Pye Telecom - NOT amateur radio

In my working life I worked at Pye Telecom, later Sepura, retiring in 2008. You may be interested in Pye Telecom. Most of the products were PMR radios for the police and similar.

The photo shows my pass when I was at Philips Paging in California back in the late 1990s. I worked for Philips Paging for a few years. Unlike Private Mobile Radio, pagers were consumer products. We made more in one night than we made certain PMR products in a product lifetime. Every penny really really mattered as did the slightest of blemishes. We made pagers in Cambridge, Mexico and Singapore.

Start them young?

Looking through some old photos I came across this one taken in 2013 at the old QTH showing our grandson, who is now 13, in my workshop at the time in the back of the garage. 

At the time he must have been pretty young.

10m FT8 RX

At 0720z I turned on the FT817ND and indoor loop on to 10m FT8 RX. In the last few days my results have been disappointing. I suspect the loop is quite a bit less efficient than a dipole.

UPDATE 0847z:  G0FWX (160km) spotted. As he was quite strong, I wonder if this was aircraft scatter

UPDATE 1330z: 4 stations spotted with some Es in the form of IK7LJZ (1664km).  After comparing my RX results with G0LRD who is using just a low dipole on 10m, I think my loop must be at least 6dB down.

PC, FT8 and IC-705

Thankfully, I have managed to locate (in the house) a lead that connects the PC to the IC-705, so may be able to try communicating later. This can only be to see if it works as I need the wire for other things. I shall have to buy a suitable cable longer term. 

The function of the new icons has been found after reading the manual again. One is speech recording and the microSD symbol flashes when it is being used. Possibly some of last night's 2m net is recorded?

Blossom - NOT amateur radio

 

The photo shows fallen blossom on a path a few years ago.  It was one of my FaceBook memories.  Most blossom has now fallen. Spring is one of the best times of the year with fresh green leaves, daffodils and blossom. It is as if the earth wakes up again and bursts forth.

Testing times

The photo shows me testing my 481THz optical gear 8 years ago. I have not tried optical work for some time. My interest was over the horizon beaconing and I was surprised by how far I could detect the signal with absolute absence of anything visible in the sky.

IC-705 firmware updated

Following the instructions in "The RadioToday Guide to the IC-705", I have successfully upgraded the firmware from V1.12 to V1.24. All appears to have gone correctly. The next thing is to get a suitable interface cable from the rig to the PC and try FT8 and rig control.  Some have used cables with ferrite toroids on or isolators to minimise ground loops.

As you can tell, I am taking things very slowly. With my "brain fog" (probably as a result of my 2013 stroke) it is all too easy to make mistakes. Jobs that would once have seemed trivial are now quite hard. Even just unpacking the microSD card from the packaging was a challenge!

UPDATE 2029z:  Since doing the firmware update, a couple of new icons have appeared. The SD card is there, but flashing (why?) and there is an adjacent red circle. I am sure I shall find out what these are soon! I was able to have a 2m FM net OK this evening, but avoided touching anything just in case it all went wrong!  Investigation needed, HI.

Church clock - NOT amateur radio

It is comforting to hear the church clock chiming again. Sadly, the chimes are about 13 minutes early! I am not sure how old the clock is. 

The main tower bells have not been rung very often in the last year. When they return we will be back to "near normal".



Shack video

 


Some years ago, I did a video about the setup here. Sorry my voice is so poor!

NASA's Mars helicopter flies - NOT amateur radio

NASA has successfully test flown its helicopter on Mars.

Nostalgia time again

Since the 1960s we have come a very long way. Back then, I thought G4PJ's AT5 from Codar was amazing (see photo). This was a valve 160m/80m AM/CW TX putting out about 10-12W.  There was a companion RX, the T28, which was dreadful.

These days, you can buy a whole SDR transceiver covering 160m-70cm with all modes plus Bluetooth, WiFi and GPS in much the same size.  Mind you, the AT5 was a lot less expensive!

