Dear Bill and Pete,
It is a real honor to have my book reviewed by DSB guru Peter Parker VK3YE, and to have him do the review from the iconic “DSB-SSB” pier in Melbourne, Australia. Check out the video (above). Thanks Peter.
Hi Bill & Pete,
I would like to claim an entry in the SolderSmoke Homebrew To Homebrew
(HB2HB) log. Here’s the story. On Sunday 24th April 2016 I drove two
and a half hours north east of Melbourne into the edge of the Great
Australian Dividing Range, to climb two summits, for the fun of
operating my 40 meter SSB QRP (5 watt) rig in a beautiful, RF-quiet
setting, and to activate two Summits Of The Air (SOTA) peaks.
My first summit was Mount Bullfight
(http://www.sotawatch.org/summits.php?summit=VK3/VN-002), in the
Rubicon Ranges, at 1,490 meters ASL not high by American or European
standards but a good heart-racing climb through thick Australian bush.
After a successful activation with good signal reports into Tasmania
(VK7), around Victoria (VK3) and New South Wales (VK2), I descended,
and drove about 2 miles up the valley to an adjacent SOTA summit,
Pyramid Hill (1,314 meters) where the activation also went well. Just
as I was finishing up with the chasers, Peter Parker VK3YE called me,
operating portable from his beloved Chelsea Pier, and we had a very
pleasant beach-to-summit ragchew QSO. The RF path is about 62 miles.
Peter was running his MDT double sideband rig, with 2 watts. I was
using my MST400, with 5 watts SSB. Both rigs are kit radios from OzQrp
(http://www.ozqrp.com/). Both are assembled by hams — I built my
MST400 18 months ago and Peter was using the MDT rig that OzQrp
founder Leon, VK2DOB designed, built and kitted, the one he sent to
Peter for a YouTube review. So it was built by a ham, just not by
Peter.
Now, I know that there may be some, possibly even you Bill, who may
question the legitimacy of my claim on a coveted HB2HB log entry in
this particular case. I can assure you that we did experience the Joy
of QRP/P operation, Peter basking in the late afternoon Australian sun
on a beach and I on the mountain top. And to further add authenticity
to my HB2HB claim we discussed QRP, aerial experiments, and ‘whats on
your bench’ topics for a full 20 minutes.
However, I would not want to risk disturbing the wrath of the Radio
Gods with a dubious claim.
I admit that neither radio was scratch-built, on copper board
ugly-style, or had the form of a wild birds-nest of separate modules
and interconnections, with parts loosely screwed onto an Italian
chopping board or a discarded lump of wood. Indeed, neither can it be
claimed that both operators built their rigs. So I will take a
rejection of my request with acceptance and dignity, acknowledging
that you are duty-bound to maintain the highest of standards, and that
entry into the SolderSmoke HB2HB log is not to be granted without
proper consideration.
I do understand that you may feel that accepting this QSO could set a
dangerous precedent and risk opening the flood gates to a tsunami of
dubious HB2HB QSO claims from hams using minimal assembly rigs, like
some of the Elecrafts. Who knows, some individuals might even be
tempted to claim HB2HB QSOs from VHF FM hand-helds after managing to
screw on the rubber-ducky antenna. Even unboxing a shiny new
Yae-com-Wood is, to some, a form of ‘handiwork’.
Bill, the decision is yours. Peter VK3YE and I look forward to your
decision. Judge wisely.
73 from down under, Paul VK3HN, with agreement to this claim from Peter VK3YE.
Details of this day of activations are on my blog at:https://vk3hn.wordpress.com/

I really liked Eric’s interview with the Peter “The Wizard of Melbourne Beach” Parker aka VK3YE. What a great Knack story! There he was, trolling the garbage dumps of Western Australia, looking for discarded electronics. Using the LO of one broadcast receiver to demodulate SSB signals coming in on another… Great stuff! Check it out:
We are honored to induct Alan Wolke W2AEW into the Colorburst Liberation Army. And for his valiant effort to build and explain a MMM Low-Pass filter, he is immediately promoted to the rank of CBLA Two Star General. Congratulations General Wolke.
As is the case with all of his videos, this one has already had an impact far and wide. Ian writes from far-off Western Australia:
It made me appreciate the benefits of an LPF more fully. It’s always been clear to me that the harmonics would get rolled off, but in my head I hadn’t made the connection between that and the improvement to the beautiful smooth sine wave that we are working towards.
Anyway, I thought you, and your mate Steve “Snort Rosin” Smith may be interested.
73,
Ian VK6MIBSeriously, there is a lot to be learned from the lowly Mighty Mite especially regarding impedance matching; not to mention LC circuits, link coupling, amplifiers, oscillators, etc. . What fun!
73…….SR
New Zealand and Australia seem to produce an amazingly high percentage of the world’s double sideband transceivers. Charlie ZL2CTM adds to the count. He took inspiration and circuitry from DSB hams in both countries and produced this beautiful DSB transceiver. It is obviously — as Charlie notes — chock full of soul. I definitely identify with his comment about “taming some kind of electro-mechanical machine” and also, of course, with his remark about the feelings that come with putting a homebrew rig on the air. So follow the advice of Charlie! Build a DSB rig and put it on the air! Make this your ham radio resolution for 2016! Give it a go!
The wizard of Melbourne Beach, Peter Parker VK3YE, has written a book about QRP. Check it out here.
Peter is a true QRP guru. His Beach 40 transceiver is shaking the ether from locations around the world. I am really glad that he put that Melbourne dock on the cover. That dock has been the test site for many of Peter’s amazing creations. The railing has supported many great antennas. So many wonderful YouTube videos have been recorded there. There really should be a plaque or something…
Peter’s book is available as an e-book from Amazon. Details on how you can get it are here”

Thanks Peter for this important addition to the QRP literature.

