Santee Lakes is not part of the City of Santee. It is owned and operated by Padre Dam Water District. I have done a search of the FCC ULS and may have located the freqs. I'll know for sure the next time I go there.
I'll try these, but the freqs I found were all VHF and UHF conventional. Some of them had the Mast Ave. address for Santee Lakes. I'll be at the lakes either this weekend or next agian and try everything. Thanks for the info.
