Re: Topband: VU2 on top band
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?

Re: Topband: 160 Power
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. 73 vu2gsm Kanti > On Mar 21, 2017, at 05:42, John Harden, D.M.D. wrote: > > If you want to work the rare ones on Top Band low power is pointless...