Peter Parker has a double dose of The Knack: Not only is he a great rig builder, but he is also a very skilled teacher. His videos provide really excellent descriptions of how he selects, designs, and modifies the stages that make up his magnificent rigs. You can learn a lot from these videos. Thanks Peter.

Alf, VK2YAC, wrote to Pete thanking him for the inspiration provided by the LBS project that Pete and Ben launched via QRP Quarterly. Alf has obviously taken to heart Pete’s recommendation re using a BIG breadboard.
On his web page Alf writes: “Build your homebrew station and join the revolution, it’s lots of fun!” We’re with you Alf!
Alf has more great pictures of his BBR-40 rig and short descriptions of the sub-circuits he has used. Note Si5351 with Arduino Pro-Mini for BFO and VFO.

Last week during the big St. Patrick’s day solar eruption/CME impact I (with the help of the radio gods) managed to work Roy VK6MV in Western Australia. (A video of Roy working QRP pedestrian mobile stations in the UK appears above.) Could it have been that that miraculous contact was ALSO my first ever homebrew SSB to homebrew SSB QSO? I e-mailed Roy to find out. Alas, it was not. But OM Roy sent some interesting info on his station and especially his antenna. Excerpts from his e-mail:
Hi Bill
Thanks for the qso and the email.
yes another ‘fadeout’ but we have had many over the years haven’t we ?
Things have changed a lot since 1963 when I had my first license as G3SML.
We came to Aus in 1977 with 3 sons and now have 24 Grandies 13 Grandchildren; 11 Great Grandchildren.
I liked the early Plessey IC’s when they came out ~
Carry on with home brew and get that personal enjoyment out of it, it gives you a boost I am sure. NO I was not on the home brew I was on the Icom IC740 which I bought about 5 years ago at the WA Hamfest it had a fault of jumping to different frequencies, etc. I could not find its intermittent fault at all, but on the internet a ‘W’ ham in your country posted the same fault with explanations etc,
and it cured it,
So I was on that Rig + a home brew linear pair of old 813’s in Grounded Grid and a Voltage doubler for the + 2 kv, I could not get the smoothing caps for that voltage so got hold of 3 metal canned ones 800 volt, then got some plastic drain pipe to insulate the cans from ground & then put them all in series with equalising resistors,
and it worked.
Yes I was on the rhombic ~ amazing antenna for a fixed point to point contacts ~
why a rhombic you may ask well when in the Uk I used to work VK2NN [and others] Tom with his farm of rhombics his setup much larger, and I thought one day I would love to put one up. Eventually with our moving to Aus’ then came down here with its 8+ acres the opportunity led itself to put one up, and as I used to work into Europe/UK a lot that direction picked. first I put one up a bigger one than now, but it did not work that good. Moral the longer you go the higher it needs to be
So a smaller version tried using the contours of the land at a height above sea level of 1260 feet asl helps. Using 12 gauge usa hard drawn copper wire I needed winches and turnbuckles etc to pull it up, one end is on the 60 ft tower, the others on assorted Wooden Poles +
The termination R for the rhombic is a 3 element TH3 Tribander ~
think of it why waste power into a whopper of a Resistor ~
this is not my idea but came from ~ Nano VK6UN why not connect it to another antenna with how to do it came from now SK Les Moxon G6XN
a clever man how to make a balun out of old ferrite rods from transistor radios,
Will close now my half a dozen lines of text are expanding to much
Cheers have fun Roy VK6MV

There I was. 0900 UTC (0 Dark Thirty local), the morning after the big March 17 St. Patrick’s Day Coronal Mass Ejection Impact. Solar Flux Index: 116. A Index: 117! I’d never seen the A Index that high. When I got home from work on March 17, I had turned on the BITX 20 and heard nothing but white noise. No signals. Nada. Zilch. So the following morning my expectations for 20 were quite low. I tuned across the whole band, again hearing nothing. But wait… there was one signal. And he was calling CQ. With an Australian accent. VK6MV! The only signal on the band. I called him with my recently fixed BITX20 (with .12 kW amp) and a dipole. No problem. We had a nice contact.
A look at Roy’s QRZ page shows that he is a fellow homebrewer. Clearly, the radio gods were making a statement here.

I’ve amassed the parts for my 12v Regen Rx inspired by a projects from VK3YE and an audio amp, using a pair of 12AU7’s. I’ll publish more about that soon on my blog.
In the mean time, I’d like to thank you guys for inspiration on the si5351 VFO in use with various projects. After we found the first articles by NT7S, we discussed that there are a lot of possibilities.
I’ve just finished my build of an Arduino controlled SDR transceiver prototype using the Si5351A.
See attached images. Lots of collaboration with Mark VK5QI and David VK5DGR. More at; http://openradio.net.au/index.
This week I’m tinkering with the LPF for 20meters. Puts out a whopping 20mW.
Everything is on schedule for the presentation using this SDR at Linux.Conf.Au next year. Got some coding to do to add I&Q for the SDR side over the summer break.

Steve, VK2SJA, is doing to a Realistic DX-100 what I have been thinking about doing to a Heathkit HW-101. With this kind of encouragement, who could blame me for making a Minima-101? I’ve been planning on keeping the 6146s and all the final (and perhaps driver) circuitry.
Here is Steve’s very nice description of his project thus far:
