Eico Model 315 SG
#10

Well, I replaced the Atten Resistors and buttoned up the unit.. I did a final check at 5 frequencies across the bands and recorded the values.. when I hit band F it wouldn't start to oscillate until about 20 mhz. From 13 Mhz thru 20Mhz No signal output.. that also was the case on the harmonics it didnt start to work until 90 mhz..

1st question What would cause the loss of frequencies and 2nd how do I improve the accuracy..
