tvi
I was wondering if perhaps somone can help me figure out the best way to
track down why i suddenly seem to be giving myself some tvi i didn't make any changes, i had a tv in my shack i have more than one rig so it's not a bad rig seems the tvi is comming from within the room (not from the roof) my grounds seem same as always but the set really is totally wiped out even if i ut the rig to 1w the tv is totally overloaded sometimes the tv even seems sorta turn off if i key my cables to the rig seem ok same as always i seem to be missing something |

i would guess that you lost a ground connection on a coax. check all the
connectors and be sure the shields are all well connected. "ml" wrote in message ...

Something has changed in the vicinity. Has anybody parked a great
metal-clad vehicle near to your home? Or shifted anything else which could behave as a reflector of radio waves. Or has the room furniture, including the TV set, been changed around recently? Try changing the TV set. What happens? ---- Reg. ============================= "ml" wrote in message ...

Check the tv connectors....Sometimes the tv coax's center conductor gets a
bit of corrosion or the connectors get flakey. "ml" wrote in message ...

"Dave" wrote in message . .. i would guess that you lost a ground connection on a coax. check all the connectors and be sure the shields are all well connected. Not just the radio. Check the TV F connectors. It is easy to lose a ground there. The kind that push on, instead of screwing on to the set are especially bad. Try pushing the coax into the F connector while the TVI is present. If you have 300 Ohm twin lead, see if one side came loose. You didn't add a preamp, right? Tam/WB2TT "ml" wrote in message ...

thanks for all the help guys
while i made no changes in the shack i never thought of testing the tv coax ground thou i hand't meesed w/it could be it broke or the set it self is screwy i don't disturb other tv's which are very close to the one in my room and all fed off same main coax so for sure i've narrowed it down to my radio room off i go testing that tv coax ground appreciate the helps all!! |
