Hot Iron archive

Some may like the archive of W4NPN to "Hot Iron",  which many builders will find very useful. Hot Iron is an online magazine for constructors.

Every now and again, you need to work out something "radio" and a calculator can come in very handy. This site has some very useful calculators.

2m FT8 activity contest

Starting at 1900z is the RSGB organised 2m FT8 activity contest. At the moment I am RX only, although I might try TX with 2.5W FT8 with the big-wheel omni later.  So far, 35 stations in 6 countries spotted after 7 minutes!

UPDATE 1940z: 74 stations in 7 countries spotted. 1 QSO just now. RX only again as it is too crowded!

UPDATE 2110z:   96 stations in 9 countries spotted on 2m FT8 RX this evening and 3 QSOs. My signal was spotted by F1FPL (345km). Now QRT. Quite pleased with just 2.5W and the omni antenna.

Summer Saturday - NOT amateur radio


This was Salcombe, where I come from in South Devon, on a summer day many years ago. 

10m FT8 RX

A few moments ago (0955z), I turned on my 10m FT8 RX. As I had just turned the electricity off whilst I changed a bulb in the bathroom, there was no internet, so no spots were appearing on PSKreporter.  Locally, I was spotting several stations.

UPDATE 1024z:  37 stations spotted and on PSKreporter. Most are single hop F2.

UPDATE 1411z:  172 stations spotted.

Stations spotted today
UPDATE 1744z:  476 stations spotted. QRT soon.


E-Field probe RX antenna

This tiny antenna is very effective on VLF, LF and MF. Versions are available which can be bought ready made or as kits.

160m FT8 RX overnight




Overnight I was on 160m FT8 RX. In all, 303 stations were spotted as the map shows.  This was with the untuned 10m antenna.

Dalham near Newmarket - NOT amateur radio

 


This is a village not far from us. As you can see, there are lots of thatched cottages. It is very beautiful.
