Hi
This is my first attempt to do anything with radio so im a bit unsure how a
few things work.
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.

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.
Thanks,

What about those external speaker/mike combinations with built-in 1750Hz
tone generators? I've seen them in the ads in the german ham club
magazine cq-DL.

Maybe the toy shops still have those cheap plastic whistles where the
tone can be changed by moving a slider.

ftp to oak.oakland.edu and look in the directory "pub/hamradio/mods/alinco"
do an "ls dj580*" and you'll see a bunch of mods.

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.

The Lehigh University Amateur Radio Society
has a monochrome monitor for sale for $20.
It produces a very nice amber picture, but is
intermittant - you have to tap it every once
in a while to keep the picture.
Please respond by email, send a packet message to
N3GBD@WB3JOE.PA.NA, or call Bob at (610) 644-4173.
Thanks.

The FT-11 is Yaesu's newest super-small HT. Looks like a great radio. I just
wish I needed another HT!
