Summer bedding plants - NOT amateur radio


This morning we went to the local Garden Centre to buy some summer bedding plants. We will plant these tomorrow.

Simple FM bug

Not sure where this is legal , but I don’t expect the power to be very great. I guess you change frequency by adjusting turns on the coil. Might be a fun weekend project.

10m 500mW WSPR (Tuesday)

My W5OLF beacon was turned on about 0630z.

UPDATE  1334z:  So far spotted by just 2 stations in the Canary Is..

6m QRP FT8 (Tuesday)

My 6W was turned on at about 0630z.

UPDATE 1330z: 26 stations have spotted me.

UPDATE 1840z: 91 stations have spotted my 6W 6m FT8. Most I assume are Es. See map.

Tuesday plans

 Probably 10m WSPR and 6m FT8 all QRP.

VLF earth-mode experiments


Back in 2013 I tried an experiment to see where my VLF earth-mode signal could be received in the car. 

My TX was 5W into my grounded electrodes. On RX, I dragged a resonant loop behind the car receiving on a PC.  The earth-mode signal popped up at odd points many kilometres away.. 

Since my September 2013 stroke I have been unable to do field work.

Sunspots - Tuesday May 20th

 Solar flux is 117 and the SSN 66.  A=10 and K=2.

Chromebooks - NOT amateur radio

This afternoon my wife found my Asus Chromebook, that had not been used for about a year. It was like finding an old friend. 

It is blisteringly fast and works really well. I have also downloaded BitDefender (free antivirus) although Chrome is pretty safe and my internet provider also has free antivirus and malware protection.
