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
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.

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.

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.
