Awesome review - should include this in a dxer.ca review... 73

The DSP filtering selections (6, 4, 3, 2 and 1 kHz) also mimic the Si4734 DSP chip, making it seem likely that the new "Skywave" is powered by a Silicon Labs' chip that deletes Longwave coverage in favor of the Airband, and solves the heterodyne issue as well. As for the presence or absence of the dubious "soft mute" function in the Skywave model, my initial impression is that that bogus function has been ditched as well. > > So what are the weak points of the new "Skywave" model?

Whereas the Tecsun DSP Ultralights seem to be designed to feature as many of the Si4734 chip functions as possible, the "Skywave" strips down these functions to the bare minimum. There is no display of RSSI, S/N, temperature or volume level. There is a very basic bar display of signal strength, but that is it. Be thankful for the rotary volume control, though-- although it doesn't light up the display or show you its level when changed, it is a major functional improvement over the clunky up/ down volume buttons on the C.Crane SWP. > > More details, complete disassembly and a full review will be forthcoming. > > 73 and Good DX, > Gary DeBock (in Puyallup, WA, USA ) > > > _______________________________________________ > IRCA mailing list > [email protected] > http://montreal.kotalampi.com/mailman/listinfo/irca > > Opinions expressed in messages on this mailing list are those of the original > contributors and do not necessarily reflect the opinion of the IRCA, its > editors, publishing staff, or officers > > For more information: http://www.ircaonline.org > > To Post a message: [email protected] > _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
