Siltronix External VFO Model 90

Description

Thanks for looking and sold as is.
I did connect the VFO to my freq. counter and it was
functioning like I would expect but am not sure what freq.
I should be seeing since I don't have any docs. Did notice that the
frequency displayed on my freq.counter was stable.
No Returns.

This is a used item. This unit powers on and the screen comes on. We can change the screen displays by using the on-screen buttons and also the knob. We are not able to test it further, but it does come with a 30 day warranty. It only comes with what is shown in the pictures.
