  3. Good Ole Boys Radio Net- 40 meters

    40 meter amateur radio recording of the Good Ole Boys net on 7.279 from January 30, 2014.

    Recording will demonstrate the receive audio on this band. Make note of the location of each person (call sign and city) checking into the net. The recording was done by W1XWX located about 45 miles East of Dallas, Texas, using a Flex 3000 SDR radio.

  6. Dstar digital ham radio audio

    TelescopeMan records a Dstar QSO between several ham radio operators in Wisconsin, and also a QSO with some local Texas hams in Keller, Texas and Beaumont, Texas.

    Notice the clarity of the digital audio transmission and the dead silence between transmissions.

    73 and clear skies, TelescopeMan

  7. Flex 3000 Sound Recording December 2013

    TelescopeMan records the Flex 3000 SDR (Amateur Radio) while dialing around the 20 meter radio band. At the 5:30 mark you can also hear various digital signals along with CW signals.

    One of the last digital signals is slow scan TV — someone transmitting a picture. All of the digital signals can be decoded using the appropriate software such a FLdigi and Ham Radio Deluxe.

    TelescopeMan continues to be amazed at the capabilities of the Flex 3000 SDR radio. It’s simply unbelievable the weak signals it can receive and the quality of the software filters.

  10. Route 66 Ham Radio Contacts

    TelescopeMan records several of the Route 66 ham radio contacts- W6P station. These were on 40 meters and show the Flex 3000 radio receiving quality. Usually if you can hear them they can hear you —— maybe! :)
