“Mystery Signal” is alive and well

Some of you have been asking if the “Mystery Signal” is still on the air. Yes it is! Here is a recent clip of it mixed with some CODAR. I’m also trying out SDRUNO software for the very first time. Recorded on May 24, 2017 around 0445 UTC using my SDR PLAY RSP1 attached to my OCF dipole at 35′.

A Realistic DX-300 back from the dead!

This video is a bit different from my others. It is of a vintage Realistic DX-300 shortwave receiver, which was brought back from the dead. I had to replace the AC line cord, put in a new electrolytic filter capacitor and also replaced the burned out bulbs with white LEDs. This is a short video of it in operation. These receivers were from the late 1970s into the early 1980s and featured Wadley loop design.
