I have a 3530 too, and it's a great radio but mine has a problem with the
squelch. Anyone happen to have a service manual they'd loan?
For aux link use, probably the cheapest way to go is do a Mastr II PLL
conversion and skip the PA (but do use a LPF or at the very least a BP
cavity, give a hoot, don't pollute). A hundred mW or so is often enough for
line-of-sight paths. Quick math says 30 miles has about 113 dB path loss on
222 MHz, so 100 mW (+20 dBm) with 5 element yagis (8 dBd) on each end should
give you -77 dBm (about 30 uV) ignoring feedline loss, plenty of oomph.
