Homebrew of a 144 MHz FM transceiver using PLL synthesizer. Sunday, October 3, 2010. On the web I have found a lock detector circuit for the 4046. I may build this someday. For Now I use a TX delay when repeaters are used. A good low noise preamp may help to improve sensitivity. The sensitivity is not bad but my yeasu is better. I hope the sensitivity can reach the same level. Then I can use the repeater in Bregen op Zoom PI3BOZ. Friday, June 11, 2010. Tuesday, June 8, 2010.
Construction of spectrum analyzer using UDT-401 tuner. Strong harmonics are created internally when the signal level is high. Signals must be attenuated 20 db. This reduces dynamic range to 50 db. So, although dynamic range is 70db , only 50 db is available for measuring harmonics. I am adding dipswitches to the processor board. They will be used to set the calibration points for the horizontal calibration.
