Antarctica on 10m

 In the last few days my 500mW 10m WSPR has been spotted 10 times in Antarctica by DP0GVN (13685km) on the German base down there.

10m 5W FT8 (Saturday)

 My gear was turned on  at about 0850z.

UPDATE  1250z: 256 stations spotting me so far today.

Sunspots - Saturday September 27th

Solar  flux is 165 and the SSN 137.  A=7 and K=2.

15m 5W FT8 (Friday)

 Earlier, for a change, I went briefly on 15m FT8. I did not stop on long.

6m 5W FT8 (Friday)

My gear was turned on at about 1300z.

UPDATE  1328z:  So far today, spotted by 7 English stations. Reports suggest I might be copied at 1-2W, although this will depend on the local noise floor. In most urban areas this is getting worse. I think my chances of being spotted "across the pond" this autumn by F2 with my low ERP are very slim! It is very unlikely the MUF will climb this high and with my low ERP it is very unlikely I would be spotted.

"Our" tree

Every year we take a photo of the same tree at nearby Anglesey Abbey

I take a photo around this time when the leaves are changing colour before the leaves fall for a few months over winter.

UV-5R Mini

This was bought recently and I am now familiar with the menu and have successfully programmed some channels using Bluetooth. 

It will probably be used mainly on RX.

How much pull can you get with a VXO?

A VXO can be pulled more by adding an inductor in series with the crystal or putting more crystals in parallel. My own experience was that the more a VXO is pulled the less crystal control is obtained. So it is important not try to pull a crystal too much. DX Explorer has a video showing some experiments with pulling a VXO.

10m 500mW WSPR (Friday)

My beacon was turned on at about 0815z.

UPDATE 1313z:   11 stations have spotted me today. This looks like F2 propagation. The furthest is K6RFT (6958km).

10m 500mW WSPR yesterday

As well as plenty of stations in the USA and Canada I was again spotted in Antarctica. 

I think I have been spotted in Antarctica 7 times this week.
