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: http://www.hobbytron.com/pdf/ft146E.pdf http://www.qsl.net/n/n5na//pages/1220/ |

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. 73 OT de n8zu |

Sweet. 73 OT de n8zu Shouldn't you be dreaming of a 74HC4046 PLL, a 4066 is a quad bilateral switch. Gary N4AST |

Gary N4AST 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 |
