70cm FT8 contest

This evening there is a contest on 70cm FT8. 12 stations have been spotted with the furthermost PF1B (305km). 

I am using the V2000 vertical omni antenna. Although I had 1 QSO and have been spotted by 3 stations, I am mostly RX only.

UPDATE 1850z: 15 stations spotted with the furthermost EI8KN (518km).

UPDATE 1950z:  20 stations spotted. This is with the vertical antenna!

UPDATE 2053z:  29 stations spotted on RX and 5 stations have spotted me with the furthermost F5RZC (208km). This is by far the most stations I have spotted at one time on 70cms. My power is 2.5W. See map for the stations spotted at 2035z.

UPDATE 2200z: 30 stations spotted.

10m AM

 One of the pleasures of the last solar peak was hearing the USA AM signals just above 29MHz. One of the beauties of 10m is its size. With 1.7MHz of bandwidth all modes can be accommodated without issues including FM and AM.

10m (28MHz) operation

10m (28MHz) is probably my favourite band. Antennas are modest and some remarkable DX can be worked with low power. I am sure beams might help when conditions are marginal, but I obtained 10m QRP SSB DXCC about 30 years ago with simple wire antennas. I have even heard USA AM stations with a super-regen and a base loaded whip in the car.

70cms (432MHz) band

In the past I have had a lot of fun on this band, which is shared with other services. It seems to experience more localised tropo openings than 2m. Antennas are small. They look like UHF TV antennas.

A reminder that there is a 70cm FT8 contest this evening from 1700z to 2100z on 432.174MHz. Many PAs use vertical polarisation, so I shall be using my V2000 vertical.

10m FT8 RX

In a few moments, I intend to go on 10m FT8 RX. It is now 1006z.

UPDATE 1105: So far today, 139 stations already spotted with the furthermost VK6DW (14466km). The band seems busy. See photo.

UPDATE 1208z:  197 stations spotted.

UPDATE 1357z:  284 stations spotted in the last day on 10m FT8 RX.  10m is a good DX band again! I must soon listen just above 29MHz for USA AM stations.

80m FT8 RX

In all, 932 stations spotted last evening and overnight on 80m FT8 RX on what must be one of the most stupid antenna and ground systems on the planet, proving that for FT8 RX almost anything can be used. In my case this was the coax to my 2m big-wheel, and a mains plug ground, resonated via a ferrite rod ATU on the bench. 

Blink - NOT amateur radio

Our grandson is 14 years old today and it seems like only yesterday that he was born. Moral? Enjoy every moment.  Just think the same again and he will be 28!

Sunspots - Wednesday November 10th 2021

 Solar flux is 92 and the SSN 40.  A=6 and K=3.

80m FT8 RX

Since about 1915z I have been on 80m FT8 RX using the coax to the 2m big-wheel tuned via the ferrite rod ATU. So far, this evening 71 stations spotted.

UPDATE 2225z:   453 stations spotted on RX.  The band seems very busy as the photo shows.

Autumn is coming - NOT amateur radio

Autumn is late this year with many trees still with leaves. It is also very mild. 

We were picking up some leaves in the garden without wearing a coat. It felt more like late summer than November.
