A friend sent me this.
I'd been wishing I had the time to get one of these & do this.

You mentioned taking apart a handheld at one point, and modifying it.
Looks like someone did this:

All the of the frequency response and modulations/demodulations happens
in the RDA1846, which is basically a SDR with a DSP to do the
modulations/demodulations. The RDA1846 has a fixed frequencies and modes
that it will RX/TX on, and its controller by the MCU
(http://sdr.ipip.cz/datasheets/RDA1846.pdf ). I was going to try to mess
around with the VCO of the RDA1846 to see if it can handle other
frequencies (but its not made to work on frequencies other then the ones
its made for). However, the RF amps and filtering on the chips are only
made for the 2M/70cm band.
