Ham Member Lookups: 3977


:Ham Radio Operator since 1974


SENSIBILITIES: One must harness the unknown (chance), and it becomes known: through (intuitive / creative / intellectual) process. It is like gradually navigating from point A, to point B.

DISCOVERY: the possibility of a better quality of life. This is my purpose and intention as a fine artist. So forget all of the obvious choices, and seek what is in the unknown.

DAVID RAPOPORT (a.k.a. Raportsky): is a self-promoting photographer, artist, and video artist, who has been creating photo-documentary, digital art, music, and portraits on his own, since 1978. "I seek to go beyond what is known about visual information, into some unknown space or knowledge of what is seen. I want to emphasize imagination, soul, identity, excellence, and the articulation of what this is all about: visually, and with the spoken word." ---dr.

NEXT WAVE: Ham Radio as an artform: this is a comprehensive guide to an: 1) inexpensive, 2) elementary, 3) functional, 4) minimal, 5) simple, 6) effective, 7) useful, and: 8) high-performance: radio (telecommunications) station. I aspire to get the most out of ham radio: in the urban center: with all of its advantages (and limitations).


KNOWLEDGE: 1) analog and digital radio signals (their transmission and reception), 2) radio waves: line of sight, and long distance, and: 3) the propagation of these signals (the many factors). I want to gain: knowledge, information, intelligence, and (a) sensibility (about the world). 


RADIO MAGIC: Imagine a QSO: 1) 100% in the clear, 2) from some foreign location (DX), 3) on an empty band (no other signals there), 4) some time in the late evening (at a convenient time), 5) with minimal noise (no QRM), 6) no fading signals (no QSB (ham radio Q-codes)), while: 7) conversing (for a very long time) about a subject that is: interesting, mysterious, technical, special, different, ground-breaking, sensational, and / or significant (whatever this can potentially be).


POSSIBILITIES: Many elements must be at play to accomplish this. One must be able to anticipate, and to navigate: what is known, and what is unknown. It usually happens unexpectedly, and you realize it: just as you turn on the radio, on any given day. This is Ham Radio at its best (for me, a most fulfilling experience).


CREATIVITY: My life's interest is: (the mystery of) fine-art photography. My specialty is portraiture (and mixed media). However, I experiment with still life. I utilize a number of different creative configurations, setups, and choices: I express myself in this visual artform (with other genres).


ART and TECHNOLOGY: I create a new juxtaposition of things, utilizing my: 1) practice, 2) skills, and: 3) knowledge. These are combined and aligned: with all of the forces of nature. Often, I am able to connect with: a) spontaneous, b) significant, c) usefuland: d) excellent: results, when everything is right.


MY STATION: For HF (high frequency), I am currently running a Yaesu FT-891 160-6 meter transceiver with up to 100 watts peak. Results vary with antenna conditions, and the SWR (standing wave ratio). I set up an Alpha Delta DX-EE multiband fan dipole antenna (with the 17 meter band added on). The center of the antenna is tied to a galvanized steel mast, on the top of my building (approximately 110+ feet high).


AN ACTIVE and DYNAMIC RADIO: One could never plan, believe, or expect, all of its capabilities. This was my discovery. The radio is about 6-1/4 inches wide, 2-1/4 inches high, and about 9 inches deep. It fits perfectly on my audio / visual / communications desk (or in a small briefcase, to travel).

TRIPLE CONVERSION, SUPERHETERODYNE RECEIVER: This is significant for the operation of the radio (listening), the way it selectively rejects noise, and (radio) interference.


SELETIVITY, STABILITY, and SENSITIVITY: It has a scope, and a bunch of RF/IF filters for QRM. The menu items are very easy to use, and the LCD screen is bright (adjustable dimming and contrast), and very easy to read. I also like the features such as: band / mode selection, and fast / normal tuning selectivity (you can select this with a button on the rig, right next to the tuning knob). I had the radio up and running in less than an hour: right out of the box. 


(Photo 06: 2017. Yaesu FT-891, and LDG AT100ProII Autotuner: dr).

SWR (STANDING WAVE RATIO): is less than 1.5:1: I made a bunch of long distance contacts on 20 meters, with excellent signal reports. There is total control of all of the RX functions. They work together: 1) DSP noise reduction, 2) IF shift, 3) contour, 4) bandwidth (of signal), 5) ATT (attenuator), 6) IPO (intercept point optimization), 7) AGC (automatic gain control), 8) noise blanker, 9) notch filter, and 10) RF gain control. These functions (filters) are extemely effective for tuning out noise, and separating the signals from it.

