Ive managed to solder on the vco's but I am not getting the expected values for both pll tests. For the first one, I get 20 Hz as my frequency. For the second one, I get ~2.2 volts but it does not alternate to zero. I am ready to believe their must be someproblem with the VCO's, I hear noise from them, or maybe just one. Is there any way to check to see if the VCO's are working without using a spetrum analyzer? Also, I used a lot of solder on the VCO's because I had trouble getting them to stick to the board. If anybody has any ideas for me to try just let me know.
