Sunspots - Thursday April 9th 2020

Solar flux is 70 and the SSN 0. A=13 and K=1.

FT7 series

Back in the late 1970s I owned an FT7 transceiver. This produced 10W and allowed me to work all over the planet, mainly on 10m SSB. Contacts included New Zealand, which was about as far as possible. All these were with low wire dipoles - no beams!

Later Yaesu sold the FT7B, which was a higher power version which covered all of 10m. I never owned one of these. About 20 years later you could buy the FT817 which was a 5W portable including 6m, 2m and 70cm as well as FM.

More signs of spring - NOT amateur radio

In these strange days, we try to keep a routine by doing a daily walk. We see very few people and those we do are very good about social distancing. This tree (see photo) is another sign of spring.

Although there are swallows in Devon (migrant birds), I have yet to see any here in East Anglia.

The 2m SSB Liner-2

If you were around in the 1970s, you probably remember the Liner-2. This was the 2m rig that brought 2m SSB to the masses. I had a second-hand one and recall being amazed by how far I could reach.

With a simple loft antenna (HB9CV I think) I could reach stations totally out of reach on QRP AM.

The Liner-2 was a synthesised rig that produced lots of spurii if over driven. In the end mine was sold and replaced by an ICOM IC-202 as I recall. In its day, the Liner-2 was ubiquitous and a "must have" rig for serious 2m operators.

Adverts I hate - NOT amateur radio

Not sure if this a recent thing, but I am seeing more and more ads that say something like, "UK seniors over 50 are rushing to get this new....".

They are written in such a way that your interest is raised, so you are tempted to take a look. Whenever I see this I do not look. Although most are probably virus free, they are clickbate. Personally I hate these.

Early start on 20m FT8 today

At 0620z I was on 20m FT8 with the tiny indoor loop and 10W. No spots of me yet but one CT copied (0630z) .

UPDATE 0810z:  Although 20 stations so far spotted on 20m FT8 RX, (best spotted here is JT1CO (6662km) in Mongolia), no spots yet received on TX. It appears I was only using about 5-6W, so this has been increased and the frequency moved in case I am being clobbered by a big station I cannot see.

UPDATE 0836z: Just 1 spot of me so far today by UT4EX (2464km). 25 stations so far spotted on RX.

UPDATE 0903z: With 32 stations spotted so far today on 20m FT8 RX, the tiny loop is performing well. On TX I am sure the main problem I have is being obliterated by stations co-channel with me that are much stronger. When the frequency is clear, my 10W tends to get spotted by loads of stations. The trouble is I do not know when this happens as often these signals are not visible here. I always choose, what I think are, free frequencies.

UPDATE 1450z: 27 spots of my 10W so far today.

UPDATE 1747z: The map shows where I was spotted today on 20m FT8 TX with 10W and the tiny indoor loop antenna.

Sunspots - Wednesday April 8th 2020

Solar flux is 70 and the SSN 0. A=4 and K=2.

iPad question - NOT amateur radio

Although Steve G1KQH kindly solved the problem of my wife being unable to email photos from her gallery, we still have the mystery why the battery now seems to drain so much faster. This suddenly changed.

Although I cannot be sure, it does not seem to be the cells.

I am wondering, as an experiment, if there is a way of loading older software versions to see if this change is, or is not, linked to a software change.

Village walk - NOT amateur radio

This morning we did a nice walk around the village. We covered about 3 miles. We saw 4 buzzards but we have still to see any swallows. The photo shows some of the flowers we saw.
