I want to build a reciever to work in the high VHF range ~160Mhz, for transmitting digital data, I am considering using IC's because space is a premium. I am looking at using a Motorola MC3362 narrowband FM reciever. In the many books I have been reading they suggest using a phased lock loop and/or? duel modulas prescalers for circuits to work at high frequencies. The problem is that I don't understand what the PLL and prescler are supposed to do and I don't understand how they work. The PLL seems to allow multiple channels but that is not a requirement, does it offer superior frequency stability? The MC3362 also has two inputs to the first mixer, some example circuits use both inputs using a transformer for impedence matching, other examples use only one input (other input grouded) and inductors for impedence matching, whats the advantage of using the two inputs Vs one input to the first mixer? Thanks in advance for any help Andy. ------------------------------ Date: 13 Apr 94 02:20:29 GMT From: dog.ee.lbl.gov!newshub.nosc.mil!crash!techtom@ucbvax.berkeley.edu Subject: 1750Hz tone on a Kenwood TH-28A? To: ham-equip@ucsd.edu I have a Kenwood TH-27A and TH-28A that I would like to use in Europe. Is it possible to Mod these radios to act like a "E" version? I.e. generate a 1750Hz tone during transmit? I don't care about switching back, since the radios will be in Europe for about three years.

After playing with both of these and the Icom and reading the QST review I bought the Alinco DJ580T. It does most all of the things that the others do, but it is cheaper and I found it easy to program and easy to modify. 73 de K3FZT (Steve) -- Steven J.
