    This has come up previously, our licence is issued in the UK so M0xxx and we use the appropriate regional prefix for where we live so it’s correct.

    I discovered there was an issue where users below the level of Admin didn’t see the ‘upload an avatar’ dialog.
    I traced this to a setting not ticked allowing everyone to upload.

    You should now be able to see the option to upload your own avatar on your profile screen.

    User avatars are back.
    I’ve installed a new plugin which allows you to upload an image from your own PC (less than 150px) to use as a site avatar if you don’t want to use the gravatar.com system.

    Enjoy, but if this plugin proves to affect other parts of the site it may get withdrawn.

    To use it, display your own profile and scroll down to the Avatar section, here you get the choice of a using Gravatar.com or uploading your own image

    Congratulations to everyone who passed the exam.

    Don’t know if I like the term ‘failed’, I prefer to think of it as ‘didn’t pass’, less of a negative connotation.
    Better luck next time guys!

    I’m sorry, I’ve had to withdraw the facility to upload user avatars as the plugin is interfering with the forum.

    You should create an account with gravatar.com using the same email you have registered here and upload your image there, wordpress will pull the image through here automatically.

    I had similar problems to Bob with my home hub disconnecting with 100w on 80m.
    I now have a 4th gen hub and have relocated it to another room so it will be interesting to see if it holds up.

    I never did take the time work out if my signal was interfering with the hub or if it was simply wiping out a chuck of the bandwidth the broadband was using causing the hub to disconnect.
    I’m a fair distance from the exchange so noise in the cable may be a contributing factor leaving me with bandwidth slots around 3.5MHz which get noisy while I’m transmitting.

    anyway, happy to join in when time permits

    If you want to include photo’s, use Geoff’s method, upload them to Photobucket and copy the direct links into the post, the forum will take care of resizing etc.

    ps I’ve changed the post owner to be Scott so he can edit it.

    Further to Cambell’s note, I’ve reinstated manual approval of new users so there’s no automatic path to register and spam the forums.
    All new registrations will be held in a queue until approved by an admin.
    supplementary information to support a registration (no callsign yet but undergoing training etc.) can be emailed to webmaster@cpsarc.com.

    This introduces a delay into registering for the site but the trade off against spammers and fraudsters is worth it.

    Hi Alex,
    I wouldn’t recommend jumping in to DSTAR, the radios are expensive and there’s not much activity up here.

    If you’re looking for a nice VHF/UHF little hand held to get you started you should look at the BAOFENG UV-5R which many people in the club use.

    These low cost dual band radios from China are an excellent first time purchase from ebay

    We’ve tested these and they are great performers.

    If you ask MM0DXC he’ll program it up for you too with all the UK frequencies.

    I’ll leave the post up as a warning to others

    John MM0JXI

    There is some interaction between the dongle and the cell site to set the output powers, if you’re getting a big signal on receive, the system may turn down the power as it thinks there is a good link.
    If you are only getting 2 bars, the phone will raise its output power as it thinks the link is poor, but that uses more battery

    Also the faster the connection, the better the signal needs to be and so the range of the cell reduces.
    If you could limit the speed of the connection you’d get better range but everything seems to be set up to give max bandwidth. Unfortunately you don’t get to choose speed v range, the system adjusts for a reliable signal.
    Too many errors and the cell will try to hand off to another.

    I think Gordon is in the right area, the transmitted signal from your phone will be much lower when received at the cell site so even though you get a good receive signal the return path isn’t good enough to sustain a connection.
    The theoretical range of a cellsite is about 30 miles but that distance shrinks rapidly with the bandwidth required for a data connection.
    I think what John was seeing was the cellsite handing off to another site based on whatever preprogrammed limitations are set for signal to noise, delay etc.
