I remember in the 70's when 3amp power supplies cost a fortune a

Gareth McEvans?

naw local to Glasgow....a G8 .......professional ....


Yeah, that's the bloke. He moved away and (after a bit of a
struggle) passed the morse - I wonder where he is now...

you remember who I am talking about then? ...


GM8D something? The shame was a bit much for him, hit the bottle? Spent
years trying to find a 'sympathetic' morse examiner so that he could
scrape a pass?

Rings a bell. Did he end up having a run in with the law in the end?

But it does raise one question, and that is, who is fooling who about
its purchase price of ooo £450, for there cannot be more than about
£40
in its component costs?

DDS modules, £8 ea

SA612 £2 ea

PIC processor, anything from £2 to £20 ea.

Double-sided PCB for ugly-bug construction, £5

If you did iit like that the circuit would be about a foot (ancient
American unit) across and wouldn't work.

Sorry, Grandpa, but the numbers above do not refer to valves (tubes to the
Yanks)
such as the 807, or, in your own case, bearing in mind your 50-year-old
second class Class B licence, such as the QQV03-20A or 4CX250B.


Ugly bug construction requires only a little more space than the devices
themselves.

Well I bow to your superior skills. I have never seen 'dead bug'
construction with SMD passives in large numbers, and four sided IC
packages with sub -millimeter pin spacing. I found just hand-soldering
the DDSs to the multi-layer circuit board sufficient of a challenge!

I'd never really understood the depths of your idiocy before - thanks
for the clarification, Gareth!

happy new year!

Not when the majority of devices are SMD.

Not much good when you need low inductance or low cap. circuitry either.

Evans is simply demonstrating his lack of practical experience.

Well, passing the 12WPM Morse test shows that I do have the right moral
fibre
of true dedication to the pursuit of amateur radio, unlike those who whinged
about it for 30+ years and then went for a test and a licence targetted at
5-year-olds.


But, enough; rise off your knees!

Nope, just shows you are can be trained in simple skills.
