VFO run away


Francesca Wine
 


I am Francesca W7LTG ?on my Bitx 40 a modication of the VFO to slow down. ?I added 47k and a 300k resitor in series ?on the ?10k tunning pot ?green and yellow. Notice ?5k, 10k and 100k steps ?when at the ?beginning ?and end of the pot. By adding ?two monetary ?switch yellow to ground ?and green to ground ?will change the steps on tunning.?
? ?Previous ?i had one bad board from packing. Took a chance and bought ?another board. Be carefull ?to unwrap the bubble wrap and avoid ?static discharge. This will cause ?problems ?on tge VFO.?
