Dave,
Congrats on the "New Grandpa Dave" status!
Oops! You're right (as well as a couple of others that responded to my
comment). I interpreted Fred's comment incorrectly. I was thinking more
about the random vs. scheduled concept than as a function of
frequency. He did state VHF - UHF random contacts and I was thinking
lower microwave contacts (903 - 3456 in my case). Certainly, making random
contacts on the microwave bands (even the lower microwave bands) are more
difficult (loud locals the exception) than with scheduled contacts in this
range. Random contacts on VHF and UHF (50 - 432) are even less technically
challenging - although I still get excited when I work a random 500+ mile
QSO on 222 or 432.
73,
Ed K3DNE
