$ 37 SDR?  View Printable Version 
Sunday, April 30 2017

Dave:


Those units are very basic, beginner models that are not for serious DXing. They use chips from low cost cable tuners.

I'd move up a level if I were you.

One low cost option will shortly be released: http://airspy.com/airspy-hf-plus/

No price yet, but I suppose the price won;t be much different than the existing VHF and UHF models that go for about $ 160.

$ 37 SDR?  View Printable Version

I may never be able to afford a Perseus but I have noticed that SDR prices
have been dropping. On a whim, I searched "SDR" on a few international,
online retailers.

I found a $ 29 one, at TomTop but it was in kit form. :(

I searched again and found this one, for $ 37. Complete, ready to go. 100
KHz-1.7 GHz

http://www.tomtop.com/communication-instruments-200/p-e2225.html

Would this have any chance of being usable for MW DX? My main question is
how much of the spectrum could be recorded? FM DX?

Now, if they only offered a $ 37, Wellbrook knockoff. :)

73,
Dave in Indy

Craig Barnes' TP-DXpedition to Princeville, Kauai, Hawaii (Part One)  View Printable Version 
Saturday, April 29 2017

IRCA


549 is a straits-area dialect (Fujian, Guangdong area). Very likely CNR-5.

603 Neither of these is KBS Happy FM in Hwaseong (Korea). There is a lot of
noise, so I can only say that much. You're dealing with a Chinese station
here. Likely CRI in Hainan, but could also be RTI. I'm unsure if RTI is
still on the air on 603. Their other station at this site was knocked off
permanently from typhoon damage. But absolutely NOT Hwaseong.

657 Yes, this is Pyongyang.

693 This is Portuguese and it's Brazilian Portuguese. My cousin in Brazil
confirmed this fact, but no more specific than that.

765 CNR-5 news jingle (if you could call it that) is heard

783 Yes, same. Taiwanese dialect.
