center;\">The Early Years<\/h2>\n<p>Like so many other pirate operators, Dave&#8217;s \u00a0interest in radio began at an early age. \u00a0Dave was 7 when he first became interested in electronics. \u00a0This was a solo interest as nobody else in Dave&#8217;s family had any interest in radio or electronics. \u00a0Fascinated with radio and the reception of distant radio stations on the AM dial, Dave&#8217;s interest in DXing began in 1962. \u00a0Dave was an avid DXer back in the 1960s and enjoyed collecting QSL cards from distant AM radio stations. \u00a0One of those stations that Dave logged in 1963 was 1580 WAMY out of Amory, Mississippi. \u00a0Dave mailed off a reception report which was kindly answered with a nice letter that verified his reception but sadly did not include a coveted QSL card. \u00a0The station explained that it did not have any cards prepared. \u00a0Dave set out to fix the situation by taking it upon himself to print up a box of custom designed WAMY verification cards that he had printed using his own money and skills learned in the high school print shop class. \u00a0Dave graciously mailed the box of blank QSL&#8217;s to the Amory station. \u00a0To this day, WAMY has been sending out Dave&#8217;s QSL cards for correctly verified reception reports!<\/p>\n<figure id=\"attachment_632\" aria-describedby=\"caption-attachment-632\"

wasn&#8217;t until 1969 that his interest in transmitters and broadcasting would be realized. \u00a0In search for some suitable wire for a receiving antenna one day, Dave crossed paths with Roy Fuller in 1969. \u00a0Roy was the chief engineer at WGHQ on 920 kHz in Kingston, NY, and WTRY in Albany prior. \u00a0Roy was a kind hearted person who was more than willing to mentor the young Dave on all things concerning radio. \u00a0After witnessing the 5,000 watt Collins transmitter that WGHQ employed, Dave realized his true calling belonged in broadcasting, and especially high powered AM transmitters. \u00a0Dave found himself at the transmitter site nearly every day after working the night shift as a welder at the local cement mill. \u00a0He could often be found trading coffee and donuts for Roy&#8217;s\u00a0tutelage. \u00a0Dave worked closely under Roy at the transmitter site for a year. \u00a0He often helped the elder engineer with tasks that had become too\u00a0difficult\u00a0for Roy due to his very poor eyesight that included logging transmitter readings. \u00a0Soon Roy encouraged Dave to study for the first class phone exam in order to obtain his license. \u00a0After a year or two of difficult studying for the exam, Dave failed the 6 hour long test by just two questions. \u00a0Not content to simply memorize questions, Dave had\u00a0a deep desire to understand the questions and to understand the cause and effect of every detail, this being the mind of a great engineer. \u00a0During the next year, Dave took the exam again and passed with flying colors. \u00a0Having his license, Dave was now in the position to pursue a career as a chief engineer for a radio station, or so he thought. \u00a0Roy explained to Dave that the prestige of chief engineer had long expired, and that those glory days were just a distant memory. \u00a0&#8220;Today, station owners are always looking for the cheapest way out!&#8221; Roy insisted. \u00a0Dave was crushed by this but he put his trust into the advice given by his good friend. \u00a0After all, Roy hadn&#8217;t steered him wrong before.<\/p>\n<h2 style=\"text-align: center;\"><\/h2>\n<h2

the 1960s<\/figcaption><\/figure>\n<p style=\"text-align: left;\">Few people are probably aware of WJDI&#8217;s early origins. \u00a0The thought of starting up a pirate radio station doesn&#8217;t usually\u00a0conjure\u00a0up thoughts of locating your station out of the town mayor&#8217;s oil business, but then Dave wasn&#8217;t the typical pirate broadcaster. \u00a0Dave worked for the Kingston mayor&#8217;s oil company as a radio repair man, fixing the two-way radios used in the oil trucks. \u00a0It is from this location that Dave launched WJDI in 1970 using \u00a0a 7-1\/2 watt transmitter on 1580 kHz. \u00a0This early transmitter was a Meissner Signal Shifter that used plug-in grid coils wound for amateur radio frequencies. \u00a0Dave rewound the coils for operation on 1580 kHz, and in no time he was on the air. \u00a0Other