8m QRP FT8 (Saturday)

In a few moments I hope to go on 40.680 MHz FT8 QRP TX with my QMX+.

UPDATE 1629z:  Spotted by WW1L (4976km). First transatlantic spot of me on 8m QRP (2W) FT8 this month.

Rally on Sunday

The following is due tomorrow. Usual caveats about travel apply:

Sunday February 9th - Radio Active 25 - The Nantwich Rally, Nantwich, CW5 5DG. See radioactivefair.co.uk.


10m QRP FT8 (Saturday)

My QMX+ was turned on at about 1020z.


UPDATE 1033z: 27 stations have already spotted me. These look like single hop F2.

UPDATE 1220z: 
168 stations have spotted me.

Clearing the decks?

 A major UK dealer is discounting all its stock of second hand FT817ND transceivers. I wondering if they are expecting many to be traded in soon so people can buy the new Yaesu FTX -1F assuming it comes!

Brunch - NOT amateur radio

Every Wednesday my wife has her University of the Third Age lecture in Cambridge so we have brunch beforehand. 

Sunspots - Saturday February 8th

 Solar flux is 182 and the SSN 179. A=4 and K=2.

This thatched cottage is in the next village of Wicken.

Talk without talking

At the end of the month I am giving a talk with a difference at the Cambridge Radio Club. The format is different from normal in that I prepare the slides but someone else does the talking, because I can no longer talk at presentations. This is the second time I have done this.

This time my talk is on 8m.

8m QRP FT8 TX (Friday)

 At 1315z I turned on my QMX+ on 8m FT8 TX. At 1320z, nobody had spotted me.

UPDATE 1610z: QRT on 8m FT8. No spots of me.

10m QRP FT8 with the QMX+


Just before lunch I turned on the QMX+ to FT8. Power out is about 3.5W to an end-fed.

UPDATE 1301z:  So far I have been spotted by 162 stations with the furthermost VK6DW (14466km) in Western Australia.

UPDATE 1630z:  Back on 10m FT8 with the QMX+. 100 stations have spotted me recently.


UPDATE 2100z:
  399 stations have spotted me today. See map. QRT soon.

PC and QMX+ puzzle solved

This morning I solved an issue with my QMX+. 

I could not understand why, despite all the settings being correct, my QMX+ refused to have any output on FT8. What had not noticed was that the USB audio on the PC was muted. Once it was unmuted, all was well.

10m QRP WSPR (Friday)

 My 500mW beacon was turned on at about 0900z. So far just EA8BFK (2880km) spotting me.


UPDATE 1240z:  
In all, 8 stations spotted me this morning, before I went to 10m QRP FT8 with my QMX+

4. Set up GB3PI on my IC-705 and check access.

My wife made this collage of Cambridge buildings yesterday. 

She took the photos on her way back from her course at the University of the Third Age.
