The variation on range is controlled by the varactors. D21 through D26. Make certain you have the smaller 1SSV149 varactors at D21 and D22 and the larger ones at D23 - D26.
Check the soldering for those varactors and R30, R31, R32 and R33. 73, Don W3FPR On 9/4/2010 10:03 AM, KA1YMX wrote: > I am trying to adjust the VCO control voltage on the RF board and having an > issue.
