Any one have some experience with SPR radios? (Secure Personal Radios), similar to PRR methodology, but not in the 2.5 GHz range and generally higher encryption. I've seen some with the ultra-low broadcast power and automatic repeater of all the radios ("mesh" style repeaters) or higher power, non-mesh-repeaters.
I've been looking at the
Relm RP 3300 series (specifically RPU3300A), as it's exportable (Stupid ITAR) with AES 256 bit encryption, 450-470Mhz, OTAR, and I think P25 (Phase 1?) compatable (it's talked about, but it's not on their spec sheet). But there is a bit of sticker shock.
Just wondering if someone has found a high quality, lower priced alternative here?
