Several things...
?
For SSB 10hz is fine enough but at 100HZ not at all good.
I've used manpacks and older radios and 100hz does not cut it
unless both radios (both yours and the otherguys) reference
osc are spot on.? Usual case is they will not be.
?
The IC7000 will do 10hz tuning very nicely.? Its my primary
432mhz SSB radio and backup for all other bands.? I also
have for? 2m use a TT M526 (6M and 2M) and IC 251A
(2m only).?
?
?NOTE:? 2M SSB IS NOT CHANNELIZED.? The display on
most radios may say 144.2000 but I'll bet money they
are?actually not on frequency.? ?The fix is tune the
other guy in.? That's what the big knob is for.
?
Add the the above list a FT817 (with tcxo) and I reset
them or check them at least once a year and usually
I need to touch them to make sure they are within
20hz at 144mhz.
?
?
The indicated DIAL FREQUENCY IS NEVER the output
(or input) frequency unless the radio has a recently
calibrated TCXO.? Usual radio to radio variation? on
the band is 100HZ wither way (low or high) or more
by experience.
?
IC7000 dial? accuracy is only ok but its stability is good.
There is a menu option for correction but you need a
reference source (wwV at 10 or 20mhz) to set it correctly.
By correctly I mean to less than .1hz error.
