Could be...it's weak; not much above the noise floor at S6

General Radio Discussion / Tones on 14105 LSB 1813Z
« on: March 03, 2013, 1813 UTC »
Was trying to find some packet HF to decode, and instead of hearing (or seeing) two distinct tones I keep getting a rapid series of rapid tones spanning about 1300 Hz.  The sequence starts with a second or so of a 500 Hz tone, then the rapid series of quick tones.

+1 on the antenna.  There are a ton of radio hardware options ranging from under $100 to the sky is the limit, but none are very good without a good  antenna (preferably external) of some sort.  Do some research here and related sites to figure out what kind of antenna might work for you; even if you're in a high rise apartment there are options. 

Once you figure out what kind of antenna will work, then start thinking about receivers.  There's nothing worse than getting a new radio, turning it on, and getting squat  ::)

In the meantime, search around for receivers on the internet you can play around with.  That'll give you a feeling for the kind of stuff you'll be hearing.

How much HD space does a night of recording with the sdr-iq take up?

Years of research in dusty library stacks and damp basements has revealed this:

SDR - Software Defined Radio / Re: NooElec brand RTL-SDR dongle

The lower frequency cutoff on the dongles is usually around 60MHz or so.  However....lookee what I found:

And it even looks achievable by my (questionable) soldiering skills.

SDR - Software Defined Radio / Raspberry Pi, antennas, and SDR
« on: February 14, 2013, 0231 UTC »
So now that you can pretty much have a complete computer for $35 or so, and add on a SDR for another $15....thoughts on how this might be fun?  Since you could have a $50 receiver right at your antenna, would it be easier to build arrays since you wouldn't have to worry about losses in the feed (just about running the ethernet cables between the boxes...)?

Haven't tried hdsdr yet, still trying to get gnuradio up and running.

Earlier today I tried to log in with tapatalk for iOS and received an error that access from tapatalk was restricted or that the forum plugin wasn't functioning.  Has anyone else had a problem with tapatalk lately?

The quicksilver SDR QS1R looks very nice, but I can't justify the cost right now.  A sub $50 dongle would be great to play with, but I don't think they'll perform on the SW bands I want.

North American Shortwave Pirate / SSTV or FAX 6925u 0146Z
« on: July 07, 2008, 0152 UTC »
Sounds like SSTV(?) or FAX.  Fades in and out.

If it _is_ SSTV, is there anyway to tell what mode?

Are you experiencing a lot of noise on 6925?