See https://sites.google.com/site/g3xbmqrp3/at5 .

10m FT8 RX

At 1030z, I turned on the FT817ND with the indoor loop on 10m RX. Comparing results with G0LRD, I think this antenna must be several dBs down. I can't wait to erect a 10m antenna outside again.

UPDATE 1236z:   No spots.

UPDATE 1301z: Just G0LRD spotted.

Geosynchronous Oscar 100


Every few weeks I check activity on the narrowband transponder of this satellite by looking at the web SDR at Goonhilly. The last time I looked was just before 0800z on Monday. 

My impression is activity levels are still low. As I have said before, this is just a quick view and far from scientific. If I looked a few minutes before or after, I might have formed a different view.

See https://eshail.batc.org.uk/nb/ .

Grandchildren - NOT amateur radio

Like many, we enjoy seeing our grandchildren. We were fortunate to see them all over the last few weeks. Many grandparents overseas have been less fortunate. 

The collage shows them in the last few weeks.

DXCC entities

Long ago, I stopped chasing DX. If I work some rare country or QTH square then great, but I do not chase it as if my life depended on it. There is always tomorrow, but if it "gets away" does it really matter? This is just a hobby. Personally, I like to see where my QRP signals reach, but each to their own. There are many ways to enjoy our hobby.

To some working every entity matters. They enjoy the thrill of the chase. I see Southgate News has a link about this. Apparently there 209 DXCC entities active.

See http://www.southgatearc.org/news/2021/april/dxcc-country-entity-report-19-04.htm#.YH0zZSjYrrc .

French proverb - NOT amateur radio

 "To understand all is to forgive all".  

I believe this is an old French proverb, but what a good one.

I am of the view that there is good and bad in all of us. Most things that go wrong whether personally or globally are as a result of not fully understanding the whole picture. It is all too easy to judge when we only see part of the picture.

IC-705 firmware upgrade

The micro-SD card for the IC-705 has arrived. Tomorrow, I may try a firmware upgrade. Others tell me this is straightforward. I certainly hope so!  I am not sure of the latest firmware (1.24?), but I am sure I shall find the latest on ICOM Japan website.

2m FT8 QRP (Sunday)

At about 1900z, I QSYed to 2m FT8 with 2.5W and the big-wheel omni antenna. It is now 1915z and I have been spotted by 5 stations on TX and I have spotted 4 stations on RX.

10m FT8 RX

At 1419z, I turned on the FT817ND and the indoor loop tuned to 10m  As yet (it is now 1432z), no spots. 

The sunspot count is slightly lower than yesterday and conditions more disturbed.

UPDATE 1730z:  Just G0LRD spotted here and on PSKreporter by me. A PY seen mid afternoon, but this doesn't appear on PSKreporter. Overall, this has been disappointing. I'll give it a bit longer before QSYing.  Looking at all the results David G0LRD has got (111 10m spots!!) he is certainly being widely spotted on 10m FT8 today. Not sure what David is using for antenna and power.

If you are looking for a 10m grabber, check this one out in Alaska at http://kl7l.com/28Alaska00000.jpg . If you know of others, please let me know. I see there is a 10m QRSS grabber at https://qsl.net/g4iog/ .

The 4m (70MHz) band

 

At one time very few countries had access to this band and there was no commercial gear.  Now it is widely available, especially in Europe and several transceivers now include 4m.  One place for data is the 4m website that has quite a bit about the band. It is some years since I was active on 4m.

In Es openings, many European countries can be worked with simple antennas and low power. One possibility is my simple transverter.

See https://70mhz.org/ .

Homemade pasties - NOT amateur radio

Don't laugh. 

This morning I felt inspired to have a go at making some pasties using up some of the food that might have been wasted. I am quite pleased. The photo shows the results. Mostly cheese, mushrooms and onions. 

They taste good too.

