Appliance operators never heard I never mind Q 

Only know about sealed black boxes 

When the Big Bang happens I/Q will not help much 

CW, wire and a cycle dynamo will do the trick

Get learning CW and collect some radio valves

Well, I for one would generate them as an I/Q baseband stream and upconvert using a quadrature converter.  Just as every modern piece of radio communincations equipment does.

No expensive narrow band filters or IF stages.

SSB and especially CW - just tooooo boring for those not yet retired

Killing amateur radio

Where are the youngsters

Embrace the 20th century now we're in the 21st

Never, never, never...rather I become friar and I go to a cloistered convent !

And for delight of those who use only the digital mode, this is the power supply of my HF PA.

DIGI MODES

Fall asleep over the keyboard

Go for Xmas Dinner

Go down the pub and get drunk

Sleep for a week

And

the rig still Belches out wspr or opera and is seen world wide, no rush back for results.

 

CW MODE

Fall asleep over the PA running 2 x 4CX 1500 tubes

A flash and a bang

Operator is Zapped and reduced to vapour

Signal never left the shack, no result

Operator SK SK

 

You can see why DATA MODES are preferred, there is no option if the operator of today wants to remain alive and is not in a hurry for results

 

Operators of today are sluggish and move in jerks sort of robotic and are more suited to chips and not daring like those of yesteryears that would glare at 200 Watt filaments with 10 Kilovolts on the anode and had to move fast to avoid a SK SK situation

 

I expect some old timers are also getting sluggish and moving towards Digital, the easy life which also prolongs the pension.

 

Merry Xmas and avoid Danger------think Digital
