CB interlopers

Propagation remains good on 10 metres. I left the K3 on 28.076 running JT65-HF for most of the day. I made several contacts including N3CAL, WA2CRB, PY8ELO, KE1AF, WB9OTX, WK8G and SV4FFK. The map shows where my signal was heard. I was even spotted by Joe, W6CQZ/4, the author of the excellent JT65-HF software.

JT65 is addictive. It’s also a very relaxing way to make QSOs. It’s ideal for me at the moment because my eyes tire very easily. I end up with blurred or double vision if I read or stare at the computer screen for too long so modes like PSK31 aren’t really a good idea. Thanks to the JT65-HF add-on JT-Alert an alarm sounds if a station I haven’t worked before calls CQ and another sound wakes me up if a station replies to me. This means that I can look out the window or something and only need look at the screen when I have something to do. The print in the JT65-HF program window is nice and big too.

Listening on 28.076 I heard some strange noises which I eventually realized were FM transmissions being received in SSB mode. CBers transmitting out of band I presume.

I don’t suppose many CBers read this blog but come on, guys. It’s none of my business if you choose to operate illegally but if you do, please stay below 28MHz. You may not hear our weak JT65 signals with your FM radios but we sure as hell can hear you.

Update: Just worked Joe “The Man” W6CQZ/4 in Florida. He was running 5W to what I seem to remember him posting once in the JT65-HF Google group is a Hamstick on a mag mount stuck to the roof of his shed. Thank you Joe for the contact and for the fantastic JT65-HF software!

Steve Jobs: His Legacy

6 October 2011 | by Rich KB2MOB | Leave a Comment (0)

If you’re wondering why I am posting this instead of an Amateur Radio story, then please read the full article and you will understand. But for now, I am posting a clip and a link to my full article on the Q103Albany website, and it has already been picked up by the station I used to work at in Utica as well. Here is a clip:

I have been trying to write this story for hours now. It’s not hard to talk about someone like Steve Jobs and recite facts about him. Yes, he pioneered how we consume digital content and how we buy our digital music as well as how we use computers and much more. And while it could be considered corny by some for me to say this, he touched lives all over the world. Just look at Twitter and Facebook. One of those lives he touched, is mine.

To read the full article, check out my Tech Thursday story for today.

Handiham World for 05 October 2011

5 October 2011 | by Patrick WA0TDA | Leave a Comment (1)

Welcome to Handiham World.

A broken water pipe gets me thinking…

What sort of things might cause a disaster in my ham radio shack? I started thinking about this recently after dealing with a minor disaster caused by a leaking water pipe in the ceiling of the basement. As usual, I was sitting in my home office, which also serves as my ham shack, when I heard a faint drip, drip, drip. Since I spend an awful lot of time in my office, I know and recognize all of the usual sounds of the house around me. In fact, I don’t really notice if the compressor in the freezer comes on and my brain rarely even registers sound of the washing machine or dryer in the adjacent laundry room. The furnace or air conditioner can come on and go off without interrupting me. Jasper, my dog, wanders the house and occasionally growls at a squirrel that he sees through the window. None of this stuff bothers me or particularly gets my attention. But the brain is a marvelous thing; it can ignore the common and expected while immediately picking up on something unusual.

The sound of dripping water, even though barely audible, got my attention!

Sure enough, an inspection of the recreation room around the corner from my office revealed a drip from the ceiling. Several of the tiles in the suspended ceiling had gotten waterlogged and collapsed onto the floor, and I hadn’t heard that sound because I had only just a few minutes before come into the office to sit down and do some more work. The leak must have occurred in the afternoon shortly after I had finished my usual office day and had taken the dog out for a walk. When I returned to the office after dinner, that’s when I heard the dripping sound that was so out of place. It turns out that a 90° copper connecting joint in the cold water pipe going to the outdoor irrigation system developed a tiny pinhole leak on the inside of the bend. The tiny, almost invisible spray was enough to create quite a mess given a few hours. The soaked ceiling tiles collapsed onto an easy chair, soaking it and ruining the cushion. The carpet on the floor was soaked in an area of about a yard square. A few other items stored in the room got wet on the outside, but were not ruined because I heard the drip and responded in time to shut off the water. Fortunately, we have a carpet cleaning machine that vacuums up water and we had a spare cushion for the chair. I haven’t replaced the ceiling tiles yet, but they are standard 2′ x 2′ squares that are commonly available at any big box building store. As we are so fond of saying in Minnesota, “it could’ve been worse!”

