[600MRG] Do you feel 630-meters is practical for ham use?

[John Langridge]

Hi Steve - 

Yeah I firmly believe that 630m is practical for ham use and even from small lots.  When I did the microantenna experiments in January 2014 using existing small antennas on 630m, the results were very reasonable to me for what I was testing.  But everyone has a different view of what success is to them so the next guy might scoff at being heard at -24db SNR 800km away using an 8 foot tall vertical.    

Look at WB5WPA / WH2XQC who is having nice results using a small loop (maybe 30 feet tall and 30 feet horizontal?) and hardline for caps in his small backyard.
This line of thinking in addition to a conversation I was having with another 630m jockey yesterday has me thinking about some related items but I will send those in a separate email in order to prevent the inadvertant derailing of Steve's original message...

good discussion!

73!

I remember as a kid using phono oscillators to broadcast about half a mile. :)