modifications were needed to the CW rig in order for his voice to be heard, so Dave used a phonograph amplifier that he had on hand with its output connected to the Signal Shifter through a transformer. \u00a0The antenna used at the time was a 100 foot long wire. \u00a0If the station were to operate\u00a0alongside legit stations on the AM dial, a proper set of call letters would need to be procured. \u00a0Dave picked the call letters W-J-D-I since no record of any legal stations bearing that call could be found during the mid 1960s. \u00a0With the transmitting &#8220;bug&#8221; firmly in place now, Dave knew that more output was needed and a larger transmitter would be required to fulfill his desire to broadcast to more people at greater distances.<\/p>\n<p style=\"text-align: left;\">As Dave poured over the want-ads that lined the back of amateur radio magazines like CQ and QST, he discovered a ham in Long Island selling a Collins 30K transmitter rated for about 300 watts. \u00a0Since the transmitter only covered 3.5 mHz and higher, Dave found himself winding a new set of plug-in coils with the aid of his Millen grid dip meter. \u00a0Once the new coils were wound and in place, he was able to operate the big transmitter on 1580 khz which covered about 10 miles in daylight on the old wire antenna. \u00a0Dave was able to pull it off for some time, but not without some quick troubleshooting to work through first. \u00a0It seems that whenever the big Collins hit modulation peaks, the lights in the office of the business would flicker and dim. \u00a0Dave remedied the situation with \u00a0a few capacitors to ground and broadcasting continued on.<\/p>\n<figure id=\"attachment_639\"

class=\"wp-caption-text\">The Collins 30K1<\/figcaption><\/figure>\n<p style=\"text-align: left;\">Roy Fuller was aware of the first low powered transmitter that Dave was using but the mentor never discouraged Dave from continuing. \u00a0Instead, Roy offered up several boxes of 833A&#8217;s vacuum tubes that he had collected from the previous stations that he had worked at. \u00a0In four month&#8217;s time, Dave put those tubes to work and built a home-brew transmitter around them. \u00a0The 833A rig used 4-400 tubes for the modulators. \u00a0His signal was now up to 500 watts on 1580 kHz from a new location several miles north of Kingston. \u00a0Needing a suitable antenna to handle the increased power output, Dave&#8217;s\u00a0ingenuity\u00a0kicked in and he devised a 150 foot thin wire vertical supported by a hydrogen filled weather balloon obtained from Fair Radio Sales. \u00a0The higher powered transmitter and new antenna gave WJDI about 30 miles of solid coverage. \u00a0This was reliable enough that Dave started selling advertising on WJDI in 1972. \u00a0Commercials were sold to Uncle George&#8217;s Hot Dogs in Kingston in exchange for a few bucks (and free hot dogs of course). \u00a0WKNY, a legal AM in Kingston, learned of WJDI&#8217;s ad sales and became infuriated by this. \u00a0The FCC was promptly notified of the competing unlicensed station on 1580. \u00a0Roy Fuller was also notified by an engineer at WKNY that an unlicensed station was\u00a0illegally pirating in the area. \u00a0It was no surprise to Roy that this was Dave&#8217;s work, but being the good guy that Roy was, Dave&#8217;s cover would remain cloaked. \u00a0Roy did give Dave a stern warning encouraging the pirate to let things cool off for a bit. \u00a0Dave took Roy&#8217;s advice once again and WJDI went silent for several weeks. \u00a0It wasn&#8217;t until thirty years later that Dave met up with a listener who heard WJDI in those early days on 1580 from 100 miles away in\u00a0Connecticut.<\/p>\n<p>In 1977, Dave moved to Arizona to work for Motorola Research on the Voyager II project and WJDI was put on hold. \u00a0Dave returned to New York in 1986 where he worked as chief engineer overseeing the installation of a cable television system in a 3,000 unit apartment complex located in Manhattan. \u00a0Three years of this and Dave was burned out from the stress of the high paying job and thoughts of WJDI began to fill his mind again.<\/p>\n<h2 style=\"text-align: center;\"><\/h2>\n<h2 style=\"text-align: center;\"><\/h2>\n<h2 style=\"text-align: center;\"><\/h2>\n<h2 style=\"text-align: center;\">1,200 Watts<\/h2>\n<p>Dave set out to construct a new transmitter and studio which would become the radio station that he would use during the Spring of 1989 through the Fall of 1989. \u00a0The home-brew transmitter had an output power of 1,000 to 1,250 watts and operated out of\u00a0West Shokan, NY.<\/p>\n<figure id=\"attachment_647\"

