This years JOTA kit is “The Morse Phone” inspired by the “Fullerphone” The Fullerphone was devised in 1915 by then Captain (later Major General) Algernon Clement Fuller of the British Royal Corps of Signals to overcome the common use of earth induction to overhear communications in the closely packed trench warfare of World War I. The commonly used trench buzzer signals could be detected at distances up to 300 yards and speech at 100 yards […]
I got my hands on a set of 2nd hand solar-panels. most of them are rotten. But i found one that works. so a “Sun”day afternoon of toying around gave me some ideas on how to move on. altho the glass is shattered it still works fine.
It’s been a while that i posted, just been to busy. Last weekend was a big step in clearing out the shack of “keep-able junk”. Things that are in the way and i don’t want to trow away. In March i “unbuild” a garden shed from an other OM and now it was time to rebuild it in my own garden. The first things that got in where my antenna’s.
I found an old solar pannel in my junkshed. Do i thought i gave it a try. 150mA and all i need is 55mA. So.. testing..
Today was a nice day to build the delta loop. Using the calculator on the website of WS6X. Resulting in 21.6m of wire… after cuting off some 40cm it now works fine across the band.
Building a balun for a delta loop. I had same advice as at first i wanted to build an air coil balun. But i was told to use an ferriet coil. So i did. Just an simple straight true 4:1 balun. There are loads of pages describing how and why it works and how to make them. So i won’t bother anyone with that. Instead i build one and yes it worked… I used 2 […]
This year i participated in the annual PACC contest. More for the fun of it then to actually win. I enterd in section F: Single Operator Mixed QRP and came in 18th from the 22 participants in the category. With only 20 QSO’S in the log i find it nice not to be the last.
During Eastern 2017 we, PA3AUV and me, where active on several bands. We didn’t QSO a lot. Just a quick impression.
Today I finished the qrp backpack. First I made the pieces of wood i needed….. well before i write a boring story. Here are the pictures. 3x 20m 4mm line to put the antenna in the trees. Quick lock hooks also for mounting antennas. It needs some detailing but the basics are here and it works. Even made a qso on 20m on batteries as test. I hope the next pictures will be […]
I wanted a field backpack for ages. Yesterday i figured i could reuse the sem35 pack. So i started drawing to see how it would all fit in. Stil in the drawing stage. But here is a glimps. It will fit a batterij 12v 5 or 7amps. The ft-817nd, LDG Z817 and my wire antennes. Also it will have the PL on the front and a charge socket with a switch to select On (batt […]
