Handiham World for 25 November 2009

Welcome to Handiham World!

Handiham Headquarters will be closed for the United States Thanksgiving holiday

Handiham Headquarters will be closed for the United States Thanksgiving holiday on Thursday and Friday, November 26-27, 2009. An audio lecture notification will be sent out early, on Wednesday instead of Friday.

By the way, what do you have to be thankful for? Here is my list of ham radio stuff, in no particular order:

I am thankful for…

  • Antennas that stay up & keep working through the entire Minnesota winter. (You haven’t experienced real cold until you’ve handled aluminum tubing or scaled a tower in January up here on the frozen tundra.)
  • ARRL. I couldn’t get along without my [email protected] address and monthly QST, but I can also rest easy knowing that the League is our advocate on so many fronts.
  • The way most ham radio gear keeps working year after year, reliably delivering good service, when consumer-grade electronics have long since given up the ghost.
  • Repeater owners who welcome activity on their machines.
  • Echolink, IRLP, and WIRES.
  • The Internet and all of the ham radio applications it makes possible.
  • Hams who design circuits or write software for the rest of us.
  • Elmers who help newbies and oldbies (Is that a real word?)
  • Solar cycle 24. Better late than never.
  • Nets. I love the way we can stay connected in our “virtual communities” on the air.
  • Our Handiham members, be they regular members, supporters, or volunteers. Talk about communities – they are the best!
  • Radio clubs. Sometimes you need to just meet other hams face to face.
  • The manufacturers and dealers who work so hard to make amateur radio technology available to us.
  • People who step up to the plate to teach ham radio classes. They are responsible for keeping amateur radio healthy by training new operators.
  • Anyone who funds, plans, or goes on a DXpedition. What these folks do for amateur radio really pushes the limits, and if you don’t believe me, take a look at some of the DXpedition videos.
  • Volunteer examiners and their VECs. Having had to travel long distances to take most of my exams at FCC offices, I really appreciate the volunteers who offer convenient, friendly, local exam sessions, giving freely of their own time and talent to help others become hams for the first time or to step up the ladder to General or Extra.
  • Contest planners, QSL managers, people who serve on committees, hamfest organizers, authors, publishers, and all of the others who work behind the scenes to enrich our radio experiences.
  • DSP. Good grief, how could we stand all of that noise we used to endure before ClearSpeech speakers and the digital signal processing now standard in every transceiver?
  • Anyone brave and patient enough to be a net control station.
  • My understanding family, including my XYL, Susie, who encourages me to “get on the air” or “give that guy a call” when we hear someone calling on a repeater as we travel in the car, my son Will, KC0LJL, who writes software for me, and my dog Jasper, who keeps me company in the ham shack.
  • And all of my ham radio friends! Without real people, ham radio would just be a bunch of stuff. Now, don’t get me wrong; I like all of the equipment and gadgetry, but what really makes ham radio special for me is… YOU!

For Handiham World, I’m…

Waiting for Baudot

I just submitted my meager log from last weekend’s WAE RTTY test — just 45 QSOs and a whopping claimed score of 1,530. I only operated for a few morning hours (between 1125-1345 on Saturday and 1245-1700 on Sunday) in order to give DM780 a try at good ol’ fashioned 170/45 Baudot, a mode I haven’t worked since days of yore with the trusty old KAM and a terminal program. High time to give the new technologies a try, said I.

Some random thoughts and observations about RTTY operation with the K3 and DM780 follow…
The DM780 + HRD Logbook combination did fairly well, considering HB9DRV himself says “HRD/DM780 is not contest software.” As such, there is no easy provision for sending or receiving QTC info for extra multipliers, and it wasn’t clear at first how to get DM780 to increment serial numbers in the exchange field (put them in [brackets], I finally discovered). Using a fresh database file for the log (as I do for every contest) lets me use the logbook’s Awards Tracking and Worked Status functions to keep an eye on what stations and countries I’ve worked on each band, but I have to be careful to individually set the other databases (previous contest logs, plus my master logbook) to not figure into the worked status lookups (this is one in the Logbook Databases control panel).
Another limitation from a contesting perspective is HRD Logbook’s inability to output Cabrillo files for log submission after the test, a feature that was available in HRD v4. So I have to use another app (SP7DQR’S nice ADIF2CABR freeware app) to convert an ADIF export file into Cabrillo format, and that only after doing a search-and-replace on the ADIF file to change the tag to that the conversion app is looking for. No biggie, I mud-wrestle data for a living, so this is just another day at the office…
That said… I’m familiar and comfortable with DM780 and HRD Logbook so it all worked just fine for me.
I worked the first day with the K3 in DATA A mode before remembering that AFSK A mode allows DUAL PB filtering to peak the mark and space tones. The DM780 waterfall screenshots below illustrate the difference far better than words:
K3 set to DATA A mode. BW = 400 Hz, Fc = 1530 Hz

