help prevent qrm
- 20m was a mess today, everyone planting on 076.
this is not necessary ! try this...
set in spectrum the jt65 DF axis option
freeze the program to 0, with tol to 200
tune whichever station you wish to tune by shifting
your dial to place the sync tone on 0
the 200cps tol will effectively give you a filter 400cps
wide around the other stations rf freq and it will not
decode anything outside the window, this eliminates lots
of qrm to you. if you rig cant quite tune that close, when
most of the other stations tones are withing that window
you can re-freeze
the idea is to not use a large DF and take up more space
than needed, and spread everyone out a bit.
300cps is more than enough to ensure no qrm.