transmitter.<\/figcaption><\/figure>\n<p>In the photo above, the large custom built transmitter is visible to the right of the desk. \u00a0The 20 watt exciter used to generate the signal on 1620 kHz sits on top of the transmitter cabinet. \u00a0The exciter was obtained from 1350 kHz WCBA in Corning, NY. \u00a0The final tube in this transmitter was a 4-1000 and was fed by the 810 triode modulator tubes shown in the lower rack of the transmitter cabinet. The cabinet also housed the power supply running about 2,500 volts DC. \u00a0A Dynaco amplifier was used to drive the audio to the 810 modulators. Dave had a special transformer wound to his specifications that took 8 ohms stepped up to 800 ohms at 50 watts. \u00a0This provided a good frequency response since it contained five primaries and five secondaries that were paralleled together to increase response. \u00a0All of the music was produced by a single CD player and cassette deck. \u00a0An inexpensive Radio Shack mixer was used to mix the music and audio from the microphone. \u00a0The slight echo effect that some may remember from WJDI was generated by an old Lafayette reverb. \u00a0Dave brought in a Collins R390a which served as the station&#8217;s monitor. \u00a0The IF of the R390a was fed into an old audio oscilloscope allowing Dave to monitor the station&#8217;s signal during a live broadcast to insure good modulation and signal.<\/p>\n<p>This is the first serious transmitter that Dave fabricated for WJDI that had any decent signal coverage. \u00a0This transmitter would later be salvaged for &#8220;donor parts&#8221; to serve an even larger transmitter as Dave took WJDI to even greater heights.<\/p>\n<h2 style=\"text-align: center;\">2,500 &amp; 5,000 Clear Watts<\/h2>\n<p>Dave recalls that he got the idea for a larger transmitter while visiting &#8220;a place that had an old AM transmitter&#8221;. \u00a0It was at this moment that Dave&#8217;s obsession to strive for the most powerful pirate station gained traction. \u00a0The 2,500 watt rig consisted of a modulator and finals enclosed in separate rack\u00a0cabinets. \u00a0The modulator used 833A triodes \u00a0which pushed the 4-1000 finals to their absolute limit to reach those 2,500 &#8220;clear watts&#8221; that were heard up and down the East coast and Midwest in late 1989 on 1620 kHz AM. \u00a0The transformers used in the modulator rack were salvaged from 1350 WCBA in Corning, NY &#8211; &#8220;the best iron ever made!&#8221; laments Dave. \u00a03,800 volts on the plate of the final tube and 3,000 volts on the 833A modulator tubes allowed WJDI a 2,500 watt output power with good punch to the audio. \u00a0A three diode switching arrangement was used to limit the negative cycle of the audio in order to push the positive peaks to get more than 100% modulation in the positive direction. \u00a0Dave would later reuse the 833A modulators for his next big project. \u00a0The same WCBA 20 watt exciter was used to drive the transmitter as had been used in the earlier 1,200w transmitter. \u00a0Components in the audio chain remained mostly the same and the same R390a again served as the studio&#8217;s monitor.<\/p>\n<figure id=\"attachment_651\" aria-describedby=\"caption-attachment-651\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/2500w-transmitter-21ja13.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-651\" style=\"border: 2px solid black;\" src=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/2500w-transmitter-21ja13.jpg\" alt=\"WJDI's 2,500 watt transmitter, 1991\" width=\"600\" height=\"450\" \/><\/a><figcaption id=\"caption-attachment-651\" class=\"wp-caption-text\">WJDI&#8217;s 2,500\/5,000 watt transmitter used from December 1989 through December 1991<\/figcaption><\/figure>\n<p>Dave operated at 2,500 watts for only a few months before the rig was upgraded once again to a higher output power. \u00a0The 833A modulator tubes were replaced by 3-1000Z&#8217;s and the finals were replaced by a single 4CX5000. \u00a0Issues arose using this arrangement as the modulator transformer was unable to keep up due to power supply constraints. \u00a0Modulation peaks were diminished which limited the transmitter from delivering a good &#8220;punch&#8221; on audio peaks, especially at the lower frequencies. \u00a0 Dave worked through this problem by limiting the low end frequency response which prevented the issue with the modulation transformer. \u00a0The plate current to the\u00a04CX5000 final was also increased to get the power out, but at the expense of efficiency.