Flea Market in Frederikssund and Test equipment.

 This was the first larger arrangement I have attended since the corona closed down everything social, sort of.

I am still glad that this was an outdoor event.

It was good to meet some old and new friends. I had been talking to a local on the QO100 satellite, and finally we got to meet in person.

I did not bring too much back home, as the house is quite full of stuff. What I did get, was some good quality attenuators (10W/10GHz/10dB) and an older frequency counter capable of 1300MHz.

The counter has been under test a while, testing the reading of my 10MHz GPSDO. After close to 2 days (warming up the reference oscillator) it looks like the reference frequency oscillator is 2Hz off on 10MHz. Not too bad for HF/VHF, but insufficient for UHF and microwaves. The variation with temperature (there is a simple OCXO inside) seems to be less than 1Hz after warm-up, so stability is quite good.

Reference frequency alignment is in my future. 

The counter does have a 1MHz reference frequency input, so it will also be possible to lock the reference to a GPSDO for the best possible stability and accuracy.

HAM Radio and the Corona Virus.

The western world is closing down, for a while.
The Corona virus crisis has hit us all.
As someone in the rather vulnerable group I have, essentially been in isolation for a week now. Not quite, because this week I had appointments at the hospital for a blood test and subsequent CT-scan, as part of the follow-up on a cancer I had treated - successfully - in 2018.

Since I was out, I did go to the pharmacy, too, just to get supplies of medicine I have been using regularly, especially a means to reduce the effects of pollen allergies.

This crisis may take longer than we might expect, for me, at least, I will hesitate to venture much out into the world (or even in my own country), until we have seen and tested a successful treatment or a vaccine is available.

What does that mean to me? I am fortunate enough to have retired, so there is no **need** to go out much. I can get food supplies and other necessities delivered to my door. Even then, I should be careful not to be infected from the delivery people. The most essential company has already initialized measures in that respect.

Here is the thing for me. I am generally used to living on my own, and have not gone out among people a lot. Yes, sometimes I have gone for a larger event, but that is all on hold now.

This is why I like having HAM radio as my interest, among others I can pursue alone. But with HAM radio, I am still in contact with other people on a daily basis, probably even more so because we are all at home most of the time.

So if I can avoid getting infected I will get through that crisis. Others may not be so fortunate.

To everyone in doubt: If you are an essential part of health care and other necessary functions, take all possible precautions to stay healthy. Many others should be working from home, if at all possible, and so help reducing the spread of the virus. Those of us who are vulnerable due to age or previous sickness, stay home if at all possible, and help in any way you can, those who need it.

We will all need to stand together (with a distance) to get through this. If we do, most of us will be there on the other side, if not, we will see much fewer people succeeding.
