And as for "not being able to afford a transponder" - I have never heard so much nonsense in my life. How much money do you spend on flying per annum? Far more than the cost of fitting a small transponder I'll bet.
No actually Scooter Boy I don't, besides which where do you suggest I fit one in my small single seat cockpit? My hand held icom radio even had to be fitted down between my legs in front of the stick! There are rarely simple solutions to such complex problems, so think before making such sweeping statements. This subject has been debated to death but people still bring it up again and again ... getting boring now!