<\/p>\n<p style=\"text-align: center;\"><a href=\"http:\/\/amdxer\/wordpress\/wp-content\/uploads\/2014\/01\/dsc_0002.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-709\" src=\"http:\/\/amdxer\/wordpress\/wp-content\/uploads\/2014\/01\/dsc_0002.jpg\" alt=\"DSC_0002\" width=\"614\" height=\"428\" srcset=\"https:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2014\/01\/dsc_0002.jpg 1418w, https:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2014\/01\/dsc_0002-300x209.jpg 300w, https:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2014\/01\/dsc_0002-1024x714.jpg 1024w, https:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2014\/01\/dsc_0002-768x536.jpg 768w\" sizes=\"auto, (max-width: 614px) 100vw, 614px\" \/><\/a><\/p>\n<p>Dave actively operated this transmitter out of West Shokan, NY on 1620 kHz for three years. \u00a0WJDI featured current music of the era with clever parody commercials between songs such as the famous dioxin &#8220;No Roach!&#8221; ad. \u00a0WJDI was on frequently and after three years, the\u00a0Federal Communication&#8217;s Commission took notice. \u00a0In January of 1991, the FCC arrived in Kingston to investigate complaints of radio interference. \u00a0The FCC stepped onto Dave&#8217;s property without a warrant so Dave refused them access to his home. \u00a0The FCC officials were eventually led off Dave&#8217;s property by state troopers and held until a phone call was placed to the captain in charge of the FCC at the time. \u00a0The federal agents were released within an hour. \u00a0Following this, several threatening letters were received by Dave from the FCC, but no legal action was ever taken. \u00a0WJDI would remain off the air for five years but would be poised to return in a most dramatic way.<\/p>\n<h2 style=\"text-align: center;\">&#8220;15 to 18 kw ought to do it&#8221;<\/h2>\n<p style=\"text-align: center;\">A year had passed since the FCC had knocked on Dave&#8217;s door. \u00a0By this time the thought of building the most powerful AM pirate transmitter began to consume all of Dave&#8217;s thoughts. \u00a0Dave understood the limitations of the previous 5,000 watt transmitter and realized the only way to overcome those challenges would be to design and construct a new transmitter from scratch. \u00a0&#8220;15 to 18kw ought to do it!&#8221; Dave thought. \u00a0From this point forward Dave was completely dedicated to the project of constructing a home-brew 15kw AM radio transmitter. \u00a0The project dominated his life, it consumed his every thought. \u00a0 Dave worked the design on the 15kw rig for six months before construction even began. \u00a0When construction did begin, it took many years of building and gathering the necessary\u00a0components together. \u00a0A lathe was purchased in order to make the mechanical parts for the transmitter. \u00a0Unable to locate pre-made cabinets large enough for his needs, Dave hand built the transmitter\u00a0cabinets and chassis\u00a0from bent aluminum sheet and a TIG welder was purchased to heliarc the custom aluminum pieces together. \u00a0Welding came natural to Dave and he mastered the lathe during his tenure at Motorola.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-662 alignleft\" style=\"border: 0;\" src=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/wjdi-daily-freeman-newspaper-11-08ja91.jpg\" alt=\"WJDI DAILY FREEMAN NEWSPAPER 11 08JA91\" width=\"337\" height=\"276\" \/><\/p>\n<figure id=\"attachment_665\" aria-describedby=\"caption-attachment-665\" style=\"width: 369px\" class=\"wp-caption alignright\"><a href=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/transformer-21ja13.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-665   \" style=\"border: 2px solid black;\" src=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/transformer-21ja13.jpg\" alt=\"The 300 pound transformer used for the 15kw 1996 broadcast\" width=\"369\" height=\"312\" \/><\/a><figcaption id=\"caption-attachment-665\" class=\"wp-caption-text\">The 300 pound transformer used for the 15kw 1996 broadcast.