  • Extra antenna isolation when the receiver is powered down

This has a revised RF front end using a high linearity NXP RF bipolar amplifier, an IQ audio output to feed external sound cards and other revisions to improve RF performance, gain distribution, IQ balance and the SDR display.

September 2013...As a result of development work on the CCW Sentry SDR transceiver the frequency range of the SDR-4+ has been extended to cover the 4m amateur band. The frequency coverage is now 0.85 to 70.5 MHz. This new version also includes a revised USB sound card and a new antenna isolation transformer with a 2 kV working voltage rating without the 450 ohm antenna input.

January 2016...As a result of further development work on the new CCW Sentry SDR transceiver the RF amplifier has been changed to a high linearity NXP RF bipolar device. The receiver IP3 measurement is now +15 dBm measured with two -2 dBm carriers 200 kHz apart at 14 MHz.

This is a link to our CloudMe folder allowing the files included on the CD shipped with each receiver to be downloaded here 3.

The SDR program we recommend for first time users of SDR receivers is HDSDR which can be downloaded here 4.
