If it were me and were looking for a static /M radio I would be choosing between the FT-450D (Good value for money) FT-857 or FT-891.
If size were not a factor I would buy the FT-450D I reckon.
I’ve worked 2E0WDX/M on a fair few summits on HF SSB and he always has a good signal, equivalent to the fixed G stations I may be working at the same time. Not sure what gear Vin uses radio or antenna wise.
My tuppence worth Mark - I suggest you look closely at those 3 transceivers… I have had an FT857 for over 10 years now, still going strong and it has suffered significant SOTA /P use.
PS Take a look at 2E0WDX/M Chaser logs - gives you a good idea of what is achievable from a mobile Mark…
