No 23cm in Finland?

According to a piece in Southgate News, amateurs in Finland lost the 23cm band (apart from temporary access by special permit) back in April. They are seeking alternative spectrum, possibly the 220-225MHz band that is allocated in the USA. The prime driver is amateur television.

The authorities are concerned about future interference with Galileo navigation satellites. It is a pity they could not have retained access to 23cms, perhaps with a much reduced ERP on a "non interference" basis. 

As far as I am aware there are no similar plans across Europe for 23cms. If the Finns get access to the 220MHz band, I think this would be the first in Region 1. 

Personally I would have tried for low band 1, possibly including the 8m band, say 40-45MHz. The bottom could be narrowband and the rest for DATV on a secondary basis. Even if they only allocated 2MHz, this would be useful in under-used spectrum.

6m FT8

At about 0930z, I went on 6m FT8. Although I briefly went on TX (2.5W and the V2000 vertical), I am mostly RX only. It would be great to spot anyone!

UPDATE 0950z:  Remarkably, G0PQO (50km) spotted my brief 6m FT8 CQ earlier. Nothing spotted on RX.

UPDATE 1332z: 1 G station spotted.

UPDATE 1845z: 3 G stations spotted. 

UPDATE 2052z: At 1915z I returned to QRP TX. Nobody has spotted me this evening.

6m E layer super DX

The blog of John EI7GL reports on some astounding DX on 50MHz (6m). Although reported as multi-hop Es, I have my doubts. This is like the super DX seen every June between Europe and the Far East. 

My theory is this is E layer propagation but, importantly, not sporadic E. In my view, at least some of these very long paths are the result of some sort of chordal hop E layer propagation. The EU to Far East June 6m openings are at the time when mesospheric clouds are often seen. I wonder if this was the same in the southern hemisphere? Any thoughts?

Winter, late afternoon - NOT amateur radio

 


This delightful photo was taken by our sons a few days ago. It shows the setting sun and one of our granddaughters.

2m FT8 QRP (Monday)

At about 1910z, I QSYed to 2m FT8 using 2.5W and the big-wheel omni antenna. So far this evening just 1 spot of me and nobody yet on RX and no QSOs.

You can almost imagine him thinking, "if only someone invented a microprocessor or an SDR receiver". 

Calendars - NOT amateur radio

Every year about now we make calendars for the next year.  These are examples.