BASIC SETTINGS: They can be used (with adjustments) for the usual variables: 1) band conditions, 2) signal strength, 3) interference, 4) level of the noise floor, etc. You do not need to be an expert to utilize the RX (FT-891) functions. You just have to have a good ear, and the desire to learn how they work. I set all of my memory frequencies, with everything that is associated with them. Then, I checked out the scope: it is not a touch screen, so it is: a real ham radio. The span and signal levels are adjustable. I use the tuning knob to tune in signals: in the scope mode. This feature is exceptional for selective, fine tuning. Then, I saved the tuner settings into the tuner's memory.


(Photo 08: 2016. Yaesu FT-891, tuning with the scope: dr).


SETTING the AUDIO LEVELS: (TX: PRC level: 20, and Mic Gain: 55). I switched the audio control on the back of the stock microphone to: high (voice pitch), and I have been getting great audio reports all around. I hold the mic about 2 inches from my mouth, and speak in a normal voice, directly into the mic.


(Photo 09: 2016. Yaesu FT-891, RX menu items: dr).


FIRMWARE UPDATE: v. 1.06, enables the radio to remember the last filter settings (in memory): so when I turn off the radio, they would reappear (in function), when I turn the radio back on. I use the CAT software (Ham Radio Deluxe), to change the band, while keeping the filter settings (in memory), the same (across the spectrum). If changing (bands) from USB to LSB, or from LSB to USB, adjustments to the filter settings may be necessary: for optimal performance.


SHOPPING FOR an SDR: While I was deciding to buy the Yaesu, I was debating to get a state of the art SDR receiver (router or dongle) instead, use it with a separate transmitter, and control them with a (TX-RX) switch. Somehow, the software devices that were in my price range did not have enough of the features that I wanted. I am definitely looking for more than just HF. I am using Safari (web browser): Mac OSX Sierra 10.12.4. I like the Mac operating system for its stability, performance, and rock solid platform. However, there are less choices for SDR software for the Apple iMac Computer


STRAY RF: To improve the performance of the tuner, and avoid stray RF in the shack, I inserted a MFJ RF Islolator (choke), into the antenna feed: tuner side. This made a big difference for all of the above. LDG Electronics, tuner manufacturer: reccommended that I do this. I may try to install one at the antenna side, also.


HF BANDS: usually open up for a short time in the morning. I can work a few DX stations, on any given day. I usually contact them one right after the other. For example, this morning, I contacted a station from Venezuela (12:25 UTC), and one from Guernsey Island (12:32 UTC), on 20 meters. Then I worked France (13:49 UTC), on 17 meters. 


BAND CONDITIONS: On really good days, the bands are open for several hours. On exceptional days, the bands are busy for the whole day, and paet of the night. Since I get a lot of noise on 40 meters most of the time, I can only work the loudest signals on the band, especially at night. One way to check the band conditions, at any given time, is to log onto the Band Conditions Website.


MAKING CONTACTS: When I hear a weak signal, I wait for the signal strength to come up out of the noise (with more favorable propagation), and when it exceeds S-7, I usually can work them. For me, this is my secret for getting through pileups. Oftentimes, the signals can be stable. It is a fact that the conditions are almost at its lowest in several years. However, there is still plenty of satisfaction to be had, making the contacts, and having the conversations. Most any good HF station can work DX.


WINDOWS COMPUTER: It was easy to adapt to a Windows machine (for Ham Radio software), since I have been using Apple products: since 1984. I bought a Dell Optiplex 390 (mini desktop computer, refurbished: $130.00: I already had the monitor and keyboard in my posession), single processor Windows 7 PC, and I am running Ham Radio Deluxe (ham radio CAT software), and others. I use HRD to spot DX. It is not the most sophisticated package (and I am definitely not a computer programmer), but it works well for this setup (your results may be different).


ECHOLINK: works superbly on this platform: after I was able to establish the correct firewall settings. It is great for communicating worldwide, with clear audio. I make use of an old Sony stereo mic, for transmitting, and a small DX Engineering DXE-281 loudspeaker, for listening: on the PC.