2m FT8 QRP (Saturday)

At 1820z, I QSYed to 2m FT8 QRP with 2.5W and the big-wheel omni antenna. So far (it is now 1830z) 3 stations have been spotted on RX and 6 stations have spotted my QRP TX.

See http://82.71.9.63:8080/cap/ . This is the FT8 grabber at G0LRD.

Anglesey Abbey - NOT amateur radio

These flowers were seen at Anglesey Abbey a few days ago. My wife did the collage.

Royal Funeral - NOT amateur radio

Like millions around the world, we watched the funeral of the Duke of Edinburgh from Windsor Castle. 

I am not a great royalist and cannot imagine the royal family surviving another 50 years unless it changes. When the queen dies the English royal family will be in mortal peril. No, I think what was really being mourned was the end (or very near end) of an era.

Privilege, as a result of who you are, will end. Minor royals who live wealthy lives off UK taxpayers will end. I think the royal family has to evolve. I cannot think of a suitable president should we become a republic. No, I think we will still have a royal family, but very different.

I feel very sorry for the queen who has lost a lifelong husband and companion. They we married for 73 years, which is a long time!

10m Phaser FT8 kit

Apparently, this 4W SSB kit designed for 10m FT8 is about to ship from the USA. Being designed by Dave Benson, K1SWL, it should be good. All SMA parts are already fitted.

As well as my DSB rig, the 10FT8R, this is a project I must build.

Yet more incentive to get my external 10m antenna up!

Twente SDR

My very first post was about the web SDR at Twente in the Netherlands. That was in 2008! It is still there.

See http://websdr.ewi.utwente.nl:8901/ .

10m FT8 RX

My 10m FT8 gear (2.5W to the indoor loop) was turned on at 0808z. After a very brief TX period, I am on RX only. So far, no spots.

UPDATE 1018z: Just G0FWX (160km) spotted so far. No Es or F2 propagation evident here yet.

UPDATE 1120z: 7 stations spotted. Looks like Es to Iberia.

UPDATE 1700z: 11 stations spotted today. See the log for details including one from Brazil.

Loops

As you may know I have had a good deal of success with tiny indoor loop antennas. The photo shows the loop for 10m. 

At the moment I have no HF antennas outside, so I do not know how well my loop antennas compare with "real" antennas.   

All I can say is the loops work much better than I expected.

Home video conversion - NOT amateur radio

Like many, we had lots of VHS and Video 8 tapes, but no way to play them! A few weeks ago I had these converted to DVD. Later today I hope to copy these to the PC as a backup. Later, I will copy these to flash drives for our sons who feature a lot. Many of these have not been seen for years! 

We should have done this years ago, but I suspect, like many, we were nervous of sending these precious memories away. What if they were lost? 

In the end, we used a company called EachMoment who were excellent. At every stage of the process we were kept informed. The resulting DVDs came back with the original tapes about 2 weeks later. Thankfully, even after all these years, they copied fine.

I would have no hesitation using them again.

Haircut day - NOT amateur radio

On Wednesday I had my hair cut in the garden by my son as the photo shows .  My wife had her hair cut too at a local salon. 

Shack some years ago

The photo shows my shack some years ago. I am a dedicated QRPer and rarely use much power.

At the seaside - NOT amateur radio

 

The photo shows one of our granddaughters eating chips on the beach at Felixstowe today. 

Looks like they have good weather.

Another cancelled rally

The Hack Green rally, due this Sunday, has been cancelled. I presume this is as a result of Covid.

70cm FT8 QRP

Last evening there was a 70cm FT8 contest. For most of the time I was on my V2000 vertical antenna with 2.5W. Quite a few UK stations were spotted and I worked one. I wonder if some were spotted by aircraft scatter? 

Clovelly, N. Devon - NOT amateur radio

In 2012 we went on a holiday to North Devon. Remember holidays 😉? The photo shows the village of Clovelly.
