6m QRP rigs

In many ways, 6m (50MHz) is an ideal band for experiments. Short RF leads are always good, but 6m is a forgiving band and you can get away with HF constructional techniques. It is 2MHz wide here in the UK and this means all speech modes can be fitted and used. The page below shows a number of links to 50MHz projects.

The storm that wasn’t

By now, most of you have heard that, at least in the New Jersey area, "The Blizzard of 2015" has turned out to be a big bust. The forecasters were warning us of 18-24 inches (45-60 cm), plus. Instead what we actually received was about 4 inches (10 cm).

I am one of the ones who is not disappointed. I would much rather have the weatherman tell me I am going to get 24 inches of snow, and only get 4, as opposed to the other way around. Meteorology is an art, even to this day. To anyone who is forcing the weather people to eat crow today, I say, "Let's see YOU try it for a while!". I am hearing so many people say, "Oh yeah, I knew from the beginning it wasn't going to be that bad."  Yeah ..... right.

Listening to New England stations coming through Echolink on the local repeater, I understand they are getting hammered, as predicted. Stay safe, warm and dry, my friends.

Even though we didn't get the snow, we did get the cold and the winds. Not gale force winds, but when I was out there shoveling snow, I was chilled to the bone. And the whole time I was removing snow, I was dreaming of something like this:



Thanks to Sean KX9X for posting this.  Some portable outdoor QRP in a nice, warm sunny location is EXACTLY what the doctor ordered, right about now.

On a side note, the office was declared closed for the day last night, when the ominous forecast was still hovering over us. So when the snow stopped this afternoon, having some time available, I went out and switched the coax from the EDZ over to the W3EDP. Much to my relief, the W3EDP hears fine again! It loads up easily on every band and the KX3's auto tuner handles it with nary a whimper.

As it turns out, the coax problem on the W3EDP was entirely may fault. When I went to disconnect the coax from the balun at the end of the W3EDP, I noticed to my horror, that I had never sealed the connection. It's no wonder that water got in there. This time, I double coated the connection with tape, added some plumber's putty over that, and added a final layer of tape.  If the W3EDP plays as well as I think it will, I may just end up taking down the EDZ this Spring and keeping the W3EDP as my primary wire antenna.

0.2 Watts to South Africa

This is a new one for me: Norway-South Africa on 30 m WSPR in the middle of the night. Again I am amazed at what this mode can accomplish, and also what my little Ultimate 3 kit is able to do. 
The antenna used on my side was my trusty old 80 m long horizontal loop fed with a 4:1 balun and no tuning beyond that (SWR 7:1). Output power was from a single stage BS170 driven at 5 Volts, or about 200 mW in a 50 ohms load. In this particular antenna, the output is most likely much lower. 
ZS6KN is the only non-European station who has heard me this night on 30 m, with a marginal SNR of -27 dB.

It’s time for a change

Good evening all, as you can tell from the lack of updates on my blog my time has been spent elsewhere. The blog is still a very important to me and reading the others blogs is very enjoyable, I am committed to my blog but not as much for the last few months. This is not radio related at all and is by no means an advertisement. Julie and have decided to work on our overall health and we are under going a lifestyle change. We have decided to eat more of a plant based diet and move away from the processed food (or yummy food) We both have been very preoccupied with reading and research to make sure what we end up with  the best fit for our lifestyle. We have decided to start our journey by juicing to plain old cleaning out our systems. Then its largely a plant based diet with some juicing on the side. So this has kept me very busy and away from positing in my blog. We both hope to loose some pounds and overall eat and get healthy. So the blog is not gone by the way side I'm just getting my health back on track.

Poppet 160m AM transceiver

This little top band AM transmitter and a companion receiver were first published in the GQRP club SPRAT magazine. This TX version was built by M0DAD. Where the noise floor allows, 160m AM is quite popular for local nets.  There is something nice about “rolling your own” builds and getting satisfying results without spending a fortune. For daytime local use 160m AM is a great mode and rigs are simple. I am still surprised that more is not made of AM on 10m at night for local nets here in the UK.

CLE190 Logs

YJ-200KHz - Victoria Int'l
Listeners towards the central and southern portions of North America reported phenomenally good conditions this weekend, most unusual for a CLE event! Out west and here in BC, conditions were not noticeably enhanced and could best be described as kind of 'mushy' ... most signals were a struggle. The further south you went, the better the propagation became.




CFL Crud
Unfortunately, I am still struggling with noise pollution (cheap or failing CFLs) in a house about ten properties away, creating a constant 60 Hz hum and drifting birdies throughout the band ... as it was during the last CLE. Hopefully the owners of the home will return before the next CLE arrives!

Listening for NDBs is a practical way to check out your LF receive capability, should you be interested in developing a good 630m station or in following the nuances of night-to-night MF propagation.
