Tonight, we tried to listen in to the planned ARISS contact between Paolo Nespole – IZ0JPA – and the YOTA event taking place at Gilwell Park at 18:38 GMT. Sadly, it didn’t work out as expected and we only got to hear a very brief question from Paolo about the quality of the contact!

Fortunately, the nice at NASA agreed that the contact could be tried again on the next pass at 20:14 GMT. This worked beautifully. Because it was almost dark we could not only hear Paolo in the ISS but also see the ISS as it tracked across the sky!

Further details can be found here. You can listen to the converstaion between Paolo Nespole and YOTA 2017 below.

An excellent evening operating from the beach at Languard View Point with the Felixstowe & District Amateur Radio Society. Managed to work Germany, Hungary (~850 miles) and Italy using my 1-Watter and an Inverted V antenna. The beach there is not very tent peg friendly so my pole was held up using three bags of pebbles where the tent pegs would have been.

Went to the Martlesham Heath 100 Year Celebration Weekend MH100 and helped operate the special event station GB4MH ran by the Felixstowe & District Amateur Radio Society.

Conditions were not brilliant but we got out!

A new toy! I've been on the lookout for a small Morse paddle to use while out /P for a while and this one caught my eye. It's made in America by AMERICAN MORSE EQUIPMENT and comes in kit form. Assembly takes about 10 minutes! It goes nicely with my 1-Watter!

My Christmas present to myself was a 1-Watter QRP transceiver kit from http://www.kitsandparts.com/. It arrived from the USA in a well packaged cardboard box with the serial number for my kit being 749-40. In the box were several plastic zip bags containing a high quality PCB and all the necessary components. The build instructions can be found here.

The finished transceiver is shown below. Note that the kit does not come supplied with a box you must buy that separately.

The picture below shows inside the box though this was taken before the frequency display was added.

The build process was straight forward. I followed the instructions to the letter and my only confusion involved the winding of pig-nose core but a quick email soon resolved that issue. The transceiver worked first time with a successful contact with Z33PB in Macedonia, approximately 1200 miles, he gave me a report of 559.

Operating a radio with no frequency display seemed very strange to me so I decided to add a frequency display. Looking around the internet it seemed obvious that the offering from QRPGuys would be a good start. QRPGuys actuall have a document that talks about added their frequency meter to the 1-Watter!

My local radio club had a rig testing evening, I took the 1-Watter along to find out out just how much power it put out and to see the quality of the transmitted signal. It turned out that the radio actually puts out 1.3 watts and the output harmonics look like:

For Christmas I was given a JYE-TECH capacitance meter kit. These are readily available on eBay and other suppliers for < £9. All the parts were present and the build process was a pleasure. It seems to work rather well too. I’ve used it to check all the capacitor values in a One Watter kit; all capacitor values read as expected. The only slight issue is the requirement for a filter over the seven-segment display.

Tip: when you hit the zero button wait for it to settle as display something other than C0 before connecting any capacitor.
