I kind of looked at that too - it looks to me like the DSP functions are all defined and self contained in the RDA chip. I noticed they have a similar chip - the RDA1847 that appears to have the same functions as the 1846, but it has external analog paths in and out of the chip, too. They say you can use it with an external DSP - which would let you do whatever you want to do I would imagine. I wonder if the 1847 would fit in the UV5R where the 1846 is? You could bring the analog signal out of the box and into an outboard DSP. I've seen efforts to do DSP with the Raspberry Pi.

I never am ceased to be amazed by the creativity of people involved in electronic, communications, or computers. Oh what visionaries. Or hacks.

one hell of a 2m opening last night. picked up repeaters from sw tenn. to VE3 land over to PA

That's when you swing your horizontal beam at them, tune down to the bottom end of the band and toss some CW or SSB CQs at them. That's where the real action is when the band opens.

if only I had a beam.... im stuck with a boring ol jpole.
