OTA issue

[smackman]

I have one OTA channel that is bouncing in and out with signal. All the other OTA channels are fine. The funny thing is this same OTA channel is rock solid using my Televisions tuner. I actually put these 2 tuners up at the same time (PIP) and the 622 tuner shows the signal to be bouncing everywhere causing the picture to bounce in and out but the OTA tuner picture is solid. Irt actually shows 0 signal then bounces to 97% on my 622 tuner.
I have checked the coax from splitter. I have done a soft reboot. Nothing has helped. Its only on 1 ota channel and I receive 6 OTA stations. One station is at 64 and stays locked in solid. This one paricular channel is VHF (Channel 7); the rest are UHF. Any suggestions? This has not always been a issue.

You have a multi-path problem. Different tuners are affect differently. VHF is a longer signal and could bounce somewhat worse since it isn't dissipated as easily. I would suggest looking a AVS Forum to see if your area is listed. They may be able to help too.

CM 4228 can be prone to multi-path in certain situations.

You might consider adding either a VHF-high yagi or a channel 7 tuned yagi with a CM7777 pre-amp to get more directional signal from ch 7. You could then separately adjust the VHF antenna to tune out the reflections.
