thanks Powell - I assumed that was the case. I've deleted the messages, and will keep his account active assuming he gets it sorted out. Kevin S Moderator

Hello Michael, Unfortunately I'm not familiar with the DSP uldx, so I can't provide an informed comparison. I have built resonant ferrite loop antennas for 3.5 MHz band, including the one pictured on

Hello All, Despite modest expectations the mid-summer LW propagation had some pleasant surprises this weekend, although DXers probably needed to sacrifice some serious sleep to take advantage of

Todd's machine is infected. So do not open any of these he has sent out. Powell NNNN POP email is powell at backroads DOT net

Hello All, Like Steve, I was able to track down two all-time new Ultralight beacons during the Ndblist "Barn Door" CLE-145 event (although neither one is as exotic as Steve's 400-ENS in Mexico,

Hi Jerry, My own audio recorder (which comes with MP3 conversion software) is the Sony ICD-SX57, a very compact model which can record about 3 hours of high quality stereo (if desired) in its flash

Thanks for your informed input, Charles. Very helpful. Can you suggest links to diy RF frontend designs? What aerial and frontend configuration is necessary for the iPhone DSP to equal a DSP uldx

I meant to mention one more thing: regarding SDR on other devices, like Android, Webos, QNX, Symbian, etc. The main thing preventing SDR on those devices is the lack of stereo microphone input. Note:

By purchasing a used or refurbished iPod touch, and building the RF front-end yourself, you MIGHT be able to set yourself up with an SDR receiver using iSDR for under $100. You can also get an iPhone
