10m WSPR QRP TX and RX

 At present, I am on QRP 10m WSPR using the FT-710. After the first transmission 4 spots.

UPDATE 1625z:  My own 5W WSPR TX has been spotted by 19 unique stations and I have spotted 135 unique stations. Furthermost so far is a spot by WP3SM (6851km) in Puerto Rico.

Tuesday plans

My current plan is to go on 10m WSPR with the FT-710 to see if I can preset the optimum settings for WSPR. I may try 630m WSPR RX after dark. 

Red-legged partridges - NOT amateur radio


We used see these handsome birds regularly in our garden but I have not seen any recently. 

630m WSPR RX yesterday


For the first time I tried my FT-710 on 630m WSPR RX using the coax to my 2m big-wheel via a ferrite rod ATU. Everything seems to work fine with stations in the Netherlands Germany and Norway spotted before I had to turn the rig off.

Plans for the day (Monday)

As we are out some of today, I shall probably go on 472 kHz WSPR RX this evening. It is getting later in the season, so I have no idea how it will go. I shall probably have to use the coax to my 2m big-wheel antenna with some loading.

Muntjac deer - NOT amateur radio

For the 5th time recently in our garden, a Muntjac deer scampered away. These are dog sized deer that look nice, but nibble away at some plants. In recent years, these introduced deer have become far more common here.

2m FT8 QRP


In my view  2m FT8 has been transformational with DX possible at any time with QRP.  Yes, SSB activity has declined, but I feel sure some sort of scatter is being tapped into. 

This is not aircraft scatter as planes are not needed. Personally I think this is troposcatter made possible by the far better sensitivity of FT8. 

The photo shows the received stations on typical day with flat conditions. This was 2019 with just an omni antenna! 

Hallsands Devon - NOT amateur radio


This painting was done in 1884. It shows the coastal village of Hallsands that was washed away early in the 20th century. Dredging offshore for Plymouth Dockyard was blamed. Previously this had been a thriving village famous for crab fishing.
