Hello all

I am in the process of designing a three-station seismic network for 
monitoring two volcanoes within 8 kilometers of my home. I already have a 
geophone buried at my house and am monitoring a nearby telemetered site. I 
would like to install two remote stations using geophones, low-power 
transmitters and Larry's amplifier board.

My main problem is converting the amplified seismic signal to a tone for 
transmition (the received signal will be decoded using Larry's decoder 
board). Does anyone on this list have schematics, internet links or know of 
anyone selling this encoding equipment?

Thanks for your help
