Getting over Covid-19 - NOT amateur radio

 As mentioned before, both my wife and I have had Covid-19, we believe for the first and only time. My wife got better after a few days. I seem to be getting better with the worst of the symptoms now gone. We have both (as "old" people) had all our injections and assumed we would never get it! 

As mentioned before we had different symptoms. So far, my sense of small and taste are the same. Since my 2013 stroke these have been "different"  in that I no longer want sugar in tea and coffee. Also, I like sweet things more - quite bizarre!

Anyway, assuming I have no relapses, I think I am getting better. If others get it, I hope you have similar experiences or better i.e. mild, and short.

10m QRP WSPR TX (Tuesday)


My 10m 500mW WSPR beacon has been on since breakfast. So far, plenty of spots from the Canary Is, by what looks like F2. Also, other stations, probably F2.

UPDATE 1325z:  19 spots of me so far today.

UPDATE 2044z:
31 stations have spotted me today as the map shows.

8m QRP FT8 (Tuesday)

My 2.5W has been on since after breakfast, but just spots by a local so far. As usual, 2.5W and the low dipole.

As the solar conditions do not look too promising today, the best I can really hope for is some tropo or aircraft scatter. Even this would be a bonus!

UPDATE 1316z:  ZR1ADI (9777km) has again been copied. With the SSN so low I am pleasantly surprised to see the MUF on N-S paths so high. I was not expecting this.

e-Loran

OFCOM is proposing to offer licences to e-Loran around 100 kHz. I have no idea if this will cause interference to LF and MF amateur bands. I remember the QRM caused by Loran at the top of 160m. I think OFCOM is after comments. See the OFCOM website.

160m QRP FT8 overnight

Stations spotting my 2.5W to the
earth-electrode "antenna" in the

t
My FT817ND and the earth-electrode "antenna" were left on overnight on FT8. I am amazed how well it works!  Amazing that this antenna is invisible. Even my XYL does not know it is there! My noise level in SSB bandwidths is about S8 here.

In all, I was spotted by 55 stations as the maps shows. 73 stations were spotted on RX. The furthermost on TX was OH6BG (1716km). 

My theory is this works as a loop in the ground, so that the efficiency should decrease as the skin depth goes down, so I would expect it to be poorer on 160m than 630m. Also, I was using FT8 which is some 10dB poorer than WSPR. Overall, very pleasing. 

This begs the question - what is it like on 80m FT8? If the match is OK, I shall probably try this tonight!

This is experimentation I can still do! At some point I must try my 2200m (136 kHz) beacon on QRSS. I think it can do QRSS. It is over 10 years since I last used QRSS.

Sunspots - Tuesday October 24th 2023

 Solar flux is 122 and the SSN just 25.  A=3 and K=0.

160m FT8 this evening?

As a change from 630m WSPR, I might try the earth-electrode "antenna" in the ground with QRP 160m FT8 as long as I can get a match that is low enough. 

I cannot recall trying this at this QTH. Mind you, it it is more than a month ago I probably cannot remember it!

UPDATE 1450z:   I turned on my 160m QRP FT8 to the earth-electrode using the same 3C90 matching transformer. With the same taps as used on 630m the SWR is pretty low.

UPDATE 1704z: 2 stations have spotted me on QRP TX (2.5W and the earth electrode "antenna" in the ground) with the furthermost ON7KEC (293km.). On 160m RX stations spotted all over Europe with the furthermost nearly 3000km away. It has just got dark here! The antenna works well even on 160m FT8. The map shows the stations spotted on 160m FT8 RX.

UPDATE 1811z:  7 stations have spotted me with the furthermost LA3MHA (1074km).

UPDATE 1900z:   10 stations have spotted me.

UPDATE 2000z:
19 stations have spotted me, as the map shows. Not bad for the "antenna" which nobody can see!

630m QRP WSPR overnight

 


My furthermost spot has increased in distance. Last night was probably my best ever on the band.

Count your blessings - NOT amateur radio

As mentioned yesterday, I have tested positive for Covid-19 despite having all the injections and avoided it until now. My wife also has it, with different symptoms. At the moment I feel rough and hope things get better soon. I have not felt this unwell since my 2013 stroke.

Just imagine this if I lived in Gaza. I have no sympathy with killing innocent people whatever their religion.  I am sure revenge just fuels the flames.  I just wish everyone could live in peace and respect our differences.

At the moment my symptoms of Covid are many and varied. It feels like a very heavy cold and it hurts when I cough. Also, I have noticed I make far more mistakes typing.

Enjoy every moment.

8m QRP FT8 (Monday)

My 2.5W to the low dipole has been on since about 0945z. So far, no spots.

UPDATE 1424z:  So far still no spots on TX or RX.