SOFTWARE DEFINED RADIO, and FREE SDR: I am looking into free SDR websites on the internet. There are many SDR receivers at WEBSDR.orgListen though other people's: antanna and radio systems, via the internet, worldwide. K2SDR.com is a complete remote HTML-5 (HF) radio, in a web browser. I am able to receive signals similar to my own antenna, because they are located almost line of sight from New York City: in New Jersey. I tried listening at night, on 40 meters. The propagation was slightly less than average. Oftentimes, my own receiver and antenna system received louder signals than the website. I tried it again, and the results were different.


MY SECOND RIG: is an Icom IC-718 HF transceiver. The IC-718 is the standard, budget priced, mobile and / or base station radio. It is 10-15 years old technology: it is stable, and easy to listen to. Right now, this one is in storage.


MY COMMUNICATIONS SPEAKER: A good (may I say, "Zen"), audio solution: I took my Cobra HG S-500 speaker ($29. USD), and placed it on a (8x10x1-1/2 inch) hard wood art panel (with the opening of the panel: facing down). I placed another (8x8x1-1/2 inch) panel behind it (with the open side of the panel: facing away: the openings are not visible in the photo). The resulting configuration sounds like a big, hi-tech, communications speaker.

VHF / UHF: I operate a Kenwood TMV-71a, into a Diamond x200a vertical antenna. I programmed 440+ channels with Chirp radio programming software on my Mac, into the Kenwood, and Yaesu FT-60r (95 mile proximity from my home QTH, for repeaters). Also programmed my Tri-band BTECH UV-5X3 (for 220 mhz band), and Baofeng UV5-r V2+ (12 miles proximity, 2-meters, and 440 mhz band).


(Photo 11: 2016. Kenwood TMV-71a, Closeup: dr).


HANDY TALKIES: I also operate a Tytera TYT MD-380 Handy Talkie, for Digital Mobile Radio (DMR). I programmed it with the software that came on ther disc, on my PCVA3XPR is a great resource for DMR radio: specifically for the MD-380. I perfected the programming: with all of the talk groups that I want to use. I installed the MD380TOOLZ experiemental firmware, by KG5RKI. It has excellent features in addition to the standard versions. The MD-380 is an awesome radio!

CW OPERATIONS: I am experimenting with CW (continuous wave). I made my first successful contact on this mode after 35 about years. This was after adjusting the paddle settings, and practicing a little bit (at about 17 wpm). I tweaked the settings on the paddle a little more. Then, I changed the setting in the rig for the correct type of keyer paddle, and keyer weight. I realize that I need to practice my CW.

AFFILIATIONS: I am currently a member of: 1) ARRL (Amateur Radio Relay League), 2) LIMARC (Long Island Mobile Amateur Radio Club), 3) ECARS (East Coast Amateur Radio Service), and 4) Kings County Radio Club.


I received my Advanced Class license for Amateur Radio: morse code and radio telephone (from the Federal Communications Commission), in 1975.

Ham Radio: portable HF emergency communications system: Icom IC-718 transceiver, (left) 2-12 amp hour scooter batteries (center), and a sturdy photo tripod with vertical dipole attached, to a tripod extension tube (right): dr.)

PERFORMANCE of COMMUNICATIONS: I just wanted to see how the portable HF station could / can perform: specifically on 20 meters. The day before yesterday, I worked a local station (13 miles away), and yesterday, a station in Macon, GA. (about 800 miles away), with the vertical dipole set up inside my apartment. The signal reports weren't great, but as least I knew that my 15 watt SSB signal was getting out.

The bands were very active today, because of the Sweepstakes Contest. The antenna works best, when it is in the clear. This antenna configuration has a resonance bandwidth of about 80-100 khz, on 20, and about 40 khz on 40 meters.

The radio is powered by two scooter batteries. The antenna is a very simple design: I put it together myself, with some care, mindfulness, and intuition.

PORTABLE HF RADIO: is a nice way to get out of the stress of the city, relax, do something that I really like, and be useful to the community.

This is just the beginning of the discovery.

NEW YORK as THEME PARK (4k version is also available):

03:45. This is New York, the way you always wanted it to be. This series happened as a result of some unexpected, dissipation of energy, on paper. 

It started as 35mm still film images. 

The beginning stages were embellished, with art materials. Somehow, I envisioned what the results would be before the works were completed, specifically: while I was in the process of constructing them. 

This interpretation of the urban landscape was created to make others feel more alive, using my personal mind associations of my feelings about the place.

Original (finished) artworks: on paper: each one is 20.25x16.25 inches in size.
