Shopping - NOT amateur radio

Most weeks we go about 12 miles on the bus into Cambridge. As we are old (!) we have free bus pass, so the journey is totally free. It is also as fast as taking our car. It is a pleasurable ride too.

Like most men, I hate clothes shopping. Instead I had a coffee whilst my wife did the spending!

OXO QRP TX


This circuit was originated by GM3OXX, hence the name. It has become a classic circuit. It produces about 1W CW. It has been built by many people in many forms and is very easy to replicate. You just need to add a low pass filter for your chosen band. I have used it to 10m.   This schematic was on the G3PTO website many years ago.

10m QRP WSPR TX (Tuesday)

Once again I am on 10m WSPR with my 500mW beacon. It is now 0820z and, so far,  20 stations spotted. Some are F2 and some Es. A very promising start.

UPDATE 1449z:  52 unique stations have spotted my 500mW today so far. Pretty encouraging.

UPDATE 2052z:  54 stations spotted today. Some would have copied me with just microwatts given a quiet noise floor.

8m QRP FT8 (Tuesday)

As the Es looks promising, I am again on 40.680 MHz FT8 (TX 1st, DF about 1950 Hz).  No spots yet.

UPDATE 1452z: 
  My 2.5W 8m FT8 spotted by 5 unique stations so far.

OFCOM and my requested 8m T&I licence changes

I sent an email to Dave Parsons at OFCOM, who has always been quick and helpful. Within 24 hours he came back to me for some clarification. Hopefully, he will unblock things. He is one of the better people there.

UPDATE 1333z:  Just a day after contacting Dave, my licence has been amended so I can run 20W if I need/want to on 8m.

Yaesu FT-710 versus ICOM IC-705

My IC-705 was traded in some months ago for the Yaesu FT-710. Both are excellent radios and I have enjoyed them both. The FT-710 has 4m but no 2m or 70cm. The FT-710 also has an auto ATU which I find quite useful. The FT-710 is a 100W  radio whereas the IC-705 is a 10W radio (5W with the attached battery). As a QRPer, 10W was more than enough for me.

I was hoping that Yaesu would announce a new QRP SDR transceiver at Dayton as a proper replacement to the FT817. Sadly, no such product was announced. Had one been announced, I might have traded it for the FT-710.

In my view amateur radio is at a crossroads. In many countries, amateur radio appeals mainly to older males. As these age, fewer new rigs will be sold and magazines will lose advertising revenue from dealers. Some will get smaller, less frequent, or close. In my view, several larger manufacturers will leave the amateur radio market as they will be unable to make profits. My prediction in the UK is that amateur radio will cease to be a service supported by OFCOM. I can see (not many years ahead) when CB, ISM and amateur radio will all become a "free for all" as these generate no income and are unnecessary hassle. The watchwords will be "no interference".

European Es today (Monday)

 At the start of today, I had great hopes for Es in Europe. Sadly, certainly at the moment, things are not looking too great.  Hopefully things will get better.

Multiple lives - NOT amateur radio

We are used to thinking of time flowing from the past into the future and experiencing just one life from cradle to grave. 

However, we are only aware of one life, which is the one experienced now. It is equally possible that we could have been born on a different planet at a different time. We could have multiple lives, not one.

All we know is things are far beyond our imaginations. We are just humans with limited brain power.

Poplar fluff? - NOT amateur radio

My wife took this photo on a recent walk. It looks like poplar fluff, although I am no expert! On the ground it looks a bit like snow.
