I have a pair of first generation Sony DSSt receivers with the UHF receiver option. The remotes have been very hit and miss lately so I replaced them with a newer model without much improvement.

Now one will only work if it is withing a few inches of the antenna, the other not at all.

The building they are in is a large residence with a fair amount of in the wall wiring for low voltage lighting and remote control blinds, etc.

Is it possible for the building's own electric circuits to be producing some king of jamming frequency?

It's not batteries, the UHF antenna is firmly plugged in and I have "reset" the box by unplugging for 5 min. etc.

Has anyone heard of this kind of symptom, and short of replacing the whole system, is there anything to try?

How about running a 50' extension wire for the antenna to bring within a few inches of the preferred viewing location?

Thanks

reading your description, it seems that the system was
working fine , then degraded.

Since you can operate only a few inches from the unit;
I suspect that you're working in the INFRA-RED domain
only.

Press MENU on your remote & go to the remote control page & see if the UHF mode is activated. Also check the
address matches the coding set in your remote.

If nothing else work's, Antenna extension trought coax
is a last resort option.

Thanks. I check those options.

I have had problems in the past with modulators interfering with the reception of rf receivers. the solution was to move the antenna away from the equip. location. I have been able to extend the antenna up to 250' without any problems.

Francis-
If youve already tried extending the ant with no success then try obtaining some 3dB attenuators for cable and attach them one at a time testing each time. It may be that there is too much RF interfering with the signal and attenuating the input may eliminate the interference. You will need a coax male to rca female adaptor and a coax male to rca female also.
