Any Guesses?
Guess the rude noise on 6m I recorded a little while ago but forgot all about

Updated RTL1090 – more planes on your SDR based virtual radar
A few days ago, I noticed some mention about a new version of the RTL1090 program. This is Windows software which you can run on your PC in conjunction with the RTL-SDR dongles and plot ADS-B transmissions from aircraft. For a bit more detail, please see my earlier blog post
Yesterday evening I downloaded the program and installed it, which was straightforward. My first impression was that I was seeing more aircraft than I had before. With the small antenna provided with the dongle on the desk in front of me, I was seeing aircraft further out than I had done before with the RTL1090 software. Testing again this morning, the same seems true.
As well as seemingly being a bit more sensitive, the new version of the RTL1090 software provides a bit more information in the List view abut messages which have been decoded, which might be useful or interesting (or encouraging) if you have not yet got the link to a plotting program working yet.
Download the new version of RTL1090 here
The other thing that looks quite interesting is that the team have produced a program to interface with RTL1090 and plot aircraft on a map. It’s called Globe-S and can be found here – I haven’t yet installed it, but it looks a nice interface.

Where did the Stations Go ?
The DX seems to have disappeared here in the valley; it left just a mysteriously as it came. There didn’t appear to be any reason why I captured it, in the first place, around the first of the year, and there doesn’t seem to be any reason it left; but I’m hearing very little here in the valley.
Just as a precaution, I’ve submitted a work order (I’m not holding my breath) for a “new” Gold coating of on the West Virginia State Capitol Dome, which is just up the street. It seems only logical that the recent thunderstorms and a tremendous lightening strike (point blank) last week, on the dome, has reduced my DX to a trickle. I’m just not getting the usual radio signal “bounce” off all that gold.
All kidding aside; the weather has been terrible for the last few weeks. I think the same can be said about most of the European stations which I usually work. They seem to be underwater for the most part. I saw on the news this morning where Calgary Canada has been flooded. The mid west here in the US is still experiencing severe thunderstorms on a daily basis. I think we’re all in trouble with these shifting, and unusual weather patterns in the world.
Perhaps, in some unusual way, I’ll experience these unusual DX band conditions again next year at the same time? It’s beginning to sound like my DX contacts are somewhat of a fluke now, which is difficult to explain. I’ll be looking forward to the beginning of next year, to see if these conditions repeat themselves.

FUNcube Dongle
I’ve been spending a few hours playing around with a FUNcube Dongle Pro. There was a lot of excitement about this project a couple of years ago when it started. In order to get one you had to be quick off the mark on Ebay. I never succeeded, then I got ill and then I forgot about it. This one was passed on to me by a friend who successfully purchased one but never used it.
I started off by following the instructions in the user manual. I followed this by installing and setting up a complicated-looking SDR program called Spectravue. I was baffled by most of this program’s settings and I wasn’t sure if it worked.
What I should have done was try some of the SDR programs I installed when I was playing about with USB TV dongles at the beginning of the year. I started SDR#, selected the FUNcube Dongle from a pull-down list, clicked Start and it just worked!
Simon Brown’s SDR-Radio worked as well, and with equal ease, though as luck would have it I tried it on the very day that the (free) licence key for the program expired. This appeared to come as much of a surprise to Simon as everyone else. As I type, Simon has just uploaded a fix which I have yet to install.
I thought I would try using the FCD as an ADS-B receiver which I did with the TV dongles but I soon discovered that I can’t. The FCD looks like a budget USB sound card to the SDR software, so its bandwidth is restricted to 2 x 48kHz. The digital TV dongles can transfer a much wider bandwidth. This is noticeable if you try to receive Band 2 FM radio – through the FCD the signal sounds distorted on peaks because the bandwidth isn’t quite wide enough for FM stereo which needs a full 100kHz..
It will be interesting to use the dongle with the FUNcube 1 satellite when it gets off the ground later this year (we hope!) In the meantime I’ll use it to watch for Sporadic-E in the VHF band.

Peoples is crazy!
When I was a kid, I vaguely remember a comedian on TV, who would say in a thick, mock German accent, “Peoples is crazy!” or something very similar to that. That line kept running through my mind tonight as I volunteered as a CERT member for South Plainfield Emergency Management at the South Plainfield High School graduation ceremony, held at the football field.
We provided a whole bunch of services. We directed people to parking spots, and as it was a hot day – we handed out cold bottled water to anyone who desired it, we provided “a presence” and kept our eyes peeled for anyone who looked like they might get ill or faint, or might otherwise need assistance.
By the end of the ceremony, 260 high school grads received their diplomas after many speeches, much cheering and screaming and hoopla.
The best came at the end of the night, though, as dusk was falling and the near full moon started to rise. On three separate occasions, I kept spectators from jumping over the chain link fence and running onto the football field to greet their graduates. In each case, I’m not talking about kids here. I am referring to older “Dad types” who should have known better than to attempt such a stunt. On each occasion, as the improbable was about to be tried, I simply but firmly stated, “Please go around to the gate and don’t jump over the fence.” The first two guys said nothing – and just complied.
The third guy? Oh, he was a good one. A rather snarky “And why should I listen to you?” was what I got for my request. Rather than argue, I just very politely asked, “Sir, do you really want your son or daughter to remember their high school graduation night as the time that Dad had to go to the Emergency Room to get stitches in his leg after he cut it while trying to jump the football field fence?” He looked at me, thought about it for half a second and went around to the gate.

QRP – When you care to send the very least!
Follow up – Saw my fence jumper today at the A&P – yep, the third guy. While I was shopping, he tapped me on the shoulder, shook my hand, and thanked me for preventing him from doing something “potentially very stupid”, as he put it. Sometimes it’s all worth it.

Today was a GOOD lunchtime QRP session.
The good news is that I am comfortable enough at the new job, where now I don’t mind heading out to the car to conduct lunchtime QRP sessions. You always kind of wonder at a new place …. what will they say, you know ……. about that guy that sticks the antenna on his car roof and starts doing something with a small radio ….. is he a spy? A drug dealer? Some kind of foreign agent? As it turns out, the parking lot is HUGE and nobody pays me any mind.
The past few days, I was getting skunked. No contacts, and in fact I wasn’t even hearing much of anything. And silly me, the last thing I think is “dead bands” – nope, the first thing I think is “Crud! What did I do to the rig?” “Did I mess up the antenna?” Stuff like that – the first thing I think is that it was me, I screwed something up!
But today ……. today allayed all my concerns. Today, 17 Meters during lunchtime was almost magical. In short order I worked Milan OK1KW in Praha in the Czech Republic. Milan was calling “CQ FISTS” and I answered and we ended up having a very pleasant QSO. Milan was 589 in NJ and I received a 549 in return.
After ending the QSO with Milan, I heard Frank OV1CDX calling “CQ DX”. I figured to myself, “Hey, I just worked the Czech Republic, so why not Denmark?” I put my call out a few times and Frank answered. He was a good strong 599 in NJ and I earned a 559 in return. Cool – the band was hot!
So now the decision comes about ….. “I have 15 minutes left. Do I tear down and head back in, or do I try for one more?” No contest! Try for one more, as the signals were abundant. And I did, and I made it!
This time I worked Serge R6YY. This was the tough one of my session, as I had to send my information to Serge several times. Thanks to his fantastic ears, we were able to complete the QSO. Serge was only 579 here in NJ, and I was only 439 in return. A tough one, but we did it!
