I'm seeing some funny results on Part II. I set up the 4 MHz oscillator by zero beating it with my Jupitor. The PLL reference oscillator showed:
High freq. 12100.48 Low freq. 12090.94 Range 9.54KHz This was pretty close to the value of 9.8 KHz and might be explained by the calibration method. The VCO test initially showed 8895.58 KHz and alignment was all within tolerance in table 6-1. On the BFO test the initial test showed 4912KHz nicely in range. Band+ and Band- taps gave no change at all. I have checked the soldering all roung the area and it seems good. The xtals installed at X3 and X4 are both marked ECS D 491-0433 and the varactors at D37 and D38 are V149s. I checked the BFO inductor for shorts and broken leads, they are all OK. Any ideas and suggestions would be most appreciated. 73, Pete/N9PT _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
