Anodic robust aluminum case doesn\u2019t conduct electricity, which prevents from possible shorts if bared wire hits the case. This device has a built-in protection from polarity reversal. Mounted Jack 6,3 mm connectors possess qualitative electric contact, a factor which makes lower quadrature disbalance. High-speed USB 2.0 interface is used for transceiver\u2019s control.<\/p>\n<p style=\"text-align: justify;\">SunSDR electronic part is executed on one two-layer PCB. Due to this engineering solution the device has certain advantages: greater reliability, small enclosure dimensions and weight. The amount of digital lines on a PCB were reduced because of mounting on the card CPLD. Therefore it makes lower the level of noise pickups from digital chains (because now they are placed inside CPLD crystal). It should be also noted a low level of the carrier frequency transmitter (lower than -55 dB), reached by right component layout of mixer and transmitting tract topology. Band LPFs (low-pass filter) are executed on a ceramic chip coils. Using such technology allows to make lower the level of intermodulation distortion transceiving tract and makes higher a receiving dynamic range.<\/p>\n<p style=\"text-align: justify;\">Receiver has 5 gain levels, which are switched from the program ExpertSDR. Each gain level defines receiver\u2019s sensitivity. Receiver\u2019s measurements with the soundcard M-AUDIO \u2013 Audiophile 192 are shown in tables 2 and 3.<\/p>\n<p><a href=\"https:\/\/www.cqdx.ru\/ham\/new-equipment\/sunsdr-transceiver\/attachment\/screen-shot-2011-09-15-at-6-46-23-pm\/\" rel=\"attachment wp-att-26860\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-26860\" title=\"Screen Shot 2011-09-15 at 6.46.23 PM\" src=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2011\/09\/Screen-Shot-2011-09-15-at-6.46.23-PM.jpg\" alt=\"\" width=\"686\" height=\"464\" srcset=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2011\/09\/Screen-Shot-2011-09-15-at-6.46.23-PM.jpg 686w, https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2011\/09\/Screen-Shot-2011-09-15-at-6.46.23-PM-300x203.jpg 300w\" sizes=\"auto, (max-width: 686px) 100vw, 686px\" \/><\/a><\/p>\n<p>PDF file: <a href=\"http:\/\/sunsdr.com\/en\/products\/download\/16-transiver-sunsdr\/8\/SunSDR_UserManual.pdf.html\"><span style=\"color: #0000ff;\"> SunSDR User Manual<\/span> (Russian)<\/a><br \/>\nTransceiver SunSDR-30W(sound card inside) 25 990 rub.
