- The friendly ragchew net -
My name is Jim. I first caught the radio bug when I got a Rocket Radio, a little crystal set built into a red and white plastic rocket ship. It tuned by position of a rod which slid in and out of the nosecone. I spent many wonderful hours listening to the "Joy Boys of Radio" show with Willard Scott and Ed Walker, their humerous patter and the great daily skit, "As the Worm Turns - brought to you by Stop No More". Later in the evening Felix Grant took over with his jazz program, "The Album Sound". Terrific radio entertainment that continued to the last days of that golden era.
My interest in shortwave radio began when I discovered a Zenith Transoceanic radio in an upstairs storage closet. It had been presented to my Dad by his unit when he left Korea. I began punching different bands buttons and tuning around. Wow! I heard all kinds of really neat stuff - including ham radio operators. I was hooked on shortwave radio and the obsession has never let up.
Our family moved to Germany in mid-1961. I had been just about ready to take my Novice exam when I learned that a Noviceticket would not be accepted by the German
y authorities. So, I continued to study for another year, mostly struggling to get my code speed up to the 13 wpm needed to get a Conditional Class ticket (General Class exam by mail). Finally ready in late 1962, an Army Signal Corps Captain administered the test and six weeks later my first ham ticket arrived; with a K3 callsign. With US license in hand, I went to the Post Office in Stuttgart and was issued a DL4 callsign.
For the next 18-months I was active on 40-meter CW from Stuttgart where my first setup was a 40-meter dipole, a loaned Johnson Challenger transmitter and my Dad's Zenith Transoceanic using Japanese transistor SW radio tuned up/down 455 KHz to act as a BFO. Within a few months I had my own rig, an Eico 723 and a Hallicrafters SX-110. Still an avid SWL, I also held the SWL callsign DL4PE1AC.
We returned to the U.S. in mid-1964 and shortly thereafter moved from Maryland to Virginia. At that time the FCC assigned you a new callsign if you changed call areas. Consequently I was assigned K4AXF. Sometime around 1977 I upgraded to Extra class. For several years, I was active in the National Traffic System, serving as a net control station on the Virginia Net, as 4RN and EAN liason, and as VN Net Manager. By that time I had a set of Kenwood 599D twins, and later a Kenwood TS-530s, and still later, a Collins S-Line.

Built like a tank, this Kenwood TS-520 is almost fifty years old and still operates like it just the day it left the factory!
It covers 80-10 meters (no WARC bands), CW and SSB, with 100+ watts output. I love this rig on SSB; it's making a regular fone operator out of me. Three tubes: 2 x 6146 Final amplifier, 1 x 12BY7 driver amplifier all other circuitry is solid-state.
My 520 is equipped with the 500 Hz CW filter which makes it a very capable CW rig - and fun?
. . . Yeah buddy!
A word about filters: For those who have never used a CW filter, you would be surprised how much it improves the signal-to-noise ratio, i.e., significantly reducing the band noise that reaches the speaker. This benefit is over-and-above eliminating interference from any nearby signals.
The narrower the filter, the less noise and interference. Using a 250 to 300 Hz filter is great; but there is a catch - unless the receiver is tuned very slowly you may tune right past a station without hearing it. So, I tune with the 500 Hz filter, then switch to the 270 Hz filter for enjoyable ultra-quiet reception.
Another tip: Back the RF gain down until the background noise is very low, and the desired signal is still copyable. No RF gain on your rig? Switch in the attenuator. Do this one little thing and listening will be much more pleasant - CW or SSB.
I've owned and operated many of the modern DSP rigs. With their all their advanced DSP features and I found the experience very distracting. I seemed to get all wrapped up trying to get the very best signal out of it. Drove me nuckin futs!
Anyway, after cycling through one rig after another, I recalled how much fun I had with my Kenwood Twins and TS-530s back in the 70s; I thought, "Why not do that again?". So a few months ago I got ahold of this TS-530s. With a little control- and switch cleaning and a thorough alignment, it works like the day it came out of the factory.
Introduced after the TS-520s, the TS-530s sported additional features - digital
frequency readout, the WARC bands (30, 17, and 12 meters) as well as IF shift and XIT .
The final amplifier was designed around two 6146Bs with a 12BY7 driver.
I've equipped this rig with both 500 Hz and 270 Hz CW Kenwood filters. This rig has all the stuff I need for enjoyable CW operation without distractions.
I use the TS-530s for nearly all my CW work and the TS-520 for SSB, letting each do what it does best.
Realistic DX-150A Latest fleabay purchase
Heavily customized, this rig's previous owner obviously loved label-making. Sprucing it up will be fun. The price was right: 50 bucks.
Well, it didn't work at first, but cleaning and lubricating the slide switches brought the receiver back to life. And the alignment seems pretty good.
Hmmm . . . looks kinda cool as is. Maybe I'll just remove the tape residue and some of the stickers . . .
. . . . Well, once I got started on the cleanup, I couldn't stop myself. Turns out there was a very nice radio under all that...uh...decorating. Those huge knobs gave it a kinda cool, early Eddystone look, but they didn't turn very well. I found some semi-matching knobs on fleabay and put them on. So, I can show you the "AFTER" picture to go along with BEFORE.
Pretty lil thing, innit?
I've been tuning around the bands and this is a surprisingly good receiver. It's picks up CFZM Toronto "AM 740" very well and listening to the oldies on this thing is fun. In the mornings I tune in Radio Australia to get the news from the other side of the world. This receiver does pretty well on SSB, nice for listening to 40m ragchewing and HF air traffic control operations. Looks good, sounds great! (For the money, that is.)
I needed a general coverage receiver and this DX-150A will do nicely, until I can afford an Eddystone 1830.
Yeah . . . in my dreams!
Handy, Dandy Keyer
This is my PK-4 keyer. Runs on a 9v battery - like, forever.
The switch in the center selects either manual keys, keys off, or automatic keyer; the switch on the right switches selected key type to either of two rigs. A pushbutton switch supports programming or activating memories
On the rear panel are RCA plugs go to the main- or a second rig; 1/8" phone jacks for paddle, bug, and straight key.
CURRENT QTH - A bad day in Blackrock ( . . . is better than a good day in Northern Virginia).
I was active on all HF bands from the Virginia suburbs of Washington, DC, from 1964 to 2001.
In March 2010 my wife Pam, KA4EWG, and I moved to our retirement home just outside Grottoes, VA in the Blackrock trailer park. It's supposed to be a no-antenna community; even so, I threw up a "stealth" G5RV dipole in the trees at the edge of the woods behind our little double-wide. The antenna is very difficult to spot (circled in red, top center), even up close. I used black-jacketed #18 stranded wire and painted the end and center insulators with OD camouflage paint. The 60-foot run of coax is buried from the tree to the back of the house.
Pam built that wall from rocks collected in, and dug out of, the yard. She stacked 50 per day over two summers. It's now 90 ft long and comprised of over 12,000 rocks. She also cleared out the very thick undergrowth under those trees. Sadly Pam is now a Silent Key.

My 2003-2004 station featured a homebrew QSK T/R switch-keyer-sidetone (upper left), Johnson Adventurer and VFO and homebrew regen receiver (two cabinets below) and (mostly idle) Drake 2B and TS-870.

And my last motorcycle . . .
. . .that's about it for now. 73, Jim
