RF in the shack?

 As reported yesterday, I have an issue using my IC-705 on 10m FT8. There was no problem on 6m. 

It suddenly occurred to me that this might be due to RF in the shack as I use an end-fed antenna on 10m. Later I will try adding some RF chokes to see if this cures it.

What hope?

Earlier I was in Bury St Edmunds so I popped in to W.H.Smith which is one of the bigger UK stationers. They carry a selection of hundreds of different magazines in this store. I looked and looked, but failed to see even 1 radio related magazine. If you want magazines on PCs, tattoos, trains, etc, no problem. Casually find a radio mag? No way! Without the casual interest caused by someone browsing a radio magazine, there is little hope for the future of our hobby.

There is little hope for RF engineering too. Over 11 years ago I recall interviewing someone for an radio design job. This person had a good honours degree in a communications related subject, but I knew more at 14 than this person. Needless to say this person did not get offered a job. Frankly, I was appalled. Hundreds of CVs were read, but a tiny handful had any idea.

No, RF engineering is in crisis. In general the magic is no longer there for young people today. People who had good RF design skills are retiring or have already retired. People can no longer chance upon radio magazines or amateur AM QSOs as we once did as youngsters. Yes, times change. However, the future of RF design is in deep trouble, in my view.

Cellphones and brain cancer?

There has been debate for years and years about whether or not excessive use of cellphones increase the chances of getting brain cancers. I guess that prolonged use of a high power VHF or UHF handheld may pose similar risks?

According to Southgate News a judge in California has asked for a 2014 report to be made public. A quick read seems to suggest some sort of increased risk. Basically, this is all relative, but prolonged RF exposure is probably not good and is best avoided. Another argument in favour of QRP?

Shortage of RF Engineers? - NOT amateur radio

Southgate News has a link on this subject. When I was in the RF business most RF engineers were getting older and close to retirement. There were few RF engineers coming through leading to a crisis in the near future. A shortage of RF engineers is a real issue in any nation. In my youth, RF was magic: these days it is not seen this way.

UPDATE 1512z:  In a recent look in our local shop I counted 15 train magazines, but not a single radio magazine. No, RF (radio frequency) is not the magic it once was. When there are as many radio magazines as train magazines RF will again be seen as interesting! It goes without saying that gaming and PC mags are everywhere.

RF Cafe

This looks to be a very useful resource for both professional and amateur RF designers with lots of useful links, software and calculators available. See http://www.rfcafe.com/
