    Youloop antenna repair

    The used youloop I picked up has a damaged SMA connector on one of the loop branches and the feed line. Can I just shorten the bad branch, reterminate it and then repeat on the other branch to match the shortened length? How closely do the lengths have to match? I'm assuming I can just shorten...

    System requirements for 8 SDRs fed into SDRTrunk

    I’m in the process of researching moving my feeds from simple scanners to using SDRs. I know 8 is likely overkill but I have a 8 port multi coupler so I figured why not fill them with SDRs considering they are cheap. Everything will be mostly analog, with some P25 conventional (all public safety...

    Want to get into shortwave radio

    Sorry for the vague title. I want to get into shortwave radio, but I am not sure where to start really. I found my interest in it through North Korea, they have a broadcast called Voice of Korea as most of you might know, and that's how I found out about shortwave. Had no idea this medium...

    I found an old RadioShack "Pro-97" while tossing junk out and had an extra antenna suitable-ish for CB, and had a moment of curious inspiration about some of the more incessant yappers I've been hearing lately. There's been some conversations here about whether or not some of these jackwagons...
