The power of the PC also brings graphics, memory, recordings etc.<\/p>\n<h2>Why these four rigs?<\/h2>\n<p>In the beginning, and it was it which led me to be SWL, I acquired the RADIOJET based on its announced characteristics: sensitivity of &#8220;secret services&#8221;, adaptable to all cases with filters, graphics tools&#8211;\u201cStar Wars equipment\u201d is not it! Later I learned about 50 MHz and at the same time I was struggling to exploit the Radiojet SDR.<\/p>\n<p>A good opportunity to purchase an ICOM R75 brought me back to\u00a0conventional radio ergonomics. As time passed, I felt my listening skills improved\u00a0with these 2 receivers and the receiver syndrome\u00a0grew! A Kenwood R5000 joined the others for its VHF potential and HF reputation.<\/p>\n<p>Then I discovered an NRD-525 on Ebay at a fair\u00a0price point (rare)&#8211;it joined the group of receivers. The latter two were sold and replaced respectively by an AOR 7030 and by NRD-535. I really enjoyed the 525, but the 535 is even better.<\/p>\n<p>In use, the RADIOJET and R75 have always posed problems with settings and sound quality. Kenwood reassured me about the fact that we could get some nice reception without fighting against the controls. validated by the AOR, the NRD 525 &amp; 535. Perhaps I did not understand the manipulation of digital filters???<\/p>\n<h2>Now to the shack!<\/h2>\n<p>The four receivers are placed side by side, but arranged so as not to disturb each other (eg. the display of the ND535 disrupted the RADIOJET).<\/p>\n<p>The antenna is a 25m random wire oriented East\/West\u00a0with 9:1 balun and its own ground. The passage from a receiver to the other is done by a conventional antenna switch.<\/p>\n<p>All the tests were performed in one evening for constant conditions, there was a fairly present QRM which, was not too bad for comparison purposes. The tests were made in SSB or AM. Preliminary tests had shown that the results in digital modes (PSK31, JT65, ..) relied more on the decoder performance of the PC rather than the receiver. The tests increased from the lowest frequency detected this evening (Europe 1-163 kHZ) to the highest (Foreign Broadcast =15,545 MHz).<\/p>\n<p>The highest frequencies, up to 30 MHz, were deserted in phone, at least for my installation.<br \/>\nThe procedure was:<\/p>\n<ol>\n<li>Signal\u00a0is detected from the spectrograph SDR: it typically\u00a0&#8220;sees&#8221; almost inaudible signals.<\/li>\n<li>The candidate frequency is tuned\u00a0on all four receivers<\/li>\n<li>I listening to all of the signals on all receivers,\u00a0seeking to get the maximum performance, using all possibilities (notch, passband, IF Shift, integrated amplifiers, attenuator, etc.)<\/li>\n<li>Results are reported in the table below.<\/li>\n<\/ol>\n<p>One can notice rather quickly:<\/p>\n<ul>\n<li>that age is not a handicap<\/li>\n<li>the number of functions is not always an advantage<\/li>\n<\/ul>\n<ul>\n<li><strong>1102S RADIOJET<\/strong><br \/>\nPerformance and capabilities above the rest (on paper) and requires being connected to a PC. At the present time, on an old Celeron 2Gb ram, the RadioJet&#8217;s application never saturated the CPU. The band\u00a0spectrum display\u00a0allows one to find the QSO, to filter theoretically perfectly, but it does not always equate to the understandability of the signal or give a pleasant audio. And the number of software features and functions complicates the signal manipulation. The sound is still a little metallic, perhaps due to the\u00a0signal processing software.\u00a0Its small size makes it a unbeatable mobile receiver for travel, functions are incredibly useful\u00a0for those who master the\u00a0RadioJet application.<\/li>\n<li><strong>AOR AR7030<\/strong><br \/>\nInherently simpler at face value&#8211;the AR7030\u00a0is ultra easy to use. It makes it easy for the user to find and tweak a candidate signal. It&#8217;s intuitive and has essential functions only. It has well-designed electronics. The AR7030 is also best receiver tested for handling strong signals without overloading\u00a0(broadcasts stations or nearby hyper-kilowatted amateur radio operators) which seems to prove that it is designed for\u00a0these stations. Its limit is the lack of adaptive notch filter types to clean the noise, which is still quite present when the QRM is there. (The newer\u00a0version 7030+ has added features to help). Finally, it is the smallest stand-alone, portable and with 3 options of antennas connections.