My 25 year old Omni VI+ has gradually crept up 100 hz on the readout. I have a new TCXO that I recently purchased but I would like to make an adjustment to bring the BEAUTY UP 100hz so it will read

Be sure to check that the difference is seen on all bands, band crystals also change sometimes... de Wb8yqj Don My 25 year old Omni VI+ has gradually crept up 100 hz on the readout. I have a new TCX
Good advice from Don. Also, don't adjust anything until you first adjust the BFO oscillator trimmer capacitors, described in the manual under TX Audio Board. Master oscillator adjustment is described
And while you are checking the BFO frequencies, you may want to check your carrier suppression as well, esp. on LSB. All three Omni rigs in the shack only had -20dBc suppression on LSB until the two

OMNI VI+ rules for what I do - plain and simple. I have installed 2.8 Khz SSB filters and performed N1EU's audio tap. This is fed into my computer soundcard and the VI+ sounds as good if not better
The 10 Mhz reference oscillator (the TCXO you just replaced) and the BFO both have to be set correctly. There are several BFO adjustments and some of them interact with each other. So you may have to
