Plans for Tuesday

At first, I shall try 10m FT8 using the QDX transceiver. If successful, I may try 8m FT8 later. I am toying with trying 8m WSPR at 1W around 40.680 MHz. 

Pye Telecom/Philips - NOT amateur radio

Most of my working life was in design in the Pye Telecom days. Although Philips bought Pye in the late 1960s, it was very "hands off" for years. Eventually we badged some products Philips such as this PF85 shown here. It was a good product with some truly great engineers. After the late 1980s I think most products were badged Philips. The PF85 and the PFX shared many modules.

Sunspots - Tuesday February 28th 2023

Solar flux is 161 and the SSN 192. A=94 and K=4. 

Tree stump - NOT amateur radio

Yesterday, we went for a delightful walk at the nearby village of Dalham in West Suffolk. On the way we passed through an avenue of trees up the hill to the church. We passed this old tree stump.  I bet this old tree had seen some history.

FT8 in the quiet solar years

At the moment, 10m FT8 seems to be able to deliver worldwide DX daily. In about 5 years' time we will be at the depths of the solar cycle and 10m may appear dead again. This is when WSPR and FT8 could prove extremely useful.

Both the WSPR and FT8 "watering holes" are quite small, but well monitored. I hope many will stick with these modes on 10m as there is a great deal for us to learn. Especially on N-S paths it would not surprise me at all to find paths open, even with very low solar activity.

Often low 10m activity is not because of conditions, but people going ever lower in frequency for an easier life. Just listen to CB nearby.

New 8m T&I licence obtained

Even though I wish the RSGB and OFCOM would see sense and grant real experimenters an NoV for 8m, I have shelled out (yet again) to continue research at 8m until April 2nd 2024.  In my view their position on this seems totally stupid in the extreme!!!   As before, I asked for digital only at QRP.

I really hope as many as possible come on the ISM band without a licence whilst ensuring they are fully compliant with any national requirements. As I said yesterday, it is my view that anyone in the UK can run 10mW ERP WSPR beacons in the 40.66-40.70 ISM band without a licence and with whatever callsign you like!!

Strictly  speaking, you do not need to give your location, even with the T&I licence either! Personally I think this is bizarre.

Callsigns are not a requirement of ISM use, although I think there is nothing whatsoever to stop you using your amateur radio callsign as an identifier. This is not the Amateur Radio Service. You could, of course, make up your own callsign like "your initials"123!  If using WSPR, it is advisable to make sure the format of the callsign will be reported to WSPRnet.

10m QRP FT8 with the QDX

This morning started with a slight panic. I went on 10m FT8 with the QDX and thought the SWR looked high. It was as if the QDX was still on 20m. Then it clicked - I was on PWR not SWR. All was well and the SWR very low!!

My gear was switched on at about 0850z. It is now 0900z and, so far, 25 stations spotted on RX and 4 stations have spotted my QRP FT8 TX.

UPDATE 0921z:  11 spots of my QRP from Eastern Europe. I assume this is F2 propagation.

UPDATE 1036z:   20 stations have spotted me with the furthermost 7Z1IS (4948km). On RX, 99 stations have been spotted here.

UPDATE 1400z:  31 stations have spotted me on 10m FT8 and I have spotted 301 stations.

UPDATE 1424z:  45 stations have spotted me with the furthermost ZS3SH (9149km). On RX, 372 stations spotted on 10m FT8. Still using the tiny QDX.

UPDATE 1542z: Today I have been spotted by 87 stations and I have spotted 487 stations. In just a day, I have been spotted on 5 continents with the QRP QDX on 10m FT8 as well as had many QSOs on 10m FT8.

UPDATE 1918z: 119 stations have spotted my QRP 10m FT8 today and I have spotted 565 stations. Not a single station has been spotted from North America.

UPDATE 2025z:  120 stations have spotted my QRP 10m FT8 today (see map) using the QDX.

Early tests on 481 THz

 

This was 2012. It was an eye opener for me. 

Sunspots - Monday February 27th 2023
