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

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!
