A few months ago, Wes AC5K sent me an email detailing a keying issue he’d notice on my signal during the ARRL DX Contest and kindly offered to let me monitor my own signal as received at his QTH via a phone call.
Kenwood, Heathkit and other manufacturers used to produce “station monitors” for exactly this sort of troubleshooting but who has one today?
Before my schedule coincided with what would be a decent time to call someone on the phone with what could be a lengthy conversation, the idea came to me that I could use WebSDR for the same purpose – at my leisure and without causing any extra effort for anyone else.
Without my recent interest in SDR I doubt the idea would have occurred at all.
It was a simple process to find a station who could copy me on my band of choice, then send a series of “VVV VVV TEST de AE5X” while listening to my own signal, as received 1000 miles away, through the computer’s speakers.
Due to the rapid (less than a second) reception of my own signal via the internet, I found it was easier to program the CW text into the keyer’s memory so I could send it without the annoyance of hearing my own sidetone echoed by the signal I wanted to hear from the computer.
Phone operators could use WebSDR similarly to make adjustments to mic gain and speech processor controls.
