Jackson have more narrower AM RX
because of use SSB
crystal filter in AM RX
path. Dual clarifier can go from 0 up to +10KHz on TX
and separate fine clarifier knob for RX
only. My choice beacause of AM RX
Grant only with PCB PC-999 had dual clarifier, but not as wide as Jackson.
Grant has dual 2sc2312 final stage, can do NPC-RC and after that is AM
audio monster doing up to 40 Watts on AM
with about 170% of crystal crisp modulation and no flattops on the scope. I've done couple of them that way.
Jackson is low level AM
modulation, but sounds great on TX
Of course you can "rewire" AM
path in Grant to go thtough SSB
crystal filter byt it is not that easy to do.
