630m QRP WSPR (Saturday)

My 10mW ERP 630m WSPR (measured) was turned on at about 2020z. So far, just 2E0ILY/KIWI (209km) spotting me.

It is very disappointing to see I am the only UK station sending 630m WSPR according to WSPRnet at present. 


17 different stations have spotted my 10mW ERP 630m WSPR in the last 2 weeks.

Spring is coming - NOT amateur radio

 

Trees are coming into leaf. It felt much warmer today on our walk around the village. It is windier.

8m dipole

As mentioned before, it looks like my 8m dipole antenna system has an intermittent fault. Recently, I decided to concentrate on 8m TX with ISM restrictions, which means 10mW ERP. WSPR gives me the best chance. I doubt 8m FT8 at 10mW ERP would be enough.

A reminder that, certainly in the UK, possibly elsewhere, under ISM rules 8m beaconing is licence free and open to all. A full T&I 8m TX permit costs £50 annually in the UK. With more countries opening the band for real amateur radio research, I keep my fingers crossed that radio amateurs will eventually be granted restricted access with conditions. I have long said that just 5kHz in the ISM band would do.

For 10mW ERP tests the antenna must be reliable.

The actual antenna and coax are not problems, whereas erection is more of an issue as this requires ladder work. I can probably manage OK as the ladder work is quite low, but I get giddy very easily these days so even a short distance off the ground is harder than it once was.

500uW 10m WSPR again

My 10m WSPR beacon, without the PA, is on again. At 0846z, no spots. 

This QRPP is really great fun and definitely worth trying in the upcoming Es season. I suspect FT8 would not work.


UPDATE 1817z:
23 spots of me so far today. Please note that my beacon is pre-programmed to report 0.5W even though the power with the PA off is 30dB lower (500uW).

Return of the migrant birds - NOT amateur radio

When I see the first migrant birds returning from Africa, my heart jumps for joy.  In this troubled world it is good to know that cycles that have gone on for thousands, possibly millions, of years carry on despite us. 

Yesterday I saw my first housemartin, although I have yet to see a swallow. 

In 4-6 weeks we will hear the screaming swifts feeding on the wing. We'll look up and there they will be and my heart will lose another beat.

Tulip - NOT amateur radio

 This is in our garden.


630m QRP WSPR overnight

An average session overnight with no real DX. 11 stations spotted my 10mW ERP WSPR on 630m.

Sunspots - Saturday April 13th

 Solar flux is 152 and the SSN 83. A=6 and K=2.

630m QRP WSPR (Friday)

 My 10mW ERP has been on for a few hours. 4 stations have spotted me so far.

Nest - NOT amateur radio

A blackbird has decided to nest in the arch over our back gate. 

I had not noticed this nest before, so it may be new. I hope it succeeds.
