Update (3/7/12): Yesterday I prompted [email protected] for a reply, mentioning the number of pageviews this post has received. I received a prompt and polite response. I learned that I was mistaken in expecting the meter to read capacitors 1 uF or higher, since the published range of the meter is only 0.1pF-900nF. There was no explanation of why I am having problems with inductors that are within the published range of the meter. However, I was quite favorably impressed by an offer to test and fix the kit at no extra charge! I shall take them up on this offer and keep you updated.

Update (2/8/12): I am having trouble with this LC Meter. It gives me the same reading for all capacitors 1 uF or higher, and the same reading for all inductors higher than about 70 mH (this last value is just a guess): 838.8 nF and 83.88 mH, respectively. As you can see the digits are the same. It seems to work for really small capacitors and inductors, but anything bigger and these are the only readings I get. I emailed [email protected] on 1/8/12 about this, but as of 2/8/12 I have received no reply. Unless and until I learn the problem is due to some error of my own in constructing this kit, I recommend against purchasing it.

Yesterday evening I finished building the “Special Edition Accurate LC Meter Kit with Blue Backlight LCD”, available from Electronics-DIY.com for $69.95. I have no experience with such devices; a more experienced fellow told me he was impressed by its specifications, so I ordered the kit. Soldering it up was a snap. The main printed circuit-board is all through-hole construction, and the LCD-board that mounts over the top of it requires nothing but a connector.

If you want to build one of these you may want to order this version of the kit instead of the one I purchased: Accurate LC Meter Kit with Green Backlight LCD, for $59.95. My kit’s “Blue Backlight LCD” turned out to be green anyway, and I think the two kits have the same circuit, save an adjustable potentiometer on mine that controls the contrast of the LCD (which I just set to maximum anyway). Certainly the cheap case that comes with the kit I ordered is not worth the extra $10 — to use it you have to carve out a bunch of stuff (to make room for the circuit-boards), including two of the four stanchions that attach to the lid. After going to all that trouble (I used a Dremel tool) you are left with a case that requires adhesive tape to hold down one side of the lid!

The instructions that came with the kit were pretty sketchy, mostly limited to how you need to carve up the case (by the way, the measurements were wrong, so ignore them). The only thing that got me into trouble was the voltage regulator, which gets in the way of the LCD-board (and protrudes too high to seat the lid of the supplied case) if you solder it in the way you normally would (which I did!). By bending the voltage regulator out at angle I managed to get the LCD-board mounted, but the lid still won’t seat properly. Learn from my mistake, and bend the leads of the voltage regulator into a Z so that they lay flat on the board and allow the voltage regulator to sit just off the edge of the board. (Of course, this only matters if you try to use the case provided.)

You’ll need to supply your own power to this unit. There isn’t enough room in the case for a 9V battery, so I purchased a DC socket. You’ll also need to supply your own connectors for testing inductors and capacitors; the photograph on the Electronics-DIY.com website shows them in the case, but they aren’t supplied. I used banana-plug sockets. You’ll also need to supply your own pin-connectors if you use the supplied pins on the circuit-board, and you’ll need your own stand-offs if you want to support the LCD-board (only two of the four screw-holes match up with the lower PCB, but that’s probably good enough).

There is no way to select the units displayed on the screen, e.g. pF vs. nF. But the dearth of selector switches is actually one of the nice things about this unit. There is no need to select a range of capacitances or inductances. The only thing you have to do is plug it in, hit the reset button whenever you want to calibrate it, and stick in a capacitor to get a reading. If you want to test an inductor, you simply press one button to select inductance-mode, then attach your inductor. It just works — and it works with precision.

Here is a slideshow of some snapshots that I took with my cell-phone. They didn’t turn out very well, but they’re good enough to give you an idea of what it looks like. Notice that I used black electrical tape to mask the edges around the LCD. That’s because the opening I made was downright ugly. Next time I’ll try using a cutting wheel on my Dremel tool instead of a grinding tip!