K3 set to AFSK A mode. BW = 400 Hz, Fc = 1530 Hz, DUAL PB enabled
Note that the overall bandwidth in AFSK A mode is quite a bit narrower, even though in both cases the K3 was set to 400 Hz, and the distinct notch between mark and space tones is indicative of how effective this filtering mode works. Back in the pre-DSP days with the TS-930S and JST-135/245 transceivers and NRD-525/535 receivers, I used to use a Datong FL-3 audio filter which had a RTTY mode that accomplished the same thing, albeit at the AF stage.
DATA A and AFSK A each have their advantages. In DATA A (or AFSK A with DUAL PB turned off), I can open the bandwidth up and see a good portion of the band (I generally set DM780 to display 3 kHz on the waterfall and set the K3 bandwidth to match) and all the signals on the air, then select the desired signals with a point-and-click like I do in PSK31 mode. If QRM is a problem, I can crank down the bandwidth and shift the passband center frequency to pass only the station I’m working; once the QSO is complete, a quick tap-twist of the K3’s shift control recalls my wide settings and I’m back on the hunt. I rarely touch the VFO dial, all tuning is done with the mouse.
In AFSK A mode with DUAL PB enabled, however, the K3’s center frequency is fixed at 1530 Hz so all tuning must be done with the VFO. Also, the bandwidth is limited to 500 Hz max (which as shown in the image above is a bit less in practice, more like 250 Hz or so) making VFO tuning very touchy and slow (the 1 Hz fine steps must be used) and renders the waterfall useless for spotting other signals. But the filtering advantage is huge, especially in a contest scenario.
For me, it’s a no brainer — in the latter stages of the WAE contest I found myself using DUAL PB almost exclusively, occasionally switching it off and opening up the bandwidth if the band was quiet or if I’ve already worked the majority of the stations I tune across, since clicking on a waterfall makes it far easier to hunt and pounce.
DM780 facilitates the switch from narrow DUAL PB to wideband waterfall tuning easily: I first activate the center frequency marker (Tools>Program Options>Waterfall menu, or F8) and set it to match the K3 DUAL PB center frequency (1530 Hz). After finding a signal on the waterfall and clicking on it, I can then click the C button just above the waterfall to center it at 1530 Hz (HRD offsets the K3 VFO frequency to do this), and then activate the DUAL PB (press/hold the #6 key on the K3 keypad). The bandwidth is narrowed to 500 Hz, and the mark and space tones are perfectly positioned for decoding. To switch back to wideband, press/hold DUAL PB, and tap XFIL a couple of times to select the 2.7 kHz filter or use one of the filter presets to select my standard wide data setting of 3 kHz. This can perhaps be simplified to a one-button process using the new macro feature Elecraft just added to the latest firmware version; I need to check into that…
Note to K3 users: when working RTTY in AFSK A mode, either the radio or DM780 needs to be set to reverse, as AFSK A demodulates the lower sideband while DM780 looks for the upper. DATA A, however, works in the upper sideband.

Handiham World for 18 November 2009

Welcome to Handiham World!

Matt in the bucket truck lift

Don had just completed some work on Matt’s 220 MHz antennas, and Matt was headed up to do the final inspection.

It’s always a good idea to get your antenna work done before winter, especially if you live in Minnesota, as Matt, KA0PQW does. One may be blind, but that doesn’t mean you can’t do antenna work. Matt directs and does hands-on work on his antenna projects, and has some great helpers.

I have always recommended having at least one helper available for any antenna project that involves working on an elevated antenna system, whether it is on a roof or high on a tower. The reason, of course, is safety – if something goes wrong, the second person can provide assistance or call for help. Besides, most of these projects really do require at least one more set of hands – and eyes. You can use a spotter to check for hazards like power lines and buried pipes or cables. This goes for any ham radio operator, whether they are blind or sighted. I shudder to think of all the times I have not followed my own advice, but in my defense I was young and stupid. As a teenager, I navigated our family home’s rooftop like a monkey – stringing antennas, hurrying down to test for SWR, then running back up the ladder to the roof to make adjustments – all without anyone else around. When I bought a used tower, I was up and down that thing dozens and dozens of times. I did buy a Klein lineman’s belt but even so, I worked alone all too often. The closest call I ever had was on an old telescoping mast. I had just finished my antenna work and stepped onto the ground when the steel cable holding the top section snapped and the tower telescoped back down. A few seconds delay in getting off would have meant amputated fingers and toes! Worse yet, I did not have a helper around.

Well, I have learned a lot since then. I ask for help, so that I have someone there to do antenna work as well as to help us both stay safe. I plan to stay safe – and you know what? Staying safe means more happy years of ham radio fun!

LHS Episode #027: Where Are My Meds?

haarpWe have topped 40,000 downloads! Thanks go out to all of our listeners and live webcast attendees for making Linux in the HAM Shack as popular as it is. Give yourselves a huge round of applause. We're also well on our way to our donation goal of $750 so we can buy booth space and Internet access at the Dayton Hamvention in Dayton, Ohio, in May of 2010. Thank you for all of your donations. Please keep them coming as you're able to send them in!

