Amateur radio below 9kHz

 


This was 2011. It is a long time since I did experiments at sub-9kHz

4m Homebrew transverter

 


I came across this photo yesterday. 

"Our" windmill - NOT amateur radio



This photo was taken in 2016 and shows our windmill next door.  The windmill is part of the very impressive Burwell Museum that opens next weekend after the winter.  It is open Thursdays, Sundays and Bank Holidays Easter until late October. The views from the fully restored 200 year old windmill are impressive.

15m Pipit transceiver



This photo of my homebrew 15m QRP CW transceiver was found when I was looking through some old stuff. This was an 800mW transceiver. It worked very well and was the only rig used for several months.

4m EI4RF beacon - 70.013 MHz

Currently I am on 70.013 MHz FT8 RX, hoping to see the EI4RF beacon, that I believe has some FT8 sequences.  I am not hopeful. They say tune to 70.012 for FT8.

See https://www.qrz.com/db/EI4RF

UPDATE 2050z:  Nothing seen. I shall try for another 20 minutes or so and then call it a night.

UPDATE 2116z:   Still nothing. QRT.

6m MSK144

At the moment I am trying MSK144 on 50.280 MHz in a test with OZ9FZ.

UPDATE 2122z:   Nothing so QSYed to 4m FT8 RX.

Bicone antennas

Sometimes people want a wideband antenna covering several bands. One to consider is the bicone. these can be quite large, but can cover several bands.

See https://en.wikipedia.org/wiki/Biconical_antenna .

Solar maximum?

The site I always look at for the latest data is still showing the peak of this solar cycle in November 2023, i.e. this year. The information was only updated today.

See https://www.solen.info/solar/ .

Sign of the times - NOT amateur radio


We have had more cold weather this winter than for a long time. We have also had lots of potholes in the roads! I suspect that councils are trying to save money, perhaps by using inferior materials. As they are finding out, this is quite short sighted as potholes are reappearing in the same places!

4m FT8

Perhaps I am a sucker for punishment! Once again, I am on 4m FT8 on 70.154 MHz. No spots. Last weekend I was spotted by a few stations and had a contact on 4m FT8 with a station in Wales.

UPDATE 1627z: Still no 4m FT8 spots! I find it hard to believe that days have passed and nobody, absolutely nobody, spotted. Looking on PSKreporter, there look to be very few monitors as well.

UPDATE 1757z:  Just G3SHK (200km) spotted, but he could not copy me sadly.

Rain - NOT amateur radio

 Usually this is a dry part of the UK with very little rain. February was exceptionally dry, but March was exceptionally wet. I think we had more rain in March than the whole winter! We needed the rain, but March was very dull.

Sunspots - Saturday April 1st 2023

Solar flux is 129 and the SSN 61. A=21 and K=2.

630m WSPR RX (Friday)

 At 1920z, my 630m WSPR RX was turned on.

23cm SSB sked with G4BAO

This was very successful. John gave me an RS58 report which was very satisfying for 2W indoors to a 2 el yagi indoors. John suggested an FT8 test at some point in the future, which I shall do. Aiming the small beam in all sorts of directions made little difference on John's signal.

Home deliveries - NOT amateur radio


Since the pandemic, many people have turned to home deliveries. We have used these services for many years. You cannot beat looking at goods in shops, but for some things the convenience of home deliveries is great. The downside is shops find it hard to compete and close. It is a very difficult decision. 

Peoples' shopping habits are changing. In my view, the shops that will still be here are those that adjust to this new model, perhaps acting as showcases for goods ordered online. 

Activity levels

Today was an interesting experiment. I tried 6m and 4m FT8. The difference could not be more stark. On 6m I got plenty of spots, whereas on 4m none at all. Many modern transceivers in Europe include 4m, yet activity on this great band seems very poor. 

I guess people are more interested in working new DX than chatting, not that you can chat on FT8!  There is no doubt amateur radio is changing. In many ways this is for the worse. 

Putting a RX on 6m FT8 is more likely to have something "new" than 4m FT8 outside of the Es season. Even so, I am surprised how bad 4m seems to be. I was expecting some activity!

Unless things change, amateur radio will be gone before 2040. At the very least, it will be radically different.

UPDATE 1336z: What will the future of amateur radio look like? The short answer is I do not know! I can see national agencies like the FCC and OFCOM tiring of amateur radio. Instead I can see the allocation of callsigns being delegated to the ARRL and the RSGB. I can see this spreading across the world. I can see a time when the amateur bands that remain become a free for all, without licences, as long as no interference is caused. I can see a merging of licence free bands and amateur radio.

Wicken Fen lunch yesterday - NOT amateur radio

 


This was our lunch at the cafe at Wicken Fen on our walk yesterday.

4m FT8 (Friday)

 At 1140z, I turned on my 4m FT8 with my compromise antenna of the 2m big-wheel and coax tuned via the auto ATU in the FT-710 So far, no spots of me.

UPDATE 1235z:  I decided to go back to 6m FT8 as I was getting no spots on 4m. Clearly few come on 4m outside the Es season.

6m FT8 (Friday)

At the moment I am on 6m FT8 with the FT-710. Several UK spots of me on TX, but no RX spots.

UPDATE 1056z: F4EGZ (668km) has spotted me.

UPDATE  1242z:  Back on 6m FT8. 16 stations have spotted me.

UPDATE 1300z: Spotted by 17 stations on 6m FT8 so far today.

Stations spotting me
today on 6m FT8 TX
UPDATE 1856z:
56 stations in 10 countries have spotted me today on 6m FT8. It is not even the Es season yet! Very few spots (4) on 6m FT8 RX.