I’m afraid I haven’t spend much time on the air lately, because what time I have for ham radio has been devoted to a project that began as an idea for a blog post and has grown . . . and grown . . . and grown! I hope to write it all up when everything comes together, but I don’t want to give it away just yet. For now I’ll just give you a few clues: I’ve been assembling some test equipment, including an inductance-capacitance meter kit and a signal generator kit, and I received a tantalizing shipment in the mail today from a fellow who wrote a stellar article in QST 31 years ago. Stay tuned!

On another front, I finally got to meet a local ham who is the IT manager at the hospital in our small town (population ~3K) — Mr. Andrew Rosenau, KCØYFY. I’ve been meaning to introduce myself to him ever since moving out here, but when I found out a few days ago that he is our county’s ARES (Amateur Radio Emergency Services) Emergency Coordinator, I sent him an email right away. He replied immediately, and today, after wrapping up a meeting in another part of the hospital, I ambled over and chatted with him for a few minutes in his office.

Behind him on his desk sat an HF rig, a 2M rig, and a TNC. Andy explained that he was a ham before moving here, and he got involved with ARES when the hospital became interested in EmComm. But with so few hams in our area (only 14 in the whole county), there hasn’t been much in the way of ARES activity. I volunteered to do what I could, and he said that for starters I could act as a back-up operator there at his station if he were unavailable in time of need.

It turns out that Minnesota has a huge packet network, and a radio club in a nearby town has even installed an antenna right in our city to extend this network. That was news to me! I’m going to have to dig up my old TNC and see if I can get it running. As much as I prefer CW, I have to admit that it does seem like an excellent way to handle traffic in an emergency.

ARES has always interested me. I’ve never been involved in it before, back when I lived in the Twin Cities, but now I think I owe it to my community. It appears that while there is less opportunity to do much ARES work out here in the sticks, there is also more opportunity for one ham to make a difference. So far Andy has been all alone in his effort — if even one ham chips in, that would double the number of ARES operators in our county.

Andy’s wife is a ham, too! I hope to have them over for dinner one of these days and get to know them better.

The Summits On The Air (SOTA) program was launched in Europe in 2002 but is just now making its way to the United States. Recently, there has been a surge of activity in Colorado as the program gains traction here.

The basic concept of SOTA is an award program that rewards the radio operators that activate summits and the radio operators that chase summits. For those of us that enjoy the mountains and enjoy ham radio, this is a great fit. I won’t go into all of the rules here (Warning: There Are Lots of Them), so check out the SOTA web site for the complete details.

Steve WG0AT (World Famous Alpha Goat) just published another one of his Rooster and Peanut videos that capture his recent activation of Mount Herman. I managed to work Steve on 2 Meters and I make a cameo appearance in his video below as I make my first official SOTA contact.

Steve has been activating SOTA summits for a while now and others are joining in. Here’s a video from Pikes Peak with Mike, KD9KC and Ron,WT5RZ on North American Summits On the Air weekend.

Recently, Jerry KD0BIK succumbed to the SOTA addiction, activating Mount Herman and  Green Mountain (click on the mountain names to see his blog postings). Chris NW5W has also been active…check out his web site here.

There are numerous SOTA videos on youtube from all over the world.

The SOTAWatch web site is dedicated to posting future SOTA operating plans (Alerts) and SOTA activations in progress (Spots). The North American SOTA Yahoo! Group is another great source of information.

See you on a summit soon.

For some time now I’ve been nibbling away at H. G. Wells’book, War of the Worlds — in CW! It is available along with several other books at the SKCC CW Learning Page. What a blast! It’s an effective way to improve your code speed, and it is so captivating that you want to keep coming back to it to find out what happens next. Somehow the story is all the more gripping as it unfolds slowly, letter by letter, giving you ample time to imagine the scenes that Wells describes.

Each chapter is one word-per-minute faster than the last one. So while it starts at a mere 10 WPM, if you finish the book you’ll be copying 36 WPM!

A couple other features are helpful, too. For one thing it has punctuation marks that I’ve never learned before. It’s not everyday that you hear hyphens on the air, and the first time you hear an apostrophe or quotation-mark it will throw you for a loop. But you learn them quickly enough.

