Check Your Signal On The Internet!

Here's a great example of why I love amateur radio -- hams helping their fellow hams!  If you don't have a close amateur radio friend who lives across the country, wouldn't it be nice to have a distant station give you a reception report, so that you can monitor your signal strength or make adjustments to your mic gain or antenna system?  Let's say you own an older "vintage" rig, like the Yaesu FT-101B, with analog tuning.  Wouldn't you like to check your dial's frequency calibration?  Well, thanks to hams with SDR (software-defined radio) websites, you now can!  All the popular HF, VHF, and UHF bands are covered, so you can easily check out all your rigs!  Here are two of my favorites SDR websites:


WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible for all listeners to tune independently, and thus listen to different signals.  This is in contrast to the many classical receivers that are already available via the internet.  WebSDR is located at

More background information is available HERE and frequently asked questions are answered HERE. Questions and comments can be sent to PA3FWM, the author of the WebSDR software and maintainer of this website.

TECH NOTE: When using your laptop computer next to your ham rig, plug headphones into the audio-out jack of the computer (to hear your own transmission) and a dummy plug into the rig's headphone jack to mute the rig's audio, in order to prevent feedback.  Enjoy!

  4. What is this? "access denied"? This is not public? Or what "public" means to those guys.
    What aboot discrimination some of us feel? Ha?
    Very unfair for the ham radio community, which is WORLD WIDE! It has no boundaries and that's the beauty of this hobby. But it seems not so for the people.
    Very disappointed ham here. I would have just one request to them, besides "access denied", please show at least very little ham spirit and add some sort of explanation.

  6. A question:

    These remote, Internet-accessible sites are fine for checking signal strength.

    . . . But are their receivers
    . . . correctly calibrated as frequency references?

    Thanks --
