Amateur Radio

Post  ian1954 on Sat Nov 08, 2014 9:33 am

As it brought back memories, I thought I would steal this from another thread

fredvon4 wrote:Well done Andrew. Good safe design and very neat engineering of layout and box.

As a Ham Radio operator I have several AC to DC power supplies but all are either store bought or purpose built (by me) to maintain constant current to keep the transmitter finals happy.

I fondly remember building several Heath Kit projects in the 60s with my dad and he stressed to me the importance of "neat" and efficient construction/layout.

It is back to the 60's when I passed my Radio Amateurs Exam and got a call sign (code) that allowed me to transmit on the 2M band. Short distance but remember this is pre mobile phone nonesense! There were strict rules about what you could and couldn't say and it had a language (acronyms) of its own.

About a year later, I passed the morse code test (it took me ages to master it!) to allow me to use the higher frequencies but I could not afford a transmitter - I had an ex military receiver.

It was a struggle to qualify but this was quickly wiped out by, what was then, the illegal introduction of the "Citizens Band". Cheap oufits flooded the country and it was adopted by so many that it then became legal. THIS WAS THE DEATH KNELL FOR MANY MODEL AEROPLANES. They operated on 27MHZ and interference was rife. "&MHZ was then only allowed for model boats and cars. Aeroplanes had to move to 35MHZ. There was a lot of ill will at the time - the "Citizens Band" was not policed and ...........

I never went back to it but do remember "Heathkit" and all the magazines (now disappeared into oblivion!). Heathkit kits were available from Tandy (this was the name given to "RadioShack" in the UK. These shops had many delights for "hobby" electronics constructors - kits, components - knowledgable staff ....... Tandy disappeared from the streets here many years ago.

I continued to visit RadioShack on my trips to the USA but now they are just mobile phone and toy stores! I looked in the one in Chicago on Thursday- don't know why - I am always disappointed!

I was delighted to see that there are still "Hams" around. In the 60's, you could spot a "Ham's House" by the aerials - ranging from wire stung between poles to all sing and dancing motorised Yagi. Not seen that for years.

Thank you Fred for the trips down memory lane!

Ian

As noted I am perusing old threads and found this one

I am not set up now with ANY antennas ( past storms and no real passion to fix)

But some years from now I will be too infirm to play model airplane, and would hope to find some like minded guys, like you, from my arm chair on 20, 40, 80 meters voice

Jest a thought

I have often thought of this and the equipment is now very cheap compared to 45 years ago.

http://radioworld.co.uk/used_ham_radio_equipment/hf_transceivers

I looked at my last post and how time passes. Radioshack is no more.

I also remember that arranging conversations was a little "hit and miss" and depended on not only the weather but the time of day. We are talking a long time ago - so I did a search .........

Establishing contact is dependent upon

The distance from the transmitter to the target receiver.

Time of day. During the day, frequencies higher than approximately 12 MHz can travel longer distances than lower ones. At night, this property is reversed.

With lower frequencies the dependence on the time of the day is mainly due to the lowest ionospheric layer, the D Layer, forming only during the day when photons from the sun break up atoms into ions and free electrons.

Season. During the winter months of the Northern or Southern hemispheres, the AM/MW broadcast band tends to be more favorable because of longer hours of darkness.

Solar flares produce a large increase in D region ionization so high, sometimes for periods of several minutes, all skywave propagation is nonexistent.



Much easier these days to use "Skype" over the internet and get video as well! I have used this to and from the USA, India, Africa, Israel and China.

I too also bear in mind that age and health will be a limiting factor in pursuing our hobby.

Ian as much as finding a good for YOU and ME skype time may be relatively easy...I would dearly love, say 10 years from now, to chat with you using Amater Radio

after all I did spend the bucks for the equipment and time for the license

Not sure if in England you saw the Movie frequency or the new this year series along the same idea... Ham radio time shifted to the past and the associated changes to a time line by changing history... terrible writing, real bad Ham radio procedures, and obvious errors with equipment and antenna capabilities....but yet still good, mind numbing, entertainment....grin

I've always been interested in radios and transmitters going back to when I was quite young. I occasionally have the scanner on (2m band) to listen to the local guys discuss weather, electronics, events and other stuff. If I ever get the time, I'd like to get a technicians ticket. There's been many times that I'd like to add my Two Cents to the conversation.


RadioShack is pretty much done, most of them closed up around here. They had little to nothing of use anymore. If you ever make it to the Twin Cities, stop in "Radio City" in Mounds View, you'll have fun in there. They refuse to sell any transmitting equipment or accessories without a ham license (although there is no law against it). Also check out AxMan Surplus, they have a few locations around the city. Lots of good stuff in there.

The same descriptors work precisely for ANY TV series involving ANY airplane subject matter!!!

I dearly hope Ian sees this post

I have firmly decided to sell off ALL my Amateur radio equipment and sadly leave that hobby in the distant past

For me it was always a struggle --as I am NOT a smart person... IQ or education wise...to get Antennas and radio gear to be relibale

I just spent an unpleasantness 5 days trying to get a new cell phone to behave....that said, internet helps so much I can not deliberately consider an ancient communication method worth MY time

SO..Ian (England) and any other Germany, Budapest, Singapore, or Australia guy who wants to chat... it will be on current state of the art sat/internet/landline/skype type connections

The KD5NCO call will be relevant only until it needs renewal...NOT
BUT PHRED is NO longer on 40 or 80 meters
