Yaesu FT101 restoration

The Yaesu FT101 has appeared in several versions since it first appeared way back. This is part 1 of a restoration project on a very old version.

Spring - NOT amateur radio

Tomorrow is the first day of meteorological spring. 

I always look forward to the first swallows returning from Africa on migration. They usually arrive here in mid April, although they are a bit earlier in Devon.  Swifts, that we see more of, arrive about mid-May. These are often heard screaming before being seen.

The first to arrive in Devon are the sand martins, which usually are seen in Devon mid March. I recall my dad telling me when he first saw some on his golf course.

"Sunsetting" - NOT amateur radio

Google Adsense amazes me. The phrase that they have come up with to say they are ending something is "sunsetting"  which is a way of saying stopping! They always use a turn of phrase that disguises the real meaning, making it sound something good.

So, if you want to say something is stopping, it is "sunsetting"

Cleaning the car - NOT amateur radio

Our neighbour across the road cleans his car every week. We clean ours when it gets embarrassing.  Judging by the moss, this must have been several months ago! 

Yesterday I washed the car.  😂

Experiment continued - 10mW 10m WSPR (Friday)

Today, I am concluding my experiment with very low power on 10m. Today, I am running 10mW 10m WSPR. Conditions are more disturbed than yesterday. 

UPDATE 1654z:   14 spots of me so far today. I think my experiment has demonstrated that very low power digital modes really do work on 10m. WSPR is better than FT8, but even 10mW of FT8 can be enough, although you need a clear frequency!   Back to QRO (3W HI) tomorrow!

UPDATE 1910z: 19 spots of my 10mW WSPR today.

Sunspots - Friday February 28th

 Solar flux is 170 and the SSN 129. A=32 and K=4.

AliExpress

This is an outlet for Chinese (only?) companies. I find some of their prices remarkable. Often the goods come by air in just a few days. On some items I guess you might have to pay some duty. Even so, their prices are unbelievable.

I suppose the downside is that this kills western manufacturing that cannot compete with labour costs. Making in Europe or the USA we would not be able to compete on price.  Making consumer goods more locally would stoke inflation.

Two radio rallies this weekend

On Saturday we enter meteorological spring and rallies occur more often. The following have been notified to me, but I always advise to check before going far.

• Saturday March 1st - The Lagan Valley ARS Annual Rally, Hillsborough, N. Ireland, BT26 6AE. See www.lvars.uk
• Sunday March 2nd - Exeter Radio Rally, new venue, The Kenn Centre, EX6 7UE.  Contact g3zvi@yahoo.co.uk .

Local club talk, without talking

As mentioned before, tomorrow night (Friday) at 2000z, I am giving a talk on 8m at the Cambridge Radio Club. As my voice is poor, someone else is doing the speaking even though I prepared the slides and notes. We did this last year and it worked. I am sure if you are not a regular CDARC member you would be welcomed as a guest.

10mW 10m FT8 (Thursday)

My gear was turned on at about 0915z. I am using the IC-705 at 3.2% power with a 15dB commercial RF pad right on the output. No spots yet although I am copying plenty of Far East stations on 10m FT8 RX despite the 15dB pad inline. I suspect with QRP you are more likely to be in the (local) noise or underneath a stronger station, so chances go way down. Given a low noise floor and a clear channel I am sure it would be possible at 10mW. As a reminder, my antenna is a low end-fed about 3m above ground. With the antenna higher and/or with a beam better results are assured.

UPDATE 1209z:  Still no spots on 10mW 10m FT8 TX, so I have QSYed in case I am being clobbered. On the evidence so far, 10mW FT8 is just too little. 100mW was fine. As the sunspots decline I think I will use 2-3W FT8 from the QDX on most occasions. It would seem the 10dB more reduction on FT8 TX power makes it hugely harder. I guess WSPR is better as it takes up less bandwidth (less chance of being clobbered) and works with signals far weaker. Maybe I should try 10m WSPR TX tomorrow at 10mW?

UPDATE 1440z:  Spotted by 2 stations when running 10mW 10m FT8. It is much harder at very low power. I suspect it would be far easier on 10m WSPR with its much smaller bandwidth (about 6 Hz rather than about 50 Hz) and far better sensitivity. WSPR can decode signals probably about 10dB weaker than those on FT8.

UPDATE 2144z:   QRT. 10mW 10m WSPR tomorrow.

Healthy breakfast - NOT amateur radio

Mid-week and at weekends I enjoy a cooked breakfast, but I try to eat healthily for breakfasts on other days. 

My typical breakfast is Weetabix with fruit.

Sunspots - Thursday February 27th

 Solar flux is 180 and the SSN 123. A=16 and K=4. 

17m super-DX

 A local friend of mine reports that he has been spotted in South Australia with just 2mW WSPR on 17m. It goes to prove that not much power is really needed!

Really? - NOT amateur radio

Promise - NOT amateur radio

We are coming to the end of winter and there is a hint of spring: days are getting longer, snowdrops are out and the daffodils are not far behind. 

100mW 10m FT8 (Wednesday)

My gear has been on since before breakfast.The IC-705 power out is set to 1% (100mW).

UPDATE 0920z:   So far, spotted by 17 stations! QRP? Easy!!

Stations spotting my 100mW 10m FT8 at 1320z

UPDATE 1326z:  78 stations have spotted my 100mW 10m FT8 including many in the USA. I can't say running just 100mW is really such a handicap. 5W sounds like real QRO!! Furthermost is W5LOR (7629km).

UPDATE 1545z:  131 stations spotting me in 5 continents on 100mW 10m FT8. With an external attenuator, I think I can go to 10mW 10m FT8.  Actually with my 15dB attenuator I could go even lower! 

UPDATE  1604z: Just added 15dB pad to output. Output is now 3.2mW. No spots, so this might be too low, especially if clobbered by a stronger station! Lots of stations still being spotted on 10m FT8 RX even with the 15dB attenuator.

UPDATE 2045z:  QRT. No spots at 3.2mW. Tomorrow I shall try 10mW.

DXpedition

 In the summer is a DXpedition to this Pacific island.

Sunspots - Wednesday February 26th

 Solar flux is 180 and the SSN 155. A=16 and K=3.

Amaryllis - NOT amateur radio

We have had amaryllis plants in flower all the time from November and we still have some still to flower!  

My wife made this collage.

Church abuse - NOT amateur radio

It is saddening that the Anglican and Roman Catholic churches in the UK seem to be untrustworthy when it comes to sexual abuse. 

I know personally of one Anglican priest who was moved on to another parish rather than being sacked after having carried out sexual abuse. He carried out abuse against minors (not me!) and was moved to another parish.

It is my view that this sort of thing is widespread and the churches are more concerned about themselves and less concerned about the victims. A similar situation seems to be the case in the Roman Catholic church in the UK.

You would hope that all churches could be trusted without question.

In my view any safeguarding investigations absolutely must be independent.
