8m experiments (Friday)

My QRP signal has now been copied in 4 countries (UK, Eire, Portugal and Croatia).  With the Es season upon us now, I should reach Slovenia OK. If I am copied further, that would be an unexpected bonus.

Earlier today (around 0650z) my 40.680MHz FT8 gear was turned on. This was spotted by EI9KP (649km). It is now on RX only (no spots).

My rig is a widebanded FT817ND and the antenna a low wire dipole.

UPDATE 1232z:  S59F (1205km) spotted on 8m FT8 RX. Definitely Es.

UPDATE 1527z: EI9KP has copied me more than once today and at times very strongly Currently QRT (TX cooling!), but will be back on FT8 TX shortly on 40.680 MHz USB dial.

Still no swallows (barn) - NOT amateur radio

Last year I saw just 2 all year.  It is already April 28th and I have seen none at all. In the past I had definitely seen some by the middle of the month. Perhaps it is climate change or fewer nest sites? 

The next milestone will be the swifts arriving. They are usually a common sight and sound by mid-May. Will they be here next month? 

There are some swallows around, but I suspect there must be far fewer this year.

Shack 2015

 

When clearing some old photos yesterday, I cam across this photo of the shack in 2015. 

How time flies!

10m QRP TX (Thursday)

 Yet again, I am on 10m WSPR TX with the W5OLF beacon. So far just local G4KPX (14km) spotting me.

UPDATE 1033z: Just local spots still. I think even Richard has given up!

8m experiment continued (Thursday)

My 8m TX experiments are continuing today with FT8 transmissions on 40.680 MHz USB dial regularly. 

UPDATE 0903z:   Sadly no spots given or received so far. Currently on RX, but expect to be on 8m FT8 TX again at 0930z.

UPDATE 1030z:  Still no spots.

UPDATE 1702z: FT8 exchange with 9A2Y (1567km).

Grand Arcade, Cambridge - NOT amateur radio

 

The Grand Arcade in central Cambridge is a covered, pedestrian only, shopping area. 

It is one of the few places with a Raspberry Pi shop. Well, it is Cambridge!

80m FETer transceiver


It seems like yesterday, but this was designed in 2008. Starting from the 40m design by W2UW (SK) I wanted to see how simple a transceiver could be made for 80m. The result was the 1 FET FETer transceiver. My main issue was netting on RX.