<\/figcaption><\/figure>\n<p>The height of the transmitter was so tall that it required no less than three people to\u00a0maneuver\u00a0and transport it. \u00a03CX3000A7 modulator tubes were utilized in the design at a cost of $750 each. \u00a0The modulator was driven by a solid state FET driver. \u00a0The final output tube was a military spec.\u00a04CX15,000J. \u00a0With such power, one certainly wonders about the logistics involved in supplying the needed energy to power the transmitter. \u00a0Dave secured a pair of 300 pound &#8220;pole pig&#8221; transformers. \u00a0Only one was used and the second was simply there as a backup if needed during the big New Year&#8217;s Eve broadcast. \u00a0The transformer supplied the 15kw rig with a lethal 9,600 volts at 4+ amps DC. \u00a0Due the large size of the transformer, it was located in another room separate from the transmitter and studio and the high voltage routed through a cable. \u00a0As part of Dave&#8217;s old-school design of the rig, no less than 320 diodes rated at 1,000 volts each at 6 amps were used in the rectifier assembly. \u00a0A fan was used to blow cool air over the assembly to keep the temperature under control.<\/p>\n<p>Expenses were of little or no concern at this point. \u00a0$10,000 was spent on the studio equipment alone for the famous New Year&#8217;s Eve 1996 broadcast. \u00a0Two Revox and two Tascam reel to reel decks were used in the studio, two mixing consoles, a compressor, four cart machines and three microphones. \u00a0The microphones included a Shure 556 with a custom preamp that Dave built himself and a pair of RCA 44BX&#8217;s.\u00a0 A Harris RF-1310 exciter was procured to generate the 1620 kHz signal. \u00a0A Harris RF-590 receiver was obtained and used as a station monitor. \u00a0An A300 ENI amplifier was used to drive the RF signal to the transmitter. \u00a0Audio was fed through a high end Inovonics audio processor that gave the station 125% positive peak audio while limiting the negative peaks to 90%.<\/p>\n<figure id=\"attachment_671\" aria-describedby=\"caption-attachment-671\" style=\"width: 407px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/wjdi-xmitter-unload-17de96.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-671\" style=\"border: 2px solid black;\" src=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/wjdi-xmitter-unload-17de96.jpg\" alt=\"WJDI XMITTER UNLOAD 17DE96\" width=\"407\" height=\"337\" \/><\/a><figcaption id=\"caption-attachment-671\" class=\"wp-caption-text\">Dave Schneider standing proudly after having just unloaded the 15kw transmitter in preparation of the famous 1996 broadcasts.<\/figcaption><\/figure>\n<figure id=\"attachment_670\" aria-describedby=\"caption-attachment-670\" style=\"width: 361px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/wjdi-jim.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-670 \" style=\"border: 2px solid black;\" src=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/wjdi-jim.jpg\" alt=\"\" width=\"361\" height=\"244\" \/><\/a><figcaption id=\"caption-attachment-670\" class=\"wp-caption-text\">Dave&#8217;s friend &#8220;Jim&#8221; breaks for a pose during the testing phase of the 15kw transmitter (shown here) just before the Christmas Eve 1996 broadcast.<\/figcaption><\/figure>\n<p>Dave&#8217;s goal of building a 15kw pirate station was accomplished and now it was time to set sail on the airwaves with it. \u00a0The 15kw transmitter was located at the home of Jim, one of Dave&#8217;s close friends. \u00a0Jim had enough land to lay out the 300 FT antenna and also had the required 400 amp electrical service. \u00a0Without Jim, the 15kw WJDI broadcasts would not have been possible.