Finally got all my stuff in. Plugged it in to my old Acer aspire one netbook and
Apparently the processor is too slow. Audio is choppy as hell and cpu is running 80 to 90% Plugged it in to the big box in the living room and it runs fine. Still need to figure out the Ham it up thing and get a decent antenna made. Right now I just have it hooked up to an old CB antenna and can't get much. I picked up a couple conversations on CB frequencies and can get Fm broadcast. Is there anything less resource consuming than SDRsharp to try on my netbook? What would be a decent, cheap antenna to make for listening to HF? |

I just started making a discone antenna. The low freq is set at 150 Mhz. The bottom hoop is ~22" in diam, and the total height will be ~19". It will probably be mounted 20 feet or so above the ground. There is a big hill behind my place that will pretty much block ADS-B from aircraft to the south, but most local traffic (as well as the airport) is to the north. I won't bother trying the radio out until the antenna is up.

Ordered the same box and hf upconverter yesterday from nooelec 
That to said alI I seem to pic up in m my location with the chintzy antenna is a few fm broadcast stations... Not getting anything on VHF. And my Lenovo net pad lacks the horsepower to run this :-( CPU usage was at or near close to 100% most of the time with just the dongle and running sdr#...mucho broke up reception regardless of how I tried to configure sdr# You won't get much of anything on the stock antenna. I have mine connected to either a 32 ft hf vertical or a log periodic on the roof for vhf/uhf. Once you get a decent antenna it really comes alive. I've been listening to guys in Australia on 20 meters all morning plus some shortwave news from there. Also, are you calibrating the tuning? In order to calibrate I need a constant decent signal....don't really have that yet....will probably go with a random long wire and then a discone Use a weather freq on 162 vhf and zoom in. Center the carrier on it and you are good to go. |

Maybe all the crap running in the back ground of windows machines is part of the problem Did a quick search for "sdr dongle raspberry pi" and found a couple links talking about using the Pi as a server to feed to raw data to a pc to be processed. Do you have a link to somebody using the Pi to do the processsing? If the Pi can handle it then my netbook should as well. I have Peppermint Linux on there but the only SDR package they had in the repository would not install and I didn't have time to look for something else but I'm not opposed to loading a different distro if it'll get this thing working. |

I'm looking to build/buy an antenna on the cheap, have a few questions.
I'm not really looking for any specific frequencies, the once I'm interested in the most are 800mhz-900mhz, 140mhz-160 mhz, and probably 120-130mhz that's probably all I'm interested in now, although I'm sure it wont be enough later lol. Which antenna would be the best, I don't having more then one, just trying to keep it cheap. I saw some info on a ground plane http://www.hamuniverse.com/2metergp.html but the radials would only be 3"??? I don't really know shit about radios, but I'm learning, would a ground plane antenna with ~3" radials be able to pickup signals from about 10-15 miles? I just find that hard to believe. |

You guys having reception trouble...
In SDR#, click on "Configure" next to the pulldown with RTL-SDR (USB) or whatever Then, bump up the RF gain (Separate from the AF gain on the main screen) I have mine set to around 29. Anything over 30 gets too noisy. The "AF Gain" on the main screen is like a "volume" knob. The "RF Gain" I'm talking about is the sensitivity setting. Try that and report back. We'll get this thing working for y'all! |
