10m (28MHz) is probably my favourite band. Antennas are modest and some remarkable DX can be worked with low power. I am sure beams might he...

Since 0920z, I have been on 10m FT8 RX with the indoor loop. On TX I was getting some RF feedback, so I am RX only at the moment.  Much to m...

Some years ago I designed and made the Tenner transceiver for 10m CW. It produced about 500mW but gave me loads of contacts with just a low ...

At the moment I am on the poorer indoor loop, which is the one used on 20m, 17m and 15m. It sits on the shack windowsill. I reckon it is ab...

As I have my outdoor 10m antenna erected again, I thought I would connect my W5OLF WSPR beacon. This puts out 500mW and transmits 100% of t...

My trouble is I cannot remember where I've posted things! So, if this has appeared here recently please accept my apologies. It is a...

Although I have been on 10m FT8 RX for a while, no spots as yet. Mind you, it is quite early. UPDATE 1100z: Still no spots. An RA2 was spo...

This morning, I am on 10m WSPR (20% TX 2W, 80% RX). Although no-one has yet spotted me, it looks like there is some Es with a couple of spot...

For one night my shack was being used as a nursery bedroom, so I was unable to use it for radio work. As my son, his wife and their 2 little...

Late this afternoon, I decided to try 472kHz WSPR (using the FT817, transverter and earth-electrode antenna (5mW ERP) and 28MHz WSPR (using ...

See https://sites.google.com/site/g3xbmqrp3/hf/10m_op . The above link (on my main website) is my "take" on 10m operation. Altho...

Early morning 10m unique WSPR spots today A modest start this morning with a few Asians coming through. Sunspot count is 259 (high) but ...

Transatlantic spots were being exchanged here with the USA at 2W as late as 2252z last night and with Israel at 0610z (very early) this morn...

Before my program stopped running, 10m WSPR was in good shape up to (at least) 2200z last night. TI3/AB4AW (Costa Rica, Central America) was...

Time now is 1030z and so far only DK3SML (733km) at 0854z has been spotted on 10m WSPR.  Sunspot count is 105 with "normal" HF con...

Today was an odd day on 10m WSPR - some good propagation N-S but very marginal indeed transatlantic.  The band did open up but hardly any tr...

EA8/LA3JJ has already spotted my 2W WSPR 3 times and it is only just after 0800z. Sunspot count is 95 and the forecast is for "stable/...

Atlantic 10m is still (mainly) open to the USA and Canada from just before lunchtime, local time. The sunspot number continues to declin...

Running 2W RF,  VE3GEN is a huge WSPR signal today at +4dB S/N, implying he would be copyable with low milliwatts. LZ1OI is 10dB stronger s...

This afternoon I have returned to 10m WSPR. There are lots of transatlantic reports of my signal, as well as reports of my 2W signal from Ru...