<\/p>\n<p>Only two official WJDI broadcasts were made on 1620 kHz using this rig: Christmas Eve 1996 and New Years Eve 1996. \u00a0Dave also used the transmitter three times on the amateur radio bands during this time period. \u00a0When used for CW operation (not using the modulator), the power output was once recorded at 32,000 watts with the plate voltage at 12,000 volts DC. \u00a0As one can imagine, the energy consumption of the transmitter was massive, as Dave discovered on Christmas Eve. \u00a0At 10:30pm during the Christmas Eve broadcast, operations came to an instantaneous halt as the power went out. \u00a0Dave knew this wasn&#8217;t a tripped breaker as he was &#8220;clamped on&#8221; before the breaker to prevent such an event from happening. \u00a0The cause of the power loss was much more concerning. \u00a0Dave set out to troubleshoot the problem and discovered the input power coming in from the pole transformer read zero volts on his meter. \u00a0The issue was upstream at the pole. \u00a0Dave phoned New York State Gas &amp; Electric, the utility supplying Jim&#8217;s home with power. \u00a0Since it was a holiday, the chances of getting a crew to the location seemed slim. \u00a0Dave fabricated a story of having rare and expensive tropical fish that would soon perish due to temperature losses inside the tank if power was not restored quickly. \u00a0The ploy worked and soon Dave and Jim were visited by the utility company. \u00a0Via bucket truck, the crew from the electric company inspected the faulty transformer on the pole as Dave overheard them comment about the transformer being so hot on that cold December night. \u00a0The crew suspected a dead short of some type and probably weren&#8217;t buying into Dave&#8217;s fish tank story at this point. \u00a0Dave realized this and proceeded to &#8220;tip&#8221; the guys a $100 each for coming out on Christmas Eve. \u00a0Within an hour and a half, the crew had installed a heavier transformer on the pole and WJDI was on the airwaves once again.<\/p>\n<figure id=\"attachment_672\" aria-describedby=\"caption-attachment-672\" style=\"width: 614px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2013\/11\/wjdi-xmitter-xmas-eve-1996.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-672\" style=\"border: 2px solid black;\" src=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2013\/11\/wjdi-xmitter-xmas-eve-1996.jpg\" alt=\"WJDI XMITTER XMAS EVE 1996\" width=\"614\" height=\"419\" srcset=\"https:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2013\/11\/wjdi-xmitter-xmas-eve-1996.jpg 1126w, https:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2013\/11\/wjdi-xmitter-xmas-eve-1996-300x205.jpg 300w, https:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2013\/11\/wjdi-xmitter-xmas-eve-1996-1024x698.jpg 1024w, https:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2013\/11\/wjdi-xmitter-xmas-eve-1996-768x524.jpg 768w\" sizes=\"auto, (max-width: 614px) 100vw, 614px\" \/><\/a><figcaption id=\"caption-attachment-672\" class=\"wp-caption-text\">The WJDI 15kw transmitter and studio used for the Christmas Eve, 1996 broadcast.<\/figcaption><\/figure>\n<figure id=\"attachment_699\" aria-describedby=\"caption-attachment-699\" style=\"width: 614px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/wjdi.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-699\" style=\"border: 1px solid black;\" src=\"http:\/\/amdxer.com\/wordpress\/wp-content\/uploads\/2024\/08\/wjdi.jpg\" alt=\"WJDI\" width=\"614\" height=\"411\" \/><\/a><figcaption id=\"caption-attachment-699\" class=\"wp-caption-text\">Another shot of the WJDI 15kw transmitter.

original 15kw transmitter is still partly operational. \u00a0The modulator section was torn down and the parts sold off, including the modulator tubes. \u00a0The modulation transformer and reactor were sold to a close friend of Dave&#8217;s, a radio amateur, for the price of $1. \u00a0The other half of the 15kw transmitter was sold off to another amateur and occasionally sees use today on the ham bands, but for CW service only. \u00a0On CW, the transmitter has been pushed to 32kw output into 50 ohms, with the plate voltage at 12,000 volts DC!<\/p>\n<p>It&#8217;s been over a decade since WJDI last hit the airwaves and made a lasting impression on so many DXers across North America and beyond. \u00a0Though at the age of retirement, Dave still enjoys radio in many different ways. \u00a0Dave keeps busy working on broadcast transmitters by providing his expert services to several radio stations in his local area. \u00a0Dave is also active in the radio hobby when designing numerous communication related items for vintage receivers, including a unique design for an AM loop antenna. \u00a0Dave also has a great talent for restoring vintage ribbon microphones which he has
