A non-trunking P25 handheld receiver wouldn't be of much use to most people.
It really only appeals to a very small demographic of potential users.
I've never been a fan of HF - Ghz range handheld receivers. The HF and SSB performance is always compromised by terrible portable antenna performance, the lack of bandpass filtering, overload (when connected to a decent HF antenna), phase noise and stability issues. IMHO, that's why the IC-R10 & R20 were never really very popular models.
Handheld DC to daylight receivers are overpriced paperweights IMHO..
Now, if AOR released an updated 8600D style base model with even just conventional P25, decent HF SSB performance and a user friendly UI, for ~$1k, that would probably sell quite a few units.
