Spent all of yesterday trying to figure out the problem with the low range value during the PLL reference oscillator range test. I removed the thermistor board as was suggested and checked the components for value and location and reheated any joints that looked even a little suspect. Still have a range of 8 Khz.
I've checked everything in the PLL area and all components are of the correct value and where they are supposed to be. Following suit as with the thermistor board I reheated any joints that might be considered suspect. I did find that R110 has a low value as compared to its color code. It is supposed to be 5.6K and it measures 3.7K. I don't think this low R110 value would affect the PLL reference oscillator range with it being in the variable bandwidth crystal filter circuitry. I have to be missing something here. Ideas? 73, Ed N0EHQ _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