In this episode, we address listener feedback and comments, and then in a burst of inspiration invite listeners from the chat room to come onto the program for a lively and very fun roundtable discussion. Topics were varied, from portable antenna design, to life without Red Bull; from the HAARP VLF array in Alaska to D-STAR, PACTOR and other digital ham radio communication modes. And since I was on meds and Richard was off his, things got a little crazy towards the end.

We hope you enjoy this episode of Linux in the HAM Shack. Please leave us comments or questions on the web site or via voice mail at 888-455-0305. And send your best wishes to Bill, KA9WKA, who has taken on the responsibility of getting LHS's show notes out in a timely fashion. Thanks, Bill. You're a lifesaver!

CQ WWDX SSB 1996: Lost Log Discovered!

Almost as much fun as finding a $20 bill in an old coat is finding an old contest log on an even older hard drive! Today I discovered my log data from the 1996 CQ WWDX SSB contest, which I must have exported from Log Windows before my erstwhile Toshiba laptop screwed the pooch back in the late 90’s.
After some data mud wrestling, I was able to convert to ADIF and import into HRD and saw my total DXCC worked count jump from 119 to 123 (the “new” ones are 3DA Swaziland; FS Saint Martin; V4 St. Kitts & Nevis; and GU Guernsey).
I then uploaded the new QSOs to LoTW and immediately had 13 new QSLs credited to my account, with a handful of new DXCC/bands confirmed: VP5 Turks & Caicos (80m); P4 Aruba (15m); 8P Barbados (15m); V2 Antigua & Barbuda (15m & 20m); and GI Northern Ireland (20m) — the latter two being all-time new ones confirmed, bringing my DXCC confirmed count to 80, and DXCC Challenge totals to 239 worked/123 confirmed.
God only knows how many of my other contest logs are gone forever — I must have worked at least another dozen contests back around that time, and all these logs got nuked along with the Toshiba. This is why I now keep separate paper logs as backup.
Also found this photo of the old N2HIE shack in Closter, New Jersey circa 1998.
Complete with that utterly dreadful JRC NVT-56 desk mic. Wish I held onto that, seeing how one just sold for over $1,300 on eBay. Please, stop laughing… I’m not kidding:
WTF is wrong with people? Clearly some hams have more money than sense…

Handiham World for 11 November 2009

Welcome to Handiham World!

The move, part 2

Avery's old office undergoing renovation
Image: Avery’s old office area showing one of our five big file cabinets that still needs to be moved.

We continue this week with our office move, this time moving Nancy’s office and the file cabinets. This is a big part of the move, and will likely cause some disruption in our regular work schedule. We ask for your patience, as phone calls and emails may take a bit longer to answer. I am still working on a solution for our telephone system, but for now all of my phone calls go directly to voice mail. As calls come in, I am notified of messages left on voice mail through an email message, so that I am able to return calls fairly quickly. Nancy is in the office today, but is using a cubicle in the hallway.

The movers will pick up the file cabinets and some other equipment on Thursday, November 12. Nancy plans to be in the office that day to make sure that all of the files and equipment are accounted for, while I will be waiting at Camp Courage to meet the movers and direct the placement of the five large horizontal file cabinets and the other furniture and equipment in our new office. Depending on my schedule for that day, I do still plan to check in to the regional PICONET on 3.925 MHz at 09:00 CST and the Handiham Echolink net at 11:00 CST. We still need to upgrade the antenna systems, so I will be limited to checking in to one or both nets via the Internet. I will try to contact Lyle, K0LR, our volunteer who maintains the Handiham Remote Base, when he runs the PICONET as the regular Thursday morning net control station.

We are still looking at more moving in the near future, too. Because we will be out at Camp Courage, we have decided that it is best to move our equipment storage and test gear out to camp. This means that the Handiham repair shop at Courage Center will close and make the move, though not immediately. I will enlist the help of some volunteers to make sure that the equipment is moved properly. While this decision means more work in the short term, I think we will benefit by having everything right where we need it. It does present a problem when people bring donations of radio gear to the Courage Center, but we think we can simply have the gear set aside for pick up and transport to Camp Courage as needed. We do plan to continue the equipment loan program when we get organized again, with donated gear first being distributed to our campers who need stations and accessories at the upcoming Handiham Radio Camp in late May, 2010.

Since our shop volunteers were all from the Twin Cities area, we will be on the lookout for hams who live close to our new location and who want to volunteer to check out donated ham radio equipment before it is distributed to our members. It should be noted that we do not repair the equipment anymore, as we did years ago. We check it to make sure that it is in working condition. Only the most minor repairs are possible these days, because the equipment is full of surface-mount devices and repairs are generally done by a well-equipped commercial repair facility that has access to modern instruments and a stock of replacement circuit boards. The old method of using basic test gear to track down faults to the component level is just not practical with the newer equipment.

So there is a lot to work out. We are making great progress, but there is more to do. We are rolling up our sleeves and getting right to work!
