Carefully- if you force a slug and break it you may as well throw the radio in the bin as changing a
VCO is a painful exercise. They do break easily as they are only ferrite cores. Although the UHF ones
seem to be more robust than the VHF ones - adjust the VCO for 12v in receive mode and then for 12v
in transmit mode. See the following tables for more details. When adjusted the dot in the display should
not stay on after the TX is released. If you're lucky it won't come on at all. You may have to turn the set
on and off to reset the dot.
To adjust the receiver front end inject a 1 khz tone of 5khz deviation (2.5khz deviation for narrow band
sets) at your centre frequency and adjust the tuning slugs starting at L1 (the slug in the centre of the
board) through to L6 until the receiver is sensitive enough. See previous picture for location .You can
use a SINADDER or by ear.
