Wolfgang Hartmann Phase Lock Loop Simulator Program
I found a piece of software you can search engine for that simulates the operations of PLL chips used in CB and 10 meter rigs. You can search engine for it by "CB Simulator" also "cbsim 110". It works by PPL part number selection. I was tinking that those of you who are considering using PPL control of a simple Quad Receiver might check that out. Some of those chips have an accessory half channel function where you can move the frequency steps in 5 kHz spacings instead of 10 kHz. Again the same crystals I spoke of earlier such as the 10.240 MHz crystal here is the clock or divider crystal. I am going to order some toroid cores from Palomar or Amidon Associates, a kit of them I suppose and some dual gate mosfets and get down to seeing what works and what does not on the Mosfet mixers. What I am curious about is the arrangements on the core that produce 90 degree shifts some arrangements may produce 180 degree shifts for all I know. I can come up with a circuit here in a few days as a novelty circuit made up of vacuum tubes. A Pentagrid mixer seems like it might be a good choice for a vacuum tube quad detector. The I Q audio chain can be handled with 12AU6 or 12AX7 types of tubes. You might get it accomplished with two Pentagrid mixers tubes and one 12AUX7 since the 12AX7 is a dual triode and that can handle two audio channels. I know tha plate voltage supply will be around 250 to 300 volts for such and idea. Oh I found a software that analyzes your audio chain called "Oscillometer" the freeware version only runs 15 seconds at a time but thats all you need to analyze every thing form total harmonic distortion to signal to noise and a few other parameters. I thnk the authors name is Smellyoff from the Ukrane or Russia."Wolfgang Hartmann Dan _____________________________________________________________________ Call Anyone, Anytime, Anywhere in the World - FREE!
