VXR-7000 RX Issue

Post by w4zzk73 » Mon Apr 06, 2015 1:54 am

VXR-7000 Unknown Issue? PLL? VCO?

Video of my situation:

You can open the squelch and hear a cycling close of the squelch circuit... I have successful transmit for whatever frequency I program in, but absolutely no RX on the freq. Have attempted Duplex and Simplex programs. I have programmed two channels, one on the top end of the 70cm repeater ham band, and the other on the bottom end, and attempted to adjust the voltage on the RX board with no change in voltage at the Test Point on my DVM (per service manual instructions). Very odd here.

Above is a link to a video of the repeater I shot with sound... maybe you can hear what I hear in the opened squelch... By looking at the 'Busy' indicator, you may can see that it flickers along with the cycling sound in the open squelch... Watch and Listen closely... I'd appreciate any info!!

Any ideas?
