Sometimes you just can’t go by what the propagation numbers tell you. Last fall when we were seeing sunspot counts topping 200 and solar flux counts near 200 I just wasn’t able to contact Australia nor New Zealand though they were blasting into SoCal clear into the early evening hours. So imagine the shock I received Saturday afternoon as I’m sitting in the Kmart parking lot and I hear a VK4 station calling CQ, I answer his call and on the first attempt I get this…

Yes, that is a stock FT-817 I’m using, barely 5-Watts out. Antenna used was an ATX Walkabout mounted on the roof using a MFJ BNC magnetic mount. For power a fold-up 15W solar panel, 10A solar charger and a 9Ah Solid Lead Acid (SLA) battery. The entire system is completely portable and stores neatly in my backpack.

‘Tuna Tin 2’ 35th Anniversary Issue



















From the website

The original cover article for the Tuna Tin 2 was published in the May 1976 issue of QST. Over the years this quintessential QRP transmitter has been built by thousands of amateurs. QRPme kits several versions of the TT2 and offers up one more. This 35th anniversary issue goes back to the basic TT2 design and brings it up to date. For overall clarity, the parts are laid out on the board in the exact same way the schematic is drawn. The toroids and transformer have been replaced to both reduce the complexity and time of the build. ALL the connectors are mounted directly to the board so there is no external wiring to mess around with. The pads, traces and spaces are BIG to help reduce soldering problems for beginners. All the components are supplied with the kit so all you need are tools, soldering iron and solder. Of course, you will need to come up with a can to mount your finished kit on… You could have a tuna fish sandwich for a snack while you build the kit. I prefer a small can of Dole\’s pineapple chunks. Look for a tuna fish or pinapple can with a pull top lid! After you pull the tab, a small lip remains on the outside rim of the can. The TT2 board sits on this rim and is held onto the can by a bolt through the board and bottom of the can. You will have to drill a hole in the bottom of your can to mount the board….

The 35th anniversary Tuna Tin 2 transmitter kit is THE perfect kit for club builds and Build-a-Thons due to its easy construction and HIGH degree of probability of having a working kit at the end of the build….even for 1st time builders.

N6QW’s Shirt Pocket Sized 20m QRP SSB Transceiver

W1JSB SW-80 Project

Johann Busch – W1JSB, got a little creative on a recent project involving the Small Wonders Lab SW-80 QRP Transceiver kit. Using a $9 water tight enclosure and various other parts totaling $179, he came up with one of the cleanest installs I have ever seen. Click the photo above to view his step by step article.

ARGH thats twice now :o(

Last week I attempted to contact W4GKR on 15 meters, he was able to make out all but one letter of my callsign and then the band died. Today during the contest I was back on 15 and made contact with a station in Hawaii. The station called me back and gave my full callsign (KE6ZGP) then gave his callsign which I thought was KH7N, however, a quick email reply from KH7N reveals he was not the station I contacted. So who the hell was it?