Of course I called the plumber, and he was able to fix the problem the next day. Fortunately, we have a shut off valve for that particular leg of the water system in our house, so there was no need to keep the main valve turned off. It’s heck to be without water when you need to wash, cook, and flush! But what got me to thinking about the ham shack in relation to this broken pipe was that the shutoff valve is located directly above the ceiling in my office. In fact, several water pipes converge in the ceiling above the ham shack and it is sobering to think that the copper pipe carrying all of that water is exactly the same age as the pipe fitting that failed in the next room, which is about 20 years old. So, as I sit here talking into the microphone and enjoying a nice session on my radio, will I one day feel a drip, drip, drip on my head? I guess it could happen, and I have to admit that when I finished the basement and built the ham shack I never gave a second thought to the water pipes running through the ceiling joists overhead. I had grown up with copper water pipe in my parents’ house, and I cannot remember a single time that there had ever been a leak. I guess I would not have been too surprised if a leak had occurred where pipes were joined in the soldered connection, but to have a piece of copper simply spring a leak in the body of the pipe? It did seem pretty unlikely, but like all such things it is not something to worry about unless it happens to you – and it happened to me!

So I am forced to assess the probability of another leak, perhaps occurring over the critical electronic and computing equipment I have in the ham shack. Some of this equipment runs for hours or days at a time without being turned off. One can only imagine the damage that would be caused by water pouring onto the energized equipment. When I wired the ham shack, everything was put on ground fault interrupters. Given a good soaking, the equipment would probably short and trip the interrupters, but by then of course the station and computers would be ruined. This is not something I care to think about, but it is nonetheless a possibility. I had considered the possibility of a leak like the one we had to be extremely remote, and perhaps I was right. Nonetheless, had the leak occurred over the ham shack it would’ve meant many thousands of dollars of damage instead of a soaked chair cushion and a few feet of wet carpet.

What to do? Well, moving the ham shack and home office would be a major undertaking and a huge disruption in my work schedule. It wouldn’t be impossible, but it would be expensive and difficult. For now, the best I can do is to turn the main water valve for the entire house to the “off” position whenever we leave on vacation or for any kind of extended multi-day trip. This is something I have always done anyway, and while it is not a perfect solution, it does prevent damage from leaks that might occur when no one is home and when damage can be severe due to the fact that no one is around to discover the leak. Long ago, when I worked in an appliance store, we recommended that our customers who were leaving on vacation turn off the water supply to their washing machines because the hoses that fed the washing machine might burst and cause flooding in the basement. Turning off the whole house valve takes care of that problem. Keeping equipment off the floor is another good idea.

We are used to thinking about protecting our amateur radio equipment and its associated computer equipment from lightning damage, but we cannot ignore the threat posed by water!

For Handiham World, I’m…

Meeting old and new radioamateurs

5 October 2011 | by Bas PE4BAS | Leave a Comment (1)

Dragonfly photographed in our garden in the evening sun

The weather was beautifull the last 2 weeks. Temperatures around 20-24 C without that much wind, a real nice autumn. Unfortenately work had to be done both at the job and at home. Not much time for radio, although… at monday I heard a few locals on 10m. They seem to have a kind of net there on 28.400 USB. I heard some known voices and decided to jump in. After a short hello I discovered a couple of them were old friends from the CB years. I did a lot of 11 Mtr DX about 20 years ago with one of them and now he got his license as PD1BM. I remember Bert very well as we did a lot of DX together, I even visited him now and then after school back then just to do some DX. Bert has a ear for special DX and also has a exceptional location between 2 large canals which apparently gives him a advantage. I welcome him on the amateurbands and hope he enjoys it a lot. Bert already made some very nice DX with his 4 element LFA yagi for 10 Mtr. Last friday we had a meeting from our radioclub VERON dep. Hunsingo, there was a pile of QSL cards waiting for me. Another pile was for a neigbour HAM PC5F which I had to deliver to another local HAM. Very complicated….end of the story he made a telephone call to me and met me at my job to get his cards. Never spoke this guy although he is living in the same street that was my QTH for 12 years. So, I decided to e-mail him for a sked. We did meet at 80m PSK31 at Tuesday evening and had a chat for a while. PC5F Ferdinand has all his antennas inside the house on the attic, and makes some very nice DX for instance to North America on 10m! And with Hawaii on 20m! That is really nice, why do we need all those big antennas??