Another thing I like is that Wells uses some expressions that are a bit antiquated. This helps keep you on your toes. On the air, it can be a help to anticipate the next word, but it can also be a hindrance — if you don’t hear what you expect to hear, it can take just enough milliseconds to get over the surprise that the whole word “rushes by like a freight train” (as my friend Keith describes code when it suddenly becomes opaque). By listening to War of the Worlds on CW, with its occasionally unfamiliar turns of phrase, you learn to temper your expectation so that you’re not thrown off.

All in all it’s a great way to hone your skills, and it’s way more enjoyable than the dry practice tapes I listened to ‘way back when!

Thank you to SKCC and especially to John Dunlap, KF7BYU, for making this book available!

Update: One ham has asked me for help on this. Currently the only way to listen to the files at http://www.skccgroup.com/learn/learn.php is to click on them one at a time, either listening to them one at a time online or right-clicking each one and saving them one at a time to put together in a playlist on your computer (That’s what I did, and it was a bit tedious.). If you would like to download a zipped file of the whole book, send me an email at [email protected] and I’ll give you the link for as long as I can spare the disk space to keep the zipped file online.

Tonight I made my first digital-mode contact! Using PSK-31, I worked special event station VE3FRST (“UN International Year of Forests”) on 40 meters. Michael, VE3NOO, kindly emailed me this screenshot of the moment:

A few things had me fumbling around, but over the next few contacts I started to get the hang of it. After VE3FRST I went on to work another station in Ontario, one in Alabama, and one in France with PSK-31 before retreating to my key and working Costa Rica with CW.

I highly recommend the DigiMaster PRO PLUS! It comes with a USB soundcard and was very easy to hook up and get going with Ham Radio Deluxe/Digital Master 780. It performs both as a CAT interface and as a data interface, and works great.

I learned the hard way that not all CAT cables are worth buying. Buy cheap, and you’ll buy twice like I did. My first one was a cheap cable from “affordableradio” on ebay. It uses the Prolific chipset for the serial-to-USB interface. Stay away from Prolific! The only thing prolific about it was the prolific number of spontaneous disconnections and “Blue Screen of Death” crashes. I tried everything — every driver I could get my hands on, I/O buffer adjustments, etc. but it was junk. I couldn’t bring myself to sell it to another ham, so I returned it. No refund yet, but here’s hoping.

If you’re just getting started with CW, you need to know that learning Morse Code is only part of the puzzle. You’ll also need to learn basic CW Operating Procedures, and you’ll need to know some commonly used abbreviations, too. It wouldn’t be a bad idea to print out something like this and keep it near your key until sending and receiving these are second-nature:

Recently on Google Plus there was a discussion of what qualifies as a separate country in the amateur radio world. The confusion point was that Alaska was showing up in logging software as a “country”. It turns out is is both a country and a state.

The generally accepted countries list is established by the DXCC award. Actually, the correct term is entities, not countries, but in normal conversation people seem to use countries. DXCC stands for DX Century Club, with the minimum award being 100 (Century) countries.

Back to the issue of Alaska — it clearly is one of the 50 United States, so you’ll need to work it to achieve Worked All States (WAS). It is geographically separated from the lower 48 states, so it is also considered a separate country. The same is true for Hawaii — counts as a state and a country.

To find out what counts as a country, you need to study the DXCC Country List. A peek at this list reveals that these US possessions are all considered separate countries for DXCC purposes:

K,W,N, AA-AK#  United States of America
KG4# Guantanamo Bay
KH0# Mariana Is.
KH1# Baker & Howland Is.
KH2#* Guam
KH3#* Johnston I.
KH4# Midway I.
KH5# Palmyra & Jarvis Is.
KH5K# Kingman Reef
KH6,7#* Hawaii
KH7K# Kure I.
KH8#* American Samoa
KH8#* Swains I.
KH9# Wake I.
KL,AL,NL, WL#* Alaska
KP1# Navassa I.
KP2#* Virgin Is.
KP3,4#* Puerto Rico
KP5# Desecheo I.

So there are 19 countries, just inside US territory.

The DXCC Rules that define a country are complex, a mix of geographical and political considerations. I won’t even try to explain it here. Be aware that as the political boundaries change, countries can be added or deleted from the list.
