Perhaps we should have an SDR forum on QRZ.com?

    I use it as a panadapter to find signals on SSB and CW so 100 Hz is not a big problem, just a slight readjustment. Will try hooking up to antennas but need to find a @#$ing MXC adapter.

    Thanks Steve. Upper side-band, about 2200 wide.
    Here's the current HF fax schedule from NOAA which has the freqs, time, locations, etc.
    http://www.nws.noaa.gov/os/marine/rfax.pdf

    Software I prefer is SeaTTY, but several others decode HF fax as well. MultiPSK, Sorcerer, and MixW come to mind. I haven't found a fax program that archives faxes as well as SeaTTY. Others require you to be present to save each one, or lose them all on closing the program.

    Hello.

    Cellphones are SDR now.
    I have the "Ham it up" adaptor but really, in a mobile?
    I took and old Micor that was a wreck.
    It can now transmit 10 watts from 24.5 MHz to 5800 MHz, you name the mode.
    I picked the Micor as it is a good stable platform.
    This was a low band cop car radio without TCXO elements.
    To get it on 6 meters with just one channel was about the cost and effort of this project.
    So, depending on what you are doing, a SDR and an old commercial rig may be just the ticket.

    Hello.

    Some cellphones, like the HTC One V, will go down to around 600 MHz and above 3 Ghz.
    With a few mods, they will do around 100 MHz.
    The CDMA handset has been my interest.
    They can do FM, C4FM, AM, and of course, CDMA.
    The big problem is they are designed for cellular service, so the receiver is not that hot and the transmitter is very low power.
    But, if one were equipped with external amps, maintaining the form factor to a degree.
    I am looking at some sort of chassis mod and a case.
    Remember, Cricket Wireless is going GSM, so thousands are going to flood the market.
    One with a cracked screen will be ideal to test the theory out on.
    All of the commands to get pretty much everywhere is on the web.

    Can't change sample rate, greyed out showing 2.4 MSPS.

    If the program is running you wont be able to change the Sample Rate. Open the program but do not push the start button.
