10m Simple Sideband

In the next 12 months, 10m is returning as a great DX band. At any part of the solar cycle it can be good for Es contacts in April- August in the northern hemisphere. There is a smaller Es peak in the depths of winter.

When I was fitter, I had the outlines of a simple single band QRP rig for 10m. My idea was DSB based as this was simpler. This was to be paired with a direct conversion RX.

Then my 2013 stroke happened and all development work stopped. 7 years later there may be better options. My hope is that someone else will take this on and try to create a simple, single board, single band transceiver.

Dual band FM VHF/UHF rig

According to Southgate News, Moonraker is selling a dual band amateur rig aimed at foundation licencees. It retails for £89.99 and comes preprogrammed with amateur frequencies like repeaters and simplex channels and set to 10W by default, although it can do 25W.

Anglesey Abbey in dull November - NOT amateur radio

We went for a walk this morning around the nearby National Trust place at Anglesey Abbey. 

At this time of year it looks quite drab. In the summer the herbaceous flowers and dahlias look good and in the winter there are masses of snowdrops and daffodils.

Yes, there are a few autumnal colours to enjoy, but......

Boeing 737 Max: what utter rubbish!! - NOT amateur radio

18 months after it was removed from service following 2 fatal crashes, the Boeing 737 max has been declared airworthy again. My simple question is why has it taken so long? My brother-in-law was on one. Little did I know at the time that his life was in danger.

This whole affair is utterly disgraceful.  I hope Boeing, and whoever deemed it safe to fly originally, reflect on this.

OFCOM spectrum auction

OFCOM has announced details of the next auction of spectrum at 700MHz and 3.6GHz  See their website for details.

Somehow I suspect £100 won't win, so I think I won't bother .😆

Last ones? - NOT amateur radio

Most blackberries have now shrivelled up. The photo shows one today seen on our walk earlier. 

The one I had was bitter. 

2m FT8 QRP

It is now 1002z.  For about 10 minutes I have been on 2m FT8 QRP using my 2.5W and the big-wheel omni antenna. So far I have been spotted by 11 stations already with the furthermost being G7RAU (461km) in Cornwall.

I am still puzzled by WSJT-X RX with Windows 10 and the SignaLink USB. At times it works whereas at other times the waterfall is smeary and I get no decodes. At first I thought this was just the first few minutes, but I have seen this be OK then not.

UPDATE 1434z:  Spotted by 18 stations in 3 countries and I have spotted 44 stations in 7 countries today with furthermost OZ1CCM (796km). Just turned TX on again as it was turned off.

2m FT8 RX
UPDATE 1757z:  So far today I have been spotted by 23 stations on QRP TX and I have spotted 54 stations on RX.
