Summer migrant birds - NOT amateur radio

Well, just one house martin seen here so far. No swallows, no sand martins. I have heard lots of chiffchaffs. Several reports of cuckoos locally, but not seen or heard one. So far, a disappointing spring on the bird front. Swifts usually arrive here in early May, although I suspect these will be later arriving, in any number, this year. Screaming swifts are a major part of a UK summer. In June, swifts are one of the most common birds seen here.

SAQ (17.2kHz VLF CW) on air May 1st 2018

Apparently, the historic alternator CW VLF station SAQ Grimeton, Sweden, is being fired up on May 1st. This is the first time since 2016. I have a QSL card from them, which came many years ago.

Ephemeral Spring - NOT amateur radio

Spring is ephemeral. At the moment, we have fresh green leaves and blossom. Sadly, in a few weeks this will all be gone.

10m FT8 RX

Yet again I am monitoring 10m FT8 RX. Yesterday was good with lots of real DX and already today Germany and Holland have been spotted.

UPDATE 1125z: Currently 6 unique stations in 4 countries, all in Europe, on 10m FT8 RX so far today. Best DX spotted today is OE3KLU (1233km).

UPDATE 1625z: Now 11 stations in 4 countries spotted on 10m FT8.

UPDATE 2020z: Unbelievable! No less than 11 South Americans spotted on 10m FT8 RX this evening. In addition, a couple of stations in the Canary Is. Is this TEP or F2 layer or Es layer linking with TEP further south?

Sunspots - Saturday April 21st 2018

Solar flux is 73 and the sunspot number 14. A=47 and K=3.

A bit out of touch?

Only today I found out that the GB3PY UHF repeater is moving (or has moved?) to new frequencies to avoid interference. This was announced last December, and only now have I found out! It must be ages since I last had a QSO via a repeater as you can tell.

Optical kit

One of my Facebook memories today is of testing my 481THz optical kit in the garden of the old QTH. In those days I was fit and well. These days, field work has proved impossible although I still hope to restart one day. The photo is here as a reminder (to me!).  And, no, I was not looking at that attractive girl up the street!

All the optical kit was homemade and easy to assemble and test in the back of the garage with very basic test gear. Even the software used was free. Over the horizon testing with optical kit was challenging and great fun. Results amazed me.
