17m FT8 QRP (Sunday)

 At about 0835z I went on 17m FT8 with 2.5W and the tiny indoor loop. It is now 0932z. So far, 2 stations have spotted my QRP TX with the furthermost being UR7IM (2631km) and on RX 28 stations spotted here with the furthermost HL5BLI (9059km) in South Korea.

I remain amazed how well this simple QRP set-up works. Later, if I have the energy, I may try thicker wire for the loop. Somewhere in the garage is the roll of central heating pipe that I might use. Failing that, just thicker copper wire or a parallel stretch of copper wire might make things even better.

UPDATE 1208z: 89 stations spotted so far on RX.

UPDATE 1430z: 138 spots of me in 5 continents today on 17m FT8 RX.  4 spots of my QRP on TX.

Shack

This photo may have been on before. If so, my apologies.

It shows me in the shack checking the birds in the garden with binoculars. Building is done on the left and operating on the right.

The photo makes the room look much bigger than it is. 

Did we really have holidays? - NOT amateur radio

This photo shows a crab lunch (excellent) we had last September when we were in North Norfolk. 

Things felt almost normal.

They are coming - NOT amateur radio

Looking at the latest Devon bird sightings, I see that sand martins have started to arrive. These birds are among the first migrants to come.  Swallows usually arrive here in East Anglia in early April with swifts early May. The photo shows a sand martin.

Flower pot antenna

Steve G1KQH recently sent me an email with some useful links on how to make 1/2 wave verticals. I am sharing it with you in case this gives you ideas.

"The latest G4NSJ video pointed me to investigate..

Cheap to make for anything from 28MHz to UHF I guess.. Ideally a starting point is to make one for 2m

Gain 1dB over 1/4 Wave

Details here: 


You can even make it Dual band:

There is even an online calculator:

17m FT8 QRP (Saturday)

At about 1130z, I went on 17m FT8 with 2.5W and the tiny indoor loop. It is now 1141z and 3 stations spotted on RX with the furthermost EA8WU (2985km) and nobody has spotted my QRP on TX. 

UPDATE 1145z: So far, 4 stations spotted on 17m FT8 RX.

UPDATE 1259z: 15 stations spotted so far on RX. Nobody has spotted me on TX.

UPDATE 1400z:  2 stations have spotted me on TX and 37 stations spotted on RX.

UPDATE 1555z: 4 stations have spotted my QRP TX and 65 stations spotted on RX with the furthermost YB1AR (11781km).

UPDATE 1820z: 72 stations spotted today on 17m FT8 RX today. QRT soon.

630m WSPR TX 4 years ago

 


The table shows the stations spotting my 10mW ERP from the earth-electrode "antenna" in the ground in 2017. At the moment my transverter is faulty on TX, so I am restricted to RX. 

The tiny indoor loop

This is the inside of my loop antenna used successfully on 20m FT8 to 10m FT8. I am amazed how well it works. 

The wire used for the loop is quite small and I might try much thicker wire. Tuning should be sharper, but efficiency should be higher. My concern is higher Q means higher voltage at the high impedance point.
