Hi Bill,
I discovered SolderSmoke a few years ago by listening to another pod
cast. Ever since, I have been hooked on this podcast and listen to it
whenever I have time. I have finally caught up and finished episode
142 today. I love the enthusiasm and spirit of discovery and creation
that goes into the stories in SS.
The first time I heard about amateur radio was in high school. It
seemed to be a overly nerdy thing at the time and I wasn’t sure what
it was. However, after I started listening to SS, I discovered that
this is something that I wanted to do. So, on New Years Eve with the
kind help of a local examiner (Ori, VA3XW), I wrote my basic and
advanced exam and passed with honours. In Canada, we only have 3
categories: basic, advanced and morse code. I am very excited about
this and I am glad that SS made me make the jump.
You know, every time the word knack comes up, it is portrayed in a
negative way. Someone is “afflicted” with the knack or shows knackish
“symptoms” as if it was a horrible disease. I would like to change
this perspective.
I hereby declare myself blessed with the knack. Ever since I was a kid,
I disassembled various electronics around the house (to the dismay of
my parents). I knew when I was doing something right when I could put
something back together and it worked, or later, it worked better than
before. Despite my parents’ persuasion to pursue other branches of
non-technical studies, I made up my mind to study electrical
engineering (must have been a teenage rebellion thing). Nonetheless
I finished school and found a job doing electronics design which I
love. Some of the people that you meet in this field are just
phenomenal. It has been a good career decision and I think it is truly
amazing. Thus, I see the knack as being a gift which I was fortunate
enough to hold.
I think one of the most important aspect of the knack is the desire to
understand and have self reliance on what we use on a daily basis. I
repair my own bikes and I’ve never bought a ready made computer.
Having a home machine shop greatly helps in this regard too. My first
oscilloscope I designed and built myself:
http://yyao.ca/projects/oscilloscope/
I have also resolved to build my first rig instead of buying one.
However, work is really busy these days, and it doesn’t look like I
will be able to do this soon. One of these days, I will construct my
own rig and wiggle the ether.
I am currently visiting Silicon Valley here in California. There is
much to visit and do here. For example, the De Anza Flea Market
happens every 2nd Saturday (which is my first introduction to a swap
meet):
http://www.electronicsfleamarket.com/
The Computer History Museum is amazing:
http://www.computerhistory.org/
For a limited time, you can see Jim William’s work bench at the
museum. If you thought your workbench was messy, you haven’t seen
anything:

Now, imagine having the world’s most smartest electronics engineers
having dinner together. That’s what the Analog Aficionados Party is about:
http://www.edn.com/blog/Anablog/41523-Analog_Aficionados_party_Feb_18_2012.php
On top of that, there are a lot of trade shows which you can go to
check out the latest and greatest of test equipment. They don’t have
the same feel as some of my analog oscilloscopes, but they are shiny.
As you can see, this is a paradise for anyone blessed with the knack.
Anyhow, this email is long enough and I hope your eyes haven’t glazed
over yet. My best regards to you, Billy, Maria and your wife.
73,
Yi Yao

Hiccups in SolderSmoke 139
First there was the whistling of my SSS sounds (a speech defect that I had been blissfully unaware of due to a nullifying case of tinnitus!) Then, in SolderSmoke 139 the long-suffering SolderSmoke listeners had to put up with hiccups. Yea, around 53 minutes into the show there began an annoying series of hiccups. Being an essentially analog kind of guy, I’m sort of pleased to point out that these are DIGITAL hiccups, apparently introduced by the Audacity software during the actual recording (not when I converted the show to mp3). I’ve been having more than my normal share of road-kill computer problems lately. The laptop I’m using to record the show ate a couple of the recent episodes before I had a chance to upload them (I had to do them over — that’s very frustrating). So this time I was recording the show on a thumb drive. Apparently it was filling up as we got close to the end, which led to the hiccups. The worst part was that a hiccup came just as I was delivering a key quote from The Woz. (I’ll post it.)
If anyone has any gear laying around that might with these problems, please send it my way. Obviously I could use a bigger thumb drive. An external sound card might be nice. I could probably use another laptop also…

The Picture You Heard in SS 136 — FROM SPAAAACE!
In the last podcast I played a recording of some 2 meter signals picked up by my handheld transceiver from the new amateur radio satellite ArisSat-1. Included in the transmission were some tones that were obviously SSTV. Mike, K2MTS, ran the audio through some SSTV software and got this! Pretty good! From space to my HT, across the room to the SolderSmoke mic, out over the internet in podcast form, back to me in an e-mail, and now, on the blog. Thanks Mike!

I’m still enjoying your podcast very much – I have the T-shirt to prove it!
My parents bought me SolderSmoke the book for Christmas and I must echo other people’s comments that it is very good and the explanations you give make a lot more sense than those in other technical publications.
Listening to your podcast got me thinking about radios again and I have nearly completed my first homebrewed transceiver project. It’s all YOUR fault! I had a spare RockMite keyer chip in my junk box, so I thought I’d use it……….. Take one small keyer chip and……… build a whole new radio!
Okay, I used Dave’s (K1SWL) schematic, but I did not use any printed circuit boards and I have made some modifications to the circuit. I think I can class this as homebrew. I even made the twin paddle key! The only thing I didn’t make from parts are the earphones, see http://www.flickr.com/photos/24901892@N03/5833428467/ There are more photos on the Flickr site too.
Looking forward to the next edition of the SolderSmoke podcast.

From the good folks at Sierra Radio (our sponsor):
Want to learn to design and program with microcontrollers?
Want to add “smarts” to your next ham radio project?
Whether you are new to microcontrollers or an experienced designer / programmer, the HamStack is a great platform for your next project. Based on the Microchip PIC architecture, the HamStack can be programmed in C or Basic.
Many people ask us how to choose the best hardware and software tools for developing ham radio projects with microcontrollers.
Up to now, there really has not been a great answer to that question.
So, in traditional ham radio fashion, we put a system together. We call it a HamStack.
The HamStack platform combines popular PIC microcontrollers, a set of circuit boards, great C and Basic language compilers, in-

Podcast QRM Culprit Found: WBIG-FM 100.3 MHz
Listeners noticed that recent SolderSmoke podcasts had some other audio playing faintly in the background. At first I though this must have been AM broadcast band breakthrough, so I built a little crystal radio, only to discover that the powerful AM stations here were not playing the ZZ-Top style classic rock that I was hearing in background noise. Bert, WF7I, suggested that I listen carefully to the QRM for a call sign. I tried that this morning. I couldn’t get a clear call sign, but I picked up the unmistakable rhythm of Peter Frampton’s “Do You Feel Like We Do?” Fortunately that song is 1) infrequently played and 2) quite long; I had enough time to take a spin around the FM radio dial. Sure enough, I caught the tail end of the Frampton song on WBIG-FM 100.3 A quick check of the web shows that this is a 50,000 watt station that has its transmitter within about 1 kilometer of my house. Bingo.
The mic cord is just about 1/2 wavelength. That would put the high voltage nodes at the ends, right? I notice that the interference drops noticeably if I wind up the cord, and increases a lot if I stretch out the cord.
I can hear some other stations in there also (one country station). It may be that there are multiple FM stations broadcasting from that antenna site. I can see the tower’s red lights blinking from my front lawn.
Thank you Peter Frampton!
