Re: Topband: VU2 on top band

[vu2gsm via Topband]

Hello All,
It is 1800 -1825 khz.presently and there has been no change as on date.
Interestingly, during the last week 's contest I noticed no stations operating 
from 1800 -1810 khz.  ( only EU?. ). What are the band allocations , on Top 
Band,  for Americas?
Thanks

Re: Topband: 160 Power

[vu2gsm via Topband]

I fully agree with John. I have been running 100 watts in to a dipole on 160 
and all I am raising is electricity bill from years. Unless you have decent 
power on TB no use warming the chair.
