Haven't seen any around for years.

Once upon a time -- back in the early 1970's -- I built two 2-mtr FM
transceivers.

One was built from a kit sold by VHF Engineering, Rochester, NY. The
receiver consisted of four small rectangular PC boards that could be
assembled side-by-saide, one on top of the other, etc. Transmitter
was a small rectangular PC board that ran about 2 watts output. As I
recall, they also sold an amp with about 10 watts output. Crystal
controlled.

The other was built from a circuit in QST. Several suppliers sold
circuit boards and you had to dig around to find the parts. It was on
a single PC board -- may have been about 4 in X 8 in. Crystal
controlled.

But -- that was back in the days when men were men

Here are some links that may be helpful:

Hey OT:
Yeah in my dreams: I'm like to using a 74hc4066 pll has a 160mhz
bandwidth at 12 volts, a couple ne604/2 balanced de/modulator, slapped
in some tone boards, a keypad and decoder, a small color screen and a
pic cpu to run it all, for memory i'm using an USB flash drive.
Sweet.

Shouldn't you be dreaming of a 74HC4046 PLL, a 4066 is a quad
bilateral switch.

Hey OT:

That dream is just a throw back from the ole magazine days when they
always put in errors then 3 months later you gets the correction. Plus
a 74hc4046 can only run up to 7volts Vcc
So the correction would be running a 74hc4066 as a pll. One switch as
the VCO and a couple diode for the comparator. and another switch as
for the xtal OSC and another switch for a low pass filter.

Or if you do use a 74hc4046 you just upconvert and downconvert
everything and run it at 6 volts. Cause about 10Mhz is all you can
gets out of a 74hc40466 at 6 volts
