[HomeBrew] Homebrew VHF FM Monitor Receiver

[Dennis L. Wade]

Hello everyone,

	I've been wanting to set up a bank of dedicated FM monitor receivers 
for our highway patrol (dual channel 46 mhz) and a couple of 
repeaters on 6 and 2 so I can have them up at a touch of a button and 
not rely or tie up a scanner for them.  The highway patrol here uses 
separate frequencies for base and mobile, so each "channel" is 
actually a pair of frequencies.  I would want the ability to add a 
subaudible tone decode function to it.  No other odd 
features...crystal control preferred, squelch, respectable 
selectivity (I'm in an urban area).

	This looked like a nice project to do myself, but I'm having 
difficulty getting a design in hand.  A Google search revealed a 
design that looked good until I realized that it uses a chip from 
roughly 10 yrs ago, and the chip (MC3353 in think) is no longer in 
production.  Another chip, MC13135 apparently is current (?) but I 
didn't run across a design with it. (Both Motorola of course).  

	I'm not wedded to any particular technology, so a "vintage" design 
is fine as long as I can get enough parts for about 8 receivers 
(though I would draw the line at tubes in this application...hehe).  
The ARRL handbooks from the mid-70's had a 2 meter receiver that 
would be ideal if I could find enough parts for it today.  

	Am I looking at a design using surface mount components these days?  
Is homebrew with SMT practical?  Special tools I need if I have to go 
SMT?  My breadboard skills are OK if a little rusty.  

	Thanks for your collective wisdom...
