630m WSPR RX


Overnight I left my IC705 on 474.2kHz WSPR RX again using just the outer of the coax to my 2m big-wheel antenna and mains earth. In all, 11 stations spotted.

630m WSPR RX (Sunday evening)


It is ages since I tried 630m WSPR RX. I connected my coax up to my 2m big-wheel via a ferrite rod ATU as the antenna and a mains plug ground. All this is very far from ideal! Judging by results, it certainly works.

630m (474.2kHz) WSPR RX

For a total change, I am on 474.2kHz WSPR RX using the coax up to my 2m big-wheel antenna tuned via a ferrite rod ATU and a mains plug earth.

UPDATE 1826z:  DC0DX (467km) spotted. This rubbish set-up works!

UPDATE 1916z:  Back on 472kHz WSPR RX. DC0DX copied 5dB stronger.

 Looking back I came across this photo from 2014 showing my loading coil for use at 472kHz.

630m (472 kHz) QRP WSPR


For a few years I have not been on 472 kHz. This video was made some years ago and shows the results using just my earth-electrode "antenna" in the garden.

630m WSPR RX last evening


5 stations were spotted with the furthermost LA3EQ (769km) in Norway. No further stations were spotted overnight.

630m WSPR RX overnight?

Once again I may try 630m WSPR RX overnight. It will be interesting to see if any new stations are spotted.

UPDATE 1808z:  My 630m WSPR RX was turned on.  G1GKN (54km) spotted.

630m WSPR RX overnight


My 630m "ad hoc" antenna (coax to my 2m big-wheel via ferrite rod ATU) was left on overnight. In all, 5 stations were spotted with the furthermost OH1LSQ (1733km) who was spotted 12 times! It may be "ad hoc", but it very definitely works.

This was originally shown as FT8 spots. Keith (thank you!) pointed out my mistake that I have now corrected!

630m WSPR RX overnight



Using the coax up to my 2m big-wheel antenna via an ATU I was on 630m WSPR RX. 5 stations were spotted with the furthest SM2DJK (1720km) in the north of Sweden. It was good to see 630m WSPR well used.

630m WSPR receive (Monday)

As my earth-electrode "antenna" is not connected and  my Tigertronics SignaLink USB interface is faulty, I am RX only using the IC-705 and the coax up to my 2m big-wheel via a ferrite rod ATU. 

So far this evening, 2 stations spotted on WSPR with the furthermost DC0DX (467km).


UPDATE 2230z: 
Just 2 stations spotted this evening. I shall leave the RX on overnight.

630m WSPR RX

For the first time this season I am on 630m (472kHz) WSPR RX using my coax outer to my 2m big-wheel antenna via a ferrite rod ATU. I intend to remain on until breakfast.

At the moment I cannot TX on the band because of a fault with my Tigertronics USB interface or lead.

If you can TX WSPR on 630m I would appreciate a signal to test all is working.

UPDATE 1805z:  No spots.

472kHz transverter

The photo shows me testing my 472kHz (630m) transverter in the back of the garage at the old QTH. Later it featured in a QST article. It is still used now producing about 10W into a 50 ohm load and about 10mW ERP with my earth-electrode “antenna “ in the ground.

630m QRP WSPR tonight?

It is very unusual for me to try 630m QRP WSPR at this time of year. Assuming things work, I might well give it a try this evening. 

The noise floor will be higher at this time of the year on MF and that might mask my QRPP signal. It's an experiment, so the worst is nobody spots me! 

I wonder if people have moved to different modes on 630m and I should try a different mode?

UPDATE 2030z:  Initial tests were not successful. It is probably something dead simple, so I shall try and find out what is wrong tomorrow.

630m QRP WSPR overnight

Just 2 stations spotted my 10mW ERP  overnight. These were 2 old faithfuls. I may try occasionally, but suspect my signal is buried in noise much of the summer.

630m QRP WSPR (Wednesday)

 My 10mW ERP WSPR has been on since about 1915z.  No spots of me yet.

630m QRP WSPR overnight

Considering we are in mid June I was quite surprised to see my 10mW ERP 630m WSPR was spotted by 5 stations with the furthermost GM3YXM (425km).

10 Jun 2024

630m QRP WSPR overnight


6 stations spotted my 10mW ERP 630m WSPR overnight. No great DX, but more spots than I was expecting.

MF WSPR tonight?

Although my last attempt with 10mW ERP on 630m WSPR was not too great, I am tempted to try again this evening and overnight. Last night I stuck with 6m FT8.

7 Jun 2024

630m QRP WSPR overnight

Just 3 stations spotted me overnight.  I shall carry on a little longer, although I suspect the season is drawing to a close, especially with my 10mW ERP.

5 stations spotted my 10mW ERP on 630m WSPR overnight. No great DX, although it is June.
