The 70 watt amp might just get you in trouble if anybody authoritative is reading this. otherwise not a bad set up. Don't know about the antenna a I've no experience with that make.
Though I do agree SSB gives you a lot more 'Punch' than straight AM. it's only good if both stations are using it If you are on SSB and I'm on AM you are noise to me and likely the reverse (though if we are within a few hertz it might work)... I use SSB a lot on 80 and 40 meters.
And that West Mountain DSP speaker... Oh yes... That one is a first class product. It outperforms many of those thousand dollar ham radio DSP units.
On my way to a hamfest I am.
