QRP VLF earth-mode


8 years ago I was experimenting at VLF with earth-mode signals through the ground getting 6km with 5W as the photo shows. 

Another cancelled rally

I have just heard about another cancelled rally. Let us hope next year is better! This time next year we should have a vaccine and things should feel more normal. This year has been odd for most. 

The Hornsea Amateur Radio Rally was due to be held Oct 18th in Driffield, but this is now cancelled.

2m AM QSO - 100 miles - 10mW - halfwave whip

My  XYL was looking in our loft for some pictures and came across my mobile logbook that I had not seen for over 7 years. I have never managed to get in our loft since my 2013 stroke. 

In the logbook is my Fredbox QSO across the Channel with 10mW and a halfwave whip on 2m AM in 1976. This was one of my all-time best ever QSOs. See logbook page photo below.

Years later the Fredbox was revived and used for some local QSOs again.

6m FT8 (2.5W and the V2000 vertical omni)

In a few minutes I hope to turn on 6m FT8.  It is now 0647z.  If I spot anyone or anyone spots me, I shall be pleased and amazed. 

However, they do call it the "magic band" as from time to time strange things happen. 

The most probable outcome is white noise, followed by the odd G spot (from dedicated people who like punishment) and possibly the odd European by aircraft or Es.

UPDATE 0723z:  6m FT8 now turned on. No spots given or received.

UPDATE 1025z: Just a spot from G0PQO (50km). No spots on RX and no QSOs.

UPDATE 1806z:  Now QRT. With no spots at all on RX and just 1 spot of me on TX, today has been a poor day.

Interesting kits

Steve G1KQH has brought these interesting kits to my attention.

Sunspots - Thursday October 15th 2020

Solar flux is 75 (higher than for some time) and the SSN 12. A=2 and K=0. There is definitely evidence building that we are on the up-slope of cycle 25.

2m FT8 (2.5W and the big-wheel omni)

At the moment I am again on 2m FT8 QRP. It is now 0907z. 6 stations have spotted me with G4RRA (333km) in Devon the furthermost,and I have spotted 2 stations so far.

UPDATE 1423z: 11 stations have already copied me (no QSOs yet) with the furthermost being EI2FG (565km). Also copied multiple times in Northern Ireland. 17 stations in 5 countries spotted here.

UPDATE 1530z: After a period on RX only, I am back on 2m FT8 TX. 4 stations have spotted me in the last 10 minutes including G4RRA (333km) in Devon again. On RX 22 stations spotted today.

70cm activity contest

As usual, I entered this competition organised by the RSGB last night entering the low power section with 10W and the 2m big-wheel omni antenna. I was on for about 45 minutes making 4 QSOs as shown on the map.

Sunspots - Wednesday October 13th 2020

 Solar flux is 72 and the SSN back to 0. A=3 and K=0.

QRP on YouTube

A recent visit to YouTube suggested there were lots of videos about QRP operating. As you know, a lot of fun can be had with low power.