<\/li>\n<li><strong>ICOM R75<\/strong><br \/>\nThe R75\u00a0climbs up the frequency band all the way to 50 MHz, the only receiver tested with this frequency range. It enjoys an excellent reputation, and can be equipped with a DSP (digital signal processing) on audio. The DSP provides adaptive noise reduction and automatic notch, but has a relative effectiveness which is not always successful in clarifying the signal. Sometimes it adds an unpleasant &#8220;rattling&#8221;. In use, the interface is pretty intuitive&#8211;mixing commands by buttons and menus. Twin pass band tuning (PBT)\u00a0is effective and allows for\u00a0IF Shift and\/or notch. The speaker is (very) small and gives an aggressive\/harsh sound. This receiver is relatively small in size and lightweight. It has a mobile stand and is designed for\u00a0a 12-14V power supply.<\/li>\n<li><strong>JRC NRD-535<\/strong><br \/>\nThe NRD-535 is the\u00a0oldest tested&#8211;indeed, it was already discontinued\u00a0before the other receivers were in production.\u00a0A solid and reliable construction, good ergonomic with conventional front panel controls, good sensitivity, and a decent sized speaker have earned it status as a benchmark\u00a0in its time. Very sensitive, it extracts the signals and, once found the right filter, gives it pleasant audio. Some signals are not completely cleaned but it does rarely less than others.\u00a0The NRD-535 is designed for home use:\u00a0it is heavy, almost 10 kg, and is contains\u00a0several circuit boards which\u00a0should not be too exposed to excessive shocks, especially considering they&#8217;re over\u00a020 years old.<\/li>\n<\/ul>\n<h2>Summary<\/h2>\n<p>My ranking is as follows:<\/p>\n<ol>\n<li><strong>JRC NRD-535<\/strong> for its ease of use and ability to dig out a usable signal from the QRM.<\/li>\n<li><strong>AOR AR7030<\/strong>\u00a0for its simplicity, portability and the fact that it extract good sound\/audio quickly, even if a little noisy at times.<\/li>\n<li><strong>Bonito RADIOJET<\/strong> for its small size and its extensive feature set. It is ultra-mobile with a laptop.<\/li>\n<li><strong>ICOM R75\u00a0<\/strong>does the job and covers a wide frequency range. But lags in performance\u00a0relative to the other receiver tested, with a &#8220;nasal&#8221; sound and a DSP that does not keep its intended promises.<\/li>\n<\/ol>\n<p>About digital filters: the SDR and ICOM have them, the possibilities are extensive and allow adaptive filtering that others do not with analog filters. By cons they give a dry sound and sometimes add &#8220;snap&#8221; under whistles. Listening is overall less pleasant in comparison.<\/p>\n<p><strong>Receivers Advantages + \/ Disadvantages &#8211;<\/strong><\/p>\n<p><strong>Bonito RADIOJET<\/strong><br \/>\n+ Top technology, visual and many new features over the others on this point<br \/>\n&#8211; Complicated, metallic sound, emphasizing the sometimes painful receiver interaction with a computer mouse<\/p>\n<p><strong>Icom R75<\/strong><br \/>\n+ Great value at the present time<br \/>\n&#8211; Audio\u00a0and imperfect signal cleaning<\/p>\n<p><strong>AOR AR7030<\/strong><br \/>\n+ Simple and effective<br \/>\n&#8211; Ideal companion if it had a\u00a0notch filter: noise is present<\/p>\n<p><strong>JRC NRD-535<\/strong><br \/>\n+ Effective sensitivity and clean\u00a0audio<br \/>\n&#8211; Older technology,\u00a0less portable<\/p>\n<p>Note that this is a personal opinion: a computer geek will certainly get the most of performance and possibilities from an SDR like the Bonito RadioJet.<\/p>\n<p>The NRD-535 shows its age, will one day reach the end of its useful life\u00a0despite its robust construction. ICOM can cover up to 6m remaining mobile and has a good filter possibilities (DSP).\u00a0The AOR is easy, fast and gives a correct listening, general purpose.
